Terms of Use

Effective August 4, 2026 · applies to the Crinkle website and the Crinkle beta app

The short version: Crinkle is free beta software that builds and runs code on your machine, inside boundaries you set. It comes as is, you stay in charge of what it produces and executes, and you own what you build with it. Please read the rest; it is short and written for humans.

1. Who we are, and agreeing to these terms

"Crinkle", "we", and "us" mean the developer and operator of the Crinkle software and the crinkle.dev website. You can reach us at support@crinkle.dev. By using the website, creating an account, or installing the app, you agree to these terms. If you do not agree, please do not use Crinkle.

2. The beta, plainly

Crinkle is pre-release software. Features may change, break, or be removed; runs can fail; updates may require you to reconfigure things. We may suspend or discontinue the beta, or any part of it, at any time. Do not rely on the beta for work you cannot afford to lose, and keep backups of anything important.

3. Your license to use Crinkle

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Crinkle app for building your own software, and to use the website. You may not:

sell, rent, sublicense, or redistribute Crinkle itself;
reverse engineer or decompile it, except where the law expressly permits;
use it to build or operate malware, spam systems, or anything illegal;
use it in a way that abuses the third-party AI services you connect (their terms apply to those calls);
probe, overload, or disrupt the website or our sign-in service.

4. Your projects and AI-generated output

What you build is yours. As between you and us, you own your prompts, your project files, and the code the agents generate in your workspace. We claim no rights over it and, as described in the privacy policy, we never even see it.

AI output is not guaranteed to be correct, safe, or original. Crinkle verifies its work against the checks it can run, and reports honestly, but machine-generated code can still contain bugs, security flaws, or content resembling its training data. You are responsible for reviewing anything you ship, deploy, sell, or rely on, and for making sure your use of generated output complies with the licenses and laws that apply to you.

5. Autonomy and your boundaries

Crinkle's whole point is working unattended: within the boundaries you configure, it writes files in its workspaces, runs allowlisted commands, drives a browser, and calls the AI providers you connected. You choose those boundaries, and you are responsible for them:

Provider costs are yours. The app tracks estimated spend and enforces the caps you set, but your agreements and bills for OpenAI, Anthropic, NVIDIA, or any other provider are between you and them. Estimates can lag or differ from a provider's own metering.
Approvals matter. If you enable auto-approval for file changes, commands, or installs, you are authorizing Crinkle to take those actions without asking each time.
Credentials you give it (API keys, site logins for the web operator) are stored encrypted on your machine and used only as you direct; keeping them valid and authorized is your responsibility.

6. Accounts

Sign-in is optional and uses a code we email you. Keep access to that email address; anyone who controls it can use your Crinkle account. We may suspend accounts used for abuse, fraud, or violations of these terms. You can delete your account and its data at any time as described in the privacy policy.

7. Our stuff

Crinkle's software, name, logo, website, and content are ours and protected by law. These terms give you no rights in them beyond the license above. If you send us feedback or suggestions, you let us use them without restriction or compensation; that is what feedback is for.

8. No warranty

CRINKLE, THE WEBSITE, AND EVERYTHING THEY PRODUCE ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION. Some places do not allow certain warranty exclusions, so parts of this may not apply to you.

9. Limitation of liability

TO THE MAXIMUM EXTENT THE LAW ALLOWS, WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF CRINKLE. This includes the conduct of autonomous runs within the boundaries you configured and the quality of generated code. Our total liability for any claim is limited to the amount you paid us for Crinkle in the past twelve months, which for the free beta is zero. Nothing here limits liability that cannot be limited by law, or your statutory consumer rights where they apply.

10. If there is a problem

You agree to tell us about issues at support@crinkle.dev and give us a reasonable chance to fix them. You will not hold us responsible for claims arising from your own violation of these terms or misuse of the software.

11. Changes and governing law

We may update these terms as the product evolves; material changes will be noted on this page and in release notes, and continued use after a change means you accept it. These terms are governed by the laws of the United States and the state where the operator resides, without regard to conflict-of-law rules; disputes belong in the courts of that state.
