1. Who We Are
CNC Log Pro ("we", "us", or "our") operates the CNC Log Pro mobile application (the "App"). We are committed to protecting your privacy and handling your data responsibly.
This Privacy Policy tells you what data we collect, how we use it, who we share it with, and what choices you have. By using our App, you agree to the practices described here.
We do not sell personal data or sensitive user data to anyone. We only share data in the specific situations described in this policy.
2. What Data We Collect and Store
All data listed below is stored exclusively on your device. We do not have access to it, we do not upload it to any server, and we do not back it up to the cloud.

| Setup sheets and tooling data | SQLite database on your device | Until you delete it |
| Photos you add to projects | Local file storage on your device | Until you delete it |
| App preferences (language, currency, measurement units) | SharedPreferences on your device | Until you change them |

You can export all your data at any time using the backup feature in the app (Menu > Support > Backup). Uninstalling the app removes all local data permanently.
