Privacy Policy — Leak Check by FreedomRouters
Last updated: 15 August 2026
Leak Check is a browser extension that shows you what your own browser reveals to the websites you visit: your public IP address, your approximate location, and whether your connection leaks identifying information through WebRTC, DNS, timezone, or browser locale. This policy explains exactly what the extension does and does not do with data.
The short version
- The extension runs its tests only when you open it or when it refreshes its status badge.
- It does not track your browsing, read the pages you visit, or log your activity.
- It stores nothing about you on any server. The only thing kept is a single result summary saved locally on your own device.
- To run the tests it must ask a few diagnostic services for your public IP and its location. That is the extent of what leaves your browser, and it is your own network information, requested so it can be shown back to you.
- We do not sell, rent, or share your data with anyone, and we do not use it for advertising, profiling, or credit decisions.
What the extension accesses
To tell you what your browser exposes, the extension reads the following, each time it runs a scan:
- Your public IP address, by asking a public lookup service what address your requests come from.
- The approximate location of that IP (country, region, city, and the coordinates the IP maps to), by looking that IP up in a geolocation service. This is the location associated with your internet connection, not GPS, and not your device's precise position.
- WebRTC candidate addresses, read locally from your browser's own WebRTC interface, to detect whether your real address leaks around a VPN. This is read inside your browser and is not sent anywhere.
- Your device timezone and browser language, read locally from your browser, to compare against your IP location. These are read inside your browser and are not sent anywhere.
- DNS resolver information, by triggering lookups of randomly generated test hostnames and asking a DNS-leak service which resolvers performed them. These test hostnames are synthetic; the extension does not send, read, or log the actual websites or domains you visit.
Third-party services the extension contacts
Running the tests requires contacting a small number of diagnostic endpoints. The only information sent to them is the network request itself; the extension does not attach your name, an account, an identifier, or your browsing history to these requests.
| Service | Why it is contacted | What it receives |
|---|---|---|
ipify (api.ipify.org, api64.ipify.org) |
Returns your public IPv4 and IPv6 address so the extension can show it to you. | The request itself, from which your public IP is visible (as it is to any website). |
| ipwho.is | Returns the approximate geolocation and network operator for an IP address. | The IP address being looked up. |
| bash.ws | Performs the DNS-leak test and reports which DNS resolvers were used. | Requests to randomly generated test hostnames. No real browsing data. |
Each of these is an independent third party with its own privacy practices. The extension uses them only to retrieve the diagnostic information described above and for no other purpose.
What is stored, and where
- On your device only: the extension saves a small summary of your most recent scan (an exposure score and a status) using your browser's local storage, so its toolbar badge can reflect your last result. This never leaves your device and you can clear it at any time by removing the extension.
- On our servers: nothing. This version of the extension does not transmit scan results, analytics, or any user data to FreedomRouters or to any server we operate.
Browser permissions and why they are needed
| Permission | Reason |
|---|---|
storage | To save the last scan summary locally so the toolbar badge stays current between sessions. |
alarms | To schedule a periodic lightweight background check that updates the badge when your IP or timezone changes. |
| Host access to the diagnostic services listed above | To make the network requests that retrieve your IP, its location, and DNS-resolver data. |
The extension does not request access to the websites you visit, does not inject scripts into web pages, and contains no content scripts. It cannot read or modify the content of the pages you browse.
What the extension does not do
- It does not track, log, or transmit your browsing history or the pages you visit.
- It does not record clicks, keystrokes, scrolling, or other activity.
- It does not collect personal information such as your name, email, or payment details.
- It does not use cookies or advertising trackers.
- It does not sell or transfer your data to third parties, and does not use it to determine creditworthiness or for lending.
Product recommendations
When the extension detects that your real location or network is exposed, it may show a recommendation for a FreedomRouters privacy product relevant to the finding. These recommendations are generated locally inside the extension based on your scan result. Clicking one opens a FreedomRouters product page in a new tab. Whether you click is your choice, and the recommendation itself does not transmit your scan data anywhere.
Children
The extension is a general-purpose privacy tool and is not directed to children, and it does not knowingly collect any information from children.
Changes to this policy
If a future version of the extension changes what data it handles, this policy will be updated before or alongside that release, and the "Last updated" date above will change. Continued use of the extension after an update means the revised policy applies.
