Privacy Policy

Last updated: October 11, 2026

This Privacy Policy describes how Zef Labs (“we,” “us,” or “our”) handles information in connection with our website and applications (collectively, the “Services”).

Information We Collect

Our website does not collect personal data. Our games do not ask for your name, email, phone number, contacts, photos or precise location, and you never create an account.

To keep our games, Dogudoku, Shoo and Hoopsy, working well and to understand how they are played, each collects a small amount of information. It is tied to an anonymous ID created on your device, never to your name, email or an account:

• An anonymous install ID. A random identifier created when you first open the game. It is not your name, your email or your device’s advertising ID.
• Gameplay events. For example, when a level is started, finished or failed, how long it took, how many mistakes or misses were made, which boosters were used, and which settings were changed.
• Diagnostics. Errors that occur in the game, and how long the game takes to start.
• Approximate location. The country you are in, which our analytics providers work out from your IP address. We never use GPS or precise location.
• Device information. Such as the device model and operating system version, as reported by our analytics providers.
• Install attribution (Dogudoku only). Whether one of our ad campaigns led to the install, and which; when the game is installed and opened; and a few milestones, such as finishing the tutorial or winning a level. It is tied to an ID for the app on your device (on iPhone, the app vendor ID), never to your device’s advertising ID.

The games save your progress, settings and boosters on your device, and do not send them to us.

How We Use Information

We use this information to fix problems, to improve the games (for example, to see which levels are too hard), and to show you how your results compare with other players’. We combine each level’s results from all players into totals, such as how many players solved it and how long they took; these totals contain no personal data.

We use the install attribution information to learn which of our own ad campaigns bring players to Dogudoku, so we can spend on the ones that work. The ad networks we advertise on receive only aggregate results from it, never information about you.

We do not sell this information, we do not show ads in our games, and we do not track you across other companies’ apps or websites.

Third-Party Services

Dogudoku, Shoo and Hoopsy use these services, which process the information above on our behalf.

• Google Firebase (Analytics, Authentication and Cloud Firestore), for the anonymous install ID, analytics, and the level results. Google’s privacy policy
• GameAnalytics, for gameplay analytics. GameAnalytics’ privacy notice
• AppsFlyer (Dogudoku only), for install attribution. AppsFlyer’s privacy policy

We do not sell or rent personal data. Our website is hosted on a third-party platform that may collect standard, non-identifying technical logs (such as IP addresses) as part of normal operation; we do not control or use this information for our own purposes.

Your Choices

Because we never collect your name or email, we cannot look the information up by them. Deleting the game removes everything saved on your device and ends the collection. If you have a question or a request about your data, contact us at hello@zeflabs.co.

Children’s Privacy

Our Services are not directed to children under the age of 13, and we do not knowingly collect personal data from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date.
