When a sign-up is effortless but cancelling is a maze, when fees appear one screen at a time, when the "no thanks" is worded to make you feel cheap — that's not your carelessness. It's design, on purpose, to get you to pay more and stay longer. These tricks have a name — dark patterns — and once you can see them, most of them stop working.
Spot the trick
Tick what you're seeing in the sign-up, offer, or checkout. Nothing is saved or sent.
Before you commit
A 60-second pass for any sign-up or checkout. Tick as you go.
The close
None of these tricks survive an unhurried minute. They're built for the moment you're rushing, distracted, or worn down — so the whole defense is to refuse that moment: find the exit before the entrance, read the boxes, wait for the real total, and let the countdown run out. When a company has to win your business honestly instead of trapping it, you've already won.
