Spelli is a practice tool for spelling lists. Using it means you accept these terms.
Spelli reads out the words you type into it and marks what is typed back. It is a practice aid for a parent or teacher to use with a child, not a curriculum, and its marking follows the list exactly as it was typed. A typo in the list is marked as the list says.
Spelli Pro is a one-time in-app purchase sold and handled by Apple. It is not a subscription and never renews. It belongs to your Apple Account, and you can restore it from Settings in the app. Refunds are handled by Apple at reportaproblem.apple.com.
One list at a time, with no limit on the number of words, the system voice, unlimited tests and the score card, without time limits and without advertising.
Lists, scores, recordings and settings stay on your device, as the privacy policy describes. Deleting the app deletes them, and there is no copy to restore.
