Officials at the Yorkshire-based chain told buyers their bank details were safe, but warned them to avoid emails or phone calls from the company.
Hackers have stolen thousands of details from customers of Britain’s best-known tea shop chain.
Online shoppers around the world have been alerted to the security breach at Yorkshire-based Bettys.
The company, which sold an enormous amount of goodies such as cakes, teas and coffee in its traditional tearooms, moved to reassure customers around the world that their vital bank details had not been stolen.
But he admitted that details of clients’ names, home addresses, email addresses, passwords and phone numbers were illegally accessed.
Director Paul Cogan cautioned online customers, “I’m sorry to have to tell you that the Bettys.co.uk website has been affected by a data breach.
“We are contacting you because you are on our database and will have been affected. This data breach occurred due to an industry-wide software weakness. Details that may include names, email addresses, postal addresses, encrypted passwords, and phone numbers have been copied.
“Credit or debit card details have not been copied.”
Mr Cogan added, “If you are using the same password on other websites, please change those passwords. Phone calls or emails claiming to be from Bettys should be treated “with extreme caution,” he said.
“We will never contact you to ask you to share personal financial information. “
The company took customer privacy “extremely seriously” and a full investigation was launched, he added.
Bettys, a northern institution, opened its first teahouse in Harrogate in 1919 and now has six traditional Yorkshire teahouses, as well as its own bakery and online business thriving around the world.
