Privacy Policy

Last updated 14 November 2026

Earmark is a reading tracker. Your reading is yours: we don't show ads, we don't sell or share your data, and we don't track you across other apps or websites.

Without an account

You can use Earmark without signing in. Then everything you add, including your books, shelves, ratings, reviews, reading sessions and goals, is stored only on your iPhone. We never receive it.

With an account

Signing in is optional. If you do, we store the following so your reading can be backed up and synced between your devices:

This data is stored with Supabase, our database provider, and is only used to run Earmark. Each account can only read and change its own data. We use your email address only to send sign-in codes.

Looking up books

When you search, scan a barcode or open a book, Earmark sends the search words or the book's ISBN, title and author to public book catalogues to find covers and details: Open Library, Google Books, Apple Books and Wikidata. These requests don't include your name, email or account, but like any website, those services can see your device's IP address. Their own privacy policies apply.

Camera

Earmark uses the camera only to read the barcode on a book while you're scanning. No photos or video are saved or sent anywhere.

Importing

A Goodreads export you import is read on your iPhone. If you're signed in, the books from it are synced like any others.

Your choices

You can also email us to ask what we hold about you, to correct it or to delete it.

Children

Earmark isn't directed at children under 13, and we don't knowingly collect data from them.

Changes

If this policy changes, we'll update the date at the top of this page. If a change affects how your data is used, we'll tell you in the app first.
