DanmuMaker (Bullet Screen) Privacy Policy

Last updated: February 4, 2026

Summary

Thank you for using DanmuMaker (Bullet Screen). This is a locally running bullet-screen (danmu) display tool. Its main purpose is to let you enter text on your device and show it full screen as danmu.

Most important: DanmuMaker does not collect, store, or upload any of your personal information, and does not perform any form of network tracking or advertising analytics.

1. What information do we collect?

While you use DanmuMaker:

The danmu text you enter and the font, color, background color, and other options you choose are used only in local memory for immediate display;
The app does not upload this content to any server;
The app does not access your contacts, photos, location, microphone, or other sensitive permissions.

We do not actively collect any personally identifiable information.

2. How is information used?

All data generated in DanmuMaker is used only for the following purposes:

To render and display danmu effects in real time on the current device;
To adjust the display based on your settings (such as font, color, and scrolling style).

This data is not used for advertising, user profiling, or any commercial analytics.

3. Is information shared with others?

No. DanmuMaker:

Does not integrate any third-party analytics, advertising, or SDKs;
Does not share, sell, or rent any of your information to any third party.

4. Data storage and security

DanmuMaker does not currently save your danmu content on the device for the long term. Data mainly exists in runtime memory and is released automatically when you close the app.

Because there is no server-side storage or network transmission, your content is not sent over the network and is not stored in the cloud.

5. Protection of minors

DanmuMaker is not marketed to any specific age group and does not actively collect any information from minors. If you are a guardian and have questions about a minor’s use of this app, please contact us.

6. Updates to this policy

As features evolve, if DanmuMaker’s data-handling practices change, we will update this privacy policy on this page and note it in the version update notes.
