About this app

Vowlock turns a private message into a small ritual. Set a password, or make them answer your question before the words unlock — or start a Pact, where everyone writes their own secret line, and no one (not even you, the person who started it) can peek until the whole group answers together. WRITE IT YOUR WAY - Lock a message with a password, or a question only they'd know the answer to - Stack up to three questions for a slower, sweeter reveal - Dress the encrypted text up with cipher styles — Morse code, letter swaps, emoji code, mirrored text — just for fun, layered on top of the real encryption underneath - Share the finished cipher anywhere: iMessage, Instagram, WhatsApp, wherever you already talk START A PACT - Invite a group. Everyone — including you — writes their own line and their own question, sealed on their own device - Nobody can unlock anyone else's part. Not the group, not the app, not even the person who started it - On the day you chose, pass the phone around and answer one by one - Only when everyone's answered does the full letter appear, one voice at a time, into a single keepsake BUILT FOR PRIVATE MOMENTS - Real AES-GCM encryption under the hood — the cipher styles are decoration, the lock underneath is real - Nothing is uploaded. Messages only ever leave your device through your own share sheet - No ads, no tracking, no account required Vowlock's core lock — passwords, single questions, one cipher style, and a full Pact — is free. An optional auto-renewable subscription unlocks extra cipher styles, dynamic-answer questions, premium reveal animations and card designs, plus a monthly certificate credit for your Pacts; a lifetime unlock and single Pact certificates are also available as one-time purchases. Subscription price and duration are shown before you buy and billed through your Apple ID; subscriptions renew automatically unless canceled at least 24 hours before the period ends — manage or cancel anytime in Settings > [your name] > Subscriptions.
