UK Gambling Licence Check: Privacy and Data Use
Read the UK Gambling Licence Check Chrome extension overview for its purpose, scope and stated limitations.
This page explains the privacy and data handling information for CasinoGauge’s UK Gambling Licence Check Chrome extension. It covers extension version 1.0.0 as listed in the Chrome Web Store on 2 September 2026. The extension is an independent tool and is not operated or endorsed by the Gambling Commission.
Last checked: 24 September 2026. Product details and store disclosures can change; check the current Chrome Web Store listing before installing or updating.
What the extension reads
When you click the extension button, version 1.0.0 reads the active tab’s URL and uses its hostname for a local lookup against a copy of the Gambling Commission’s published licensed-domain register. The inspected package code uses the tab URL to obtain the hostname; it does not include a content script. The result may display the matching register entry and its licensee details. A register match is not a review or safety rating.
Permissions
The published package manifest lists the activeTab and alarms permissions. It also defines an optional host permission for https://www.gamblingcommission.gov.uk/*. The optional permission is used for register updates; it is not required for a local lookup against data already available to the extension.
Local register data and updates
The package includes a register snapshot. If a register is imported or refreshed, the extension stores the register on the device in its extension storage. No CasinoGauge account is needed. The package’s optional refresh function requests the Gambling Commission’s published CSV without credentials after the relevant permission is granted. You can also import a register file through the extension’s setup page.
In a limited static inspection of the published version 1.0.0 package, I found the local lookup and register-update paths described above and did not identify an analytics or advertising integration. This was not a full security audit or a live test of every browser state.
Chrome Web Store privacy disclosure
When checked on 24 September 2026, the Chrome Web Store privacy section listed these data categories for the extension: personal communications, location, and website content. The same listing says the developer declares that data is not sold to third parties, is not used or transferred for purposes unrelated to the extension’s core functionality, and is not used for creditworthiness or lending decisions. These are the developer’s store disclosures; the public listing does not explain how each broad category maps to a specific extension operation.
The listing’s overview also describes the lookup as local and says “no tracking”. Because the store’s category disclosure is broader, this page reproduces both pieces of information rather than treating the short description as a complete independent privacy audit. Review the store privacy details and permissions before installing.
What the inspected package does locally: In version 1.0.0, clicking the extension button on a normal website lets the popup read the active tab’s URL. The code extracts the hostname and compares it with the bundled register or a register you imported. In the package reviewed, this lookup stays in the browser; I found no code path sending the checked URL or hostname to CasinoGauge. Google treats website domains and URLs as browsing-activity data, including when an extension processes them locally, so this local access is disclosed here. See Google’s Chrome Web Store User Data FAQ.
Optional register refresh: If you grant the optional Gambling Commission site permission, the extension can request the Commission’s published domain-register CSV over HTTPS, including through its scheduled refresh. The request uses a fixed Commission URL, not the website domain being checked. It sends no credentials in the reviewed code. Chrome Web Store’s current privacy panel separately lists Personal communications, Location, and Website content; the inspected package explains the local website-domain lookup but does not reveal why the other two categories are declared. The Store disclosure is the developer’s current statement; this code review does not verify the private dashboard settings.
What the check cannot tell you
The extension compares a domain with a dated register snapshot. It cannot confirm that a gambling service is safe, that its terms are fair, or that it is suitable for you. A “not listed” result is not, by itself, proof that a site is unlawful; the register may be out of date or the site may not offer gambling in Great Britain. Confirm important results against the Gambling Commission’s public register.
