Start selfhosting.

Most of the most useful services can be easily selfhosted. And that’s an incredible amount of info that stays at home

You can start by looking up your name on major search engines and delete social accounts that are yours, and for the people search websites some of them have opt outs but most are really annoying and don’t comply (in my experience)

Consider using a privacy respecting browser like Firefox with the extension uBlock origin. Keep it to a max of two other extensions because it makes your browser more identifiable.

Consider using open source software over closed source software (just because it’s open source doesn’t mean it’s always safe)

For email I use proton mail and I’ve been very happy with it along with there other stuff.

As some other people have mentioned, self hosting is a good option if you have the time for it, and a spare computer laying around.

I would look to someone such as Michael Bazzell, he has a great podcast "the privacy, security and OSINT show. He offers loads of information on privacy and can advise on what you are looking for. Check his website : https://inteltechniques.com/index.html
