Privacy policy
Updated 5 November 2026
Täna is made by Nuhvel Solutions OÜ (registry code 14747961), a small company in Viljandi, Estonia. We're responsible for the data described here. If something on this page is unclear, write to tana@nuhvel.solutions and a person will answer.
What Täna keeps
- Your tasks, goals and settings, and how you answered the morning question. Täna plans your days from these, so it can't do without them.
- Your account, if you make one: the email address you sign in with, or your Google account.
Without an account all of this stays on your device, or in your browser on the web, and none of it is sent anywhere; if you lose the device, delete Täna, or clear the browser's data, it's gone with it. With an account, they're kept in Google Firebase, which runs accounts and storage for Täna. That's how the same tasks show up on your phone and your laptop.
What stays on your device
- Your calendar. With “Use my calendar” on, Täna works out how much of each day your events take up, and it does that on your device. The events themselves aren't saved or sent anywhere. Täna knows your Tuesday is busy, not what it's busy with. On the web, your browser fetches the calendars from Google, and Google's permission runs out after an hour.
- Reminders. Your device schedules them itself, so they don't come from a server.
Crash reports
When one of the Apple apps crashes, it sends a report through Firebase Crashlytics so we can find what broke. The report describes the device and the crash. Your tasks aren't in it.
What Täna doesn't do
No ads, and your data isn't for sale. Täna doesn't follow you around the web either. A to-do app has no business knowing where else you go online.
Deleting your data
Settings has “Delete account”, or “Delete everything” if you never made one. It deletes your tasks, goals and account all at once. There's no undo, so be sure.
