This Privacy Policy explains how 4BitStack (“we”, “us”, or “our”) handles information in our mobile games and applications (collectively, the “Apps”), including Arrowmetic. We built our Apps to respect your privacy: we collect only anonymous usage data to understand how the Apps are used and to improve them. We do not require an account, and we do not collect data that personally identifies you.
When you use an App, it may automatically send the following anonymous information to our analytics service:
| Data | Purpose |
|---|---|
| A randomly generated install identifier (UUID) | To count unique installs and how often the App is opened. It is not linked to your identity and resets if you reinstall or clear app data. |
| Device model and manufacturer | To understand which devices to support and optimize for. |
| Operating system version | To ensure compatibility across Android versions. |
| App version | To diagnose issues introduced in specific releases. |
| IP address | Automatically received by our server with each request; used only to derive approximate region and to protect against abuse. We do not use it to identify you and do not store a precise location. |
| In-app usage events | Anonymous events such as opening the App, starting or finishing a level or practice session, the level/result, in-game coin balance, and timestamps. Used to understand engagement and improve gameplay. |
We do not sell your data or share it with advertisers. The anonymous data is stored on our own servers hosted with a reputable cloud provider (Amazon Web Services). We may disclose information only if required by law or to protect our legal rights.
Anonymous usage data is retained only as long as needed for analytics and is aggregated over time. Because the data is anonymous, it cannot be traced back to an individual user.
Our Apps are suitable for general audiences. We do not knowingly collect any personal information from children. The data described above is anonymous and is not used to build user profiles or to target advertising. If you believe a child has provided us personal information, please contact us and we will address it.
Data is transmitted over encrypted connections (HTTPS) and stored on secured servers. While no method of transmission or storage is 100% secure, we take reasonable measures to protect the information we handle.
Our Apps are distributed through Google Play, which has its own privacy practices described in Google’s Privacy Policy. Our hosting provider processes data on our behalf solely to operate our analytics service.
Because we do not collect personal identifiers, there is no account to delete. You can reset the anonymous install identifier at any time by clearing the App’s data or uninstalling the App. You may also contact us with any privacy questions or requests.
We may update this Privacy Policy from time to time. We will revise the “Last updated” date above when we do. Continued use of the Apps after changes means you accept the updated policy.
