This Privacy Policy applies to Natural Teeth Whitener (the "App").
Natural Teeth Whitener is built to work entirely on your device. The developer does not collect, store, or transmit your photos to any server. All photo editing happens locally on your device and is never uploaded, shared, or accessed by the developer or any third party.
The developer does not collect any personal information, photos, or usage data through this app. The app does not use analytics, advertising, or crash-reporting services. No account creation or sign-in is required.
If the app requests access to your Photos or Camera, this access is used solely to let you select, edit, and save images within the app. Photos you edit are processed and stored locally on your device only. The developer never sees, copies, or retains a copy of your images.
Natural Teeth Whitener uses Apple's on-device Vision framework to detect the mouth and teeth area in photos you select, so whitening can be applied automatically.
- What is processed: facial landmark positions (such as the mouth outline) in the photo you choose to edit. The app does not create face IDs, face templates, or any biometric identifiers, and does not recognize or identify people.
- How it is used: solely to locate the teeth area for whitening in the current photo.
- Storage and retention: face data is processed temporarily in your device's memory and discarded as soon as editing finishes. It is never saved to disk.
- Sharing: face data never leaves your device. It is not uploaded, stored on any server, or shared with us or any third party.
This app does not currently integrate any third-party SDKs, analytics tools, or advertising networks. If this changes in a future update, this Privacy Policy will be updated accordingly, and the effective date above will reflect the change.
This app is not directed at children under 13, and the developer does not knowingly collect personal information from children.
Because no data is collected or stored by the developer, there is no data to retain or delete. Any content created using the app exists only on your own device and is under your control.
This Privacy Policy may be updated from time to time. Continued use of the app after changes are posted constitutes acceptance of the updated policy.
In-app purchases and subscriptions are processed entirely by Apple through the App Store. The developer does not receive, collect, or store your payment information (such as card numbers or billing details) - this is handled directly by Apple in accordance with Apple's own Privacy Policy. The developer may receive limited, non-personal transaction information (such as whether a purchase was completed) solely to unlock features within the app.
