Vaultmark: Photo & File Vault

Vaultmark keeps your private photos, videos and files locked in an encrypted vault on your phone. No account, no ads, no tracking. We collect nothing. 🔒 REAL ENCRYPTION, NOT JUST A HIDDEN FOLDER Everything you add is encrypted on your phone with AES-256-GCM before it's stored. Your pattern is protected with Argon2id and your phone's secure hardware, so the files can't be read without it, even by someone who copies the app's storage. Photos and videos are never handed to your gallery or any other app. ✍️ UNLOCK WITH A PATTERN Draw your pattern to open your vault. Wrong guesses get slower and slower, so guessing it isn't practical. ☁️ BACKUP TO YOUR OWN CLOUD Back up your vault to your own Google Drive. Only encrypted data leaves your phone, stored in a private app folder that only Vaultmark can see. There's no Vaultmark server. New phone? Restore your vault from its backup with your recovery phrase. 🔑 A RECOVERY PHRASE ONLY YOU HOLD When you create a vault, you get a 12-word recovery phrase. If you ever forget your pattern, it lets you set a new one. Nobody else has it, not even us. 📸 SECURE CAMERA Take photos inside the vault. They go straight in, never into your gallery. 📄 VIEW EVERYTHING INSIDE THE APP Look at photos, play videos and read PDFs and text files without leaving the vault. When you want a file back, take it out of the vault yourself. 🗂️ STAY ORGANISED Sort items into folders and filter by photos, videos or files. 🌗 LIGHT AND DARK Pick a light or dark theme, or let Vaultmark follow your phone. ⭐ VAULTMARK PRO • More vaults: each pattern opens its own vault • Disguise icons: make Vaultmark look like a Calculator, Printer, Units, Level, Network or Sound Meter app on your home screen • Duress pattern: if someone forces you to unlock, draw a second pattern. Your vault opens as usual, and your other vaults are erased from the phone (they can come back from their backup) • More folders in each vault • Import documents and other files (photos and videos are always free) Pro is a yearly plan with a 7-day free trial, or a one-time lifetime purchase. 🛡️ PRIVATE BY DESIGN • No account or sign-up • No ads, analytics or crash reporting • Your files never go to us. The only place Vaultmark sends data is your own backup, and it's encrypted • Screenshots are blocked and the vault is hidden in the recent apps screen Important: your pattern and recovery phrase are the only way into your vault. If you lose both, nobody can recover your files, including us. Keep your recovery phrase somewhere safe. Requires Android 10 or later and a screen lock on your phone during setup.
