Something not working, a book you cannot find, a question about Pro? Write to us here or at support@innowavesolution.com. A person reads every message, usually within two working days.
Say whether you are on iPhone or Android, and the app version from Profile if it is about a bug.
Quick answers
I paid for Pro on another phone, or after reinstalling
Open Profile and tap Restore purchases. The subscription is tied to your Apple ID or Google account, not the install.
How do I cancel the subscription?
On iPhone: Settings → your name → Subscriptions. On Android: Play Store → your profile → Payments and subscriptions → Subscriptions. Cancelling keeps Pro until the end of the period you paid for.
A book is not in the search
Try the ISBN from the back cover, or scan the barcode. If no catalogue has it, use Add it myself under the results and it stands on the shelf like any other.
Reminders do not arrive
Check that notifications are allowed for BookZEN in your phone's settings, then set the time again in Profile → Reading reminders.
How do I delete my data?
Everything is on your phone: deleting the app deletes it. For anything held by our services, see the privacy policy and write to us.
