Strictly necessary
One session cookie that says you are signed in. Without it there is no signing in, which is why it is always on and cannot be switched off.
The values security needs, such as the failed sign-in counter that stops somebody grinding at a password.
Preferences
Your language, the light or dark theme, which calendar you use, the tools you pinned and how you like lists displayed. These stay in your own browser's storage and are never sent to the server.
If you switch these off Flowra still works, but it opens with its defaults every time.
What we do not have
No advertising cookies, no third-party trackers and no behavioural profile. If anything of that kind is ever added, it will arrive under its own toggle, switched off, and will do nothing until you turn it on.
Changing your mind
