Encrypted storage where every vault has its own password.

A leaked password opens one vault at most.

In most cloud storage, whoever gets into your account gets all your files. Here your account pays for space and opens your home vault. Every other vault needs its own password or its 12-word recovery key, so a leaked email or account password does not open them.

You choose where each vault is kept.

On Android, every vault has two switches: a copy on the phone, and a copy in the cloud. You can change them later.

For when someone else has your phone.

Phones get stolen. Sometimes a person makes you unlock one. Here is what Stonesafe does about it.

• Vaults lock on their own. When you leave the app for the time you set, from 1 to 30 minutes. On a phone they also lock the moment the screen turns off.
• No fingerprint or face unlock. Nobody can hold the phone up to your face to open a vault.
• Nothing in screenshots. On Android, screenshots, screen recordings and the recent-apps view show a blank screen.
• Vaults that are not on the list. A vault with Phone copy off does not appear on the vault list. If you open the app for someone, they see the vaults you chose to leave there.

A notebook, a music player and a gallery, inside each vault.

Each vault opens as files, a gallery, a music player or a notebook. Viewers, players and sharing all work inside it, so a file rarely needs to leave.

Notes

Plain text or Markdown, with checklists and pins. Type on the phone and the words show on the computer a moment later.

Music and recordings

Folders with their covers, playlists, and the tracks you left halfway. It keeps playing with the screen off.

Photos and video

A gallery of every photo and video. Video streams, so you can skip ahead before the whole file arrives.

Papers and books

PDF, EPUB, text, tables and ZIP files open in the app, in the paper colour you like.

Links that end

Share one file with a link that ends after a time or a number of downloads, with a password if you want one.

Stonedrop

Send files from your device behind one link, without putting them in a vault first.

Android and the web, with the same vaults.

Sign in on either one with your email and password. The web app runs in a current browser on a computer or a phone, with nothing to install. The Android app is coming to Google Play.

• Open on both at once. A vault can be open on your phone and your computer together. Changes show on the other device as they happen.
• Folder backup on Android. New photos in a phone folder go into a vault by themselves, even while the vault is locked.
• Works offline on Android. A vault with a phone copy opens with no signal and syncs when it can.

You pay for storage. Every plan has every feature.

Only cloud copies count toward your storage. Vaults kept only on a phone are free.

What Stonesafe cannot do.

• If you lose a vault's password and its recovery key, nobody can open that vault again. That includes us.
• Malware that controls your phone can see what you open while a vault is open.
• Stonesafe cannot remove copies that already exist elsewhere, such as a photo your gallery app uploaded before you moved it into a vault.
• Your home vault opens with a tap on your own phone. The phone's screen lock guards it, so keep sensitive files in a vault with its own password.
