Yes of course! There’s a 7-Day Free Trial so you can sign-up, see how it works and try it. If you don’t want to continue you can easily cancel at any time.
And/or, you can pay for one month, try it and see how it goes at the end of that time.
You can always cancel at any time and it’s straightforward to do that on Patreon.
You also have the flexibility to change Tiers at any time if that fits better, or if you have a busy/lean month and want to pay less while staying connected.
