Privacy Policy

Last updated: August 30, 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 Yazılım Anonim Şirketi, a company registered in Türkiye, trading as Jazz Games (“Jazz Games”, “we”, “us”, “our”). For privacy questions or requests, contact us at hello@jazzgames.net.

2. Information we collect

Depending on how you use Kera, we may collect:

3. How we use information

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:

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.

Face data

Kera does not collect, generate, or store face data. The app analyzes photographs of your hair, which may include your face because hair is photographed on the head. Kera performs no face detection, face recognition, face matching, or facial landmark extraction; it creates no faceprints, face templates, or biometric identifiers, and it never uses a photograph to identify or authenticate anyone.

The hair-colour preview runs a segmentation model entirely on your device. That model labels each pixel as hair, skin, clothing, or background so that colour is applied only to hair; the labels are discarded when the preview closes and are never uploaded.

Hair analysis. Photographs you submit for hair analysis are transmitted over TLS to our backend on Google Cloud (region us-central1) and to the Google Gemini API, which performs the hair reading. Google does not use these images to train its models. The photograph is deleted from our storage as soon as the analysis returns; only the resulting scores and text are kept.

Hair-style preview. If you try a hairstyle on your own photo, that photograph is transmitted the same way to Google’s generative image model, which returns a new image of you wearing the selected hairstyle. The model is instructed to change the hair only and to leave your face, expression, skin tone, clothing and background exactly as they are, so that the result is recognisably you; nothing is measured, extracted, or derived from your facial features at any point, and no face detection or recognition is performed. The source photograph is deleted from our storage as soon as the render finishes or fails. The generated image is stored under your device identifier so it appears in your gallery, until you delete it.

Photographs you save to your hair journey are stored under your device identifier until you delete them individually or use Settings → Delete my data, which erases all stored photographs and analysis data. No photograph or face data is sold, shared for advertising, or disclosed to any third party other than Google as our processor.

Your control over photographs

Every photograph in the app is yours to remove: delete a single day from your hair journey, delete a generated image from your gallery, or use Settings → Delete my data to erase all photographs, analysis results and progress from your device and from our servers at once. Deleting the app removes the local copies as well.

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

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.
