Effective date: August 1, 2026
23d GPS respects your privacy. Public users do not need an account. The app does not sell personal information, display advertisements, or track users.
Information we collect
23d GPS does not collect public users’ building searches, routes, favorites, or precise location. The app includes a restricted administrator feature used to update gate and road-access advisories. When an approved administrator signs in, the app and its service provider, Supabase, process the administrator’s email address, account/user ID, authentication information, and limited technical or security logs. Gate and road status updates submitted by an administrator are also stored so they can be shown across users’ devices.
How information is used
Administrator account information and technical logs are used only for authentication, app functionality, security, troubleshooting, and service reliability. This information is not used for advertising or tracking.
Navigation services
When you choose to navigate, 23d GPS opens Apple Maps, Google Maps, or Waze and passes the selected destination coordinates to that service. Information handled by the selected mapping app is governed by that provider’s privacy policy. 23d GPS does not receive route or location information back from those services.
Data sharing and retention
Administrator data is processed by Supabase as a service provider and is retained only as needed to operate and secure the administrator feature. Public gate and road status information is retained to provide current advisories. Personal information is not sold or shared for advertising.
Children’s privacy
23d GPS does not knowingly collect personal information from children.
Changes to this policy
This policy may be updated when the app’s features or data practices change. The effective date above will be revised when changes are made.
