Questions
Where are my files kept?
On your iPhone, inside Lagrange. They are not uploaded anywhere unless you send them somewhere yourself.
Do I need an account?
No. Lagrange has no account and no sign-up. Cloud places such as Google Drive are optional and use your own account with that service.
What can Lagrange see in my Google Drive?
Only the files you pick in Google's picker and the files Lagrange created there for you. It cannot browse the rest of your Drive. See the privacy policy.
How do I disconnect Google Drive?
In Lagrange: Settings › Cloud connections › Google Drive › Sign out. You can also remove access in your Google Account at myaccount.google.com/connections.
I forgot how to open Private.
Private opens with Face ID, Touch ID or your code, or with the recovery code you saved when you set it up. We cannot open it for you: the key never leaves your iPhone.
How do I back up my files?
Your iPhone's own backup includes Lagrange. A one-tap "Back up my library" inside Lagrange is planned.
I deleted something by mistake.
Look in the Recycle bin in Files, or use Undo right after the action. Deleted files stay in the bin for 30 days by default.
