Ambio Reader — Support

Last updated · September 22, 2026

Ambio Reader is made by one person. If something doesn't work, or you have a question, write to me at support@ambio.cloud. I read every message and usually reply within two working days.

It helps if you include your device model and — for a book problem — the book's title.

Subscriptions

Ambio Reader is a subscription, monthly or yearly. Payments, renewals and cancellations are handled by the App Store or Google Play, not by me.

  • Manage or cancel — in the app, go to Settings → Manage Subscription. You can also cancel on iPhone and iPad or in Google Play. Cancel at least 24 hours before the renewal date to avoid the next charge.
  • Restore a purchase — on a new phone, or after reinstalling, sign in with the same account and tap Restore Purchases in Settings or on the subscription screen.
  • Refunds — refunds are decided by the store you paid through: Apple or Google Play. If you are unhappy for any reason, write to me as well.
  • Deleting your account does not cancel your subscription. Cancel it in the store first.

How much can I analyze?

A subscription includes up to 15,000 pages per billing month, so it does not matter whether you read a few long novels or many short books. A page is 1,800 characters of text, about one printed page. A book counts once, when it is first analyzed; opening it again, re-reading it, or reinstalling the app does not count again. The allowance renews with each billing month.

Importing books

  • Tap Import Book in your library and pick a file. EPUB, MOBI, AZW and AZW3 files are supported.
  • Books must be free of DRM. Books bought in most stores are locked to that store's reader and can't be opened by other apps.
  • Please only import books you own or that are in the public domain.
  • The first time you open a book, it needs an internet connection so its scenes can be analyzed and its sounds downloaded. After that it works offline.

Something isn't working

  • No sound — check the volume and, on iPhone, the silent switch; then open the sound settings in the reader and make sure sound is on.
  • A book won't import or analysis fails — try again on a stable connection. If it keeps failing, email me the title and I'll look into it.
  • A sound doesn't fit the scene — tell me the book and chapter. Those reports are exactly what improves the matching.

Your account and data

You can delete your account in the app under Settings → Delete Account. See Account & data deletion for what is removed, and the Privacy Policy for how your data is handled.
