What stays on your device
Your books, reading positions, highlights, notes, collections and statistics are stored locally. We cannot see your library, and there is no account to create.
The free version shows ads, which involve an advertising identifier and coarse technical data handled by Google's ad services. Buying Pro removes ads and the requests that serve them. OPDS catalogue connections go directly from your device to the catalogue you chose; we are not in the middle.
Who is responsible
Algorion OÜ (trading as Hetko), Tartu mnt 67/1-13b, 10115 Tallinn, Estonia, is the data controller. Contact: hi@hetko.eu.
What we collect
Crash and diagnostic reports; an advertising identifier and related technical data while ads are shown; purchase state from Google Play; and anything you choose to include in a support message. We do not sell personal data and we do not build advertising profiles of our own.
Why we process it
To keep the app working and fix it when it breaks (legitimate interest), to complete purchases and honour refunds (contract), and to show ads in the free version and answer support mail (consent, withdrawable at any time).
Processors we use
Google, for Play distribution, billing, crash reporting and advertising services, and our mail provider for support correspondence. Each acts under its own terms and may process data outside the EEA under standard contractual clauses.
How long we keep it
Crash reports for up to 90 days. Support correspondence for up to 24 months. Purchase records for as long as accounting law requires.
Your rights
Under the GDPR you can ask for access, correction, deletion, restriction or portability, and object to processing based on legitimate interest. Mail us and we answer within one month. You may also complain to the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon).
Children and changes
The app is not directed at children under 13. If this policy changes materially we note it here with a new date and in the app release notes.
