Privacy Policy
What data does FullSnap collect?
None. FullSnap does not collect, transmit, or store any personal data on external servers of any kind.
What happens when you take a screenshot?
When you use FullSnap to capture a page:
- The screenshot image is processed entirely within your browser using Chrome's built-in APIs.
- The image is stored temporarily in your browser's local IndexedDB storage so the viewer can display it.
- The image is automatically deleted from IndexedDB once you close the viewer tab.
- The image is never uploaded, transmitted, or shared with any third party — including the developer.
Settings storage
Your preferences (e.g. default format, JPEG quality, theme) are saved locally using chrome.storage.local — a browser-native storage API. This data stays on your device and is never synced to any server.
Network access
FullSnap makes zero outbound network requests. There are no analytics libraries, no crash reporters, no telemetry endpoints, and no external CDN dependencies. The extension is entirely self-contained.
Permissions explained
- activeTab — Required to access the currently active tab in order to capture it. Only activates when you explicitly click the extension button or use a keyboard shortcut.
- scripting — Required to inject a small content script into the page to scroll it and measure its dimensions during a full-page capture. The script does not read page content.
- offscreen — Required to create an off-screen canvas document (a Chrome MV3 API) to stitch multiple screenshot segments into a single image.
- storage — Required to save your extension preferences (format, quality, theme) locally on your device.
- <all_urls> — Required because users can capture screenshots of any website. The extension only acts when you initiate a capture — it does not run passively on pages or collect any page data.
Children's privacy
FullSnap does not collect any data from anyone, including children. The extension has no user accounts, no login, and no data transmission of any kind.
Changes to this policy
If the privacy practices of FullSnap change, this page will be updated. Given the nature of this extension (no data collection), significant changes are not anticipated.
