Grimoire Privacy Policy
Last updated September 30, 2026
Grimoire is published by Playsthetic LLC. It has no analytics, advertising or crash reporting, and it never uploads your files. This page describes what Grimoire keeps and everything it sends off your device. Our Privacy Policy covers the rest, including buying a license, how long we keep what reaches us, your rights, and how to contact us.
On your device
Your library index and covers stay on your device.
In your folders
Grimoire keeps a hidden .grimoire folder inside your library folder, holding your reading progress, favorites, pins and their notes, your collections, and the full path of every folder in the library. The folder travels with yours, so anyone you sync or share it with can read it. Metadata you edit is written into the comic files themselves, and Keep Organized, when you turn it on, moves books into author and series folders.
What leaves your device
Series details
The first time you open a series, Grimoire sends its name to Wikipedia and Wikidata to fill in the summary, authors and genres your files leave out, and keeps the answer on your device for 30 days. The name is the only part of your library that is sent. Turn off "Look up series on Wikipedia" in Settings to stop it.
Received by the Wikimedia Foundation.
Progress on iCloud
With Pro, turning on "Store progress on iCloud" keeps each series' bookmark (the file name and page), when you last read it and whether it is a favorite in your own iCloud account, so your other devices can pick up where you left off. Apple stores it, and we cannot see it.
Received by Apple.
Update checks
Copies downloaded from our website or installed with Homebrew check for a newer version by fetching a small file from s3.playsthetic.com. The request carries only what any web request carries, such as your IP address, and our server logs keep it for up to 7 days. Downloading an update is counted like any other download, as our Privacy Policy describes. A copy from the App Store leaves updates to the App Store instead.
Received by Playsthetic LLC.
License checks
When you enter a license key, Grimoire keeps it in your system keychain, which holds on to it even after you delete the application. It sends the key to api.playsthetic.com to confirm it is valid, then again at each launch. Besides the key, the request carries only what the application sends with any request, such as its version and your operating system version. We record the day the key was last checked. A copy from the App Store checks your purchase with Apple instead, and sends us nothing.
Received by Playsthetic LLC and Apple.
Deleting your data
What Grimoire keeps on your device or writes into your folders never reaches us, so you can delete it yourself at any time. A license key stays in your system keychain until you remove it with Keychain Access. To ask about anything that did reach us, see Your rights in our Privacy Policy.
