Terms of Service

Last updated: April 18, 2026

These Terms of Service ("Terms") govern your use of the Viglot mobile application and related services (together, the "Service") provided by Viktor Pergjoka, Kolonnenstr. 8, 10827 Berlin, Germany ("we", "us", "our"). By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

1. The Service

Viglot is an AI-assisted language learning app. It generates scenario-based practice material, provides spoken and written exercises, and tracks your progress. Some exercises use speech input; some produce text and audio content using artificial intelligence.

We continuously develop the Service and may add, change, or remove features. Access to specific features may depend on the device, the operating system version, your subscription tier, and the availability of third-party infrastructure.

2. Eligibility and Account Registration

You must be at least 16 years old (or the minimum age required in your country to provide consent to the processing of personal data) to use the Service. If you are under the age of majority in your country, you confirm that a parent or legal guardian has agreed to these Terms on your behalf.

You are responsible for keeping your account credentials confidential and for all activity that occurs under your account. Notify us at info@viglot.com if you suspect unauthorized access.

3. Subscriptions, Payment, and Renewal

The Service offers a free tier with limited usage and paid subscription tiers that unlock additional functionality and higher usage quotas. Paid subscriptions are processed through the app store you used to install the app (Apple App Store or Google Play) via our payment partner. Billing, receipts, and payment disputes are handled by the respective app store.

Automatic renewal: Subscriptions renew automatically at the end of each billing period unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time through your app store account settings.

Price changes: We may change subscription prices. You will be informed in advance, and changes take effect only from the next billing period. If you do not agree to a price change, you can cancel before it takes effect.

Trials: Free trial terms (duration, eligibility) are shown in the app when offered. Trials convert to paid subscriptions automatically unless canceled before the trial ends.

4. Right of Withdrawal (EU Consumers)

If you are a consumer in the EU, you have the right to withdraw from a paid subscription within 14 days without giving a reason (§ 355 BGB).

Exception for digital content: When you start using paid features immediately after purchase and expressly agree that we begin providing the service before the 14-day withdrawal period expires, you lose your statutory right of withdrawal once the service has started (§ 356 Abs. 5 BGB). The app asks for this express consent at the time of purchase.

To exercise withdrawal (where applicable), contact us at info@viglot.com with a clear statement of your decision to withdraw.

5. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any applicable law or regulation.
• Attempt to bypass, disable, or interfere with security, authentication, quota, or abuse-prevention mechanisms.
• Access the Service using automated means (scrapers, bots) except through interfaces we explicitly provide for that purpose.
• Submit prompts or inputs intended to extract, corrupt, or manipulate the AI systems that power the Service.
• Use the Service to generate content that is harmful, harassing, defamatory, infringing, sexually explicit involving minors, or otherwise unlawful.
• Resell, rent, or commercially exploit the Service or its outputs without our written consent.
• Reverse engineer, decompile, or attempt to extract source code from the app, except as permitted by applicable law.
• Create multiple accounts to circumvent usage quotas, trial limitations, or bans.

We may suspend or terminate accounts that violate these rules, with or without notice, depending on severity.

6. Your Content and Inputs

You may create custom courses and scenarios and provide inputs such as topics, vocabulary, and voice recordings. Content you create is stored privately to your account and is not shared with or made visible to other users of the Service.

You retain ownership of your original inputs. By submitting inputs to the Service, you grant us a non-exclusive, worldwide, royalty-free license to process, store, and transform them solely as required to operate the Service (for example, to generate exercises based on your inputs, to analyze pronunciation, and to improve your personal learning experience).

We do not use your personal inputs to train general-purpose AI models.

7. AI-Generated Content

The Service uses artificial intelligence to generate exercises, dialogues, explanations, and audio. AI-generated content can be inaccurate, incomplete, or inappropriate for your specific context despite our safeguards. You should not rely on AI-generated content for professional advice (medical, legal, financial) and should verify important information independently.

We make reasonable efforts to filter harmful outputs, but we cannot guarantee that every generated output is free of errors or inappropriate material. If you encounter problematic content, please contact us at info@viglot.com.

8. Intellectual Property

The Service, including its design, source code, branding, and pre-built learning materials, is owned by us and protected by intellectual property laws. These Terms do not grant you any ownership rights in the Service itself.

We grant you a limited, personal, non-transferable, revocable license to use the Service for private, non-commercial learning purposes for as long as you comply with these Terms.

9. Third-Party Services

The Service integrates with third-party platforms for authentication, payments, infrastructure, and diagnostics. Your use of features that depend on those platforms is also subject to their terms. We are not responsible for the availability, policies, or actions of those third parties beyond what our Privacy Policy describes.

10. Availability

We aim for continuous availability but do not guarantee that the Service will be uninterrupted, error-free, or available at any given moment. We may temporarily suspend the Service for maintenance, upgrades, or emergency reasons. Scheduled maintenance will be announced in advance where practical.

Except as required by mandatory law, the Service is provided on an "as is" and "as available" basis without warranties of any kind, express or implied, including fitness for a particular purpose or non-infringement.

11. Limitation of Liability

Nothing in these Terms limits or excludes our liability for:

• Injury to life, body, or health caused by our negligence or willful misconduct;
• Damage caused by intent or gross negligence;
• Liability under the German Product Liability Act (Produkthaftungsgesetz);
• Damages arising from the breach of essential contractual obligations ("Kardinalpflichten") — in which case our liability is limited to typical, foreseeable damages.

Any other liability is excluded to the extent permitted by applicable law.

12. Termination

You may stop using the Service and delete your account at any time via the in-app Settings or by contacting info@viglot.com.

We may terminate or suspend your account for material breach of these Terms, prolonged inactivity, or where required by law. Personal data will be deleted in accordance with our Privacy Policy. Content you created in the app may be retained in anonymized form after your account is deleted.

13. Changes to the Terms

We may update these Terms from time to time. Material changes will be communicated in the app and/or by email with reasonable advance notice. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms. If you do not agree with a change, you may terminate your account before it takes effect.

14. Governing Law and Jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods (CISG). Mandatory consumer protection laws of your country of residence remain unaffected.

For disputes with consumers, the place of jurisdiction is determined by applicable law. For disputes with merchants or legal persons under public law, the exclusive place of jurisdiction is Berlin, Germany.

The European Commission provides an online dispute resolution platform at https://ec.europa.eu/consumers/odr/. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.

15. Severability

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions continue in full force. The invalid provision will be replaced by a valid one that comes closest to the intended economic and legal effect.
