Free trial questions
Do I need a credit card to start the free trial?
No. The 7-day trial requires no credit card. We email you a link to activate it, and it never charges you.
What happens when the 7 days are up?
Nothing — the trial simply ends. There's no card on file, so you're never charged. Subscribe if you'd like to keep premium features.

How do I start the trial?
Enter your name and email above, check your inbox for the activation link, and tap it to start your 7-day free trial.
Can I start more than one free trial?
Each email address gets a single 7-day trial. Entering the same address again won't start a second one — if you already have an account or active trial, we'll point you to it. Need a little more time? Just get in touch.
