Questions people ask.
Does Locker encrypt photos on the device?
Locker's listing does not mention it. No encryption wording in the listing. Kryptis encrypts every file and its metadata with AES-256-GCM on the iPhone before it is stored.
Does Locker have a decoy vault?
Locker's listing does not mention it. 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 Locker?
Locker'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 Locker?
Locker's listing does not mention it. 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.
