Questions people ask.
Does Calculator# encrypt photos on the device?
Calculator#'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 Calculator# have a decoy vault?
Calculator# lists something close: Fake crash message, not a second vault. 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 Calculator#?
Calculator# lists it (Built-in browser to download files). 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 Calculator#?
Calculator#'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.
