Terms of sale and use
Last updated 14 November 2026
1. Who you're dealing with
Hocus Sync (the application, the Premiere Pro panel, their updates and documentation: the "Software") is made by Clockwork Post Production, LLC ("we", "us"). Contact: support@hocussync.com.
Our order process is conducted by our online reseller Paddle.com. Paddle.com is the merchant of record for all our orders. Paddle handles payment, tax, invoices and order enquiries, and its buyer terms apply to your purchase. These terms cover your use of the Software.
2. Free version
You may use the Software at no charge without a licence key. The free version syncs by waveform and timecode without limit, and syncs by lip movement for up to 3 clips on each Mac.
3. Your licence
When you buy a licence key, we grant you a non-exclusive, non-transferable licence to use the full Software, for commercial and non-commercial work, for one person on up to two Macs that you own or control.
Updates. Your key covers every version we release within six months of your purchase date. Those versions keep working after that period, for as long as they run on your system. Versions released later run as the free version until you renew.
4. What you may not do
- Share, sell, rent or publish your licence key, or use it on more people or Macs than section 3 allows.
- Remove or work around the licence check or the free-version limit.
- Copy or distribute the Software, except to install it as allowed above.
- Use the Software to extract, copy or train on its models, or to build a competing synchronisation product.
5. Reverse engineering
You may not decompile, disassemble or reverse engineer the Software, except where the law where you live allows it regardless of this clause, and except for the open-source components described in section 7, which are governed by their own licences.
6. Your media
The Software analyses your media on your own computer and does not upload it. Our privacy policy explains what the Software does send.
7. Third-party components
The Software includes open-source components, listed with their licences in the notices installed with it. Those licences govern those components and, where they give you more rights than these terms, they prevail. In particular, the LGPL-licensed libraries (including FFmpeg) may be replaced, modified and reverse engineered as their licences allow. Source code for them is available on request at support@hocussync.com.
8. Refunds
You can get a full refund within 30 days of purchase, no questions asked. See the refund policy.
9. No warranty
Synchronisation results are suggestions for you to review before you apply them. Check them before delivering work. To the extent the law allows, the Software is provided "as is", without warranties of any kind.
10. Limitation of liability
To the extent the law allows, our total liability is limited to the amount you paid for your licence, and we are not liable for lost work, missed deadlines, lost profits or indirect damages. Nothing in these terms limits rights you have under consumer law that cannot be excluded.
11. Ending the licence
Your licence ends automatically if you break these terms, or if you are refunded. You must then stop using the full Software and remove your key. Sections 5, 7, 9 and 10 continue to apply.
12. General
If part of these terms is unenforceable, the rest still applies. These terms, with Paddle's buyer terms, are the whole agreement about the Software. We may update them for new versions; the version in place when you got a copy applies to that copy.
