Privacy Policy
Whispr ("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.
Whispr is a caller ID, spam call blocker, and message tracker for Android that identifies incoming numbers, screens and blocks spam calls, and helps you re-open notifications you may have missed. You do not need to create an account to use the App.
1. Information We Collect
We collect only the data described below. Some features run entirely on your device and that data is not transmitted to us or any third party (see Section 2).
1.1 Collected automatically (leaves the device via third-party SDKs)
- Device and advertising identifiers — including the Android Advertising ID and similar identifiers used for advertising, analytics, and fraud/security.
- Approximate location — coarse, IP-derived location used by advertising partners for ad delivery and measurement. We do not collect precise/GPS location.
- App activity — in-app events and interactions (e.g. screens viewed, features used) for analytics and advertising measurement.
- Crash logs and diagnostics — technical information about crashes and performance to keep the App stable.
1.2 Processed on your device only (NOT transmitted to us)
- Contacts — used locally to match phone numbers to names for Caller ID. Your contact list is not uploaded to our servers; we have no server that receives it.
- Notifications you receive — read on-device via notification access so you can re-open messages you missed. This content stays on your device.
- Call and block/spam lists — the numbers you add are stored locally on your device.
We do not collect precise location, your photos, your microphone/camera, your SMS, or your call log.
2. How We Use Information
We use the information above to:
- Provide and operate the App (Caller ID, spam screening/blocking, missed-message viewing — the last three performed on-device).
- Serve and measure advertising, including personalized ads where you have consented.
- Perform analytics and improve the App.
- Detect, prevent, and address fraud, abuse, and security issues.
- Comply with legal obligations.
3. Third-Party Services
The App includes third-party SDKs that may process data as described above. Each has its own privacy policy:
| Service | Purpose | Privacy policy |
|---|---|---|
| Google Firebase (Analytics, Crashlytics, Remote Config) | Analytics, crash reporting, configuration | firebase.google.com/support/privacy |
| Google AdMob | Advertising | policies.google.com/technologies/ads |
| Meta (Facebook SDK & Audience Network) | Advertising mediation, app events | facebook.com/privacy/policy |
| Pangle | Advertising mediation | pangleglobal.com/privacy |
| Mintegral | Advertising mediation | mintegral.com/en/privacy |
| AppLovin | Advertising mediation | applovin.com/privacy |
| Adjust | Attribution and marketing analytics | adjust.com/terms/privacy-policy |
| Google Play services | Core platform services | policies.google.com/privacy |
4. How We Share Information
We do not sell your personal information for money. We share data with the third-party services listed in Section 3 for the purposes described.
U.S. state privacy laws. Sharing device/advertising identifiers with advertising partners for personalized advertising may be considered a "sale" or "sharing" of personal information under certain U.S. state laws (e.g. California's CCPA/CPRA). You may opt out of personalized advertising using the ad-consent and advertising-ID controls described in Section 3.
We may also disclose information for legal reasons (to comply with law or lawful requests) or in connection with a merger, acquisition, or asset transfer.
5. Legal Bases (EEA/UK — GDPR)
- Consent — personalized advertising and, where required, analytics.
- Legitimate interests — core functionality, security/fraud prevention, and App improvement.
- Legal obligation — compliance with applicable law.
You may withdraw consent at any time (see Section 3).
6. Data Retention
We keep data only as long as necessary for the purposes above or as required by law. Advertising and analytics partners retain identifiers according to their own policies; crash and diagnostic data are kept for a limited period.
7. Your Rights
GDPR (EEA/UK): access, correction, deletion, portability, objection, restriction, withdrawal of consent, and the right to lodge a complaint with a supervisory authority.
CCPA/CPRA (California) and similar U.S. state laws: the right to know, delete, and correct; to opt out of the "sale"/"sharing" of personal information and targeted advertising; and to non-discrimination for exercising your rights.
Other regions (e.g. LGPD, PIPEDA): equivalent rights under your local law.
Because the App has no account, to exercise a request please email us (Section 13) and include your Advertising ID and device details so we can identify the relevant data. We will respond as required by applicable law.
8. Children's Privacy
The App is intended for users aged 13 and older and is not directed to children under 13. We do not knowingly collect personal information from children under 13 (or the higher minimum age of digital consent in your region). If you believe a child has provided us data, contact us and we will 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 Advertising Content
Ads shown in the App are provided by third parties and may link to external content or websites we do not control. We are not responsible for the content or privacy practices of those third parties; please review their policies.
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.
