Some new cameras have GPS chips built into them to record that meta data. However, a lot can be done when you have the pictures on your computer, provided it’s not in an area that is automatically shared.
If you do want to send a picture to a place like Walgreens to get it printed out, you can always bring it on a memory card instead of transmitting it over the Internet.
Also, if you are using Windows 10, if you right click on a photo (.jpg, .png, etc.) and go to the details tab, it will have a list of all the meta data stored with that photo. There’s a link at the bottom of the window that will allow you to strip personally identifiable metadata. I’m sure there are other programs you can download which can automate stripping metadata off of image files.
Sometimes the data can be useful. I have an older Nikon D5100 that doesn’t have GPS or WIFI capability on it, but records the camera settings (shutter speed, aperture, etc.) used when the picture was taken.

You can also take a gander with online applications, like this site. You can either give the online address of an image to analyze for metadata or upload a pic from your device.

If you run the image of Mona Lisa at the image address below through that site, you’ll see the Gettysburg Address in the metadata.
