Short version: Starcredits does not collect, store, transmit, or share any personal data. Everything stays on your device.
1. What is Starcredits?
Starcredits is a Chrome extension that allows users to capture frames from YouTube videos, add timestamps, watermarks, and channel credits, and save or copy the resulting image. It is designed for journalists, space enthusiasts, and content creators who document live streams.
2. Data We Do NOT Collect
Starcredits does not collect, transmit, sell, or share any of the following:
Personal information (name, email, location, etc.)
Browsing history or activity
Video content or screenshots
YouTube account information
Usage analytics or telemetry
Any data from pages visited outside YouTube
3. How the Extension Works
All processing happens locally in your browser:
Frame capture: When you trigger a capture, the extension reads the current video frame directly from the YouTube player. This data never leaves your device.
Image processing: Watermarks, timestamps, and crops are applied using an offscreen Canvas API inside the extension. No external servers are involved.
Saving: Images are saved directly to your computer via the browser's standard download API, or copied to your clipboard. No upload occurs.
Settings: Your preferences (watermark position, timestamp corner, etc.) are stored in chrome.storage.sync, which is local to your browser and optionally synced by Chrome across your own devices if you have Chrome Sync enabled. Starcredits does not have access to this sync data.
4. Permissions Explained
The extension requests the following Chrome permissions, each with a specific technical reason:
activeTab / scripting: Required to access the YouTube video player and capture the current frame when you click the extension button or press the keyboard shortcut.
storage: Used to save your preferences (e.g. watermark settings, timestamp position) locally in your browser. No data is sent externally.
offscreen: Required by Chrome Manifest V3 to render images (apply watermarks, crop, and compose the final PNG) in a background context without a visible tab.
downloads: Required to trigger the "Save PNG" file download dialog.
clipboardWrite: Required to copy the final image to your clipboard when you click the "Copy" button.
contextMenus + <all_urls>: Used to add an optional "Open image in Starcredits" entry to the right-click menu on images across all websites. This feature is enabled by default but can be turned off in the extension's Options page. No content scripts are injected on non-YouTube pages. No data from other websites is read or stored.
5. Third-Party Services
Starcredits does not integrate with, communicate with, or send data to any third-party service, analytics platform, or remote server of any kind.
6. Children's Privacy
Starcredits does not knowingly collect any information from anyone, including children under the age of 13.
