Privacy Policy

Rollicon 3D ("the App", "we", "us", "our"), operated by Tranquil Mind Technology JSC, respects your privacy. This Privacy Policy explains what information we collect, how we use and share it, and the choices and rights you have. By using the App, you agree to this Policy.

Rollicon 3D is a live wallpaper app that turns the app icons you choose into 3D balls that roll, bounce, and react to your touch on your home screen. You do not need to create an account to use it.

1. Information We Collect

We do not ask you to create an account and we do not collect your name, email address, or contact details. The App collects the following automatically, through the third-party services listed in Section 3:

• Device and advertising identifiers — including the Google Advertising ID (GAID), device/installation identifiers, device model, operating-system version, and language, used for advertising, measurement, and analytics.
• Approximate location — coarse, IP-address-derived location (not GPS). The App does not request precise-location permission; our advertising and analytics partners may infer approximate location from your IP address for ad delivery and measurement.
• App activity / usage data — in-app events such as screens viewed, features used, and interactions, used to understand how the App is used and to serve and measure ads.
• Crash logs and diagnostics — crash reports, stack traces, and performance/diagnostic data to keep the App stable.

Processed only on your device (not collected by us)

• Photos you select. If you choose a custom background, the App uses the system photo picker to read the image you pick; that image is copied into the App's private storage on your device to render your wallpaper. It is not uploaded to us or any third party.
• List of installed apps. To let you choose which app icons roll on your wallpaper, the App reads the apps installed on your device and their icons on the device only. This information is used locally to build your icon selection and is not transmitted off the device.

2. How We Use Information

We use the information above to:

• provide, operate, and maintain the App and your wallpaper settings;
• display advertising (including, where permitted, personalized ads) and measure ad performance;
• analyze usage to understand and improve features and stability;
• detect, prevent, and address fraud, abuse, security, and technical issues;
• comply with legal obligations.

We do not use your information to build a profile that identifies you personally, and we do not knowingly process sensitive personal data.

3. Third-Party Services

The App uses the following third-party services, which may collect and process data as described in their own privacy policies:

4. How We Share Information

We do not sell your personal information for money. We share data only with the third-party services listed in Section 3 so they can perform advertising, analytics, attribution, and crash-reporting on our behalf or for their own permitted purposes, and we may disclose information where required by law or in connection with a business transfer.

5. Legal Bases (EEA/UK — GDPR)

• Consent — for personalized advertising and, where required, analytics.
• Legitimate interests — for core functionality, security, fraud prevention, non-personalized advertising, and product improvement.
• Legal obligation — where we must retain or disclose data by law.

6. Data Retention

We and our partners keep data only as long as necessary for the purposes above or as required by law. Advertising/analytics identifiers are retained according to each partner's retention periods; crash and diagnostic data are kept for a limited period to resolve stability issues.

7. Your Rights

Depending on where you live, you may have the right to:

• GDPR (EEA/UK): access, correct, delete, port, object to or restrict processing, withdraw consent, and lodge a complaint with your data protection authority.
• CCPA/CPRA (California): know, delete, and correct personal information; opt out of "sale"/"sharing" for targeted advertising; and not be discriminated against for exercising these rights.
• Other regions (e.g. LGPD, PIPEDA): equivalent rights under your local law.

Because the App has no account, we cannot look you up by name or email. To exercise a right, contact us at the email in Section 12 and, where relevant, include your advertising ID and device details so we and our partners can act on the request.

8. Children's Privacy

The App is intended for users aged 13 and older and is not directed to children under 13 (or the higher minimum age of digital consent in your country). We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will take appropriate steps to delete it.

9. International Data Transfers

Your information may be processed in countries other than your own, including the United States, where our service providers operate. Where required, we and our partners rely on appropriate safeguards (such as Standard Contractual Clauses) for these transfers.

10. Data Security

We use encryption in transit (HTTPS/TLS) and reasonable technical and organizational measures to protect information. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

11. Changes to This Policy

We may update this Policy from time to time. Material changes will be posted here with a new "Last updated" date. Your continued use of the App after changes take effect constitutes acceptance of the updated Policy.
