Privacy Policy

Effective Date: May 21, 2026

This Privacy Policy explains how ExCaller collects, uses, and protects your information. We value your privacy and are committed to protecting your personal data.

1. Open-Source & Transparency Statement

ExCaller is an open-source software under the MIT license. We firmly believe in code transparency and community trust.

• Source Code Availability: The full source code of ExCaller is publicly available, allowing anyone to audit the codebase to verify its security and privacy compliance. You can inspect the source code at our official repository.
• Third-Party Components: ExCaller may utilize other open-source third-party libraries during development. We strictly comply with these open-source licenses, and none of these components collect your personal private data.

2. Information We Collect

ExCaller does not collect any personally identifiable information (such as your name, email address, phone number, precise location, or device identifiers).

To optimize user experience and improve the functionality, ExCaller collects fully anonymous user behavior statistical data by default. This data includes:

• App opening and closing frequency
• Use of specific features (e.g., how many times the settings panel is opened)
• App version update status

This data is completely anonymous and cannot be used to identify or track any specific individual.

3. How We Use the Information

The sole purpose of collecting this anonymous data is to:

• Analyze the popularity of various App features to improve the product in future updates.
• Count the number of active users and evaluate App performance.

We will never sell, rent, or share this data with any third party for commercial or advertising purposes.

4. Your Control and Opt-Out Options

We respect your choice. If you do not wish to send any anonymous statistical data to us, you can turn off this feature at any time by:

1. Open ExCaller
2. Click the blue button with gear icon
3. Find the "Anonymous Statistics" option, toggle it off.

Once you disable this option, ExCaller will immediately stop collecting and sending any behavioral data.

5. Data Security

Since we do not collect any personal information, there is no risk of your personal privacy data being leaked. For the collected anonymous statistics, we use industry-standard encryption and security measures for transmission and storage.

6. Children's Privacy

ExCaller does not knowingly collect any personal information from children under the age of 13 (or the legal equivalent age in your country). If you are a parent or guardian and find that your child has provided personal information to us, please contact us via the email below.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective Date" at the top. You are advised to review this Privacy Policy periodically.
