I don't collect information from you in my apps. None. No sign-ins, no emails, no location, no contacts... anything else you might think of, I don't.
I do count the number of times each page (including this one) has been looked at.
The logs look like this:
22.214.171.124 - - [30/Jul/2019:10:35:15 +0000] "GET /privacy.html HTTP/1.0" 200 930 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36"
They contain your IP address, the date and time, the page you looked at and what browser you were using.
The logs are deleted after 7 days.
