Avoiding the app is not enough. The article is mostly about tiktok following you around the net with tracking pixels, without even having the app installed. They pay the biggest web companies to include tiktoks tracking pixel on their sites, just like googl and meta do. So yea: get a good adblocker.

Here's how it works. TikTok, for example, encourages companies to put pixels on their websites to help the social media giant harvest more data. Let's say I have an online shoe store. If I use a pixel, it lets TikTok collect lots of data about my customers in order to show them targeted ads. Plus, it helps TikTok figure out whether people who see those shoe ads end up making a purchase.

You can ask TikTok to delete any data it already has about you.

The problem is always that this is a "trust us!" situation. If I were an evil company and user Foo requested his data deleted, simply deleting it would be the worst possible choice. Something simple as creating another company that has a deal to buy data from you for cheapsies. They just happen to sell them Foo's data right before you deleted it. Oh well, you did delete it so. Or just don't delete it, just say you do (which is what I suspect most do anyway).

Those requesting data delete, are probably holding the most valuable data, maybe not for your company but for someone else.

It is very very hard to prove you have completely deleted something, maybe you just deleted 4 of the 5 copies.

Safari can block tracking pixels and other trackers natively.

Privacy Badger is redundant. You only need uBO
