The short version
Endpoint Atlas collects nothing, sends nothing, and stores nothing off your device. It runs locally in your browser, reads only the Swagger UI page you have open, and makes no network requests of its own.
This policy describes how the Endpoint Atlas browser extension (the "extension") for Chrome and Firefox handles information. It applies to the extension itself, not to any Swagger UI page you open with it. The websites where Swagger UI is hosted are operated by their own owners and are governed by their own policies.
The extension does not collect, transmit, sell, share, or store any personal data. Specifically, it does not:
There is no backend. There is no account. There is nothing to opt out of, because there is nothing being collected to begin with.
<all_urls>Swagger UI is self-hosted documentation — there is no central domain it lives at. Every API team hosts their own Swagger docs on their own URL: api.company.com/docs, internal.example.org/swagger, localhost:8080/api-docs, and so on. The extension cannot know in advance which sites are Swagger UI pages.
For this reason it requests the <all_urls> host permission. This permission allows the content script to run on each page you open so it can detect whether Swagger UI is present in the DOM and inject the sidebar only when it is. On every other page the script does nothing and exits.
The permission is used purely to discover where Swagger UI is rendered. It is not used to read, modify, or transmit anything from non-Swagger pages.
On a Swagger UI page, the extension reads only what Swagger UI itself has rendered into the page: endpoint paths, HTTP methods, tag groupings, and the visible state of the Authorize dialog. It uses this to populate the sidebar and to display whether you are currently authorized.
This information stays in the tab. It is not copied off the page, sent to a server, written to your filesystem, or shared with any other extension. When you close the tab, it is gone.
The extension does not use chrome.storage, localStorage, sessionStorage, IndexedDB, cookies, or any other persistent storage to retain information about you, your browsing, or the APIs you view. The only persistent artifact on your machine is the extension's own code, installed by your browser when you added it.
The extension contains no third-party scripts, no advertising, no analytics SDKs, and no remote code loading. It does not share data with third parties because it does not have any data to share.
The extension is a developer tool and is not directed at children. Because no data is collected, no data about children — or anyone else — is processed.
If the extension's behavior ever changes in a way that affects privacy — for example, if a future feature genuinely required network access — this policy will be updated and the "Last updated" date at the top of the page will be changed accordingly. Material changes will be reflected in the extension's release notes on the Chrome Web Store, Firefox Add-ons, and GitHub.
Endpoint Atlas is free and open source. You can read the full source code, file an issue, or send a pull request on GitHub. For privacy-specific questions, please open an issue on the project's repository.
