The license you're buying.
PDF OPUS is sold as a perpetual, non‑exclusive license to use the application on up to two Macs that you own or control. You can transfer the license to a different Mac at any time by deactivating one of your existing devices in the dashboard.
What's included.
Every feature in the app today, plus every feature we ship in the future. No paid upgrades. No upgrade tier. The optional AI add‑on is a separate, monthly subscription that you can cancel at any time without losing access to any non‑AI tool.
Refunds.
For 14 days from your purchase date, write to hello@pdfopus.app and we'll refund you in full, no questions. After 14 days, refunds are at our discretion. Lemon Squeezy (our merchant of record) processes the refund within 5–10 business days.
What you can't do.
You can't redistribute the application binary, share your license key, reverse engineer the app, or use it to process documents on behalf of third parties as a hosted service. You can use it for any commercial purpose on your own Mac.
No warranties.
PDF OPUS is provided as‑is. We do our best to ship a tool that's faster, smaller, and more reliable than the alternatives, but we can't promise it will never crash on a particular file. Always keep a backup of any document you care about.
