This policy explains what personal data Echoteka processes, why, for how long and who else sees it. We collect as little as the service needs. We do not sell personal data and do not use it for advertising.

Temporary files created while a track is processed are deleted automatically. We never use your audio to train machine-learning models.

2. Where the data is kept

On our servers at Hetzner Online GmbH in data centres in the European Union. Encrypted backups of the database are kept in the EU for 10 days.

3. Who else receives data

AI suggestions. Preset suggestions and the text of the mastering report are generated by a third-party language model from numeric measurements of the track only — loudness, peaks, dynamic range, stereo width and spectrum balance. No audio, file names, account details or other personal data are sent to it.

4. Your rights

You may ask for a copy of your data, its correction, deletion or export, object to processing based on legitimate interest, and withdraw consent at any time — withdrawing does not affect processing done before. Write to support@echoteka.ai from the email of your account; we answer within one month. Closing your account deletes the account, its history and stored audio within 30 days, except purchase records the law requires us to keep; backups roll over within 10 more days.

You may complain to the Bulgarian Commission for Personal Data Protection (cpdp.bg) or to the data protection authority of your country.

5. Cookies and browser storage

Strictly necessary (no consent needed): your sign-in token, theme choice and a marker of a purchase in progress, kept in your browser's local storage so the site works. Analytics (only after you accept): Google Analytics cookies _ga and _ga_*, kept for up to 14 months. You can change your choice at any time with the "Cookie settings" link at the bottom of the home page, the app and this policy.

6. Children

Echoteka is not intended for anyone under 16, and we do not knowingly create accounts for them.

7. Changes

We will announce material changes in the app or by email before they take effect.
