An independent project — a real person reads every message

Check My Setup is a small, independent tool built and maintained by one person in the UK. Whether you've spotted a bug, want to suggest a feature, need to exercise a privacy right, or just have a question about what the tool shows you, get in touch using whichever address fits best. I aim to reply within a few working days.

What to include

If you're reporting something that looks wrong — say the location or ISP shown doesn't match reality — it helps to mention your browser, whether you're on a VPN or mobile network, and what you expected to see. That context lets me reproduce the issue quickly. You don't need to send screenshots; the "Copy share link" button on the homepage creates a snapshot you can paste into an email.

Who you're contacting

Check My Setup is operated by Marcin Lewandowski, trading as Depthia — a sole trader registered in the United Kingdom, registered with the UK Information Commissioner's Office under number ZC164548.

Postal address: Depthia, 66 Paul Street, London EC2A 4NA, United Kingdom.

Before you email

A lot of common questions — why your city looks wrong, what an ASN is, whether your data is stored, how the fingerprint works — are already answered in the FAQ on the homepage and explained in more depth on the blog. It's worth a quick look; you might get your answer instantly.
