Password data not accessed
Last but not least, Mixpanel says it audited servers to determine if anyone had accessed the accidentally collected data.
"We do not believe this data was downloaded or accessed by any Mixpanel employee or third party," Mixpanel said in its email.
"It was a bug, plain and simple," the company said, highlighting there was no malicious intent.
A full copy of the email has been
uploaded to Reddit on February 1, when the company started notifying customers. TechCrunch, who first reported on the incident, has validated the email's authenticity.
Some users showed displeasure with Mixpanel for waiting almost a month to let them know about the incident. The company is now urging developers to update the Mixpanel SDKs used inside their products.
