Terms of Service — langusta.me

Last updated: 13 June 2026

1. Who we are

1.1. The langusta.me service is operated by SOFTBERRIES Krzysztof Grajek, ul. Zagonowa 1/1, 82-300 Elbląg, Poland, VAT ID (NIP): PL5782712816 (the "Provider", "we").

1.2. You can contact us at support@langusta.me.

1.3. These Terms of Service (the "Terms") are the regulations for services provided by electronic means within the meaning of article 8 of the Polish Act of 18 July 2002 on Providing Services by Electronic Means.

2. Definitions

2.1. "Service" — the langusta.me web application providing real-time voice conversations with an AI language tutor and a flashcard/vocabulary review system.

2.2. "User" ("you") — any person who creates an account and uses the Service.

2.3. "Consumer" — a User who is a natural person using the Service for purposes not directly related to their trade or profession. Where required by Polish law, provisions protecting Consumers also apply to a sole trader using the Service for purposes not of a professional character for them (a "przedsiębiorca na prawach konsumenta").

2.4. "Plan" — a free or paid subscription tier described in section 6.

2.5. "Minutes" — the voice-conversation time included in a Plan, metered per second of session duration.

3. The Service

3.1. The Service offers:
a) real-time voice conversations with an AI tutor in English, Spanish, French, German, Italian and Portuguese, adapting to your estimated CEFR proficiency level; and
b) flashcards and spaced-repetition review of vocabulary drawn from your conversations.

3.2. AI disclosure. Conversations in the Service are held with an artificial-intelligence tutor, not a human being. The tutor's voice is synthesized and its replies are generated by an AI language model. This notice is given in accordance with article 50 of Regulation (EU) 2024/1689 (the AI Act).

3.3. The AI tutor may make mistakes. The Service is a learning aid; it does not provide certified language instruction, examinations or qualifications.

3.4. Individual voice sessions are limited to 30 minutes. Minutes are metered per second of session duration, reset at the start of each billing period and do not roll over to the next period.

4. Technical requirements

4.1. To use the Service you need:
a) a device with internet access and an up-to-date web browser supporting WebRTC/WebSocket audio (current versions of Chrome, Firefox, Safari or Edge);
b) a working microphone and audio output;
c) a stable internet connection (voice quality depends on connection quality);
d) an active e-mail address.

4.2. The Service uses a strictly necessary authentication cookie and local browser storage, as described in the Privacy Policy. No analytics or advertising trackers are used.

5. Account and eligibility

5.1. Using the Service requires creating an account with an e-mail address or via Google sign-in.

5.2. The Service is intended for users aged 16 or older. By creating an account you confirm that you are at least 16 years old.

5.3. You are responsible for keeping your login credentials confidential and for activity on your account.

5.4. One account per person. Accounts are personal and non-transferable.

6. Plans, prices and payment

6.1. Available Plans:

6.2. Prices are stated in US dollars. Prices shown at checkout include applicable VAT.

6.3. Overage. You may optionally enable pay-as-you-go overage at $0.15 per Minute beyond your Plan's included Minutes. Overage is off by default, is subject to a monthly spending cap that you set yourself, and can be disabled by you at any time.

6.4. Payments are processed by Stripe. We do not store your card details. Invoices and receipts are issued and delivered through Stripe.

6.5. Annual Plans include the stated monthly Minutes allocation, which resets monthly.

7. Free Plan

7.1. The Free Plan gives you a one-time allowance of 10 voice trial Minutes and unlimited use of flashcards, without providing payment details.

7.2. The Free Plan is provided for an indefinite period. You may end it at any time by deleting your account (section 13.5).

8. Contract conclusion, renewal and cancellation

8.1. A contract for the Service is concluded when you complete registration (Free Plan) or when you complete checkout for a paid Plan.

8.2. Paid Plans are subscriptions that renew automatically at the end of each billing period (monthly or yearly) at the then-current price for your Plan, until cancelled.

8.3. You can cancel at any time through the Stripe customer portal available from your account settings. Cancellation takes effect at the end of the current billing period; you keep access and remaining Minutes until then. No further charges are made after cancellation takes effect.

8.4. Switching Plans takes effect as shown at the time of the change in the Stripe customer portal.

9. Right of withdrawal (Consumers)

9.1. As a Consumer you may withdraw from the contract within 14 days of its conclusion, without giving any reason.

9.2. To withdraw, send an unequivocal statement to support@langusta.me, for example using the model withdrawal form attached as the Annex to these Terms (you are not obliged to use the form). To meet the deadline it is enough to send the statement before it expires. We will confirm receipt by e-mail.

9.3. Immediate start of paid Plans. At checkout we ask for your express request that we begin providing the paid Service immediately, before the end of the withdrawal period, and we inform you that, if you then withdraw, you must pay for the service already provided up to the moment of withdrawal. If you withdraw after such a request, we refund the price paid minus a proportional amount for the service provided until your withdrawal; the remainder is refunded within 14 days using the same payment method.

9.4. Free Plan. The right of withdrawal also applies to the free contract. Since nothing was paid, withdrawal is exercised simply by requesting deletion of your account.

9.5. The model withdrawal form is also available as a separate document: https://langusta.me/withdrawal.

10. Acceptable use

10.1. You must not supply unlawful content through the Service. In particular, you must not use voice sessions or flashcards to transmit content that is illegal, infringes third-party rights, or is intended to harass or harm others.

10.2. You must not:
a) attempt to gain unauthorized access to the Service or its infrastructure;
b) interfere with or disrupt the Service, including by automated bulk access, scraping or reselling access;
c) attempt to extract, reverse-engineer or misuse the underlying AI models;
d) share your account or circumvent Minute metering or session limits.

10.3. We may suspend or restrict an account that violates this section, after notifying you by e-mail where reasonably possible, and may terminate the contract for material or repeated violations.

11. Conformity and complaints

11.1. We are liable to Consumers for the conformity of the Service with the contract under the statutory regime for digital services in chapter 5b of the Polish Consumer Rights Act of 30 May 2014. If the Service does not conform with the contract, you may demand that it be brought into conformity and, on the statutory conditions, demand a price reduction or withdraw from the contract.

11.2. Complaints can be submitted to support@langusta.me. Please describe the problem, your account e-mail and, where relevant, the date of the session concerned.

11.3. We respond to Consumer complaints within 14 days of receipt. If we do not respond within that time, the complaint is deemed accepted.

12. Liability

12.1. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including the Provider's liability toward Consumers and toward sole traders using the Service on consumer terms (przedsiębiorca na prawach konsumenta), and liability for damage caused intentionally, which is never excluded.

12.2. We are not liable for interruptions or degraded quality caused by force majeure, failures of third-party networks or your internet connection, or your equipment not meeting the technical requirements in section 4.

12.3. We may carry out scheduled maintenance. Where reasonably possible we will schedule it outside peak hours and announce it in advance. Maintenance does not reduce your Minutes.

12.4. Non-consumers only. Toward Users who are not Consumers (and not sole traders on consumer terms): (a) our total liability under the contract is limited to the fees you paid for the Service in the 12 months preceding the event giving rise to the claim; and (b) we are not liable for lost profits. These limits do not apply to damage caused intentionally.

13. Your content and intellectual property

13.1. The Service, including its software, design and content (other than your content), is protected by intellectual-property rights of the Provider or its licensors.

13.2. You retain rights to the content you provide (e.g. your speech during sessions). You grant us only the licence technically necessary to provide the Service, as described in the Privacy Policy. Voice audio is not recorded or stored; conversation transcripts are not stored after the session ends.

13.3. Your flashcard deck and learner profile remain available to you for the duration of your account.

13.4. AI-generated tutor responses are provided for your personal learning use.

13.5. You may delete your account at any time by e-mail request to support@langusta.me; deletion is executed within 30 days. Deleting your account ends the contract.

14. Changes to the Service and to these Terms

14.1. We may change these Terms for valid reasons, such as changes in law, changes to the Service's features, security needs, or changes to prices or third-party costs.

14.2. We will notify you of changes by e-mail at least 14 days before they take effect, indicating the effective date.

14.3. If you do not accept the changes, you may terminate the contract before the effective date (for paid Plans: with effect at the end of the current billing period, or by withdrawal/cancellation through the Stripe portal). Continued use of the Service after the effective date constitutes acceptance of the changed Terms.

14.4. Price changes apply only from the next billing period after the notice period in 14.2 has elapsed. You can always cancel before a price change takes effect.

15. Termination by the Provider

15.1. We may terminate the contract with 30 days' notice by e-mail if we discontinue the Service or a Plan. For paid Plans, we refund the proportional part of any prepaid period falling after termination.

15.2. We may terminate without notice for material or repeated breaches of section 10, after the suspension procedure in 10.3 where appropriate.

16. Out-of-court dispute resolution

16.1. If we reject a Consumer complaint, we will state in our response whether we agree to take part in out-of-court dispute resolution (ADR) proceedings and, if so, identify the competent ADR entity.

16.2. Consumers in Poland may, among other options, seek assistance from the Voivodeship Inspectorate of Trade Inspection (Wojewódzki Inspektorat Inspekcji Handlowej) competent for their place of residence and from the municipal or district consumer ombudsman (miejski/powiatowy rzecznik konsumentów). These options are voluntary for both parties.

17. Governing law and jurisdiction

17.1. These Terms are governed by Polish law. If you are a Consumer, this choice of law does not deprive you of the protection afforded by mandatory consumer-protection provisions of the law of the country of your habitual residence (article 6 of Regulation (EC) No 593/2008, Rome I).

17.2. Disputes with Consumers are resolved by the courts having jurisdiction under generally applicable law. For non-consumers, the court competent for the Provider's seat has jurisdiction.

18. Personal data

18.1. Information on how we process personal data, including the real-time processing of your voice during sessions, is set out in the Privacy Policy (`privacy-en.md`), which forms part of the pre-contractual information but not of the contract terms.

19. Final provisions

19.1. These Terms are available in English and Polish. The Polish version (`terms-pl.md`) is authoritative for Users contracting under Polish consumer law; for other Users, the English version applies.

19.2. If any provision of these Terms is found invalid, the remaining provisions remain in force.

19.3. These Terms are provided to you free of charge before contract conclusion in a form allowing storage and reproduction (downloadable Markdown/HTML).
