FAQ

Questions, answered

Is there one subscription for all tools?

No. Each tool is a separate plan, so you only pay for what you actually use. Pick one tool, or several.

How does the yearly plan work?

You pay for 10 months and get 12. The yearly price is charged once and renews after a year unless you cancel.

What if I want a refund?

Email info@captainlab.dev within 20 days of purchase with your order number. We refund to the original payment method within 7 days. Details are in our Refund Policy.

Can I switch from monthly to yearly later?

Yes. Switch at any time from the tool's account page; the remaining monthly balance is credited toward the yearly plan.

Do you offer team or volume pricing?

For five or more seats write to us at info@captainlab.dev and we will put together a quote.
