I use Plausible, an open-source analytics tool, to track page views and referrals in an anonymous way.
Various forms are available on this website. They are here to be submitted and are sometimes sad when you don't.
Some lead to prefilled tweets over on Twitter (these didn't age well) You can then decide whether to tweet them or not.
Others send me a message on a personal Slack only I have access to. These get stored for up to 90 days. Past that delay, I might remember about them, but I can't help with that.
This policy is for sure not very professional nor legally correct. Actually, I'm not even obliged to have one (I guess? that's my understanding), so consider it here for transparency purposes~ (it was fun to write though!)
That being said, if you have any privacy-related questions, you can send them to me at firstname.lastname@example.org, which is really just an alias of email@example.com
