Your data never leaves your device
There is no account and no server. Each tool saves what you type inside your own browser, and the trackers have buttons to download a backup or delete everything.
To keep the tools on your phone, use the "Install as an app" button at the top when your browser shows it, or open your browser menu and choose "Add to Home screen". After the first visit the tools open with no internet.
Clearing your browser data deletes what you saved, so download a backup now and then.
Tell me what broke or which tool you want next: @makishima1984 on X.
I also make short animated videos on the moments everyone remembers: games, sport, anime, history and news.
