Privacy
Brushlings is built for children, and privacy is not a footnote. It is the foundation.
The short version
The Brushlings app collects no personal data, shows no ads, uses no trackers, and the camera image never leaves the device.
This website uses optional analytics cookies only if you accept them in the cookie banner. Without consent, we only store your cookie choice locally.
The Brushlings app
Everything below in this policy about cameras, photos, progress, and streaks applies to the iOS app only — not to your visit on this marketing website.
TrueDepth Camera & Face Data
Brushlings uses Apple’s TrueDepth camera and on-device face-tracking technology on devices with a TrueDepth front camera (e.g. iPhone X and newer). This is required for the live animal masks during brushing sessions.
What data is processed:
- Depth information and facial geometry / face-mapping data from the TrueDepth camera
- Live front-camera video frames, processed in real time only
- Approximate head position used for on-device brushing guidance (no separate face-ID or biometric login)
How we use this data:
- Only to display live animal masks on the user’s face and to provide brushing guidance inside the app
- Not used to identify or authenticate users, build profiles, or recognize individuals
- Not used for advertising, marketing, analytics, or data mining
- Not shared with third parties, affiliates, or data brokers
Storage, retention & deletion:
- TrueDepth / face-mapping data is processed only on the device in real time and is not uploaded to our servers or any third party
- We do not permanently store face maps, depth maps, or live camera frames
- If the user saves a mask photo, that photo is stored locally in the app gallery on the device only (see “Photos & Gallery” below)
- Deleting the app or resetting app data in iOS Settings removes all locally stored app data
Your choices & consent:
- Camera access (and therefore TrueDepth / face tracking) requires your permission via the iOS system prompt
- You can revoke permission at any time in Settings → Brushlings → Camera
- Without camera permission, live masks are unavailable; the timer and brushing guide still work
This section describes the app’s use of TrueDepth APIs as required by Apple’s App Store Review Guidelines (Guideline 5.1.1(i)).
Camera (general)
The live mask experience requires access to the front camera. Aside from optional locally saved mask photos, camera and face-tracking data are processed only in real time on the device. There is no transfer, upload, or permanent storage of live camera or face-tracking data.
Photos & Gallery
When your child takes a mask photo, it is stored locally inside the app. These photos are not uploaded and are accessible only on that device. They can be deleted at any time in the app gallery.
Progress & Streaks
Brushing progress, streaks, and unlocked masks are stored only locally on the device, so your child can continue where they left off. This information is not linked to a person and does not leave the device.
No accounts, no tracking in the app
- No registration and no user account are required in the app.
- No third-party analytics or advertising SDKs are used in the app.
- No location, contact, or identification data is collected by the app.
- There are no external links or purchases in the app that children can access unsupervised.

More information: Google Privacy Policy · Firebase Privacy
Children should use the Brushlings app, not browse this website unsupervised. The website is aimed at parents and guardians.
Children
The Brushlings app is designed for children with special care. Because the app does not collect or transmit personal data, use of the app does not create privacy risks for children. We follow the principles of the GDPR and guidance for kid-friendly apps.
App data storage & deletion
All data generated by the app exists only on your device. Deleting the app or resetting app data in iOS Settings removes all local app data completely.
Changes to this policy
If anything changes in how data is processed, we will update this page. Significant changes will also be communicated in an app update.
