What does the Octo app keep?

Lessons read and passed, quiz answers, reviews, practice exams, badges, your unit setting and Mega Quiz team names are stored only on your device. There is no account and no server: we receive none of this data.

Why does Octo ask for my age range?

The age range you choose the first time you open Octo stays on your iPhone. It is used to set up ads: ads suitable for all ages for everyone, and no consent request under 16.

How does advertising work in the free version?

Banner ads are provided by Google AdMob. Google’s SDK may collect technical data: IP address (for an approximate location), device identifiers, ad interactions and diagnostics. Ads are never personalized: Octo doesn’t ask for Apple’s tracking permission (ATT) and Google doesn’t target anything to you. In the European Union, your consent is asked before the SDK stores or reads information on your device; you can change it at any time in Settings › Ad Choices. See how Google uses data.

What about Octo Pro?

The purchase goes through Apple’s App Store; we never see any payment data. With Octo Pro, no ad is requested from Google.

What are your rights?

Since we hold no data about you, there is nothing to access or delete on our side. To erase your progress, use Settings › Reset Progress, or delete the app. For data processed by Google, see its privacy policy.

What does this website collect?

This website sets no cookies and runs no analytics, advertising or tracking scripts. It is hosted by Cloudflare, which processes technical data such as your IP address to deliver the pages and protect the site. The “Download on the App Store” badge is loaded from Apple’s servers.
