Cookie Policy

Keeps you signed in between visits.

Stored in your browser local storage rather than in a cookie. Cleared when you sign out.

Remembers whether your sidebar is open or collapsed.

This is the only cookie Locker sets. It holds a single true or false value, contains no personal data, and expires after seven days.

Remembers small choices you have made in the app.

Things like panel heights and playback preferences, stored in your browser local storage. They never leave your device.

Tells us which pages are slow or failing.

We use Vercel Analytics and Speed Insights on the live site. These are cookieless: they set no cookies, assign no persistent identifier, and cannot follow you to other websites.

Tells us which of our pages lead people to sign up.

While you are signed out, Locker counts which of its public pages you open and which main buttons you press, such as Sign up or Download. It uses a random number kept only in that browser tab, which is gone when you close it. It also notes the time zone your device is set to, which tells us roughly which country visits come from without using your IP address. If you arrived from a link with a campaign tag, such as a LinkedIn post, that tag is kept in local storage for up to 90 days so a sign-up can be credited to it. There is no cookie and no name, and nothing follows you to other websites. If your browser sends Global Privacy Control or Do Not Track, nothing is counted.
