Your privacy is our priority

Last Updated: January 01, 2026

Our Commitment to Your Privacy

At Callio, your privacy is our top priority. We designed Callio from the ground up with your privacy in mind. This app is safe to use because we don't collect, store, or share any of your personal information.

Data Collection

We do not collect any personal data. Callio operates entirely on your device. Your call logs, contacts, and usage patterns are never transmitted to our servers or any third parties.

No Login or Account Required

You don't need to create an account or provide any personal information to use Callio. No email, no phone number, no tracking. Just install and use.

Local Storage

All randomized names and call logs are stored locally on your device. You have complete control and can clear this data anytime from the Settings page within the app.

No Third-Party Sharing

We never share your data with:

  • Advertisers
  • Analytics companies
  • Data brokers
  • Any other third parties

Your privacy is not for sale.

Advertising

Callio displays advertisements to support the free version of the app. However, we do not collect or share your personal data with advertisers. Ads are served through third-party ad networks, which may use non-personal information such as your device type and general location (country/region level only) to show relevant ads. No call logs, contacts, or usage patterns are ever shared with ad networks.

Premium subscribers enjoy an ad-free experience.

Subscription & Payment Information

Subscriptions are processed through the Google Play Store. We don't handle or store your payment information. Your billing is managed securely by Google.

Permissions

Callio requires certain Android permissions to function:

  • Phone/Call Logs: To display randomized names in your call logs
  • Contacts: To map randomized names to your contacts (data never leaves your device)

All permissions are used solely for the app's functionality and no data is ever transmitted externally.

Cookies & Tracking

We do not use cookies, analytics, or any tracking technologies. We have no idea how you use the app, and that's by design.

Children's Privacy

Callio does not knowingly collect information from children under 13. The app is designed for general audiences.

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last Updated" date.
