Zero Trace Private Photo Vault

Zero Trace is a private photo vault and gallery vault. Hide photos, hide videos and lock files behind a password only you know. Everything is encrypted on your phone first, then backed up to your own Google Drive, Dropbox or OneDrive, so your private gallery follows you to a new phone and nobody else can open it.

Most gallery lock apps keep hidden photos on one phone. Lose the phone and the pictures are gone. Zero Trace is a secret photo vault with encrypted cloud backup, and your photos never pass through us: there are no Zero Trace servers, no account to create, no ads and no analytics.

HIDE PHOTOS AND VIDEOS
• Photo vault and video vault in one private gallery, with swipe, pinch to zoom and a built-in video player
• Import from your gallery and choose to remove the originals, so hidden pictures no longer show in your phone's gallery. Copies in other backup services are not touched
• Private camera: photos you take in the app go straight into the vault and never reach your gallery
• Organise your private photos with tags, favourites, sorting and search
• Select many items at once to tag, star or move them
• 30-day Trash, so a hidden photo deleted by mistake can be restored

FILE LOCKER, DOCUMENT SCANNER AND VOICE MEMOS
• File vault for PDFs, documents and any other file you want to lock
• Read PDF, Word, Markdown and text files inside the app
• Document scanner: scan pages into one PDF, saved straight into the vault
• Encrypted voice memo recorder, with the option to keep recording while the screen is off
• Share files into the vault from other apps

PRIVATE NOTES AND JOURNAL
• Encrypted journal for secret notes, with rich text, highlights and pinned entries
• Link entries to each other by title
• Import your notes from Notion or Obsidian

APP LOCK FOR YOUR VAULT
• Master password, plus fingerprint or face unlock
• Auto-lock when you leave the app, and shake to lock in an instant
• Intruder photo: a front-camera picture of whoever enters a wrong password, with a break-in log
• Screenshots and screen recording are blocked, and the preview in recent apps is blank
• Growing delays after repeated wrong passwords

ENCRYPTED CLOUD BACKUP IN YOUR OWN CLOUD
• AES-256 encryption on your device, before anything is uploaded
• File names, types and tags are encrypted too. Your cloud provider only sees scrambled data with meaningless names
• Stored in your own Google Drive. Add Dropbox and OneDrive accounts for more space
• Camera backup: new photos are encrypted and uploaded while the app is open and unlocked
• Keep files offline for flights and dead zones, still encrypted on your phone
• Storage overview and duplicate finder to free up space
• Get a new phone, connect your cloud account, enter your recovery phrase, and your photo vault is back

OPTIONAL DISGUISE
Zero Trace works as a normal vault app. If you want extra cover, you can switch these on in Settings:
• Calculator disguise: the app opens as a real, working calculator until you type your PIN
• A different app icon on your home screen: Calculator, Notes or Fitness
• Decoy vault: a second password opens a separate vault with different contents, to keep a casual look away from the real one

YOUR KEYS, NOT OURS
You hold a 12-word recovery phrase. No key is ever uploaded, and no password reset exists on our side, because we never have anything to reset.

RECOVERY: KEEP YOUR PHRASE SAFE
Your 12-word recovery phrase is the only way into your vault on a new phone. If you lose the phrase and your device, nobody can recover your files. Write it down and keep it somewhere safe.
