PRIVACY
This extension does not have an account and does not send data to the developer. When you run a check, it reads the book title, author, and ISBN from the StoryGraph page you are viewing, opens Amazon in a background tab to look that book up, and closes that tab when the check finishes. The last finished result for a book stays on your device for 24 hours. Uninstalling the extension removes stored data.
This project is not affiliated with, endorsed by, or sponsored by StoryGraph or Amazon.
PERMISSIONS

• Alarms — ends a check if Amazon does not respond so the page does not wait forever
• StoryGraph — needed to show the check control and read the book you are looking at
• Amazon — needed to look up that book and see whether Kindle Unlimited is offered
