PhysicsLab · Privacy Policy
1. What we collect
Nothing. The app has no account system, no sign-up and no analytics, advertising, crash-reporting or third-party SDKs.
You never have to enter a name, email address, phone number or any other identifying information.
2. Where your data lives
Scenes, objects, properties, conditions, graphs, steps and interface settings are stored in the app's private container on your device and never leave it.
Deleting the app deletes this data. We keep no backup and cannot restore it.
3. Network
The app makes no network requests and has no server. All simulation and drawing happen on your device, so it works in airplane mode.
If a future version adds an optional online feature (for example downloadable example scenes), it will be described in the release notes and this policy, and will be off by default.
4. Permissions
The current version requests no location, camera, microphone, contacts, photos or other system permissions.
If a future feature needs a permission, it will be requested only when you use that feature, with an explanation of why; declining will not affect other features.
5. Third parties
We do not share, sell or transfer your information to anyone. The app contains no advertising or analytics SDKs.
6. Children
The app is intended for people learning physics. It does not collect information from children and contains no child-directed advertising or recommendations.
7. Contact
If you have questions about this policy, email 250595214@qq.com — we usually reply within one or two business days.
