1. What you are agreeing to
yangbyte (“we”, “us”) is an independent software project operated as a sole individual venture, reachable at support@yangbyte.com. We build and sell small macOS utilities. These terms cover all software you buy, download, or use through yangbyte.com. Product-specific details are in section 7 and will be extended when we ship new products. By buying, downloading, or using our software, you accept these terms. If you do not agree with any part of them, please do not use our software.
2. License
Once you have paid, we grant you a personal, non-exclusive, non-transferable license to:
- install and use the software you purchased on Macs you own or control;
- keep copies of the software for backup purposes.
You may not:
- resell, rent, lend, or distribute the software or your license key, or publish the key;
- decompile, disassemble, or otherwise attempt to derive the source code, except where the law expressly permits it;
- circumvent, remove, or interfere with license verification;
- use the software for any unlawful purpose.
The software is licensed, not sold. All rights not expressly granted here are reserved.
3. One-time payment and updates
Our software is sold as a one-time purchase: you pay once, keep the major version you bought forever, and receive every subsequent update in that major version (for example 1.x) at no extra cost.
A future major version (2.0, say) may be a paid upgrade. If that happens, we will say so in advance. There is no subscription, nothing auto-renews, and there are no in-app purchases.
4. Purchase and payment
- Mainland China: via Alipay, processed by the third-party payment provider Ma3fu.
- Everywhere else: processed by Creem (Armitage Labs OÜ) as our authorized reseller and Merchant of Record. This means your sale contract is with Creem, receipts are issued by Creem, and local sales tax or VAT is collected and remitted by Creem. International orders are also subject to the Creem Buyer Terms.
The price shown on the page is the price in effect at that time. We may change prices at any time; changes do not affect orders already completed.
5. Delivery and activation
After a successful payment, your license key and a one-click activation link are sent automatically to the email address you entered at checkout, usually within a few minutes.
- The key is paired with that address; activation needs both.
- If nothing arrives within 30 minutes, check your spam folder, then write to support@yangbyte.com and we will resend it.
- Keep that email. It is all you need to reactivate on a new Mac or after a clean install.
6. Refunds
Digital goods cannot really be “returned” once delivered, but if something is wrong, write to support@yangbyte.com first — we will try to sort it out. If the software genuinely will not run on your machine, or you are simply not happy with it, we will refund you.
- Once refunded, the corresponding license key is revoked.
- International orders are refunded by Creem under its Buyer Terms, back to the original payment method; contact us directly and we will start the process for you.
- Statutory withdrawal rights for consumers in the EU are unaffected by this section.
7. Product-specific terms
The following applies only to the named product. System requirements, permissions, and platform limits differ by product — please check before buying.
7.1 Gridly
Gridly requires macOS 14.0 or later, a Mac with Intel or Apple Silicon, a trackpad, and macOS Accessibility permission. Please make sure your setup meets these requirements before buying.
Granting Accessibility permission means Gridly is able to move your windows. Please be sure you understand that before granting it.
macOS does not allow certain windows to be moved or resized at all — some system windows, apps already in full screen, and windows that are not resizable. That is a platform limitation, not a defect in the software.
8. Your responsibilities
You are responsible for keeping the email that contains your license key, and for reading section 7 so you understand the permissions and limits of the product you bought.
9. Intellectual property
Our software and everything in it — code, icons, interface, documentation, names, and marks — belong to us and are protected by copyright and related laws. Buying a license transfers no intellectual property.
10. Disclaimer
To the maximum extent permitted by applicable law, the software is provided “as is” and “as available”, without warranty of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the software will be error-free, uninterrupted, or compatible with every application you run.
11. Limitation of liability
To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential, or punitive damages, and our total aggregate liability is capped at the amount you actually paid for the software.
Some jurisdictions do not allow the exclusion of implied warranties or the limitation of liability, so these limits may not apply to you.
12. Termination
We may terminate your license if you materially breach these terms — for example by distributing your license key or circumventing license verification. On termination you must stop using the software and delete it. Sections 9 to 11 survive termination.
13. Changes to these terms
We may update these terms. When we do, we change the date at the top of this page, and for material changes we notify you at your license email address. Changes do not apply retroactively to orders already completed.
14. Governing law
These terms are governed by the laws of the People’s Republic of China (excluding the Hong Kong SAR, the Macau SAR, and Taiwan). Please raise any dispute with us directly first; if it cannot be settled that way, it may be brought before a competent people’s court of the People’s Republic of China.
If you are buying as a consumer, the mandatory consumer protection laws of your own country still apply and are not affected by this section. For international orders, anything concerning payment, receipts, or refunds is additionally governed by the Creem Buyer Terms.
