ClearDepth — Privacy Policy

We do not sell your data to third parties — ever.

Location & Background Alerts

Location is central to how ClearDepth keeps you safe on the water, so we want to be specific about how it is used.

While you are using the app, your location is used to centre the map on you, to let you tag a hazard at your current position, and to warn you when you come close to a hazard someone has flagged.

      Background location — only if you enable it
      ClearDepth can warn you as you approach a dangerous submerged hazard even while the app is closed or your phone is locked. To do that, the app monitors your location in the background. This is off by default. It is only ever turned on after we explain it and you explicitly tap to allow it, and you can turn it off at any time.
    

How background location is used: your device checks whether you have entered a zone around a nearby flagged hazard and, if so, shows you a notification. This happens on your device.

What we do not do with it: we do not continuously record or store a history of where you have been, we do not build a movement profile, we do not use your location for advertising, and we do not sell or share your location with third parties or data brokers.

Turning it off: open Profile → Notifications in ClearDepth and switch off Background Hazard Alerts. You can also revoke location permission entirely in your device settings (iOS: Settings → ClearDepth → Location; Android: Settings → Apps → ClearDepth → Permissions → Location). The rest of the app continues to work without it.

How We Use Your Data

To operate your account and authenticate you securely
To display your profile and contributions within the app
To show you hazards near your current location
To send proximity alerts as you approach flagged areas, including in the background if you have enabled that
To improve app reliability using anonymized crash reports

We do not use your data for advertising or share it with advertisers.

Data Retention

Your data is retained as long as your account is active. Hazard reports and chat messages you submit are stored and visible to other users of the same lake community.

If you delete your account, your profile data is removed. Some community contributions (hazard reports) may remain to preserve safety information for other users.

Your Rights

Access: You can view your profile data within the app at any time.
Correction: You can update your display name, boat info, and profile photo in the app's Profile tab.
Deletion: You can delete your account from Profile → Danger Zone → Delete Account. This removes your profile data from our servers.
Location: You can turn off background alerts in Profile → Notifications, or revoke location permission entirely in your device settings (iOS: Settings → ClearDepth → Location; Android: Settings → Apps → ClearDepth → Permissions → Location).
Data portability: Contact us to request a copy of your data.
