Aphelion — Product and Licensing Facts

These facts are part of the Aphelion Software License Agreement, in the version current on the day you buy. They set out what differs from one product to another. If they ever conflict with the license agreement, the license agreement prevails. Every version of these facts is kept at https://aphelion.music/legal.

1. What these facts cover

This version covers our audio plug-ins Titanframe, Dropforge, Hangar, Turbofan, Gantry and Castframe, which are paid, and Lodestone, which is free.

Our applications, Phonon, Helios and Mothlight, are not on sale yet. Each of them, and any plug-in not listed here, is added to these facts in a new version before it goes on sale.

Our browser tools, Pretzel and Daub, are free, run in your browser and are not licensed under the license agreement. Our terms of service cover them.

2. True of everything we sell

  • Who sells and who licenses. Lemon Squeezy sells our products, as merchant of record. Aphelion LLC d/b/a Aphelion, a Georgia limited liability company, licenses them to you.
  • What you make is yours. Music, audio, presets and anything else you make with our products is yours, royalty-free and with no credit required. That right survives the end of your license, a refund and everything else in section 24 of the license agreement.
  • Updates. Every update to the product you buy is included, whatever its version number. A new edition sold as a separate product under its own name, such as the same name with a "2" added, is a separate purchase, unless you bought within 30 days before it was released.
  • Security updates continue for five years from the first release of each edition. The month and year they end is shown on the product page before you buy.
  • Notices. Each product comes with the notices for the open-source software and the other third-party material in it.

3. Our plug-ins

  • No activation, no license file, no dongle and no server dependency. A plug-in does not use our Licensing Service, never contacts us, and always loads, whatever the state of your license.
  • Sold once. Each paid plug-in here is a one-time purchase that gives you a perpetual license, not a subscription.
  • Formats. VST3 on 64-bit Windows, and VST3 and Audio Unit on macOS, built for both Apple silicon and Intel.
  • What it runs on. 64-bit Windows 11, in any version Microsoft still supports, or macOS 15 or later.
  • A demo first. Every paid plug-in has a free demo, offered before the plug-in goes on sale. The demo has no time limit and no license check, but it interrupts its sound at random, with short silences and with other sounds played over it. You may not release, distribute or make commercial use of anything made with a demo. Free plug-ins have no demo.
  • Content we supply. The patches, presets, kits, grooves and rooms that come with a plug-in, listed in section 5, are ours. You may use them in anything you make, under section 13 of the license agreement.

4. Content made by others

Some content in our plug-ins was made by others, who license it under open licenses. Those licenses govern that content and prevail over the license agreement (section 14 of the license agreement), and the notices that come with each plug-in credit its makers.
