Privacy
Your fishing. Your data.

Your logbook is stored locally. You have no public profile and your swims do not appear in a public directory.
Ready for your next device
With iCloud enabled, your records sync through the private storage of your own Apple Account. Sign in with the same account on a new device to bring your logbook with you. Allow sync to finish.

Can other people see my spots?
Your personal logbook is not public. In V3 you choose whom to invite and which records to include. Exact swim and bait-spot locations are separate choices, off by default.
What can my friend do with shared records?
In V3 an invited friend can view the shared snapshot without editing your records. You can revoke access later; this cannot remove screenshots or copies already made.
Does CarpAtlas work offline?
Your logbook is stored locally. iCloud sync, invitations and fetching maps or weather require a connection.
How reliable are the insights?
They depend on your records. The app shows sample counts and confidence. Fewer than five sessions or five catches is not enough for full analysis. More data helps, but does not guarantee a catch.
