Readpin Privacy Policy
Effective date: July 3, 2026
Readpin is a reading app that lets you pin books to the places you read them. This policy explains what information Readpin collects, how it's used, and the choices you have. We've tried to keep it short and in plain English, because our data practices are simple: we collect what the app needs to work, we don't sell your data, and we don't show you ads.

What we collect
Account information. When you sign up (with Apple, Google, or email), we store your email address, username, display name, and — if you add them — a bio and profile photo. Apple and Google sign-in share your name and email with us as part of signing in; if you use Sign in with Apple's private relay, we only see the relay address Apple provides.
Your content. The heart of Readpin is what you create: book pins (the book's title and author, the pin's location, an optional note, an optional photo, and the date), your shelf (which books you've read, are reading, or want to read), your genre preferences, and any recommendations you share. If you import your reading history from Goodreads or StoryGraph, the file is read on your device and we store the books from it.
Location. Readpin uses your device's location (with your permission) in three situations, all in the foreground while you're using the app: when you open the map, to center it on where you are; when you drop a pin, to suggest your current location; and when you set up a privacy zone in Settings. Readpin never tracks your location in the background. When the app turns coordinates into a readable address, that lookup is handled by your device's built-in (Apple) geocoding service. You can always type or edit a location manually, and location permission can be revoked at any time in iOS Settings — the map and pins still work without it.
Friends. If you connect with friends, we store those connections so the app can show you each other's shared pins.
Subscription status. If you subscribe to Readpin Premium, our payments partner RevenueCat manages your subscription status. RevenueCat receives a pseudonymous account identifier (your internal Readpin account ID — not your name or email) and the purchase receipt from Apple. Payment itself is processed entirely by Apple — we never see or store your payment card details.
Crash and error data. If the app crashes or hits an error, we receive a technical report through Sentry (device model, OS version, app version, and the technical details of the error). These reports are configured to exclude personal information and are not linked to your account.
What we don't collect
- We don't sell your data. To anyone, ever.
- We don't show ads and don't share your data with advertisers.
- We don't track you across other apps or websites.
- We don't use product analytics or behavioral tracking SDKs, and we've disabled our map provider's optional telemetry.
- We don't collect your location in the background.
- We don't read your contacts or messages, and we can only access the specific photos you choose to attach.
How we use your information
We use your information for one purpose: making Readpin work. That means storing and displaying your pins and shelf, showing your shared content to the friends you've connected with, operating your subscription, keeping the service secure, and fixing crashes and bugs.
Who can see your content
You control visibility. Each pin has a visibility setting, and you can set your default in Settings. Pins you share are visible to your accepted friends; private pins are visible only to you. Precise pin locations are protected on our servers so that only the people your settings allow can access them.
Services we rely on
Readpin runs on a small set of infrastructure providers, each receiving only what's needed for its job:
- Supabase — hosts our database and file storage (your account data, pins, and photos live here).
- Mapbox — renders the map, generates the small map images shown on pins in the feed, and powers location search. When you search for a place, your search text (and your approximate location, to rank nearby results) is sent to Mapbox. We have disabled Mapbox's optional usage telemetry.
- RevenueCat — manages subscription status, as described above.
- Sentry — receives crash and error reports, configured to exclude personal information.
- Open Library, Google Books, and The New York Times Books API — we use these to fetch book covers, descriptions, and bestseller lists. Your book searches are sent to Open Library, and cover lookups may send a book's title or ISBN to Google Books. Bestseller lists are fetched by our servers, not your device. No account information is shared with any of them.
- Bookshop.org — "Buy this book" links open Bookshop in your browser. The link carries only the book's ISBN or title. Once you leave Readpin, Bookshop's own privacy policy applies.
We don't have "data partners" beyond this list, and none of these providers is permitted to use your data for their own advertising.
Data retention and deletion
Your data is kept for as long as you have an account. You can delete your account at any time in Settings → Delete Account inside the app. Deletion is real: it permanently removes your account, pins, photos, shelf, and social connections from our systems, including file storage. Crash reports in Sentry (which aren't linked to your identity) age out automatically under Sentry's retention period.
You can also email support@readpin.org to request deletion or a copy of your data.
Security
Your connection to Readpin is encrypted in transit (TLS). Data access on our servers is enforced with row-level security so accounts can only read what their permissions allow, and your login session is stored encrypted on your device.
Children
Readpin is not directed at children under 13, and we don't knowingly collect information from anyone under 13. If you believe a child under 13 has created an account, contact us at support@readpin.org and we'll delete it.
Changes to this policy
If we make material changes, we'll update this page and the effective date above. Continued use of Readpin after a change means you accept the updated policy.
