End User License Agreement (EULA)

mdai — desktop application Last updated: August 10, 2026

This End User License Agreement (“Agreement”) is a legal agreement between you (“you”, “Licensee”) and Goran Jovanović (“Licensor”) for the mdai desktop application, including any updates and documentation (the “Software”). By installing, activating, or using the Software, you agree to this Agreement. If you do not agree, do not install or use the Software.

1. License Grant

Subject to your compliance with this Agreement and, after the trial period, payment of the applicable license fee, the Licensor grants you a personal, non-exclusive, non-transferable license to install and use the Software on up to three (3) devices that you personally own or control.

A purchased license is a perpetual, one-time purchase covering the mdai application and all of its future updates, with no subscription and no expiry. It does not cover separate products or services that may be offered separately in the future.

2. Trial

You may evaluate the full Software free of charge for 15 days from first launch. After the trial expires, editing features are disabled until a license is activated. Your documents are never locked, modified, or made inaccessible by the Software — they remain plain Markdown files on your disk at all times.

3. Restrictions

You may not: (a) redistribute, sell, rent, lease, sublicense, or otherwise transfer the Software or your license key to any third party; (b) reverse engineer, decompile, or disassemble the Software, except to the extent such restriction is prohibited by applicable law; (c) circumvent or attempt to circumvent the license activation or trial mechanism; (d) use the Software to develop a competing product based on the Software’s code.

4. Your Content

The Software is local-first. Your documents are stored as plain files on your own device and remain entirely yours. The Licensor claims no rights over your content and has no access to it.

5. Third-Party AI Providers (BYOK)

The Software’s AI features operate on a “bring your own key” basis: you supply your own API key for a third-party AI provider (e.g. Anthropic, Google, DeepSeek, OpenAI). Your relationship with such providers, including their terms, pricing, and handling of the content you send them, is solely between you and the provider. The Licensor is not a party to that relationship, does not proxy or store your AI traffic, and is not responsible for third-party services. API keys are stored locally in your operating system’s keychain.

6. Purchases, Payment, and Refunds

Purchases are processed by our merchant of record, Paddle, which handles payment, applicable taxes, and license key delivery under its own terms of service. You may request a full refund within 14 days of purchase by contacting us or Paddle; refunds are processed by Paddle as merchant of record.

7. Updates

The Licensor may provide updates at their discretion. Updates are free for the lifetime of the license. The Software does not install updates automatically without your action.

8. Termination

This Agreement terminates automatically if you materially breach it. Upon termination you must stop using the Software and delete all copies. Your documents, being plain files you own, are unaffected. Sections 4, 9, 10, and 11 survive termination. A refund or chargeback of your purchase terminates the associated license.

9. No Warranty

THE SOFTWARE 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 NON-INFRINGEMENT. YOU USE THE SOFTWARE AT YOUR OWN RISK. YOU ARE RESPONSIBLE FOR BACKING UP YOUR DATA.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES (INCLUDING LOSS OF DATA, PROFITS, OR BUSINESS) ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE LICENSOR’S TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE LICENSE.

11. General

This Agreement is the entire agreement between you and the Licensor regarding the Software and supersedes any prior agreements. If any provision is held unenforceable, the remainder stays in effect. Failure to enforce a provision is not a waiver.

Governing law: the laws of Montenegro, without regard to its conflict-of-law rules.
