Purchase Fission

Our single-user licenses provide access to the software on one or more personally owned machines. Each user needs just one single-user license, regardless of how many machines the software will be used on.

For shared-use environments such as a lab or library, the software can instead be unlocked on a per-machine basis. In these environments, each shared machine would need one license for the software.

For more details, please see this page.

We believe that no customer should have to buy software in order to find out how well it works. Thus, our software can be fully evaluated prior to purchase and customers are strongly encouraged to take advantage of these free trials. You may also seek any needed technical support from us - we answer support emails rapidly and responsively for current and potential customers alike.

If you desire a refund, please contact us within 14 days of your purchase. As we can not recover the license key, refunds are issued on a case-by-case basis.

Our privacy policy can be summed up with one simple and straight-forward sentence: We don't sell or rent any of your data to third parties, ever, period.

Our payment processor (Paddle) is required to collect taxes in many regions. Local taxes may thus be added to the base item price.

All charges are made in US dollars.

Prior to finalizing your purchase, you will be shown the exact amount that will be charged.
