Where Does Tuta Store Local Data and Offline Mail?
Tuta desktop caches encrypted mail under tutanota-desktop folders on each OS. The folder kept its old name after the rebrand.
Last updated
Tuta encrypts everything, including the local cache. The desktop app stores offline mail and credentials under a folder still named tutanota-desktop on all three desktop systems. That name trips people who search for tuta and find nothing.
Secrets themselves sit in your OS keychain, not in these folders. Deleting the folder logs you out and drops the cache, which fixes most corrupt-cache issues. Server mail stays untouched.
Where Tuta stores this, by platform
%APPDATA%\tutanota-desktop
Holds cache, offline mail, and safe_storage keys metadata. Delete with the app closed to fix login and cache faults.
~/Library/Application Support/tutanota-desktop
Same contents as Windows. Remove via terminal if the app refuses to start, then reinstall is rarely needed.
~/.config/tutanota-desktop
AppImage, deb, and rpm builds share this path. Flatpak keeps its copy under ~/.var/app/com.tutanota.Tutanota/config instead.
/data/data/de.tutao.tutanota
Offline mail and credentials in the app sandbox. No stable path to type. Use in-app export and device transfer for migration.
/var/mobile/Containers/Data/Application/<guid>/ (Tuta container)
Per-install container. Same sandbox rules as other iOS mail apps. Migrate through the app, not the filesystem.
Frequently asked questions
How do I wipe the Tuta desktop cache?
Delete the tutanota-desktop folder for your OS while the app is closed, then log in again. That clears the offline cache and credentials without touching server mail.
Why is the folder still called tutanota-desktop?
The company renamed itself but kept the folder name for compatibility. Do not create a tuta-desktop folder by hand, the app will not read it.
Where is Tuta offline mail?
Turn on offline mail in settings and set how many days to keep. Cached mail then lives inside the same folders, encrypted with keys from your system keychain.
