All project information entered into the application remains stored locally on the user's device.
Local Data Storage
Any project data you create in the application, including trench calculations, project names, and related information, is stored only on your device.
The developer does not have access to this data.
Users may optionally create backup copies of exported files (such as CSV or PDF reports) and store them using their own cloud services or email systems. Any such storage is managed entirely by the user and is subject to the privacy policies of the services they choose to use.
File Exports
The application allows users to export project data as:

PDF reports
These files are generated locally on the device and may be shared using the device’s built-in sharing features (such as email or cloud storage apps).
Trench Calculator does not transmit exported files to the developer or any third party.
Permissions
Trench Calculator may request limited device permissions solely for the purpose of enabling file exports and sharing.
These permissions are used only to allow the user to:
Save exported files
Share exported reports through other applications
No permissions are used to collect personal data.
Third-Party Services
Trench Calculator does not integrate with any third-party analytics, advertising networks, or tracking services.
Advertising
Trench Calculator does not display advertisements and does not include any advertising networks.
Children's Privacy
Trench Calculator does not knowingly collect personal information from children under the age of 13. Because the application does not collect any personal information from users, it is compliant with children's privacy protections.
Data Security
Since all project data is stored locally on the user’s device, users maintain full control of their information. Users are responsible for protecting access to their device and any exported files.
