Privacy Policy

Sincelang · Effective 2026-07-23 · Last updated 2026-07-28

The short version

Sincelang works entirely on your device. We collect nothing, we run no servers that store your data, and we have no way to identify you. There are no accounts and no ads.


1. Data we collect: none

Sincelang does not collect, transmit, or share any personal information. There are no user accounts, and you do not need to sign in to use the app.


2. Where your data lives

Everything you do in the app — the words you learn, your review history, progress, streaks, and settings — is stored only on your device. This information never leaves your device and is never sent to us or to any third party.


3. No tracking, no ads, no analytics

The app contains no advertising and no third-party trackers. No analytics or telemetry data is collected from your device in the version distributed on the App Store and Google Play. We do not build a profile of you and have no way to identify you.


4. No internet required

Sincelang works fully offline. The app does not require a network connection to function.


5. Device permissions

If you choose to use voice-based practice features, the app may request microphone and speech-recognition access. Speech is processed to check your pronunciation and is not recorded, stored, or transmitted — no audio or transcript is saved. You can decline these permissions and continue using the rest of the app.


6. Children's privacy

Because the app collects no personal information, it is suitable for all ages. We do not knowingly collect data from anyone, including children.


7. Deleting your data

Since all data is stored locally, deleting the app removes all of your information from your device.


8. Changes to this policy

If we add features that change how data is handled (for example, optional cloud sync in the future), we will update this policy and the app store privacy information before that feature ships.
