Four steps, one payment
Pro is bought from inside the app, not from this website — so the licence lands on the computer you are actually using.
-
01
Download and install
Pick your platform on the download page — Windows installer or macOS DMG. Around 2 MB, installed in seconds.
-
02
Try Pro on your own files
Every install starts with 100 full-featured opens — Mermaid, math, both editors, on your own documents. When they run out the app asks; choosing "Maybe Later" keeps everything working.
-
03
Pay inside the app
Open any Markdown file, press Buy Pro in the bottom bar, then Pay with Card. The card page is hosted by Creem, our payment provider — your card details never reach mdview.
-
04
Unlocked on the spot
That computer unlocks as soon as the payment is confirmed — no key to copy, no second launch. Reinstalling the app or moving to a new computer uses the activation code in your order email.
The fine print, in plain words
- ·Prices are in US dollars. Any sales tax or VAT that applies is handled at checkout by our payment provider.
- ·Pro is a one-time payment per computer: no subscription, nothing auto-renews, and Pro updates are included for the life of the app. A price change would only ever apply to future purchases.
- ·Every Pro purchase includes a 14-day money-back guarantee — a full refund within 14 days, no questions asked. The Refund Policy has the details.
- ·The purchase is covered by our Terms of Service; what we do with data is in the Privacy Policy.
