Tell us four things

It saves a round trip if the first message includes them.

Things that go wrong most often

I paid, and Premium is still closed

Open the account page and use Restore purchases. Premium opens only after Apple confirms the transaction and our server verifies it, so a moment of network trouble can leave the two out of step. If restoring does not fix it, write to us with the date of purchase.

My library is empty

The library only shows books that are published in your chosen book language. Change the book language in the account page, or use the temporary language filter in the library to see what exists elsewhere. An empty library, a failed load and a permission problem are shown as three different states on purpose, so tell us which one you saw.

I want to cancel Premium

Cancel it in your Apple account settings, under Subscriptions. We cannot cancel it for you, because Apple holds the billing relationship. Cancelling stops the next renewal and leaves your access running to the end of the period you paid for.

I want a refund

Refunds go through Apple, at reportaproblem.apple.com. When Apple tells us a purchase was refunded, Premium access ends.

I want my account deleted

Write to us from the address on the account. Cancel the Apple subscription first, because deleting the account does not stop Apple billing. See the privacy policy for what is removed.

A summary looks wrong

Tell us the book, the part, and the sentence. Fidelity is checked by an automated gate before publication, and a report that gets past it is worth more to us than a feature request.

Not yet available

Android, iPad layouts, a web reader, audio narration and downloads for long term offline reading are not in the first version. Asking for them is useful. It is how the order gets decided.
