Privacy Policy

derso is a learning platform with a talking AI teacher. Our privacy approach is simple: we do not collect more than needed, we do not sell your data for advertising, and we delete your data when you delete your account.

What do we collect?

• Account: name and email. Guest mode uses an anonymous device account without requiring email.
• Learning data: where you left lessons, study sessions, objective progress, and exam results.
• Questions you ask: transcripts are stored; voice recordings are not stored after transcription.

What do we not do?

• We do not sell your data or share it with ad networks.
• We do not use tracking cookies without consent.
• We do not keep a library of voice recordings.

AI and your data

Questions are sent to AI providers without direct identity details to generate answers. Enterprise API terms are used so this content is not used for model training by the provider.

Security

Data is transmitted over HTTPS and access is permission-based. Passwords are irreversibly hashed.
