What Tempo is
Tempo is a personal calendar app operated by Zulkernain Tasin in Vilnius, Lithuania. It shows events from calendars you connect, together with routine blocks you define, and computes your free time. It is built for its owner and a small number of people who choose to use it.
What is stored
- Your account: email address, name if you give one, a password hash if you sign in with a password, your timezone and free-time settings.
- Calendar connections: for Google, the email of the connected account and the OAuth refresh and access tokens Google issues; for iCloud, your Apple ID and the app-specific password you enter; for subscriptions, the link. Tokens and passwords are encrypted at rest with a key that is not stored in the database.
- Calendar data: the list of calendars on each connection, and for enabled calendars the events in a window from 30 days ago to 180 days ahead: title, description, location, times, status.
- Routine blocks and events you create in Tempo.
How Google user data is used
Tempo requests the Google Calendar scopes to read your calendars and to create, edit and delete events when you ask it to. Calendar data is used only to show your schedule, compute free time, and write back changes you make in Tempo. It is stored in Tempo's own database so the app can show it quickly and compute free time across accounts.
Google user data is never sold, never used for advertising, never used to train models, and never shared with anyone other than the account owner. Tempo's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Who can see it
Only you, signed in to your account. The operator has technical access to the database for maintenance and does not read calendar contents. If you create a sharing link under Find time, the page at that link shows only free time ranges for the next seven days, never event titles, and you can rotate the link at any time.
Where it lives
The app runs on Vercel and the database on Neon, both in the European Union region. Connections to Google and Apple use HTTPS. No analytics or advertising scripts run in the app.
Deleting your data
Removing a connected account under Accounts deletes its tokens, calendars and events from Tempo immediately and stops Google push notifications for it. You can also revoke Tempo's access at myaccount.google.com under Third-party access. To delete your whole account and everything in it, email the address below; it is done within 7 days.
