You must be at least 16 years old to use the Senthora AI platform ("the Service"). If you are under 18, or under the age of majority where you live, you may only buy a subscription or credits with the consent of your parent or legal guardian.

How we handle your personal data is explained in our Privacy Policy.

2. AI Service Terms & Synthetic Content

2.1. Nature of Output: Senthora uses AI models and synthetic voice technology from third-party providers (the full list is in our Privacy Policy). You acknowledge that: outputs are generated by a non-human entity, and synthetic voices are digitally generated and do not represent a real human being.

2.2. Accuracy & Reliability: AI can make mistakes. While we strive for linguistic precision, answers and corrections may sometimes be inaccurate, so please use your own judgement. The Service is for language practice and education. This does not affect your statutory rights as a consumer.

3. User Accounts & Security Responsibility

3.1. Verification: You must provide accurate registration data.

You can delete your account at any time in the app (Settings > Delete Account). Deleting your account does not cancel a subscription bought through Apple or Google; please cancel it in your store account settings.
