Using the library
The library list is open to everyone, but the stories are only for Reitaku students and staff: to read them, sign in with a Reitaku Google account. The site also stores a random identifier in your browser and records which stories are opened, reading times, words looked up, words searched in the dictionary, answers to the question comparing story difficulty, and audio listening time. These anonymous records are used to improve the reading library, for example to see which words need a Japanese meaning, which words the dictionary is missing, and whether stories are at the right level.
Accounts
If you choose Continue with Google, Google provides your name, email address and a unique account identifier for authentication. Extensive Reader stores the stories you mark as read, completed reading dates, word counts, reading time, lookup counts, the words you look up and the sentences they appear in, the words you search in the dictionary, the words you save to learn, audio use, and the paragraph and audio positions you choose to bookmark. You can see the words you have looked up in My words. Progress saved on this device before sign-in may be added to your account when you sign in. This information can then be synchronized across your devices. Your Google password is never provided to Extensive Reader. The same account is shared with the vocabulary flashcard app run by the same teacher, so one Google sign-in works for both.
How data is used
Information is used to provide synchronized reading progress, operate the site, and understand how the library is used. If you enter a class code, you join that class on both this site and the flashcard app. Your class teacher and the site owner can view your name, email address and class, and your per-account completed reading activity, including reading days, stories, word counts, the words looked up, dictionary searches, and listening time, in a private dashboard. The site owner can also view accounts that are not in a class and can change an account's class. This is not visible to other readers. Information is not sold or used for advertising. Apart from dictionary searches made while signed in, anonymous reading-activity records are not intentionally linked to your Google account.
Service providers
Google provides sign-in, Supabase provides authentication and database services, and Cloudflare hosts the website. These providers process information as needed to provide their services and apply their own privacy and security practices.
Your choices and questions
You may sign out at any time. To ask about your information or request deletion of your account and synchronized progress, email ciaranrawlinson@gmail.com.
