Frequently asked questions

What encryption does PV document?

PV documents: "Data encryption", algorithm not named. Kryptis encrypts every file and its metadata with AES-256-GCM on the iPhone before it is stored.

Does PV have a decoy vault?

PV lists it (Fake password). In Kryptis a second passcode opens a separate vault with its own albums, and a third passcode erases everything.

Can I download videos from a link in PV?

PV's listing does not mention it. Kryptis downloads public photos, videos and streams from a pasted link straight into the encrypted vault, without touching the camera roll.

What happens if I forget my passcode in PV?

PV lists something close: Recovery email. Kryptis gives you a BIP39 recovery phrase when you set up the vault. It is the only way back in, and no one else holds a copy.
