DiveTwin is a tool for overlaying and comparing two videos of the same dive. Your privacy is simple to describe: DiveTwin does not collect, store, or share any personal data.
None. DiveTwin has no accounts, no analytics, no advertising, and no tracking of any kind. We do not receive any information about you or how you use the app.
The videos you load stay on your device. All processing - syncing, overlaying, and exporting - happens locally. DiveTwin has no servers and makes no network connections, so your footage is never uploaded anywhere.
DiveTwin asks for access to your photo library only so that you can (1) choose videos to compare and (2) save an exported overlay clip back to Photos, if you choose to. This access is used solely for those actions on your device.
DiveTwin collects no data from anyone, including children.
