DotSafe help
How patterns, vaults, encryption, sync and sharing work, and what to do when something goes wrong.
How DotSafe encrypts your files
From the pattern you draw to the encrypted blocks on your device: the keys, the encryption, the padding and the cover files, step by step.
Plausible deniability, explained
Why DotSafe opens a vault for every pattern, keeps no list of vaults and hides real data among cover files. What this protects, and where it stops.
Setting up a decoy vault
A decoy vault is a normal vault that you are willing to show. How to make one that looks real, and the mistakes that give it away.
The duress pattern
A second pattern that erases every vault on your device and then opens an empty vault. How to set it, what it erases and what it keeps.
Sharing a vault safely
Share one vault with people you trust, with view or edit access. How invites and contact codes work, and what each person can see.
Backups and iCloud sync
With Pro, DotSafe keeps an encrypted copy of a vault in your iCloud and syncs it to your other devices. How to turn it on, restore a vault and turn it off.
Frequently asked questions
Short answers about forgotten patterns, limits, Face ID, plans, iCloud, deleting data and more.
How to choose a strong pattern
Your pattern is the only key to a vault, and no one can recover it. How to choose one that is hard to guess and easy for you to remember.

Contact
If your question is not here, email dotsafe@mobiusly.com. Do not send your pattern, and do not send private files. We never need them, and we cannot use them to open a vault.
If sync does not work, open the vault, then Settings. Tap Sync this vault, then Sync details. Copy the details and add them to your email. They contain no names and no files.
