This is the support page for the Recipes Book app (called Oshxona in Central Asia; developer: Abdufattokh Malikov).

Email: malikov.creates@gmail.com. Tell us what happened and, if you can, attach a screenshot. From the app it is easier: Profile → Support opens an email with your support ID already in it.

Payment, the free trial, renewal and refunds are handled by the App Store and Google Play. You can cancel at any time: on iPhone, Settings → your name → Subscriptions; on Android, Google Play → your profile icon → Payments & subscriptions → Subscriptions.
