Terms of Service & License Agreement

1. Who you're dealing with

Crispdown is developed by an independent developer. Purchases are direct payments through PayPal and are verified by PayPal's server notification before a Key is issued. PayPal's terms apply to the payment transaction.

2. Free features

The Markdown viewing features of the Software are free of charge for personal and commercial use. You may not sell, sublicense, or redistribute the Software itself, or misrepresent it as your own work.

3. Pro license (EULA)

When you buy Crispdown Pro ($14.99 one-time), you receive a personal, non-exclusive, non-transferable license to use the paid features, under these terms. A temporary launch offer may be shown only when its end condition is stated on the checkout page.

• One person, up to 5 devices. The license covers you, on up to 5 devices that you personally use (for example: work laptop, home desktop, and so on). It is not a floating seat for a team — teammates need their own licenses.
• One Key. New licenses activate with the Key alone. The purchase email and provider transaction ID may be used to verify a manual recovery or refund request; older CD1 licenses remain email-bound for compatibility.
• Don't share the key. Publishing, reselling, or distributing your license key is a breach of this license and leads to revocation (see §6).

4. "Pay once, use v3 forever" — precisely

• Your one-time payment includes all v3 updates and security fixes, forever. No recurring charges, no expiry, no re-validation over the network — activation and verification are fully offline.
• If a major version 4 is ever released, upgrading will be an optional, separate purchase at 50% off for existing license holders. If you never upgrade, your v3 license and every v3 feature keep working unchanged.
• "Forever" means the Software will never disable itself. Ongoing development, however, is provided on a best-effort basis by a solo developer and is not a contractual service guarantee.

5. Refunds

Every purchase carries a 14-day money-back guarantee, no questions asked — see the Refund Policy for the exact process. Statutory consumer rights in your country remain unaffected.

6. Revocation

License keys belonging to refunded or charged-back orders, and keys that have been publicly shared or resold, may be revoked. Revoked keys stop being accepted in subsequent Software updates. Revocation for refunds is a normal part of the guarantee, not a penalty.

7. Acceptable use

You may not: circumvent or tamper with the license mechanism; extract and redistribute the paid features; use the Software to violate any law; or resell the Software or keys. You may inspect the Software's behavior (it's your computer), and honest security research reported to [email protected] is welcome.

8. Third-party components

The Software includes open-source components (such as Markdown, math, diagram, and document libraries) under their respective licenses; the full list ships inside the extension package as THIRD-PARTY-LICENSES. Those licenses govern those components.

9. Warranty disclaimer

The Software is provided "as is", without warranty of any kind, express or implied, including fitness for a particular purpose. I don't warrant that every Markdown document will convert perfectly to every format — where conversion falls short, unsupported content degrades to plain text rather than failing. Nothing in this section excludes warranties that cannot be excluded under your local law.

10. Limitation of liability

To the maximum extent permitted by law, total liability arising from these terms or the Software is limited to the amount you paid for your license. I'm not liable for indirect or consequential damages, or for loss of data caused by third-party software or hardware. Nothing here limits liability that cannot legally be limited.

11. Changes to these terms

These terms may be updated as the product evolves; the current version always lives at this page with the date above. Changes never apply retroactively to rights you've already paid for — your v3 rights cannot be amended away.
