Dark pattern: design that steers people into choices they didn’t mean
A pre-ticked box, a fee that appears at the last step and a cancel button buried 4 screens deep are each a design choice that works against the person using it.
A dark pattern is a design choice in a website or app that pushes people into a decision they didn’t mean to make, such as buying, subscribing or sharing data, or makes the choice they want harder to take. Many appear only past a sign-up, in a checkout or in a cancel flow, so a compliance team sees them only by going through as a customer.

Dark pattern examples
The US Federal Trade Commission published its staff report Bringing Dark Patterns to Light in September 2022. It describes design practices that can trick or manipulate people into buying or giving up their privacy. Its announcement groups the common tactics into 4 kinds.
- Disguised ads: advertising designed to look like independent editorial content.
- Hard to cancel: charging people without consent, or making a subscription difficult to leave.
- Buried terms and junk fees: material information hidden until late, such as a fee first shown at checkout.
- Tricks around data: choices about privacy settings presented so that people share more than they meant to.
Others are familiar from everyday shopping. A pre-ticked box adds insurance to a basket. A countdown timer resets when the page reloads. In confirmshaming, the button to decline reads “No thanks, I prefer paying full price”.
Where dark patterns meet the law
In the EU, Article 25 of the Digital Services Act, adopted on 19 October 2022, bars providers of online platforms from interfaces that deceive or manipulate the people using them. It lists “making the procedure for terminating a service more difficult than subscribing to it” among the practices the European Commission may issue guidelines on. Subscription exits have rules of their own, covered under click-to-cancel. This is general information, not legal advice.
How dark patterns are found and kept as evidence
Many dark patterns sit behind a login wall: the fee added at checkout, the save offer that has to be refused three times, the cancel link hidden in account settings. A design review of the public site misses them. Product and compliance teams find them by going through the journey as a customer and keeping a screenshot of every step, then repeating it after each release.
Obsession collects what companies show only to customers, step by step: their screens, emails and texts, member prices, trial limits, quotes and cancel offers, each dated with a screenshot. Teams and AI agents look up any company through the API or MCP, and a company not yet covered is added on request. For dark patterns, that means every screen of a checkout or cancel flow as a customer met it. Each is dated, so a fee added at the last step is on file as it looked that day. Compliance teams use the record for a dark patterns audit of their own flows and competitors’.
Some are, depending on the practice and the country. In the EU, the Digital Services Act bars online platforms from interfaces that deceive or manipulate users. This is general information, not legal advice.
Confirmshaming is wording that makes the person feel foolish for declining, such as a button that reads “No thanks, I don’t like saving money”.
Not by itself. A single offer to stay, with a clear way to carry on cancelling, is ordinary retention. It becomes a dark pattern when it stands in the way of the exit.
