Privacy Policy

Effective date: May 28, 2026 · Brushi by Sense Science Lab Ltd

This Privacy Policy describes how Sense Science Lab Ltd (“Senscilab,” “we,” “us,” or “our”) handles information in Brushi, our coloring app for children ages 4–6. We designed Brushi for the App Store Kids Category and take children’s privacy seriously.

1. Who we are

Brushi is published by Sense Science Lab Ltd. If you have questions about this policy, contact us at hello@senscilab.com.

2. Information we collect

We do not collect personal information from children. Brushi does not require an account, username, email address, or profile. We do not ask children to enter their name, age, location, or contact details.

We do not use third-party advertising networks and do not display behavioral ads in Brushi.

We do not sell personal information.

3. Information stored on your device

Brushi stores the following data locally on your device only:

  • Coloring progress and drawings — saved pages, free-draw artwork, and in-progress strokes so your child can continue later.
  • App preferences — such as background music volume, coach voice selection, and language choice.
  • Purchase state — whether Brushi Premium has been unlocked, verified through Apple’s StoreKit on your device.

This information stays on the device unless you explicitly choose to export a finished drawing (see Section 4).

4. Photo Library access

When a parent or guardian uses the Save feature, Brushi may add a finished coloring page to the device’s Photos library. Brushi only writes an image when Save is tapped; we do not read or upload your photo library. Saving is optional and can be controlled through iOS permissions.

5. In-app purchases

Brushi Premium is a one-time, non-consumable purchase processed entirely by Apple through your Apple ID. We do not receive your payment card details. Apple may collect purchase-related information according to Apple’s privacy policy. Parents must complete purchases; Brushi uses a parental gate before any purchase or restore flow.

6. Coach voice and on-device features

Brushi may offer an optional spoken “coach” that reacts to coloring activity. Coach responses are generated on the device from the current canvas image. We do not send your child’s drawings to our servers for this feature. Optional downloadable content, when offered, is delivered through Apple’s on-device resource systems and remains under Apple’s policies.

7. Analytics and tracking

We do not use third-party analytics or advertising trackers in Brushi. We do not track children across apps or websites. We do not request App Tracking Transparency permission because we do not engage in cross-app tracking.

8. External links

Brushi may link to this website (for example, Privacy Policy and Terms of Use). Opening an external link requires a parent or guardian to pass a simple adult verification gate inside the app.

9. Children’s privacy (COPPA and similar laws)

Brushi is directed to children under 13 and is designed to comply with the U.S. Children’s Online Privacy Protection Act (COPPA) and comparable laws. Because we do not collect personal information from children, we do not provide a separate parental consent flow for data collection—we simply do not collect it.

Parents and guardians may contact us at hello@senscilab.com with any questions or concerns about their child’s use of Brushi.

10. Data retention and deletion

Drawings and preferences remain on your device until you delete the app or remove saved content inside Brushi. Uninstalling Brushi removes locally stored app data from your device.

11. Security

Because Brushi keeps creative work on the device and does not operate child accounts on our servers, the primary way to protect your child’s content is to use your device’s passcode, Face ID, or Touch ID and to supervise app use.

12. International users

Brushi is available in multiple regions through the App Store. If you use Brushi outside your home country, your information still remains on your device as described above.

13. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the effective date at the top of this page. Material changes will be reflected here; please review this page periodically.
