Good to Know

Clear from Day One.

A few answers before you start.

Talk to Us
What happens after 30 days?

Your trial ends and design access pauses. Subscribe for $50 USD/month to continue. Your saved projects remain associated with your account; trial expiry does not delete them.

Will I be charged automatically?

No. This trial requires no payment card. You choose whether to subscribe after it ends. Once you subscribe, your plan renews monthly until you cancel.

Are all features included?

Yes. The trial and subscription include every available MEPFlow feature. There are no separate module upgrades. Review the published methods and scope for each module.

Can I cancel my subscription?

Yes. Open Billing in your account to cancel future renewals. You keep access until the end of the period you have paid for.

What if I already have a free account?

Existing free users keep their free access. The 30-day trial and $50 USD/month price apply to new accounts after this pricing launches.

Are the public calculators still free?

Yes. Public calculators, guides and sample resources remain free without an account. The subscription is for the MEPFlow design workspace.
