Sharelock brings real privacy to the conversations you already have. Send a message that only your recipient can open. Lock it, and it stays sealed until they unlock it with their device's biometrics or passcode, right in the chat. Send locked photos too: they stay hidden until your recipient unlocks them, and you can delete any photo you sent, forever, whenever you want. No accounts, no sign-ups, and your photos are end-to-end encrypted, so no one but your recipient can open them. Nothing extra to install.
