This End User License Agreement (“EULA”) is between you and The Whimsy and Wizardry Limited Company (“we,” “us”) and governs your use of the Vellerune desktop application (the “Software”). By installing or using the Software, you agree to these terms.
1. License grant
We grant you a non-exclusive, non-transferable, revocable license to install and use the Software on devices you own or control, for your personal or business writing work, subject to these terms. The license is per platform: a license purchased for macOS does not entitle you to run the Software on Windows or Linux, and vice versa.
2. Lifetime updates
Your license includes all future updates and major versions for the platform on which it was purchased, with no additional fee, for as long as we continue to develop the Software for that platform.
3. Restrictions
You may not: (a) reverse engineer, decompile, or disassemble the Software except as expressly permitted by applicable law; (b) sublicense, sell, rent, or lease the Software; (c) remove or obscure proprietary notices; (d) circumvent any license enforcement mechanism.
4. Trial (Windows / Linux)
The Windows and Linux builds offer a 30-day free trial of actual use. The trial includes every feature, including export. The trial counter is stored locally and does not transmit usage data. When the trial ends, the Software requires a license key to continue beyond a read-only / export-only mode.
5. License keys
When you purchase a license for Windows or Linux, you receive a license key from our merchant of record. Activating that key in the Software unlocks it. The Software performs a passive license check approximately every 15 days; if your machine is offline at that time, the check fails silently and the Software continues to work.
6. Your content
The Software is a tool for creating your own writing. You retain all rights to the worlds, characters, books, and other content you create with the Software. We do not access, analyze, transmit, or have any claim to your content.
7. Privacy
The Software's network behavior is described in our Privacy Policy. In short: macOS makes no network calls of its own; Windows and Linux make a once-weekly update check and a once-every-15-days license check, neither of which sends personal data.
8. Disclaimer of warranty
The Software is provided “AS IS” and “AS AVAILABLE,” without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Software will be uninterrupted, error-free, or that defects will be corrected.
Backups are your responsibility. The Software writes locally and includes scene-level snapshots and book-level drafts as built-in safety nets, but it is not a substitute for a backup strategy. The Software's Backup action lets you save a copy of any world to a location of your choice; we recommend keeping those backups on an external drive or in a cloud-synced folder.
9. Limitation of liability
To the maximum extent permitted by law, our aggregate liability arising out of or relating to your use of the Software is limited to the amount you paid for the license, or $100, whichever is greater. In no event are we liable for any indirect, incidental, consequential, or punitive damages, including loss of data, loss of profits, or loss of goodwill, even if we have been advised of the possibility of such damages.
10. Termination
This license is effective until terminated. It terminates automatically without notice if you fail to comply with these terms. Upon termination, you must stop using the Software and delete all copies. The provisions of sections 3, 6, 8, 9, and 12 survive termination.
11. Refunds
Mac purchases are subject to Apple's refund policy. Windows and Linux purchases are subject to our payment processor's standard refund policy; the specific terms will be linked here once that integration is finalized. A 30-day free trial is provided so you can evaluate the Software before purchasing.
12. Governing law
This EULA is governed by the laws of the State of Missouri, USA, without regard to conflict-of-laws principles.
13. Changes
Material changes to this EULA bump the effective date at the top of the page and are listed here, newest first. Continued use of the Software after the effective date constitutes acceptance.
