Privacy Policy
FullScreenie is a browser extension for capturing and annotating screenshots. This page explains, in plain language, what data the extension touches and what it does not.
The short version. Your screenshots stay on your device. We do not run analytics, we do not track you across the web, and there is no account to create. The only time anything leaves your computer is when you opt in to Share Link and click to generate one.
What we don't collect
FullScreenie does not collect any of the following:
- Browsing history
- Analytics or usage telemetry
- Tracking cookies or fingerprinting data
- Account information (there are no accounts)
- Personal identifiers of any kind
Screenshots you capture
Every screenshot is captured locally in your browser and saved to your device. The extension does not upload your captures anywhere by default. Standard captures move directly from the page to your downloads folder.
Share Link (opt in, off by default)
Share Link is the one feature that involves the network. It is disabled by default and shows a clear warning the first time you turn it on.
When you enable Share Link and click Generate Link in the editor, your screenshot is uploaded to Cloudinary (a third-party image host) through a Cloudflare Worker that we operate. The worker returns a URL that anyone with the link can open to view the image.
- Auto-expiring links: when you generate a link you choose its lifetime (1 hour, 24 hours, or 1 week). Non-permanent links are scheduled for automatic server-side cleanup once that window passes.
- Manual deletion: you can delete a shared image at any time from the extension's settings page. Deletion needs an internet connection and may take until the next cleanup cycle to fully propagate.
- Rate limiting: to prevent abuse, the worker keeps a per-IP request counter for one hour. No other request data is retained.
- Public by URL: share links are unguessable, but anyone who has the link can view the image until it expires or is deleted. Treat them like any other unlisted URL.
Capture History (opt in, off by default)
Capture History is a convenience feature that keeps a list of your recent screenshots in the extension popup. It is disabled by default. When you turn it on, the extension stores the following on your device only:
- A small JPEG preview of each capture, capped at 480 pixels wide
- The page URL the capture came from, with query strings stripped
- A timestamp, the suggested filename, and the browser's download ID for the file
None of this is transmitted off your device. The extension uses the unlimitedStorage permission because full-page screenshots can be large during processing. You can clear history at any time from the settings page.
Permissions, in plain language
- Active tab and scripting: needed to capture what is on the page you are looking at.
- Downloads: needed so the extension can save the screenshot file to your downloads folder.
- Storage and unlimited storage: needed to remember your settings and, optionally, to hold capture history previews on your device.
- Context menus: needed to add the right-click capture options.
- Website content (optional): requested only when you opt in to Share Link, because that is the moment the screenshot leaves the browser.
Third parties
The only third-party services involved are the ones used by Share Link:
- Cloudflare: hosts the worker that proxies upload and delete requests, and stores the per-IP rate-limit counter for one hour.
- Cloudinary: stores the uploaded image and serves it at the share URL.
We do not sell, rent, or share your data with any other third parties. There are no advertising or analytics partners.
Children's privacy
FullScreenie is not directed at children under 13 and does not knowingly collect information from them.
Changes to this policy
If this policy changes, the date at the top of the page will be updated. Material changes will also be called out in the extension's release notes on the Firefox Add-ons listing.
