BETA is for free
Currently NeutrinoParticles project is in public BETA testing phase. And until it is finished you have 100 exports per day for free. If you need to export more effects you need to buy and use Export Packs as described below.
Export 100 effects for $1
Each Export Pack allows you to export 100 effects per day. So if you started export effects, you activated one Export Pack by that, and you have 24 hours to make up to 100 exports.
One Export Pack costs $1. And there are discounts when you buy more packs at once.
Information about Export Packs available for your account you can find at Export Profile page, after sign in.
