Lanterne helps ride groups plan rides and keep the memories. We store only what’s needed for that, we never sell your data and we show no ads.
Who we are
Lanterne is run by Tobias Demuth, Denmark, who is responsible for your data (the data controller).
What we store
Your account: your email address, and your name if you sign in with Google or type it in.
Your profile, if you fill it in: last name, home area, one line about you and a photo (uploaded by you, or your Google photo if you choose it).
What you add: your answers to groups (I’m in, Maybe, Not this time), the tasks you take or add, your season (chapters, dates, notes, sign-up links) and the names you add to an invite list.
Feedback you send us, and whether we may contact you about it.
Usage counts: for example that the app was opened, an invite link was opened or a chapter was added. We use them to see what works, never for advertising.
Who can see what
People in your groups see your first name, your answers and your tasks, the chapters in your season, and your profile and photo. Your last name only shows as an initial, and only when two in a group share a first name.
Anyone with a group’s invite link sees the first names and answers on that invite, so they can find their own name. Treat the link like a private group-chat link.
Nothing you add is public or shown to search engines. The founder can see accounts for support and to keep the app running.
Where your data is
Our database runs at Supabase through Lovable Cloud, in the EU (Ireland). Sign-in emails are sent by that same service. If you choose “Continue with Google”, Google tells us your name and email address.
On your device
We keep only what the app needs: that you’re signed in, your language, and anything you started before signing in (an answer or your season). No advertising or tracking cookies, and the fonts come from our own app.
Why we may use it
To give you the service you signed up for (your account, groups and season), and our legitimate interest in improving Lanterne with usage counts and feedback. We contact you about feedback only if you ticked the box.
How long we keep it
As long as you have an account. When you delete it, your account, profile, photo, answers, season and memberships are removed. Groups and chapters you created stay for the others, without your name, and feedback you sent stays without a link to you.
Your rights
You can see, correct and delete your data, get a copy of it, and object to how we use it. Delete your account yourself under Account → Delete my account; for anything else, contact us. You can also complain to the Danish Data Protection Agency (Datatilsynet).
Contact: use the Feedback link at the bottom of any page.
