Privacy Policy

Call Vibe ("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.

Call Vibe is a caller ID, spam-call blocker, and unread-message tracker for Android. You do not need to create an account to use it.

1. Information We Collect

We keep data collection to a minimum. Some information is processed only on your device and never sent to us; other information is collected automatically by the third-party services that power analytics and advertising.

1.1 Data processed only on your device (not transmitted to us)

• Contacts. With your permission, the App reads your contacts to match incoming phone numbers to names for Caller ID. This matching happens locally on your device. We do not upload, store, or transmit your contacts to our servers or to any third party.
• Notifications. With your permission (Notification access), the App reads notifications to help you track unread messages. This is processed locally on your device and is not transmitted to us or to any third party.
• Call information for screening. Caller ID and call screening are performed on your device using Android's call screening service. The App does not read your call log and does not record calls.

1.2 Data collected automatically (transmitted off the device)

When you use the App, the following may be collected by us and/or our service providers:

• Device and advertising identifiers — e.g. the Android Advertising ID (AAID), Firebase installation ID, and similar identifiers.
• IP address and IP-derived approximate location — used for advertising, analytics, and security. We do not collect precise/GPS location.
• App activity and interactions — such as features used, screens viewed, and events, for analytics and advertising measurement.
• Crash logs and diagnostics — technical information about crashes and performance to help us fix problems.

We do not require you to provide your name, email, or other personal profile information to use the App.

2. How We Use Information

We use the information described above to:

• provide, operate, and maintain the App's core features (Caller ID, spam warning, call screening, message tracking);
• display and measure advertising, including personalized advertising where permitted;
• perform analytics to understand usage and improve the App;
• detect, prevent, and address fraud, abuse, and security issues;
• comply with legal obligations.

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 information only:

• with the third-party service providers listed in Section 3, so they can perform advertising, analytics, and diagnostics on our behalf or for their own permitted purposes;
• when required by law, legal process, or to protect rights, safety, and security;
• in connection with a business transfer (merger, acquisition, or asset sale).

5. Legal Bases (EEA/UK — GDPR)

Where the GDPR/UK GDPR applies, we rely on:

• Consent — for personalized advertising and, where required, analytics;
• Legitimate interests — for core functionality, security, fraud prevention, and improving the App;
• Legal obligation — to comply with applicable laws.

You may withdraw consent at any time (see Section 3).

6. Data Retention

We and our providers retain data only as long as necessary for the purposes described or as required by law. Advertising and analytics identifiers are retained according to each provider's retention policy; crash and diagnostic data are retained for a limited period.

7. Your Rights

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

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

Because the App has no user accounts, to help us locate the data associated with your device please include your Android Advertising ID and device details when you contact us at the email in Section 12.

8. Children's Privacy

The App is intended for users aged 18 and over and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided information to us, contact us and we will take appropriate steps to delete it. We handle age-related requirements consistent with COPPA and applicable EEA age-of-consent rules.

9. International Data Transfers

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

10. Data Security

We use encryption in transit (HTTPS/TLS) and other 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.
