Privacy Policy — Unlieng

Last updated: September 13, 2026 · App: Unlieng (com.unlieng.app) · Free English learning app, no account required.

This policy explains what data Unlieng collects and why. It is provided for Google Play (Data Safety / User Data policy) and Google AdMob review.

1. Data we collect

Data	Purpose	Shared with
Advertising ID, coarse location (country-level), app interactions with ads	Show personalized / non-personalized ads via Google AdMob; measure ad performance	Google (AdMob) — see Google Privacy Policy
Bookmarks, app language, theme (stored on-device)	Remember your saved words/phrases and preferences	Not shared — never leaves the device
Crash / diagnostic data (only if you enable system crash reports)	Fix bugs	OS vendor

We do not collect your name, email, precise location, contacts, photos, or files. No login. Unlieng is a general-audience app for users aged 13+ and is not directed at children under 13.

Permissions used: INTERNET only (to load ads and check connectivity). We do not request location, camera, microphone, or contacts permissions.

2. Consent (GDPR / EEA / UK)

On first launch in regions requiring consent (EEA/UK), the app shows a Google UMP consent form before loading ads. You can change your choice anytime via system Settings → Privacy, or by reinstalling the app (which resets the UMP state).

3. Data retention & deletion

On-device data (bookmarks, settings): deleted when you clear app data or uninstall.
Ad data held by Google: governed by Google’s retention policy.
There is no server-side account, so there is nothing to delete on our servers. If you need help, contact us below.

4. Children

Unlieng is not directed at children under 13. Where Google identifies child-directed traffic, ads are served with families-policy-compliant settings.

5. Data security

Ad-related data is transmitted over HTTPS by the AdMob SDK (encrypted in transit). On-device preferences never leave your phone.

6. Contact

Questions about this policy: support@unlieng.app.

Data Safety summary: collects Advertising ID, coarse location, and app interactions via the AdMob SDK for advertising and analytics; data is encrypted in transit; no account-deletion URL is required because no server account exists — on-device data is removed on uninstall / clear data.
