Frequently asked questions

What's your refund policy?

Pro is backed by a 14-day money-back guarantee — request a refund within 14 days of your first charge and we'll refund the full amount, no questions asked. After day 14, you can still cancel anytime from /settings: access continues through the end of your current billing period and you won't be charged again. See the full Refund Policy.

How do I cancel my subscription?

Cancel from your account's /settings page in one click. Cancellation takes effect at the end of your current billing period — no further charges, no follow-up emails, no support ticket needed. You'll keep Pro access until that date.

What happens to my existing conversions when I upgrade?

Nothing needs to migrate. Nominal runs 100% client-side — your files never leave your browser, so there are no server-side conversions to import. Conversion history and saved presets are Pro-only and start fresh the moment you upgrade.

What's included in Pro?

Unlimited conversions per day (no 2/day cap), 30 days of conversion history, saved presets for common schemas you can reuse on the next file, batch mode to convert multiple files at once, and priority support with replies within 1 business day.

What payment methods do you accept?

All payments go through Stripe Checkout. Cards accepted: Visa, Mastercard, American Express, and Discover. Apple Pay and Google Pay appear automatically when supported by your device. We don't accept PayPal or cryptocurrency at this time.

Do you offer team or business plans?

Not yet — Pro is per-account only and one user per subscription. If you need team licensing, seat-based pricing, or invoicing, email support@nominal.app and we'll let you know when business plans ship.
