Privacy Policy
Last updated: July 2026
Satzly does not collect, store, or transmit any personal data. This policy explains what that means in practice.
No data collection
Satzly does not use analytics, advertising SDKs, cookies, or any form of tracking. No account, registration, or personal information is required to use the app.
Everything stays on your device
Your reading progress, flashcards, quiz results, grammar exercise history, and settings are stored locally on your device only, using Android's standard local storage. Nothing is uploaded to a server — Satzly has no server.
Export/Import
The "Export Progress" feature creates a local JSON backup file that you control — it is only shared if you actively choose to send it somewhere (e.g. via email or cloud storage) using your device's share function. Satzly and its developer never receive a copy.
Notifications
If you grant notification permission, Satzly may show a local reminder when flashcards are due for review. This is scheduled entirely on your device and involves no data transmission.
No third parties
Satzly does not share data with third parties, because no data is collected in the first place.
Your rights under GDPR
Because Satzly does not process personal data, most GDPR data-subject rights (access, rectification, erasure, portability) do not apply in the traditional sense — there is nothing held about you to request. You always have full local control: use "Export Progress" to obtain a complete copy of your data at any time, and "Reset Progress" (in Profile) to erase it from your device instantly.
Children's privacy
Since no personal data is collected from any user, this includes children.
Changes to this policy
If this policy ever changes — for example, if a future version of the app adds a feature that processes data differently — this page will be updated accordingly.
