Local first. Your tasks, notes and drawings live in a database on your own device. Signing in does not, by itself, upload your day.
If you don't sign in, nothing leaves your machine. No analytics ping, no ad SDK, no third-party tracker in the app.
If you sign in, we use Firebase (Google) for authentication and a small amount of account data: your email, your chosen handle, your plan tier, and the minimum needed for shared timelines with people you invited. If you switch cloud sync on, task data is stored under your account and shared with nobody unless you share it yourself.
If you subscribe, payments are handled by Dodo Payments. We never see or store your card number. We receive confirmation of your tier, nothing more.
What we don't do. We don't sell data, run ads, or train anything on your writing without an explicit, revocable opt-in.
Desktop awareness. The companion reads the title of your foreground window to decide whether to stay quiet. It is read, used once, and discarded — never stored, never transmitted. It can be switched off in settings.
Your rights. Export everything from inside the app at any time. Email hello@fuidzy.com to delete your account and associated data. Local data is gone the moment you delete it — we never had a copy.
