License Agreement

Trial Period

ONYX OFX offers a free 7-day trial with full functionality. By purchasing the plugin, you confirm that you have tested it during the trial period and accept its performance, compatibility, and limitations.

License Grant

• Licenses are node-locked: one activation per machine
• 1, 3 or 10 machines depending on the license purchased (Indie, Studio 3, Studio 10)
• Seats are counted per machine, not per artist
• A seat may be moved to another machine — deactivate it on the old one first
• Seats may not be moved between machines automatically
• The license is granted to one individual or one company, and may not be sold, given or transferred to anyone else
• Seats cover the machines the work is done on — your own, your staff's, and those of freelancers and contractors working under your direction on work you produce
• Where the machine stands and who owns it does not matter: a home station, a remote desktop into your office, a laptop on the road, a rented or cloud workstation, a render-farm node, or a machine at your client's facility are all normal use, as long as the seat count is respected
• Each virtual machine counts as one machine
• Batch and overnight rendering of work you produce, including on a render farm, is normal use — each machine needs a seat
• The plugin loads as an OFX plugin in a host application. The hosts we test and support are listed on our site; other OFX hosts are unsupported, not prohibited
• Activation sends machine-specific data to our licensing provider, used to bind and verify the license
• Commercial and non-commercial projects, including client deliverables - no royalty or revenue share payable to ONYX OFX. Receiving material from a client and delivering finished mattes, shots or sequences as part of work you produce is normal use
• ONYX OFX claims no ownership of the mattes and images you produce, and makes no representation as to what the third-party licenses below permit for any particular use
• Perpetual license (no subscription)
• Free updates within v3.x; major versions (v4.0+) may require a discounted upgrade
• Email support included

Pricing

Current pricing is displayed on the payment platform at the time of purchase. Prices may change without notice. Promotional discounts may apply.

Refund Policy

Refunds are granted at ONYX OFX's discretion. A free 7-day trial with full functionality is provided so you can test the plugin before buying, and we do not normally refund for compatibility issues, performance concerns or a change of mind. If something is genuinely wrong, write to support@onyxofx.com and we will look at it case by case.

Disclaimer of Warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. Since you had 7 days to test the plugin before purchase, you accept full responsibility for evaluating its suitability for your needs.

We do not guarantee compatibility with all systems, configurations, or third-party software.

Limitation of Liability

IN NO EVENT SHALL ONYX OFX, ITS DEVELOPERS, OR AFFILIATES BE LIABLE FOR ANY DAMAGES (INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, OR BUSINESS INTERRUPTION) ARISING FROM THE USE OF THE SOFTWARE.

By purchasing after the trial period, you acknowledge that you tested the plugin and accept all risks associated with its use. Maximum liability is limited to the amount paid for the license.

Prohibited Use

• No redistribution, resale, lending, rental, lease, sublicensing, timesharing or service bureau use of the plugin
• No selling, giving or transferring your license to anyone else
• No giving anyone outside your organisation access to the plugin or to its features, by any means
• No offering matte processing by the plugin as a service to others — a queue, a watch folder, a web page, an API, or a price quoted per frame, minute or job of processing
• No accessing the plugin by any means other than as an OFX plugin loaded by a host application through its normal plugin interface, and no embedding it in, or driving it from, any other program or service you make available to others
• No working around activation or machine binding, including cloning or duplicating an activated machine
• No sharing your license key outside your organisation
• You are responsible for everyone you allow to use the plugin, as if their acts were your own
• No reverse engineering or modification, except where applicable law does not allow this restriction
• No use that breaks the law

Termination

We reserve the right to terminate your license if you violate these terms. No refund will be provided upon termination.

Governing Law

This agreement is governed by the laws of Bulgaria. Any disputes shall be resolved in the courts of Varna, Bulgaria.
