Thanks for removing MixPanel, I think centralised analytics are by default going to breach privacy as you only need a referer and an IP address to have enough data to put someone's privacy at risk.
Also, third party JavaScript (not protected by code review and SRI) is an access control issue and can violate privacy at anytime as shown by instances of credit card theft and cryptomining this year.
Simply Analytics lies about not being a GDPR concern (which requires consideration for access control and security (loading third party JavaScript) and under GDPR IP address can be considered an identifier.

"Your personal information is generally stored until you advise us to close your Authy account and delete your records, and activity logs may be stored for up to a year for security purposes, or, if there is an ongoing investigation, until that matter is concluded."
This seems more like a list of alternatives to Google (which is still incredibly valuable), rather than a list of privacy-friendly alternatives.
That's still great though: I'm still happier to have some choice in who tracks me even if all alternatives do.
Happy to amend this response if creator finds a way to moderate it, but for instance MixPanel stole usernames and passwords earlier this year so definitely shouldn't be on this kind of list https://techcrunch.com/2018/02/05/mixpanel-passwords/
