SkyMar: Privacy policy
Version 1.1.0 · build 6
Last updated: 10 September 2026.
SkyMar performs astronomical and magnetic calculations on your device. The app has no account, advertising, analytics, coach or AI assistant.
Position and saved settings
GPS is optional and requested when you choose “Use GPS”. Manual position entry works without permission. SkyMar does not track location in the background.
Your position, chosen time, heading and display preferences stay in app storage and are not sent to SL-Mar. Android may include app data in device backups according to your settings.
In-app updates
When you request an update check or download in SkyMar, it contacts slmar.co. The server receives normal connection metadata, but no position or calculation inputs. Downloads are verified before Android asks you to confirm installation. Calculations remain offline.
Links and website downloads
Website and email links open external applications. Downloading from slmar.co is a website request: the hosting and delivery services may process your IP address, user agent and request time. The existing counted download endpoint records those fields. This is separate from the offline app, which sends no usage analytics or location data.
Deleting data
Clear SkyMar's storage in Android Settings or uninstall the app to remove local data. Manage Android backups separately.
Earlier betas offered an optional external assistant. Its client has been removed, and saved assistant configuration is discarded when the new version loads. Data previously sent to another server is outside SkyMar's control.
