All accounts on Polygonia are free. You can sign up and create as many designs as you like. Your designs are stored in the cloud. No credit card is required.
Each month you can download up to three designs for free.
If you need to download more than three designs in a month, then you can look for a promo code. Promo codes give you two months of complimentary Hobbyist subscription, which come with 20 downloads in a month. You can use one promo code per year (that is, per 12 month period).
If you are doing a project that uses Polygonia and you are going to post a video online to show how you used Polygonia in your work and you need more downloads, then please email me.
If you need more downloads or want access to extra features, then you can subscribe. You can cancel at any time.
