Frequently asked questions
Straight answers about proofs, bundles, and how Sapien billing works.
What happens when I exceed 5 proofs on the free plan?
Purchase a bundle whenever you need more. Bundles are one-time purchases that never expire, so you can buy them in advance or only when you need them.
Can I use Sapien without creating proofs?
Absolutely. The editor is available to everyone. Proofs are generated only when you ask for a verified certificate.
How do bundles work?
Each bundle adds a fixed number of proofs to your account. They stack, never expire, and include priority support plus every feature in the free tier.
Is there a maximum number of proofs I can create?
No maximum. Add as many bundles as you need and create proofs for every project, client, or submission.
Can I cancel anytime?
There are no subscriptions to cancel. Your free tier remains active, and purchased bundles stay available until you use them.
