For me I used to donate to Mozilla about £10 a month but have since stopped.
Lemmy devs: ~20$/year
Joplin: ~1$/month
Cryptomator: I bought the supporter license on desktop and the mobile app on both iOS / Android, if you can consider that donation
Internet Archive: ~20$
Signal Foundation: ~5$
Wikipedia: ~10$KDE is one of the few I always have in my list. No matter the OS I use, I always end up using KDE and highly prefer it over anything else I’ve tried. So it’s my way to contribute to not hate the time spent at my computer in the near future.
Local food bank is a good one around where I am located
Edit: didn’t notice the community
Privacy wise I donated to Signal for a bit. Hope to donate to more things eventually
I’m in the same boat, biggest donation by far is to my local county charity, with a focus on food security and childhood development. Other than that I donate to Lemmy and Bitwarden (I kinda earmark that as a donation in my mind?).
Not entirely privacy related but: The Electronic Frontier Foundation, Wikipedia, Doctors Without Borders, The National Park Service, RAINN, and Red Cross
