Privacy Policy
Last updated: July 22, 2026
This Privacy Policy explains how Jazz Games (“Jazz Games”, “us”, “we”, or “our”) collects, uses, and discloses information when you use the Kera mobile application and related websites (collectively, the “Services”), contact our support staff, or otherwise interact with us.
We may change this Privacy Policy from time to time. If we make changes, we will revise the date at the top of this page and, when appropriate, provide additional notice. We encourage you to review this policy whenever you use the Services.
1. Who we are
Kera is operated by Jazz Games. For privacy questions or requests, contact us at hello@jazzgames.net.
2. Information we collect
Depending on how you use Kera, we may collect:
- Device identifier. An anonymous device UUID we generate and store on your device so we can sync your profile, progress, and purchases without requiring an account.
- Profile & onboarding answers. Information you choose to provide (for example goals, gender, age range, hair type, and questionnaire responses) to personalize your hair profile and routine.
- Hair photos (optional). If you choose photo check-in, photos you capture or select are uploaded briefly to our servers so our analysis service can generate lifestyle hair-care suggestions. Photos used for analysis are deleted from our storage shortly after processing. Analysis results (such as scores, profile summaries, and routines) may be retained to power your in-app experience.
- Progress & routine data. Check-ins, checklist completion, streaks, and related care activity you record in the app.
- Purchase & subscription data. Processed by Apple, Google, and our subscription partner RevenueCat. We receive entitlement status needed to unlock Premium features; we do not store full payment card details.
- Diagnostics & usage. Technical information such as device type, OS version, app version, crash logs, and approximate usage events via Firebase Analytics and Crashlytics, to keep the app reliable and improve the product.
- Advertising measurement (where permitted). With your permission on iOS (App Tracking Transparency) or via platform settings, we may use advertising identifiers to measure campaign performance. We do not sell your personal information.
- Support communications. Information you send when you contact us (for example by email).
3. How we use information
- Provide, operate, and improve Kera (profiles, routines, progress, Premium features)
- Run hair-photo analysis and deliver lifestyle care suggestions
- Process subscriptions and restore purchases
- Measure reliability, diagnose crashes, and understand feature usage
- Respond to support requests and enforce our Terms of Use
- Comply with legal obligations
Kera offers hair-care lifestyle suggestions, not medical advice. It does not diagnose or treat any condition.
4. How we share information
We share information only as needed to operate the Services, including with:
- Service providers such as Google Firebase (hosting, storage, analytics, crash reporting), Google Gemini (photo/questionnaire analysis), and RevenueCat (subscription status)
- App platforms (Apple App Store, Google Play) for distribution and billing
- Legal / safety recipients when required by law or to protect Jazz Games, our users, or others
- Business transfers in connection with a merger, acquisition, or asset sale
We do not sell your personal information.
5. Photo processing
When you use photo mode, images are transmitted securely to our backend, processed for lifestyle hair analysis, and then deleted from storage. We instruct our analysis systems not to identify the person in a photo. Analysis outputs are stored against your device identifier so you can revisit your profile and progress. You can also use questionnaire mode without uploading photos.
6. Data retention
We keep information for as long as needed to provide the Services and for legitimate operational, security, and legal purposes. You may request deletion of your hair-care data from within the app (Settings → delete data) or by emailing hello@jazzgames.net. After deletion, your device identifier may be retained solely so Premium purchases can still be restored.
7. Children
Kera is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have such information, contact hello@jazzgames.net and we will delete it promptly.
8. International transfers
Information may be processed in countries other than your own, including where our service providers operate. By using the Services, you understand that your information may be transferred to and processed in those locations in accordance with this Policy.
9. Your choices & rights
- Limit or reset advertising identifiers in your device settings
- Decline App Tracking prompts on iOS
- Delete your Kera data in-app or by contacting us
- Uninstall the app at any time using your device’s standard uninstall flow
Depending on where you live, you may have rights to access, correct, or delete personal information we hold about you. To exercise these rights, email hello@jazzgames.net.
10. Security
We use reasonable technical and organizational measures to protect information. No method of transmission or storage is completely secure; we cannot guarantee absolute security.
