Information such as the date, time, IP address and phone number of a contact may be recorded as Apple determines who is, and is not, within Apple's messaging network, The Intercept's Sam Biddle reported on Wednesday. The logs, which are retained for about 30 days, may be subject to court orders, The Intercept said, based on a document it obtained.
Apple did not immediately respond to CNBC's request for comment.
Because iMessage is encrypted, Apple told the Intercept it did not have access to the contents of the messages. Still, the report comes after the company fought a high-profile battle with the FBI over privacy, notes The Intercept, known for its cybersecurity coverage since it was co-founded by Glenn Greenwald, who reported on Edward Snowden.
