Privacy policy

The short version

Everything the extension stores stays on your own machine. It has no permission to reach the network on its own. The only data that ever leaves your browser is anonymous usage telemetry, it is off until you turn it on, and it cannot carry anything that identifies you.

What is stored on your device

Your sessions and the cookies inside them, your settings, and the extension's own journal. These live in your browser profile on your computer. They are not uploaded, backed up, or synchronised anywhere. Uninstalling the extension removes them.

Cookies are copied into a session, never moved out of the browser's own store, so your normal browsing is unaffected by anything you do here and nothing is deleted on your behalf.

What leaves your device

Only telemetry, and only if you enable it. It is anonymous, it is limited to a fixed list of values, and it contains no free-form text of any kind. The complete list is published at what it collects, generated from the same definition the server validates against.

It specifically never includes URLs, page contents, cookies, account names, email addresses, or any fingerprinting material such as screen size, canvas output or your font list.

An installation identifier is included so that repeat activity can be counted. It is random, it is created at install time, and it is connected to nothing else. Turning telemetry off erases it.

What is never collected

Your name, email address, or any account credential. Your browsing history or the addresses of pages you visit. The contents of any page. Your location, whether from an address, a named timezone, or anything else. There is no advertising identifier, no cross-site tracking, and no profile of you built anywhere.

Selling and sharing

Nothing is sold. Nothing is shared with any third party. There is no third-party analytics, advertising or tracking service in the extension or on this website. There is no data to sell, which is the intended design rather than a current position.

Who holds it

Telemetry, if enabled, is stored in a database controlled by the author and readable only by the author. It is retained to understand how the extension is used and how often it fails.

Your choices

Turn telemetry off at any time in the extension's settings, which stops collection and erases the installation identifier. You may request deletion of data associated with your installation identifier by writing to envxsion@proton.me. Because the data is anonymous, you will need to supply that identifier from the extension's settings for it to be found.

A risk worth naming

Signing into a federated provider such as Google inside a session can, in rare cases, leave a partially written login. Providers treat that as a possibly compromised session and may sign you out across your devices. The extension detects this pattern and steps back rather than retrying into it, and signing in fresh inside a session avoids it. It is disclosed here because it is a real consequence of using the tool.

Children

This is a developer tool and is not directed at children. No data is knowingly collected from anyone under 13.

Changes

If this policy changes, the date at the top changes with it. Material changes to what is collected will also appear in the extension's changelog.
