End User License Agreement

Last updated: November 2, 2026

This is the agreement you accept when you install CortexDJ. The app ships the same text as EULA.txt; if the two ever differ, this published version governs.

Who you are dealing with

CortexDJ is developed and licensed by Toma Tomov (“the Licensor”, “we”, “us”). This agreement is between you and the Licensor. Purchases are made through Lemon Squeezy, which is the merchant of record: Lemon Squeezy sells and charges for your order and handles payment, taxes, invoices and refunds under its own buyer terms. The license to use the Software is granted by the Licensor under this agreement.

1. License

CortexDJ (“the Software”) is licensed, not sold. Subject to these terms (and, for paid plans, payment), you receive a non-exclusive, non-transferable license, personal to you, to install and use it on computers you own or control.

2. Activation and computers

The Software builds your first set without a key. Every set after that is unlocked with a license key: a free key, sent when you request one with your e-mail address, or a Pro / Lifetime key on purchase. Every key (free or paid) may be activated on up to two (2) computers at the same time. Reinstalling or updating on an already-activated computer does not use an extra slot; to move to a new computer, contact support@cortexdj.com and we will free a slot. There is no time-limited trial. You may not share, resell or publish your key.

3. Editions

The Free edition is free forever for personal use and includes analysis, the AI auto-mix and mashups, the library, the live decks, and rendering mixes to a file. Pro (subscription) and Lifetime (one-time) additionally unlock MIDI controller support, recording (audio and video), live-streaming and publishing mixes to connected platforms, Stream DJ mode (hours of music that the AI plans and mixes on its own), plus priority support, and may also be used for paid and public performances, such as gigs, venues and events. The rights to the music in any performance, recording or stream remain yours to obtain (section 5). Lifetime purchases include a 30-day money-back guarantee; subscription refunds follow Lemon Squeezy’s terms as merchant of record.

4. Restrictions

You may not: (a) reverse engineer, decompile or circumvent the license mechanism except as permitted by law; (b) redistribute the Software; (c) use it to infringe third-party rights, including by mixing, recording, streaming or distributing audio or video you are not licensed to use.

5. Your content

You are solely responsible for the music and media you load, mix, record and broadcast, and for obtaining all necessary rights and licenses (publishing, performance, mechanical, sync and platform rights) for any public performance, recording or live stream you create with the Software.

6. Third-party software

The Software includes third-party components under their own licenses (see THIRD_PARTY_NOTICES.txt in the app), including FFmpeg. Your use of those components is subject to those licenses.

7. No warranty

THE SOFTWARE IS PROVIDED “AS IS” WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, OR LOSS OF DATA, PROFITS OR GIGS, ARISING FROM USE OF THE SOFTWARE.

9. Termination

This license terminates automatically if you breach it. On termination you must stop using and remove the Software.

10. Governing law

This agreement is governed by the laws of the United States and the state of the Licensor’s principal place of business; mandatory consumer-protection rules of your country of residence remain unaffected.
