5. Acceptance of the Terms is voluntary but necessary to use the Service.

§ 2. Types and scope of services

1. The Service is an educational platform for preparing for the Polish high school graduation exam (matura). Within the Service, the Provider offers:
   • access to educational content (questions, tasks, tests, study materials),
   • AI essay evaluation with feedback,
   • tracking of study progress, statistics, gamification (points, levels, streaks, achievements),
   • user leaderboard — a display of user results and activity showing name/nickname, avatar, XP points, level, streak, titles, and badges; users may hide their profile from the leaderboard in settings,
   • generation of personalized practice sessions (adaptive learning),
   • mock exam simulations,
   • study reminders (upon consent),
   • technical support.
2. The Provider reserves the right to modify, add, or remove Service features, subject to Users' acquired rights.
3. Services are offered in two variants:
   • Free variant — a free Account on which the User can: answer up to 10 questions a day in the Quiz (for an Account created on or after 14 October 2026, 16:30 Polish time — up to 5), in a chosen subject and section or topic, with graded answers and explanations (every question shown in the Quiz counts towards the limit, including skipped ones; the limit resets at midnight Polish time; the matura level, question type and number of questions can be chosen on the paid variant); use AI grading of open tasks in the Quiz within a monthly credit pool (§ 6(6)) — once it is used up, an answer to an open task can be compared with the model answer; and, once: solve one full exam paper without a time limit (open tasks graded by AI within the credit pool granted; the paper is available to Accounts that have never had Premium access), listen to 3 listening-practice recordings, and get one essay graded by AI (recordings and the essay on the website, not in the mobile app); the User may also use statistics, history and the leaderboard. In the mobile app the daily Quiz is available in app versions that support it; older versions keep the previous one-time free quiz. The free exam paper, recordings, essay and the monthly credit pool in the Quiz (the “starter pack”) are granted once per Account, once per device and once per Gmail address, and once per 30 days per network (does not apply to shared networks such as schools); on an Account without the starter pack the Quiz includes questions checked against the answer key, without AI grading of open tasks. Other features (in particular the Quiz without a daily limit, further exam papers, listening practice, essay grading and buying credits) require the paid variant;
   • Paid variant (Premium) — full access to all features, billed via subscription or as a one-time payment;
   • Seat access (Tutor Zone) — a Student's access solely to Assignments set by their Tutor, paid for by the Tutor (§ 19); does not include other Premium features.

§ 3. Technical requirements

1. To use the Service, the following are required:
   • a device with Internet access,
   • an up-to-date web browser (Chrome, Firefox, Safari, Edge in the current or one of the two previous versions),
   • an active e-mail address,
   • JavaScript and cookies enabled (at least necessary cookies).
2. The Provider does not guarantee correct operation of the Service on outdated browsers or devices not meeting the above requirements.

§ 4. Registration and user account

1. Registration in the Service takes place via a registration form (e-mail + password) or through Google account login.
2. Registration is free and requires acceptance of the Terms and the Privacy Policy.
3. When registering via e-mail, the User receives a 6-digit verification code sent to the provided e-mail address.
4. The User is obliged to provide true and current data and to keep the password confidential.
5. It is prohibited to maintain more than one account per person, resell account access to third parties, or share the account with third parties in order to circumvent Service limits.
6. Persons aged 13–17 may register an Account and use the Service only with prior consent and under the supervision of a legal representative (parent or legal guardian), who accepts the Terms on behalf of the minor User and is responsible for contract conclusion and payments.
7. The User may delete their Account at any time from the settings or by submitting a request to the Provider's e-mail address.

§ 5. Subscriptions and payments

1. Access to Premium features is paid. Current prices and plans are available on the Service website.
2. The Provider offers the following paid plans:
   • Monthly subscription (Premium) — PLN 49 per month, renewed automatically;
   • One-time access (30 days) — PLN 59, one-time payment, no automatic renewal;
   • Credit packages — according to the current Service offer (see § 6);
   • Tutor Zone Seats — monthly (PLN 49 per Seat), one-time for 30 days (PLN 59 per Seat) or one-time until 31 May, with volume discounts from 4 and from 10 Seats, purchased by a Tutor for the benefit of Students (see § 19).
3. Prices include all taxes (including VAT where applicable).
4. Payments are processed by Stripe Payments Europe, Ltd. Available payment methods: payment card, BLIK, Przelewy24 (instant bank transfer) and Revolut Pay. Recurring payments (subscription) are charged to a card or Revolut Pay — BLIK and Przelewy24 support one-off payments only. Payment data does not reach the Provider's servers.
5. The contract for the Premium service is concluded upon successful processing of payment by the payment operator.
6. A VAT invoice (or receipt) is issued upon the User's request submitted before the end of the month in which the payment was made. To receive a VAT invoice, the User should provide invoice details (including Tax ID, if applicable).

§ 6. Credits and one-time purchases

1. Credits are billing units enabling the use of selected Service features, in particular AI essay evaluations and other features requiring intensive computational resources.
2. The number of credits charged for a feature corresponds to the actual consumption of computational resources (including AI model and speech synthesis costs) needed to perform it. Using ready-made materials from the Service database (e.g. previously generated recordings and tasks) does not charge credits.
3. Prices and the number of credits in packages are available in the Service and may change, subject to acquired rights.
4. Credits have no validity period and do not expire. Credits purchased in a package are added to the Account balance immediately after the payment is booked. Credits can be used while the User has active Premium access (as well as for grading the free exam paper, § 2(3), and in the Tutor Zone under § 19); after access ends, the balance stays on the Account and can be used again once access is renewed.
5. An Account has a single credit balance — for credits included in Premium and purchased credits alike. At the start of each paid Premium period (subscription renewal, purchase of 30-day access, and every 30 days for the Matura Package — one-time access until 31 May) the balance is topped up to 600 credits if it is lower; if it is 600 or more, it stays unchanged. Example: a balance of 200 credits becomes 600 after renewal, while a balance of 900 stays at 900.
6. A Free Account (§ 2(3)) receives a separate pool of 10 credits for each calendar month, only for AI grading of tasks in the Quiz. The pool is topped up to 10 credits on the first day of each month (Polish time); unused pool credits do not carry over, and the pool is not combined with the balance under clause 5. The pool is granted to Accounts entitled to the starter pack (§ 2(3)).
7. Credits cannot be exchanged for cash, sold, or transferred to other accounts.
8. If the User terminates the contract (deletes the Account), unused credits are forfeited with no right to refund.
9. In case of a technical failure that prevents the use of credits or causes their loss, the Provider will restore the lost credits in the documented amount of loss.

§ 7. Automatic subscription renewal

1. The monthly subscription renews automatically every month until canceled by the User.
2. The User may cancel the subscription at any time from the Account panel. Cancellation does not result in immediate termination of access — the User retains access to Premium features until the end of the current billing period paid for.
3. The next payment will not be charged after subscription cancellation.
4. The Provider will notify the User of subscription renewal with appropriate advance notice, in accordance with the requirements of the Consumer Rights Act.
5. In case of a failed payment attempt, the Provider may retry charging at intervals. Lack of successful payment results in automatic termination of Premium access.

§ 8. Right of withdrawal

1. A Consumer has the right to withdraw from a contract concluded at a distance within 14 days of its conclusion, without giving any reason, in accordance with Art. 27 of the Consumer Rights Act.
2. To exercise the right of withdrawal, the Consumer should inform the Provider of their decision via an unambiguous statement, sent to kontakt@karol-leszczynski.pl or in writing to the registered address.
3. Loss of the right of withdrawal. Pursuant to Art. 38(13) of the Consumer Rights Act, the right of withdrawal does not apply to contracts for the supply of digital content not delivered on a tangible medium, for which the Consumer is obliged to pay a price, if the Provider commenced the performance with the Consumer's express prior consent, the Consumer was informed before the commencement of performance that after the Provider's performance they would lose the right of withdrawal, and the Consumer acknowledged this.
4. Upon activating a Premium subscription or purchasing credits, the Consumer gives explicit consent to the commencement of service provision (digital content delivery) immediately after payment and confirms awareness of the loss of the right of withdrawal. This consent is recorded in the Service system.
5. If the Consumer did not give the consent referred to in para. 4, access to Premium features will be granted only after the 14-day withdrawal period has elapsed.
6. A template withdrawal statement constitutes Annex 2 to the Consumer Rights Act and is available on request.

§ 9. Refund policy

1. Due to the nature of the services (digital content delivery) and the Consumer's informed and express consent to immediate commencement of performance (§ 8 para. 4), the Provider does not issue refunds for:
   • unused subscription periods (including subscriptions canceled during the billing period),
   • purchased one-time access (30-day) after Premium account activation,
   • purchased and unused credits,
   • the User's lack of activity in the Service,
   • the User's change of mind after commencement of performance,
   • matura exam results (there is no guarantee that using the Service will result in passing the exam with a specific score).
2. The Provider issues refunds in the following cases:
   • multiple, repeated charging of the same fee for reasons attributable to the Provider,
   • permanent inability to provide the service for reasons attributable to the Provider, lasting longer than 7 days and not resolvable within a reasonable time after reporting,
   • execution of a complaint resolved in the User's favor (§ 14).
3. Refunds are processed using the same payment method used for purchase, within 14 business days of acknowledging the request.
4. This section does not exclude or limit the Consumer's rights under mandatory legal provisions, in particular the warranty for defects and non-conformity of digital content with the contract (Chapter 5b of the Consumer Rights Act).

§ 10. AI-based features

1. The Service uses artificial intelligence models (in particular Anthropic Claude) to evaluate essays, generate explanations, adapt task difficulty, and provide other educational features.
2. The User acknowledges and accepts that:
   • results generated by AI are auxiliary, educational, and indicative, and do not constitute official exam grading;
   • AI may generate incomplete, imprecise, or in exceptional cases incorrect answers (so-called hallucinations) — the User should verify received information in source materials;
   • AI evaluations do not replace teacher or examiner assessments, nor the result of the matura exam organized by CKE (Central Examination Board);
   • AI evaluation criteria are based on published CKE criteria and educational guidelines but may differ from a human examiner's assessment;
   • the Service does not guarantee achieving a specific matura or other exam result;
   • the Provider is not liable for educational or life decisions made solely based on AI-generated results.
3. AI evaluations do not constitute decisions within the meaning of Art. 22 GDPR — they do not produce legal effects or significantly affect the User's legal situation. The User has the right to contest an AI evaluation and obtain an explanation of its basis.
4. It is prohibited to use the AI provided in the Service for purposes inconsistent with its intended use, including generating offensive, illegal content, content infringing copyright, or intended to unethically circumvent CKE criteria.

§ 11. User obligations

1. The User is obliged to use the Service in accordance with the Terms, applicable law, good practices, and principles of social coexistence.
2. The following is prohibited:
   • posting content that is illegal, offensive, discriminatory, or infringing the personal rights of others,
   • actions aimed at disrupting the Service (including DDoS attacks, code injection, scraping content without consent),
   • circumventing free access limits (including creating multiple accounts),
   • sharing the account with third parties or reselling access,
   • automated downloading of the Service's educational content for commercial purposes,
   • using the Service's content to train AI models without the Provider's consent,
   • misleading the Provider (e.g. false complaints, chargebacks).
3. Violation of the above may result in Account suspension in accordance with § 15.

§ 12. Intellectual property

1. All content made available in the Service (questions, tasks, educational materials, graphics, logos, source code) is protected by copyright and is the property of the Provider or entities with whom the Provider has concluded appropriate license agreements.
2. The User receives a non-exclusive, non-transferable license to use the Service's content solely for their own learning purposes, during the term of the contract.
3. Copying, distributing, publishing, modifying, or sharing the Service's content with third parties without the Provider's written consent is prohibited.
4. Content created by the User (e.g. essays) remains their property. The User grants the Provider a non-exclusive license to process such content solely to the extent necessary to provide the services (including sending it to AI models for evaluation).

§ 13. Provider's liability

1. The Provider exercises due diligence to ensure the Service operates continuously and reliably.
2. The Provider is not liable for:
   • technical breaks resulting from maintenance, failures, or force majeure,
   • incorrect Service operation resulting from the User's failure to meet technical requirements,
   • damages resulting from the actions of third parties (e.g. attacks, phishing),
   • matura or other exam results of the User,
   • educational, professional, or life decisions of the User based on the Service's content or AI evaluations,
   • AI-generated content in terms of its factual accuracy in exceptional cases (AI hallucinations),
   • data loss resulting from the User's actions (e.g. deleting the Account).
3. The Provider's liability towards a User who is not a Consumer for non-performance or improper performance of the contract is limited to the amount paid by the User in the last 12 months. This limitation does not apply to liability for damages caused intentionally.
4. This section does not limit the Provider's liability towards a Consumer to the extent such limitation would conflict with mandatory legal provisions.

§ 14. Complaints

1. Complaints regarding services provided in the Service may be submitted to: kontakt@karol-leszczynski.pl.
2. A complaint should include: the User's first and last name, the e-mail address assigned to the Account, a description of the problem, and the expected manner of resolution.
3. The Provider will consider the complaint within 14 days of receipt. Failure to respond within 14 days means the complaint is considered justified (in the case of Consumers).
4. In case of non-conformity of digital content with the contract, the Consumer has the rights under Chapter 5b of the Consumer Rights Act, including the right to demand that the digital content be brought into conformity with the contract or the price be reduced, and in certain cases — to withdraw from the contract.

§ 15. Contract termination and account suspension

1. The User may delete their Account at any time from the Service settings.
2. The Provider may suspend the Account or terminate the contract with immediate effect in the event of:
   • gross violation of the Terms,
   • actions threatening the security of the Service or other Users,
   • initiating a chargeback without prior attempt to resolve the issue,
   • using the Service in a manner contrary to the law.
3. Before suspending the Account (in non-gross cases), the Provider will call on the User to cease the violations with a deadline of no less than 3 days.
4. Account suspension for reasons attributable to the User does not entitle to a refund for the current billing period or for unused credits.

§ 16. Personal data protection

The rules for processing Users' personal data are set out in the Privacy Policy, which forms an integral part of these Terms.

§ 17. Changes to the Terms

1. The Provider may amend the Terms for important reasons, such as: changes in law, introduction of new Service features, changes in the manner of providing services, security considerations.
2. The Provider will inform the User of changes to the Terms with at least 14 days' notice, by e-mail or via a Service notice.
3. A User who does not accept the changes has the right to terminate the contract by deleting the Account before the changes take effect.
4. For subscriptions active at the time of change, changes unfavorable to the User take effect from the next billing period, unless the User consents to their earlier application.

§ 18. Dispute resolution

1. The law applicable to the Terms and to the contract concluded on their basis is Polish law. The choice of Polish law does not deprive the Consumer of the protection provided by mandatory provisions of the law of their habitual residence.
2. All disputes shall first be settled amicably.
3. A Consumer has the option to use out-of-court dispute resolution methods, including:
   • mediation at the Provincial Trade Inspection (Wojewódzki Inspektorat Inspekcji Handlowej),
   • the permanent arbitration consumer court at the Provincial Trade Inspection,
   • assistance from a municipal or district consumer ombudsman,
   • the European Commission's Online Dispute Resolution (ODR) platform: https://ec.europa.eu/consumers/odr.
4. Use of out-of-court methods is voluntary and requires the consent of both parties.
5. The court competent to resolve disputes is the court competent under the provisions of the Polish Code of Civil Procedure.

§ 19. Tutor Zone — special provisions

1. This section applies to the “Tutor Zone” feature (the “Zone”) and prevails over the other provisions of the Terms to the extent it modifies them.
2. Definitions: Tutor — a User who has created a Zone profile to teach Students (a Consumer or a business); Student — a User who has accepted a Tutor's invitation, holds their own Account and accepts the Terms personally (minors aged 13–17: § 4(6)); Seat — an entitlement purchased by the Tutor and assigned to one Student, giving that Student access to the Tutor's Assignments for the Seat's validity period; Assignment — work set by the Tutor: a question set (from the Service's question bank, AI-generated or written by the Tutor), a practice drill from the Service's question bank, or an exam paper; Materials — texts and files (PDF, TXT) the Tutor attaches as a basis for AI question generation.
3. Nature of the contract. The Tutor concludes a contract with the Provider under which the Provider also renders services to the Students designated by the Tutor (contract for the benefit of a third party, Art. 393 of the Polish Civil Code). Students pay nothing to the Provider. Settlements between Tutor and Student for tutoring take place outside the Service; the Provider is not a party to them and is not liable for the quality or course of tutoring.
4. Scope of a Seat. A Seat entitles the Student to (a) complete the Tutor's Assignments, (b) AI grading of open answers within Assignments up to the credit pool attached to the Seat per billing period as shown in the Service, and (c) view their own results. A Seat does not include any other Premium features (self-study outside Assignments, exam papers outside Assignments, essay grading, listening exercises); these require the Student's own Subscription. When a Seat expires or is released, the Student keeps their Account and result history and may finish Assignments started before that moment (including submitting a started exam paper), but can no longer start new Assignments.
5. Seat models (mirroring the Student plans in § 5(2); pools from all models add up):
   • Monthly Seats — a subscription for a chosen number of Seats at PLN 49 per Seat per month (PLN 39 per Seat for 4–9 Seats, PLN 29 for 10 or more — the rate depends on the total number of Seats in the subscription and is recalculated on every change), renewed automatically; § 7 applies. The Tutor changes the number of Seats in the payment operator's portal; increases take effect immediately, decreases from the next billing period. After cancellation, Seats remain valid until the end of the paid period and then expire. A Tutor may hold only one active Seat subscription at a time.
   • One-time 30-day Seats — a single payment of PLN 59 per Seat valid for 30 days from purchase (PLN 47 per Seat for 4–9 Seats in one purchase, PLN 35 for 10 or more), no renewal.
   • One-time Seats until the end of the exams — a single payment for a chosen number of Seats valid from purchase until 31 May of the current school year, no renewal. The price per Seat is calculated at purchase as: the number of calendar days from the purchase date to 31 May inclusive, less 30 days granted free of charge, multiplied by a daily rate of PLN 49 / 30 days, rounded down to the full złoty, reduced by 20% for 4–9 Seats and by 40% for 10 or more Seats in one purchase; the number of days, Seats and the price are shown before payment.
   Independently of the models above, a Tutor who has not yet purchased any Seat receives once a single trial Seat valid for 14 days from the moment the first Student joins their Zone; the trial Seat is subject to para. 4 and the Student assigned to it receives a limited pool of AI credits. The trial Seat covers question-set assignments and random questions from the bank; full matura exam papers are available only on purchased Seats. The trial Seat is granted once per User Account and once per network or device from which the Account was registered, and cannot be exchanged for other benefits.
6. Assigning Seats. The Tutor assigns and releases Seats independently and may reassign a released Seat to another Student within its validity. Releasing or not assigning a Seat gives no right to a refund. Seats may not be resold, exchanged for cash or transferred to another Tutor, and may be assigned only to persons the Tutor actually teaches.
7. Commencement of performance; withdrawal. § 8 applies to a Tutor who is a Consumer (or a sole trader protected as a consumer under Art. 385⁵ of the Civil Code). Performance is deemed to commence upon the earlier of: assigning the first Seat to a Student, or the first AI question generation. Until then the Consumer may withdraw within 14 days with a full refund. A Tutor who is not a Consumer has no right of withdrawal. § 9 applies otherwise.
8. Tutor Credits. AI question generation requires Credits purchased in packages under § 6. An estimated cost is shown before generation; the actual charge follows real usage (§ 6(2)). The Provider may grant a new Tutor a one-off free trial Credit pool (once per User), which is not part of the offer and may be changed or withdrawn without notice. Tutor Credits and the credit pool attached to a Student's Seat are independent. If generation fails for reasons attributable to the Provider, the charged Credits are restored under § 14.
9. Materials. By attaching Materials the Tutor warrants that they hold the rights necessary to use them for this purpose (in particular that no third-party copyright, e.g. of textbook publishers, is infringed) and bears sole responsibility for this, indemnifying the Provider against third-party claims. Materials containing personal data of third parties (e.g. named student work), unlawful content or content infringing personal rights may not be attached. Materials are sent to the AI provider solely to generate questions (§ 10; Privacy Policy), are not used to train models, are stored with the question set and deleted with it.
10. AI-generated questions are auxiliary within the meaning of § 10; the Tutor must verify them before assigning and is responsible for their selection. They are private — visible only to the Tutor and the Students they were assigned to — and are not added to the Service's public bank. The Tutor receives a non-exclusive, perpetual licence to use them in their own tutoring, also outside the Service (e.g. printouts), without the right to publish, sell or otherwise commercially distribute them as a collection. The Provider accesses them only for technical, security and complaint-handling purposes.
11. Student data and Tutor access. Upon acceptance of an invitation the Tutor gains access to the Student's: first name/nickname, e-mail address, last activity date, results and answers in Assignments (also live, while the Assignment — including an exam paper — is being solved, to the extent of answers saved in the Service), and the Student's overall learning progress in the Service (subjects, topics, practice sessions, exam papers and their results) — in order to tailor tutoring. The Student is informed of this scope before accepting; acceptance is voluntary. The Student may end the link at any time by asking the Tutor (removal from the Student list) or the Provider; from then on the Tutor loses access to the Student's data, while records of previously completed Assignments remain in both parties' history. The Tutor is an independent controller of the Student data obtained in the Zone and undertakes to process it solely for tutoring purposes, in accordance with the GDPR, not to disclose it to third parties, and — for a minor Student — to ensure the legal guardian is aware of the use of the Zone. Details: Privacy Policy.
12. Invitations. The Tutor may invite only persons with whom they have a tutoring relationship and, by entering an e-mail address, warrants that they are entitled to use it for this purpose. An invitation is a single e-mail with a link sent on the Tutor's behalf; the Provider sends no further commercial correspondence to the invitee and may limit invitations in case of abuse.
13. Notifications. The Service sends service notifications: to the Student about new Assignments and reminders of an approaching deadline of an unfinished Assignment (e-mail and app notification the day before, app notification on the day); to the Tutor when a Student completes the assigned work, about Assignments not completed on time and about the course of the trial Seat. Reminders are not sent to a Student without a valid Seat. They contain no commercial content and can be disabled in settings or with one click in the e-mail footer.
14. Prohibited in the Zone, in addition to § 11: (a) reselling or providing Seats to persons the Tutor does not teach, including offering Seats as a cheaper substitute for a Subscription; (b) generating questions to build collections for publication or sale outside the Service; (c) attaching Materials in breach of item 9; (d) inviting persons without their knowledge or against their will; (e) using Student data for purposes other than tutoring; (f) copying, downloading or collecting questions from the Service's question bank (including automatically or via multiple Accounts) for any purpose other than building Assignments for the Tutor's own Students. Breaches may result in blocking the Zone or the Account under § 15; Students keep their Accounts.
15. Termination. Deleting the Tutor's Zone profile or Account immediately expires all assigned Seats; Students keep their Accounts and result history. No refund is due for the unused validity of Seats, subject to § 9(2) and mandatory consumer rights.
16. Invoices. § 5(7) applies. A Tutor who is a business provides invoicing data (including tax ID) through the contact form in the Service panel or at kontakt@karol-leszczynski.pl; the invoice is issued on the basis of the payment operator's payment record.
17. Liability. The Provider makes the Zone available as a tool and is liable for its operation in accordance with the Terms. The Provider is not liable for the content of Materials, for the Tutor's selection and verification of questions, for the Tutor's use of Student data, or for the quality and outcomes of tutoring. § 13 applies accordingly.
18. Question bank in the Zone. A Tutor may browse the Service's question bank solely to build Assignments, within the daily limits on viewed questions and revealed answers shown in the panel. Full access to the bank (all result pages, search, random draws) is available to a Tutor who has purchased Seats, has an active Subscription or has at least one Student with a valid Seat, including a trial Seat; other Tutors see a sample of the bank. Limits and the scope of the sample may change to protect the bank against abuse; current values are shown in the panel. The Tutor may print or save as a PDF file the questions in their sets (from the bank, AI-generated and their own) — as a student worksheet and as an answer key — solely for the classes they teach. Publishing, selling or sharing such printouts or files outside those classes, in particular on the internet, is prohibited. Printouts carry the Tutor's name and the Service's mark; a Tutor who has purchased Seats or has an active Subscription may turn off the Service's mark.
19. Deadlines and exam time. The Tutor may set a deadline (a day) for an Assignment; it is completed on time if the Student finishes it by 23:59 Polish time on that day. The deadline is organisational: after it passes the Assignment remains available and the Service marks it as completed late. The Tutor may change the deadline and, when re-assigning work (“Do it again”), set a separate deadline for that Student. An exam paper assigned in the Zone is solved without a time limit unless the Tutor chooses the “as in the exam” mode — then the paper's time applies and the paper is submitted automatically, as saved, when the time runs out.
20. Tutor feedback about the Zone. The Tutor may send the Provider feedback about the Zone with screenshots and should not include Students' personal data beyond what is necessary to describe the issue. Feedback is used solely to develop and fix the Service.

§ 20. Final provisions
