What GambleBlur does
GambleBlur is a Chrome extension with a single purpose: it detects gambling-related content on web pages (text, links, ads, and images) and blurs it in place. Ambiguous content is classified by Gemini Nano, the AI model built into the Chrome browser itself, which runs entirely on your computer.
Data we collect
None. GambleBlur does not collect, transmit, sell, or share any data of any kind. Specifically, it does not collect:
- Personally identifiable information
- Browsing history or visited URLs
- Page content, images, or screenshots
- Health, financial, authentication, or location information
- Usage analytics, telemetry, or crash reports
How page content is processed
To do its job, GambleBlur reads the text and images of pages you visit — but this processing happens entirely inside your browser, on your device:
- Text analysis happens in the page itself and in the extension's local background process.
- Image analysis uses Chrome's built-in on-device AI (Gemini Nano). Images are fetched by your browser and analyzed locally; they are never uploaded anywhere.
- Verdicts are cached locally (as anonymous content hashes mapped to a blur/show decision) so the same content doesn't need re-checking. You can clear this cache anytime from the extension popup.
No page content, no image, and no URL is ever sent to us or to any third party. GambleBlur makes no network requests to any server operated by us — because we don't operate any.
What is stored on your device
- Your settings — on/off state, blur strength, per-site pause list, and deep scan preference — stored via Chrome's extension storage (and synced across your own Chrome profile if you use Chrome Sync).
- The local verdict cache described above.
Uninstalling the extension removes all of it.
Permissions, explained
- Access to websites you visit — required so the extension can detect and blur gambling content in place on any page, including inside ad frames, and fetch page thumbnails for local AI analysis.
- Storage — required to save your settings and the local verdict cache.
Third parties
The extension uses none. No third-party services, SDKs, analytics providers, or ad networks are included in the extension. The AI model (Gemini Nano) is a component of the Chrome browser itself, provided by Google as part of Chrome, and runs offline on your device.
This website (not the extension)
This informational website uses Microsoft Clarity to understand anonymous, aggregate usage of the site itself — such as which pages are viewed and how visitors interact with them. This applies only to this website. The GambleBlur extension contains no analytics of any kind and never communicates with this website or any other server. See Microsoft's privacy statement for how Clarity handles data.
Children's privacy
GambleBlur does not collect data from anyone, including children.
Changes to this policy
If this policy ever changes, the updated version will be posted at this address with a new "last updated" date. Since the extension's design is no-collection by architecture, meaningful changes are not anticipated.
