Zendoku does not collect any data about you. The app makes no network requests of its own, has no accounts, no ads, no analytics, and no third-party code.
Your progress, settings, and puzzle history are saved on your iPhone only. We cannot see them. Deleting the app deletes them.
The free trial and the one-time unlock are handled by Apple through the App Store. Apple processes your payment and tells the app only whether you own the unlock. We never receive your name, email, or payment details. Apple's handling of your information is covered by Apple's Privacy Policy.
Zendoku is suitable for all ages and collects no data from anyone, including children.
This website is separate from the app. If you contact us through the site, we use what you send only to reply to you. The website's own practices are described in the Fun Side LLC Privacy Policy.
If a future version of Zendoku changes any of this, we will update this page and the date above before that version is released.
