Privacy Policy for Vivum
Last updated: 27 October 2026
Vivum is a daily check-in app. To do its job it has to know when you last checked in and who to tell if you stop. This policy explains what we store, why, and what we never do.
Who is responsible
Vivum is developed by Stefan Crafoord-Wiklund, who is the data controller. Contact: vivum@crawik.com.
What we store about you
- Account: a user ID and email address from Sign in with Apple (this may be an Apple private relay address), and the name you give for alerts.
- Check-ins: the time of each check-in and how you made it (app, widget, notification or Siri).
- Settings: your time zone, language, check-in interval, reminder time, pause dates and the optional note you write for your contacts.
- Device token: so we can send you warning notifications.
What we store about your contacts
The name, email address and preferred language you enter for each contact, whether they have confirmed, and delivery records for emails we send them. We email a contact only after they confirm by clicking a link in an invitation. Every email has an unsubscribe link.
Why we use it
Only to run the check-in service: to remind you, to warn you before your deadline, and to email your confirmed contacts if you miss it. The legal basis is our agreement with you (the service you asked for) and, for contacts, their consent.
What we never do
- We never sell or share your check-in data. When you check in reveals when you’re home and alone, so it stays with us.
- No advertising and no ad tracking.
- No tracking across other apps or websites.
Who processes data for us
- Our own servers in the EU store the account and check-in data.
- Resend (EU region) sends our emails.
- Apple delivers push notifications and handles Sign in with Apple and payment.
- TelemetryDeck receives anonymous usage statistics with no names, emails, notes or check-in times. You can turn this off in Settings.
- Healthchecks.io monitors that our alert service is running. If a run fails, the error report it receives may include a random account ID, but never names, emails or check-in times.
How long we keep it
For as long as you have an account. When you delete your account in the app, your check-ins, contacts, settings and device tokens are deleted from our servers. Server backups are kept for up to 14 days and then overwritten.
Your rights
You can see and change your data in the app, and delete it with Delete account. You can also ask us for a copy, a correction or deletion, or object to our use of it, by email. If you’re unhappy with how we handle your data, you can complain to your data protection authority (in Sweden, IMY).
Not an emergency service
Vivum doesn’t contact emergency services and can’t guarantee when an email or notification arrives. In an emergency, call 112.
