iTAPEK Pro is an iPhone application developed by TAPEK s.r.o. that combines an electronic book with an extensive database of comments and references. The app aims to provide detailed, organized, and up-to-date notes on selected Czech tax laws.

This paid (Pro) version offers access to the text of the laws and all the accompanying commentary for the duration of the subscription, which is offered for six months. The subscription automatically renews unless the option for automatic renewal is turned off at least 24 hours before the end of the subscription period.

Payment for the subscription will be charged to the user's iTunes Account 24 hours prior to the end of the current period, and the cost of the renewal will be specified. Users have the option to manage their subscriptions and turn off auto-renewal in the Account Settings after purchase.
