Welcome to Stream Danmaku. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our browser extension and associated services.
We collect minimal information necessary to provide you with the Stream Danmaku service. When you log in using your Google account via OAuth, we receive your basic profile information such as your Google ID, email address, name, and profile picture.
We do not collect or store your Netflix viewing history, passwords, or unrelated browsing activity. The extension only reads the current video ID on supported streaming platforms to synchronize danmaku comments.
The information we collect is used in the following ways:
We do not sell, rent, or trade your personal information to any third parties for marketing or advertising purposes.
Your authentication tokens and personal preferences are stored locally on your device within the browser extension's secure, isolated storage environment. Danmaku comments you post are stored on our servers and associated with your unique account identifier.
Our extension interacts with third-party streaming platforms like Netflix to display comments on top of their video players. We do not transmit your personal data from Stream Danmaku to these platforms.
You have the right to access the personal information we hold about you and to ask that it be corrected, updated, or deleted. You can revoke our application's access to your Google account at any time through your Google Account Permissions settings.
We may update this Privacy Policy from time to time to reflect changes to our practices or for other operational, legal, or regulatory reasons. We will notify you of any material changes by posting the new policy on this page.
If you have any questions or concerns about our privacy practices, please contact us through the official support channels listed in the extension dashboard.
