Theoria is made by Theoria Studios Inc. in Vancouver. A person reads every message.
Write to us
support@readtheoria.com. Write from the address on your account so we can find it. We answer within two business days, usually the same day.
Signing in
There is no password. Enter your email and we send a one-time code. One account covers everything — the website, and the app on any phone or tablet you sign in on. Your reading position, highlights and notes follow you between them.
If the code does not arrive, check the spam folder, then try again in a minute. If it still does not arrive, write to us with the address you used.
Subscriptions and billing
Whoever took the payment is the only one who can change it, so where you subscribed decides where you manage it.
- Bought in the app on an iPhone or iPad: Apple bills you. Change or cancel under Settings → your name → Subscriptions, or in the App Store app. Refunds are issued by Apple at reportaproblem.apple.com.
- Bought in the app on an Android device: Google bills you. Change or cancel in the Play Store app under Payments and subscriptions → Subscriptions, or at play.google.com/store/account/subscriptions. Refunds are requested through your Google Play order history.
- Bought on readtheoria.com: open Account to change your plan, update a card, or cancel. Cancelling keeps your membership until the end of the period you have paid for.
A membership bought in one place works everywhere you sign in — a subscription bought on an iPhone still opens the whole library on the web and on an Android tablet. Your Account screen names the store that is billing you. If a membership you have paid for is not showing, tap “Restore purchases” on the app’s Account screen, or write to us.
Deleting your account
In the app, open Account and choose “Delete account”. Deletion is permanent: your highlights, notes, reading history and research conversations are removed.
A subscription billed by Apple or Google is not cancelled by deleting your account — cancel it in that store first, or you will keep being charged. A subscription bought on the website is cancelled for you.
From the website, write to support@readtheoria.com from the address on your account and we will delete it and confirm by email.
A problem in a text
A missing footnote, a broken paragraph, a wrong attribution — tell us the work, the chapter, and a few words of the passage, and we will fix the edition. Corrections reach every reader, on every device.
