Terms of sale and use

Plain terms for a simple purchase.

Last updated October 14, 2026

1. Agreement

These terms are between you and One Trinity Consulting Inc., which makes Perch. By buying or using Perch you agree to them. If you don’t agree, please don’t use Perch.

2. Your license

Your purchase gives you a perpetual, non-exclusive, non-transferable license to use Perch for your own personal or work use on Macs you own or control. It is a one-time payment, not a subscription, and it never renews or charges you again. Source code is not included.

You may not resell, rent, share license keys publicly, or redistribute Perch, and you may not reverse engineer it except where the law allows it.

3. Updates and support

Your purchase includes all updates we release, and email support, for one year from the date of purchase. After that, the version you have keeps working for good. We may offer later versions or extended updates separately, but you are never required to buy them.

4. Requirements

Perch needs a Mac with Apple silicon running macOS 14 or later. Intel Macs are not supported. It works with Claude Code, Codex and Cursor through each agent’s own hooks, and what Perch can show or answer depends on what each agent supports. Agents change over time, and a change on their side can affect a feature until we update Perch. Please check the agent support table on the home page before you buy.

5. Refunds

If Perch isn’t right for you, email support@trillium.one within 14 days of purchase with your order email, and we’ll refund you in full. No questions asked. Refunds go back to your original payment method through Stripe. This doesn’t limit any rights you have under consumer law where you live.

6. Payment and taxes

Prices are in US dollars. Payment is handled by Stripe. The $29 launch price applies to the first 1,000 customers; after that the price is $99. Launch pricing never changes what you already paid. Applicable sales tax or VAT may be added at checkout depending on where you are.

7. Answering your agents

Answering is off until you turn it on. When it’s on, Perch sends an agent only what you click or type, after a two-second window to undo. You are responsible for what you approve, deny or send, just as you would be in the agent’s own window. Read commands and changes before you allow them.

8. Your content

Your projects, prompts, notes and everything your agents produce belong to you. They stay on your Mac, and we never receive them. See the privacy policy.

9. Warranty and liability

Apart from the refund above and any rights you have under law, Perch is provided “as is”, without warranties of any kind. To the extent the law allows, we are not liable for indirect or consequential losses, including the actions of any coding agent, and our total liability for any claim is limited to the amount you paid for Perch.

10. Changes

We may update these terms. Changes apply to future purchases, and they won’t take away a license you have already bought.
