Privacy Policy

Conquer Physics needs no account or login. This policy explains what the app and content server actually handle.

What we collect

To download lessons and keep the service running, the app contacts our content server with a randomly generated installation identifier. The server records that installation identifier, the IP address, the country derived from the IP address, the platform (iOS or Android), the operating system version, the app version, first and last used times, and the request count.

Why we collect it

We use this data to deliver and protect content, verify access, understand overall usage, diagnose connection problems, and improve the service. We do not sell it and do not use it for cross-app advertising.

How long we keep it

Raw IP addresses and usage records are retained for 90 days; a record with no activity for 90 days is deleted. Access grants are retained until revoked.

Your learning data

Learning progress, answer history, and settings are stored only in a local database on the device and are never uploaded. Deleting the app deletes this local data. Downloaded lessons are cached on the device for offline use.

Third parties

We use Cloudflare as our content delivery network; Cloudflare processes connection information under its own policy. We do not provide data to other third parties except where required by law or necessary to protect the service.

Your choices

Email [email protected] to ask about, or request deletion of, data associated with your installation identifier. Deleting the app stops future connections; records already created remain subject to the retention period above.

What we do not collect

The app contains no ads and no advertising identifier, uses no cross-app tracking, and does not collect your name, email, phone number, contacts, photos, GPS location, or health data.
