Terms of Service

Acceptance

By installing the Wystan GitHub App, creating an account, or otherwise using Wystan (the "Service"), you agree to these Terms. If you use the Service on behalf of an organization, you represent that you are authorized to bind that organization, and "you" refers to that organization.

The Service

Wystan analyzes repositories you connect, builds a map of features and flows, scores risk and test coverage, and surfaces that insight through pull-request comments, a web dashboard, and an MCP endpoint for AI agents. Features, metrics, and integrations may change over time.

Accounts & organizations

You are responsible for your account, your team members' access, and all activity under your organization. Keep your credentials and API keys secure. Notify us promptly of any unauthorized use.

GitHub App & authorization

To analyze your repositories you install the Wystan GitHub App and grant it the permissions shown on the consent screen (repository contents read-only, pull-request read & write, and metadata). By installing, you authorize us to access and process the repositories you select for the purposes of providing the Service. You may uninstall the App or remove repositories at any time from your GitHub settings; doing so stops further processing.

Your content & ownership

You retain all rights to your code and data ("Customer Data"). You grant us a limited license to access and process Customer Data solely to provide and improve the Service for you. We do not claim ownership of your code, and we do not use your repository content to train machine-learning models. How we store and protect Customer Data is described in our Privacy Policy and Security page; notably, source code is not persisted at rest.

Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of GitHub's or any third party's terms.
• Connect repositories you do not have the right to analyze.
• Attempt to disrupt, reverse-engineer, or gain unauthorized access to the Service or its infrastructure.
• Resell or provide the Service to third parties except as expressly permitted.

Third-party services

The Service integrates with third parties you choose to connect — including GitHub, your LLM provider (Claude, OpenAI, or local Ollama), and optionally Sentry and PostHog. Your use of those services is governed by their own terms. We are not responsible for third-party services.

Plans, billing & free scan

Some features require a paid plan. Paid plans are sold and processed by our merchant of record, Lemon Squeezy, which handles payment and applicable taxes (e.g. VAT). Subscriptions renew automatically for the billing period you select until cancelled. Fees are non-refundable except where required by law. We run your first scan at no charge; plan limits and pricing are described on the Pricing page and may change with notice for future billing periods.

Beta features & open source

Some features may be offered as beta or preview and are provided "as is", without warranty, and may change or be withdrawn. The Wystan analysis engine is available under its open-source license; that license governs your use of the engine itself, separately from these Terms which govern the hosted Service.

Intellectual property

The Service, including its software, design, and trademarks, is owned by Wystan and its licensors. These Terms grant you no rights to our intellectual property except the limited right to use the Service.

Disclaimers

The Service is provided "as is" and "as available". Wystan is an analysis aid — its outputs (feature maps, risk scores, coverage estimates) are informational and may be incomplete or inaccurate. You are responsible for your own engineering decisions. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

Limitation of liability

To the maximum extent permitted by law, Wystan will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or revenue. Our total liability for any claim arising out of or relating to the Service will not exceed the amounts you paid us in the twelve months preceding the claim.

Indemnification

You agree to indemnify and hold Wystan harmless from claims arising out of your Customer Data, your use of the Service, or your violation of these Terms or applicable law.

Term & termination

You may stop using the Service and uninstall the GitHub App at any time. We may suspend or terminate access for violation of these Terms or to protect the Service. On termination, your right to use the Service ends and your data is handled per the retention terms in our Privacy Policy.

Changes to these Terms

We may update these Terms as the product evolves. Material changes will be announced in-product or by email, and the "Last updated" date above will change. Continued use after an update means you accept the revised Terms.

Governing law

These Terms are governed by the laws of the jurisdiction in which Wystan is established, without regard to conflict-of-laws rules. (Jurisdiction to be finalized before publishing.)
