The EU's data watchdog is expanding its investigation of internet search engines beyond its current focus, Google, after the industry giant wrote to them last week.
Google told the Article 29 Data Protection Working Party that the company was ready to curtail the time it stored user data to a year and a half.
It was seeking to mollify the watchdog, which had questioned its privacy policies last month.
That storage time was at the low end of an 18- to 24-month period it had originally proposed to regulators in March.
The watchdog, made up of national data protection supervisors of the EU's 27 countries, said in May that Google seemed to be failing to respect EU privacy rules and asked for clarification before its meeting this week.
The body advises the EU on data protection issues, but its opinions are not legally binding.
