Math Ninjas ("the App") is a math practice game designed for children. This Privacy Policy explains what information is collected when you use the App and how it is used. We take children's privacy seriously and have designed the App to collect as little information as possible.
The App itself does not require you to create an account, log in, or enter any personal information (such as your name, email address, or location) to play.
The App saves your gameplay progress directly on your device, including your score, level, unlocked achievements, daily streak, practice statistics for each math operation, and your sound and practice preferences. This information stays on your device — it is never collected by us, transmitted to our servers, or shared with anyone. You can permanently erase all of this saved progress at any time using the "Start Fresh" option inside the App's Progress Reports section.
The App displays advertisements through Google AdMob. To serve ads, AdMob may automatically collect limited technical information from your device, such as:
Device identifiers (used only for ad delivery and fraud prevention)
General technical data (device type, operating system version, app version)
Ad interaction data (such as whether an ad was shown or clicked)
This information is collected and processed by Google, not by us directly. We do not have access to, and do not collect, any personally identifiable information about our users.
This App is directed at children. In compliance with the Children's Online Privacy Protection Act (COPPA) and Google Play's Families Policy:
All ads shown in this App are configured as child-directed and non-personalized.
We do not knowingly collect personal information from children.
We do not use behavioral advertising or targeted ads based on user profiles.
The App does not include social features, chat, or any way for children to communicate with strangers.
The App includes an optional "Progress Reports" section intended for parents, guardians, or other supervising adults. Access requires correctly solving a simple math problem first (a "parental gate"), so that young children are unlikely to enter it by accident. This section only displays gameplay statistics already stored on the device — it does not collect any new information.
This App uses Google AdMob to display advertisements. Google's use of information is governed by Google's own Privacy Policy, which you can read here:
https://policies.google.com/privacy

Since we do not collect personal information directly, there is no personal account data stored by us on any server. Gameplay progress is stored only on your own device and is subject to your device's own security. Any technical data collected via AdMob is handled according to Google's security practices.
If you are a parent or guardian and believe your child has provided personal information through this App in a way that concerns you, please contact us using the information below and we will look into it promptly.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date above.
