We have a 6-person team coordinating our field operations and customer deliveries. Over the past two years, we've saved hundreds of customer addresses, custom labels, and routes on Google Maps, using both shared company Gmail accounts and work profiles on the staff's personal phones. Critical customer locations, delivery gate codes, and every single stop our staff made during the day have piled up in the timeline across these accounts.
Two employees left last month, and when we tried to wipe the map history while taking back the devices, we noticed the data wasn't fully deleted. Even after removing labeled places, past routes were still sitting right there in the search history and timeline section. What's worse, this data might have also backed up to the departed employees' personal accounts.
How can we permanently delete these saved addresses, labels, and past routes for both corporate security and customer privacy? What kind of wiping and auditing policy should we put in place for company devices?
