What this is about. Almost every tool I try, and AI and developer tools most of all, wants a card number before the "free" part starts. This was called Fraud a few years ago and pornsites used it all the time (you should know :). Now, the company is betting that day 15, or whatever, arrives before I remember and it is just called business as usual. Here's how to make that bet lose, and where the popular tricks quietly fail.

I hereby declare WAR on Darketing!

Why. The tricks that circulate online are just half right. A declined card doesn't end a contract, and cancelling on day one sometimes ends the trial on day one too.

The card that says no

The favourite trick is a virtual card with a tiny limit. Privacy.com in the US, or a disposable card from Revolut in Europe. When the trial converts, the billing robot knocks, the card says no, and nothing happens. Nice.

Three catches, though:

• Privacy.com is US-only. It needs a US bank account. Outside the US you're looking at your own bank's virtual cards, Revolut, or similar.

• A disposable card dies by design. Revolut's disposable card gets new details after every successful payment, so it can't carry a subscription at all. Fine for a trial, useless the day you actually want to pay.

• A refused payment isn't a cancellation. The contract you clicked "agree" on is still there. The company can retry, suspend your account, or send you a bill. Most won't chase you for one month of a $20 tool, but some do, and an unpaid invoice is a worse souvenir than a charge.

So the burner card is a seatbelt, not the brakes. Use it, and cancel anyway.

Cancel on day one, but read the screen first

The other classic: sign up, then go straight to settings and cancel. Lots of services let you keep the remaining days. Apple's App Store and Google Play both keep a cancelled trial running to the end.

Not everyone plays along. Spotify ends Premium the moment you cancel a free trial, in most countries. Apple's own Music and TV+ trials have done the same in some places. Nothing in the law says you get to keep the rest of the days. It's the company's choice.

The cancel screen almost always tells you. If it says access ends now, back out, and put a reminder in your calendar two days before the charge instead. Two days, not one: time zones and "billing runs at midnight" have eaten many a last-day cancel.

What the rules already say

You have more on your side than the trial page suggests.

Visa has required since April 2020 that a merchant sends you an email or text at least seven days before the first charge after a trial, with a way to cancel online, and that the first charge says "trial" on your statement (Visa's rules). Mastercard has similar trial rules. No reminder email? Tell your bank when you dispute the charge.

In the EU, you get 14 days to withdraw from an online contract, and since 19 June 2026 online shops must give you a withdrawal button to do it. But the EU Court of Justice ruled in 2023 that a trial which turns into a paid subscription gives you that right once, at sign-up, as long as you were told the full price then (the ruling). The conversion doesn't restart the clock. Germany and France already require a plain cancel button, and the EU's coming Digital Fairness Act takes aim at subscription traps more broadly. In Sweden, where I live, the consumer authorities' line is that cancelling must be at least as easy as signing up. Very fuzzy and typical Swedish imho.

In the US, the FTC's "click to cancel" rule was struck down in July 2025, on procedure rather than principle, and the FTC started over in 2026. Enforcement didn't wait: Amazon agreed in September 2025 to pay $2.5 billion over Prime sign-ups and cancellations (Axios), and Adobe settled its case over early-cancellation fees in March 2026. Several states, California among them, have their own easy-cancel laws.

In the UK, a new subscription regime starts in January 2027, with reminders before a trial ends and a cooling-off period at renewal.

Or skip the bet

The best trial is the one that never needs a card. More and more of what I'd otherwise rent, I run myself. My sites serve their own fonts instead of borrowing Google's, and count their own visitors instead of renting a dashboard. Open-source AI models run on an ordinary computer now, and for a lot of everyday work they're good enough.

Self-hosting isn't free either. You pay in time, in updates, and in the evening when something breaks and there's no support desk to email. It pays off for things you use every day. For a tool you want to test for an afternoon, the burner card and a calendar reminder are cheaper.

What works, and what each costs

• A trial that bills by default. Beat it with a calendar reminder two days early, not one.

• Cancelling ends the trial at once. Read the cancel screen; if it says "now", set the reminder instead.

• A charge you never expected. No seven-day reminder breaks Visa's rules. Dispute it with your bank.

• Being locked in for good. Self-host what you use daily, and pay in time instead of money.

Rule of thumb: the company bets on your memory, so don't use your memory. Use a calendar, and a card that can say no.
