What we store, and where
| Data | Where it lives | Uploaded? |
|---|---|---|
| Selected field & app settings | Your device only (local storage) | No |

| In-app purchase record | Apple App Store account | Handled by Apple |
| Network access | Purchase verification only (StoreKit) | Platform SDK only |
The shaders run entirely on your device's GPU using Metal. The light follows your finger locally — nothing about your interaction is recorded or transmitted.
What we don't collect
- × Your name, email address, phone number, or device identifier
- × Your location, contacts, microphone, or camera
- × Read access to your photo library — we only add files you choose to export
- × Advertising identifiers or cross-app tracking data
- × Any analytics, usage telemetry, or crash reporting — we ship no third-party SDKs for this
Photo library access
When you export a still or Live Photo, Flux requests permission to add to your Photos library — and only to add. It never requests read access, never browses your existing photos, and never sees anything in your camera roll. The file goes from the app to your album and nowhere else.
Third-party services
The only third-party integration is Apple's billing library, StoreKit, used to verify the one-time unlock. It's governed by Apple's own privacy policy. We add nothing on top of it.
Children's privacy
Flux is rated 4+ on the App Store. We do not knowingly collect information from anyone, including children under 13. Since we collect nothing, there is nothing to delete or request.
How to delete your data
Uninstall the app. Your selected field and settings are removed from your device with it. Wallpapers you exported live in your own Photos library and stay there until you remove them — they were always yours. We have no server-side data to delete, because we never had any.
Changes to this policy
If anything changes, we'll update the effective date above. Since we collect no personal data, any change is unlikely to affect you meaningfully.
