Privacy Policy

Phonix ("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.

Phonix is a caller ID, spam-call blocking and message-notification tracking app for Android. You do not need to create an account to use it.

1. Information We Collect

1.1 Information processed only on your device (not collected by us)

The App's core features run entirely on your device. The following information never leaves your device and is not collected, transmitted, or stored by us or by anyone else:

• Contacts. With your permission, the App reads your contact list to identify callers, display your contacts and favorites, and match phone numbers you look up. Your contacts are processed in memory on your device only and are never uploaded to any server.
• Message notifications. With your permission (notification access), the App reads notifications from messaging apps (such as WhatsApp, Messenger, Instagram, and Telegram) to show you messages you have not opened yet. Notification content is stored only in the App's local storage on your device and is never uploaded.
• Spam and block lists. The phone numbers you add to your spam or block lists are stored only on your device.
• Settings and preferences. Your language, theme, and other preferences are stored only on your device.

You can delete all of the above at any time by clearing the App's data or uninstalling the App.

1.2 Information collected automatically

When you use the App, the third-party services listed in Section 3 automatically collect:

• Device and advertising identifiers, such as your Android Advertising ID and similar device identifiers.
• Approximate location derived from your IP address (city/region level). The App has no location permission and does not access GPS.
• App activity, such as screens viewed, taps, session frequency and duration, and interactions with ads.
• Crash logs and diagnostics, such as crash traces, device model, operating system version, and performance data.

1.3 Information you provide

The App has no account, registration, or in-app forms. If you contact us by email, we receive the information you choose to send (your email address and message content).

2. How We Use Information

• Provide and operate the App — core features run on-device; remote configuration keeps the App's settings up to date.
• Advertising and measurement — to serve ads (which fund the free App) and measure ad performance and install attribution.
• Analytics and improvement — to understand how the App is used and improve features and stability.
• Fraud prevention, security and compliance — to detect invalid ad traffic and abuse.
• Legal compliance — to comply with applicable laws and enforce our terms.

3. Third-Party Services

The following third-party services are integrated in the App and collect the data described in Section 1.2 under their own privacy policies:

4. How We Share Information

We do not sell your personal information for money. Information is shared only:

• With the ad, analytics, and attribution partners listed in Section 3, to the extent described above. Under some U.S. state privacy laws (for example the CPRA), the transfer of identifiers to advertising partners for personalized ads may be considered a "sale" or "sharing" — Section 7 explains how to opt out.
• For legal reasons, if required by law, regulation, legal process, or enforceable governmental request, or to protect our rights, users, or the public.
• In a business transfer, such as a merger, acquisition, or asset sale, in which case this Policy will continue to apply to previously collected data.

5. Legal Bases (EEA/UK — GDPR)

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

• Consent — for personalized advertising and, where required, analytics. You may withdraw consent at any time via the in-app consent dialog or system settings.
• Legitimate interests — for core App operation, security, fraud prevention, non-personalized advertising, and improvement, balanced against your rights.
• Legal obligation — where processing is required by law.

6. Data Retention

We do not operate our own servers and keep no user database. Our third-party partners retain the data they collect for the periods stated in their own policies (for example, Google Analytics for Firebase retains user-level data for up to 14 months; crash logs are retained for around 90 days). Data processed on your device (Section 1.1) remains until you clear the App's data or uninstall the App.

7. Your Rights

Depending on where you live, you may have the right to access, correct, delete, or port your data, to object to or restrict processing, to withdraw consent, and to lodge a complaint with your supervisory authority (GDPR/UK GDPR); or to know, delete, correct, and opt out of the "sale"/"sharing" of personal information and targeted advertising without discrimination (CCPA/CPRA and similar U.S. state laws); or equivalent rights under other laws (LGPD, PIPEDA, and others).

To exercise any right, email contact@tranquilmind.co. Because the App has no accounts, please include your Android Advertising ID (Settings → Google → Ads) and device model so we and our partners can locate data associated with your device. You can also act directly on your device: reset your Advertising ID, opt out of ads personalization, use the in-app consent dialog, or clear the App's data.

8. Children's Privacy

The App is intended for users aged 18 or older and is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us at contact@tranquilmind.co and we will work with our partners to delete it.

9. International Data Transfers

Our ad and analytics partners may process data in countries other than yours, including the United States. Where required, transfers are protected by safeguards such as the EU Standard Contractual Clauses or equivalent mechanisms maintained by those partners.

10. Data Security

Data transmitted by the SDKs described above is encrypted in transit using HTTPS/TLS. We and our partners apply reasonable technical and organizational measures; however, no method of transmission or storage is 100% secure.

11. Third-Party Apps, Content and Links

The App displays ads and may contain links that lead to third-party websites, apps, or services (including the messaging apps whose notifications it reads). Those services are governed by their own terms and privacy policies, and we are not responsible for them. Phonix is not affiliated with, endorsed, or sponsored by WhatsApp, Messenger, Instagram, or Telegram.

12. Changes to This Policy

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