Privacy Policy

1. Who We Are

EasyZero is developed and published by Cervine Studios. This Privacy Policy explains how the EasyZero mobile application ("App") and this website ("Site") collect and use information when you interact with them.

If you have questions about this policy, contact us at [email protected].

2. Information We Collect

The App does not require an account and collects no personal information during normal use. The following data stays entirely on your device:

• Target photos — Images you capture or import are processed locally using on-device machine learning.
• Analysis history — Group statistics, scope correction results, and reference line data are stored in local app storage only.
• App preferences — Settings such as your preferred correction unit (MOA, MIL, clicks) are stored locally.

The App does not upload, transmit, or share any images or analysis data. Nothing you capture or import ever leaves your device.

This website is a static page. It does not use cookies, tracking scripts, or analytics.

3. Camera and Photo Library Access

The App requests the following device permissions:

• Camera — Used to photograph targets directly within the App. Required only when you choose to capture a new photo; you can also use existing photos from your library without granting camera access.
• Photo Library (read) — Used to select existing target images from your photo library for analysis.
• Photo Library (write) — Used to save annotated or cropped images to your photo library at your request.

You can revoke these permissions at any time in your device's Settings. Revoking camera access does not affect your ability to analyze photos already on your device.

4. How We Use Information

All core App functionality runs entirely on-device:

• Bullet-hole detection runs via an on-device TensorFlow Lite model.
• Scope correction calculations are computed on-device using your scale reference and aim-point inputs.

5. Data Sharing and Third Parties

We do not sell data. We do not share data with advertisers or data brokers. We do not operate any servers that receive your photos or analysis data.

The App is distributed through the Apple App Store and Google Play Store. Apple and Google may collect usage diagnostics or crash reports subject to their own privacy policies, which are independent of this policy.

6. Data Retention and Deletion

Data stored on your device (history, preferences) can be deleted by uninstalling the App. Individual sessions can be deleted from the history screen.

7. Children's Privacy

EasyZero is not directed at children under the age of 13. We do not knowingly collect any personal information from children.

8. Security

On-device data is protected by your device's security model (iOS Keychain, Android Keystore, OS-level file protection).

9. Changes to This Policy

If we update this policy, we will revise the "Last updated" date above. For material changes, we will provide additional notice within the App or on this page. Continued use of the App after any change constitutes acceptance of the updated policy.
