Browser Extensions

Small tools that stay on your machine.

Free extensions built alongside the websites we make. Every one of them runs its checks in your browser: no account, no server, nothing uploaded.

What every one of them does

Built to the same standard, so knowing one tells you what to expect from the rest.

Runs in your browser

No account, no login, no server to upload to. What the extension works out, it works out on your machine and keeps there.

No analytics, no telemetry

Nobody at Elevven11 Studio can see what you browse or what you do with these tools. Opening one makes no request and tells nobody it was opened.

Permissions explained, not buried

Nothing is requested that is not used, and each extension lists every permission and what it is for, in its settings page and its policy. Where one can work without broad access it asks late and lets you withdraw it; where protection genuinely needs it up front, it says so rather than pretending otherwise.

Free, and staying free

No paid tier and no trial. Each one carries a single house advertisement for the studio's own work, labelled "Ad", which one click turns off permanently.

A policy per extension

Each one publishes its own privacy policy saying exactly what it reads and what it stores, rather than pointing at a single studio-wide page that describes none of them.

Honest about limits

A check that could not run is reported as exactly that, not as a failure. Where a tool is guessing, it says it is guessing and shows you what it is guessing from.
