Frequently Asked Questions
What is included in a license?
Every license includes full access to all features for that product. Each product is licensed separately. Free updates and priority email support are included for the duration of your license term.
Do you offer volume discounts?
Pricing is the same per seat at any quantity, so a team of ten pays ten times the single-seat price. For larger teams we are happy to discuss terms — contact us and we will put together a quote. All seats are managed under a single license key, and you can add seats to an existing license at any time from your dashboard, with subscription proration applied automatically.
Do you offer a free trial?
Yes. Every new account gets a 7-day free trial with full access to all features. No credit card is required to start.
Can I switch between annual and 3-year billing?
Yes. You can upgrade from annual to 3-year billing at any time. Contact support and we will prorate the remaining balance on your current plan.
What is your refund policy?
We offer a 30-day money-back guarantee on all plans. If you are not satisfied within 30 days of purchase, contact support for a full refund.
