Privacy policy

In short

ReadnMark is a chat and organising app for book clubs. We only collect what the app needs to work. We don't show ads, we don't sell your data, and we don't use analytics or tracking tools.

What we collect

Account: your email address. If you sign in with Google, the name and profile photo address Google shares with us. We never store a password.

Profile: your display name, an optional short line, your language.

Club content: clubs you create or join, your messages, photos you share in chat, emoji reactions, votes, poll answers and meeting replies (going / not going / maybe).

Reading: the page or percentage you enter for club books and when; books you add to your library.

Notifications: your notification settings and the push addresses of devices where you turned notifications on.

How we use it

Only to run the app: to sign you in, to show your messages and progress to your club, to apply spoiler protection, to send notifications and reminders, and to show your stats on your profile.

Who can see it

Club content (messages, votes, progress, meeting replies) is visible only to members of that club.

Your name and profile are visible only to people who share a club with you.

Your library is private by default. If you turn it on in Settings, your club friends can see it; they never see club names or your progress.

In anonymous polls nobody can see who picked what.

Services we use

Supabase: database and sign-in (data is stored in the United States).

Cloudflare R2: storing photos shared in chat (private storage; photos are shown only to club members, through short-lived links).

Our own server and Cloudflare: serving and protecting the site.

Brevo: sending sign-in emails.

Google: Sign in with Google.

Google Books and Open Library: when you search for a book, your search text is sent to them; who you are is not.

Apple, Google or Mozilla push services: to deliver notifications to your phone or browser.

Cookies and browser storage

We only use the session cookies that keep you signed in, and we store your theme choice (light / dark) in your browser. No advertising or tracking cookies.

Keeping and deleting

We keep your data while your account exists. You can delete your account any time in Settings → Delete my account: your profile, progress, library, votes and notifications are deleted. Messages you wrote in clubs stay so conversations still make sense, but they show “Former member” instead of your name. Clubs where you are the only member are deleted too.

Chat photos are shrunk on your phone before sending and their location (GPS) data is removed. Full size is kept for 90 days, after which only a small copy remains (except for pinned messages). Deleting a message deletes its photo too.

Your rights

To see, correct or delete your data, use the settings in the app or write to us.

Children

ReadnMark is not meant for children under 13.

Changes

If we change this policy we update the date on this page and announce important changes in the app.
