FAQ

Pricing questions

Read the refund policy.

Can I cancel anytime?

Pro is billed monthly or annually. Use the billing controls available for your account to cancel future renewal; paid access normally continues through the current paid period. Browser-local and cloud circuit access then follows each lab’s persistence rules and the current Free limits, so create a supported independent copy before entitlement changes where possible.

What exactly is the Founder offer?

It is a $99 one-time purchase with no recurring fee for the same paid feature set as Pro, subject to the service terms. Availability is shown at checkout. Start checkout by December 31, 2026 at 23:59:59 UTC. Checkouts opened before the deadline can finish within their payment window. Existing Founder access continues under its terms.

I bought a one-time tier before. What happens?

Your prior-purchase access remains recognized. You are not moved to a new subscription, and access continues under the applicable terms.

Is there an academic discount?

Yes. Individual students and educators can receive 50% off Pro and the Founder offer while it is available. The automatic check uses a supported school or university email address on your DigiSim account. You do not need to apply on behalf of an institution. Classroom is a separate institutional offer.
