Terms of Use

Updated September 8, 2026 · applies to the Crinkle website and the Crinkle beta app

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.

Crinkle primarily targets customers in the United States. Availability elsewhere depends on the distribution channel and services offered. These terms do not exclude customers solely because they live outside the United States and do not waive mandatory rights under applicable local law.

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 or commercial, 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 do not automatically collect your project content; you may choose to share content with support.

AI output is not guaranteed to be correct, safe, or original. Crinkle verifies its work against the checks it can run, but a passing check or completion status is not a guarantee that a goal is fully satisfied. 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 for local Free-plan use and uses an emailed code or an offered Google or GitHub connection. 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.

6a. Plans, billing, and cancellation

Token allowance. Every plan includes a monthly allowance of AI tokens that Crinkle generates on your behalf, counted across every provider you connect (API keys, local models, and CLI subscriptions, where the count is an estimate). The current allowances and prices are on the pricing page. When an allowance is used up, the app pauses autonomous work until the period resets or you change plan; nothing else stops working. The Unlimited plan has no monthly ceiling but is subject to fair use: we may contact you, throttle, or end service for abuse, unauthorized account sharing, or resale of account access. Ordinary unattended coding runs are an intended use of Crinkle.

Paying. Paid plans are monthly subscriptions billed in advance through Stripe, our payment processor. Stripe collects and stores your payment details under its own terms and privacy policy; we never see your card number. Prices are shown in US dollars and exclude any applicable sales taxes we collect through Stripe for your location.

Renewal and cancellation. Subscriptions renew automatically each month until you cancel. You can cancel, switch plans, or turn off renewal at any time from your account page (Manage plan). Cancelling stops future charges; your plan stays active until the end of the period you already paid for, and then drops to Free. The billing portal shows the effective date and any charges or credits for a plan change before you confirm it. Uninstalling the app does not cancel a subscription. If you cannot access the portal, contact support@crinkle.dev for help cancelling.

Refunds. Because the allowance is available from the moment you pay, subscription fees are non-refundable except where a refund is required by law or where we agree one is fair (for example, a charge made in error or a service failure on our side). Write to support@crinkle.dev with the charge date and account email and we will look at it. Please contact us within 14 days for discretionary requests; this does not shorten any statutory deadline. Access to the allowance does not by itself waive any applicable cancellation, withdrawal, or refund rights.

Failed payments and changes. If a renewal payment fails, Stripe retries it and your plan may drop to Free until it succeeds. We will email you advance notice of material changes, including how to cancel. Fee-change notices will be sent 7–30 days before the change takes effect, or as otherwise required by applicable law. Changes do not apply to an already-paid period. A pricing-page update alone is not notice to an existing subscriber.

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 plan 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 of Georgia, without regard to conflict-of-law rules; disputes are subject to applicable jurisdiction rules. These terms do not remove mandatory protections or rights to bring proceedings in your home jurisdiction where applicable law provides them.

Microsoft Store distribution

Microsoft Store download and installation are also subject to the applicable Store terms. Crinkle subscriptions purchased on crinkle.dev are billed through Stripe and managed through your Crinkle account, separately from Store installation.
