I’ve recently found that when I visited a website of an app I once used, rejected the cookies, that once I left the site I got an email from the company. This has happened twice and is quite disconcerting. It seems the site is knows who I am and then sends me an email.
How do all you clever techo’s deal with this issue?
How long ago did you use the app? Did you have an account of some sort on their website? Any chance they’re able to match your account just by IP address?
In case you don’t know yet, this might be an interesting read:
There are companies (e.g. LeadForensics) that can figure out who you are and associate with contact information. They use some automated methods, but they also spend a lot on humans to connect data, validate/verify etc. I’ve helped implement that particular company for clients (sorry.)
There are some anti-fingerprinting steps you can take with your browser. Good adblock also helps since a lot of these use detectable JS scripts to identify you. If the JS can’t run, all they have is your IP hitting a server, which you can mask with a VPN or Private Relay.
There’s definitely more they can do and track, per Rob’s link, and more you can do, too.
You can also run a fingerprint check from the EFF:
I’ve had the app ages. Maybe it is ip, but mine is a range of ip’s from my host.
What apps or options help minimize this?
“Resistance is futile”, I’m afraid…
(I have experimented with apps and browser extensions, but most made my fingerprint more unique…)
I delete my history every time I finish using a browser. Been doing it as long as I can remember.
