Online food and nutrition website and app MyFitnessPal has seen a data breach of their users information.
It became aware of the issue on March 25th, but actual breach took place in February.
In an email the company behind the app, Under Armour, said the affected information included usernames, email addresses and hashed passwords.

However it said this did not include payment card data as it is collected and processed separately.
It is thought up to 150 million accounts have been affected.
It also said it is notifying users to provide information on how they can protect their data, requiring them to change their passwords immediately and monitoring for suspicious activity.
The company added that it does not know the identity of the unauthorised party, and that an investigation is ongoing.
