This Privacy Policy describes how Undulation Calculator ("the App") handles information and data.
Undulation Calculator does not collect any personal information, location data, or usage statistics. The App operates entirely offline and locally on your device.
All data entered into the App (coordinates, altitude values, etc.) remains stored only on your device. None of this information is transmitted to external servers or third parties.
Undulation Calculator does not use any third-party analytics, advertising, or tracking services. The App does not integrate with any external services that would collect or transmit your data.
Undulation Calculator does not request or access your device's location services. All coordinates are manually entered by you and processed only on your device.
The App includes embedded geodetic data files (EGM96 geoid model and ETOPO1 terrain data) that are stored locally within the app bundle. These are static data files used for calculations and do not contain any personal information.
Undulation Calculator does not knowingly collect information from children. Since no information is collected, the App is safe for users of all ages.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. Since the App does not collect data, changes to this policy are unlikely.
Since Undulation Calculator does not collect or store any personal data, there is no data to access, modify, or delete. All your data remains under your complete control on your device.
If you have any questions about this Privacy Policy, please contact us through the App Store listing or your preferred method of communication.
