Limited use disclosure

This page exists because browser stores require it, and because it is the plainest way to say what the extension does with the broad permissions it asks for.

Why the extension needs access to all sites

Identity-resolution pixels can be embedded on any website. To tell you when one fires, the extension has to observe network requests on every page you visit. It matches each request against a list of known broker hostnames and script paths. That list is public and ships with the extension.

What stays on your device

• The list of sites where a detection happened, and which broker, kept for 7 days to power the badge and the weekly digest.
• Your settings.

What leaves your device

• Once a day, a count of detections per broker for the current week and a random install id. Nothing about which sites you visited.
• Nothing else. The extension makes no other network requests except to fetch an updated broker list from this domain.

How we use that data

To know which brokers are most active across users and how many installs are active each week. It is shown on a private stats page and may be published in aggregate (for example, “Retention.com was detected by 40% of installs this week”). It is never used for advertising, never sold, and never combined with other data to identify you.

Chrome Web Store user data policy

Our use and transfer of information received from Google APIs and of data collected through the extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. The extension does not collect browsing history, page content, or personal communications.

Firefox

The same applies to the Firefox add-on. Its data collection permissions declare only the anonymous counts described above, and you can opt out of them in settings.
