Terms of Use
Last updated: May 2026
Agreement to Terms
By downloading, installing, or using PromptNest ("the Application"), a native macOS application developed by JustOneDev and distributed through the Mac App Store, you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the Application.
Because the Application is delivered through the Mac App Store, your use is also governed by Apple's Licensed Application End User License Agreement. In the event of a conflict between these Terms and Apple's EULA, Apple's EULA controls with respect to the Mac App Store distribution, and these Terms apply to all other matters.
License
PromptNest is licensed, not sold. Upon purchase through the Mac App Store, JustOneDev grants you a limited, non-exclusive, non-transferable license to:
- Download and install the Application on any Mac that you own or control, in accordance with the Mac App Store rules
- Use the Application for personal or commercial purposes
- Receive free updates to the Application via the Mac App Store as they become available
Restrictions
You may not:
- Copy, modify, or distribute the Application
- Reverse engineer, decompile, or disassemble the Application
- Rent, lease, lend, sell, or sublicense the Application
- Use the Application to develop competing products
- Remove or alter any proprietary notices or labels
Your Content
You retain full ownership of all content you create using PromptNest, including prompts, projects, and any other data. Since all data is stored locally on your device, you are solely responsible for:
- Backing up your data
- Securing your device and files
- Ensuring your content complies with applicable laws
Payment and Refunds
PromptNest is available as a one-time purchase through the Mac App Store. There are no subscriptions, recurring charges, or in-app purchases. The purchase price is shown in your local currency on the Mac App Store and may include applicable taxes.
All payments are processed by Apple. Refund requests are handled by Apple under their refund policy. We are unable to issue refunds directly because we never receive your payment information.
Updates
We may release updates to the Application from time to time. These updates may include bug fixes, new features, or security improvements. All updates are delivered free of charge to licensed users through the Mac App Store.
Disclaimer of Warranties
THE APPLICATION IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT.
We do not warrant that the Application will be error-free, uninterrupted, or free of harmful components. You use the Application at your own risk.
Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, JUSTONEDEV SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF THE APPLICATION.
Our total liability for any claims arising from these Terms or your use of the Application shall not exceed the amount you paid for the Application.
Termination
These Terms remain in effect until terminated. Your license to use the Application terminates automatically if you fail to comply with any of these Terms. Upon termination, you must cease all use of the Application and delete all copies from your Mac. Your locally stored prompts and notes remain on your Mac and are not affected by termination.
Changes to Terms
We reserve the right to modify these Terms at any time. Changes will be posted on this page with an updated revision date. Your continued use of the Application after changes constitutes acceptance of the modified Terms.
Governing Law
These Terms shall be governed by and construed in accordance with applicable laws, without regard to conflict of law principles.
