Privacy policy

Last updated 6 October 2026

The short version: there are no accounts, and your library never leaves your device unless you choose to export it. The longer version follows.

What is stored on your device

Conquest of Pages keeps your data in your browser's local storage: the books you add, your ratings, notes, tags and reading log, your goals and reading sessions, the species you have discovered, your achievements, and your theme and display choices. It also keeps a small cache of the app's own files so it loads quickly and works offline. None of this is sent to us — we run no server that receives it. Clearing your browser data erases it, which is why Settings offers a backup file.

What leaves your device

To do its job, the app asks a few public services for information. They receive the request itself, and — as with any website you visit — your IP address and browser details:

• Open Library (openlibrary.org, run by the Internet Archive): the text you type in the book search, author names (to find where an author is from), and book cover images.
• Wikidata and Wikipedia (Wikimedia Foundation): an author's name, to look up their birthplace; a tree, flower or river's name, to show a photo and summary.
• Open-Meteo geocoding (open-meteo.com): a place name you type when choosing a location by hand.

The globe's geographic data, fonts and images are served by this site itself, not by a third party. Each of the services above has its own privacy policy and is not controlled by us.

Advertising

This site does not currently show advertising.

Analytics

This site uses Umami analytics (no cookies, no personal data) to count visits in aggregate. It does not build a profile of you.

Your choices

• Export: download a backup or a spreadsheet from Settings at any time.
• Delete: “Delete all my data” in Settings removes your library from the browser; clearing the site's data in your browser settings removes everything, including the app cache.
• Offline cache: remove it by clearing site data, or uninstall the app if you installed it.

Children

Conquest of Pages is a general-audience reading tool and is not directed at children under 13. We do not knowingly collect personal information from anyone.

Changes

If this policy changes, the date above changes with it.
