European gym chain Basic-Fit disclosed a breach affecting approximately 1 million members in April 2026. The exposed dataset includes bank/SEPA direct-debit details and fitness-profile data alongside standard contact details. Direct-debit account numbers in the wrong hands enable downstream fraud against the customer's bank account.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What to do now

Steps that match what this notice says was exposed

Every step below is free and you do it yourself, and none of it depends on Basic-Fit Gym.

Tell your bank before you do anything else. Account and routing details are the fastest-moving of the fields in this notice. Call the number on the back of your card rather than any number in an email, and ask them to watch the account and reissue the card.

One more, whatever was exposed: a breach notice is a favourite disguise for a phishing email. If a message about this arrives, do not use its links — go to the company’s site yourself, or call the number on your statement.

Check your exposure

Basic-Fit Gym is one listing. Your email is probably in others.

~1 million accounts were exposed here. We can’t confirm any single incident against the sources we search, so we won’t pretend to — what we can show you is your own exposure: every leak and listing tied to your email, in about 15 seconds. No account, no card.
