As far as I know, I'm allowed to say that: people I work with tend to be liberal. As far I know, I'm also allowed to say that: people I work with tend to view data as a liability not an asset. It's also public information that Google receives billions of requests per day. For me to extrapolate on that and say that even storing a single bit of data on those logs starts to add up and cost a lot of money isn't a trade secret either. It's common sense.
A couple of actionable statements
- you don't store anything for more than 30 days (that doesn't mesh with analytics data which might be de-anonymisable IMO).
- you don't do any facial tracking. Which doesn't surprise me too much but I can imagine a future trial where a barrister is saying "your engineers claimed in public you didn't do this sort of tracking" and that providing extras jeopardy for damages.
It's not my area, however, I appreciate the openness. Thanks for sharing.
Take care!
