Google Chief Executive Sundar Pichai was warned that describing the company's Incognito browsing mode as "private" was problematic, yet it stayed the course because he did not want the feature "under the spotlight," according to a new court filing.

Google spokesman José Castañeda told Reuters that the filing "mischaracterizes emails referencing unrelated second and third-hand accounts."

The Alphabet Inc  unit's privacy disclosures have generated regulatory and legal scrutiny in recent years amid growing public concerns about online surveillance.

Users last June alleged in a lawsuit that Google unlawfully tracked their internet use when they were browsing Incognito in its Chrome browser. Google has said it makes clear that Incognito only stops data from being saved to a user's device and is fighting the lawsuit.

In a written update on trial preparations filed Thursday in U.S. district court, attorneys for the users said they "anticipate seeking to depose" Pichai and Google Chief Marketing Officer Lorraine Twohill.

The attorneys, citing Google documents, said Pichai "was informed in 2019 as part of a project driven by Twohill that Incognito should not be referred to as 'private' because that ran 'the risk of

exacerbating known misconceptions about protections Incognito mode provides.'"

The filing continued, "As part of those discussions, Pichai decided that he 'didn't want to put incognito under the spotlight' and Google continued without addressing those known issues."

Castañeda said teams "routinely discuss ways to improve the privacy controls built into our services." Google's attorneys said they would oppose efforts to depose Pichai and Twohill.
