In quite a few countries, you connot legally test if a child is yours (as a man). Websites that do not care about privacy can "help" you! Ancestry and MyHeritage let you send in your DNA swab, an tell you where you are from. Open a second account, and send a swab from the kid, and they will tell you about your "newly found" relative. No questions asked.

Giving such a site my DNA is the worst thing I could do, BTW. This is an example how much privacy can be broken.

If you use Fennec/Firefox on Android, you should consider the First Party Isolation addon. All it does is to eneable or disable the first party isolation. In Android there is no switch, so you else need to fiddle around in about:config.
This protects against cross site tracking, but your logins still work.

When you write or sign legal documents with date, do not write 1-1-20 this year, always write like 1-1-2020 this year. Because it is easy to fake 1-1-20 to 1-1-2019 or any other year in 20xx.

Linux date is now 50. It started 01-01-70.

If you use public USB charging outlets, make sure you have a charging only cable. These cables have no data lines. I got mine fit $1 in a cheapo shop.
If you use a cable with data lines, the outlet might do more than charging...

There is a cute Dutch film about a psychology student being terrorized by an app on here smartfone. If you have a possibility to see it, it is real fun.

If you want to remove all data from an Android device, this is what I would do:

Do a reset/wipe.
Set it up with encryption and a new Pasword, let it encrypt.
Do a reset/wipe.

(If you want to give it away, remove your google account before doing the above.)

German state authority "BSI" has withheld information about security problems in Truecrypt for almost 10 years. These could still effect Veracrypt.
This authority is supposed to help citizens keep their computers secure. But obviously they are not to be trusted.

Many ISPs give you a new IP each time you disconnect and reconnect. That makes you much harder to track.
Many routers can be set to reconnect each day. Use that setting if you can.
With mobile devices swith off mobile data over night. That also saves battery.

Does anybody know of an alternative sync server for Firefox. Not run by Mozilla and peferably in Europe.

I just had a look at the "Masterpassword" app for Android. Do not use it!

You enter your name which is saved. When you enter a URL it generates a password from name and URL. So far so good. But then you should click the password to copy it into the clipboard. That is really bad, as the clipboard can be read by any app, any time. So you are lured to publishing your password. Why do folks who claim to give you security publish such crap?

Just in case you think buying a Oneplus is a good idea, pay cash if you can. Else, your privacy might be disturbed.

If you understand the meaning of Scotts advice you should also consider the Private Lock app. It locks your phone when snatched (by officials) or dropped (by you) by using the motion sensor.

I am using DoH for over a year, and often get heat for advocating it. I like one sentence in an article article that @ScottMortimer mentioned which says that DoH:
" freaks out ISPs, makes Enterprise IT and Security nervous"
That is one reason why I like (and use) DoH. In the end DoH lets me take more control over my net usage.
