Hi @leiikun ??
Thank you for taking the time to share your feedback!
We do require a credit card when creating your account; including when registering for the free plan.
We provide controls to determine exactly how and when your account is billed. You can manage these settings within your account preferences, which can be found here:?https://optinmonster.com/docs/pageview-and-upgrade-preferences/.
?
Additionally, we offer a 14-day unconditional money-back guarantee, so if for any reason you’re not completely satisfied with OptinMonster, you can cancel your account and receive a hassle-free refund.
I hope you’ll consider giving OptinMonster another try in the future; but if not we still wish you all the best with the tool or service you decide fits your specific needs and goals. ??
