Privacy Policy

The Constraint ("we," "our," or "us") respects your privacy. This Privacy Policy explains what information we may collect when you visit theconstraint.io (the "Site"), how we use it, and the choices available to you.

By using the Site, you acknowledge this policy. If you do not agree, please discontinue use of the Site.

Depending on how you interact with the Site, we may collect:

• Technical data such as browser type, device type, operating system, and approximate region derived from IP address.
• Usage data such as pages viewed, referring URLs, timestamps, and diagnostics that help us understand performance and errors.
• Information you voluntarily submit (for example, if you contact us by email or through a form), including the content of your message and your contact details.
• Cookies and similar technologies (see Cookies below).

If you create or access an account using "Sign in with Google" (or an equivalent Google sign-in button), authentication is handled by Google LLC through Google OAuth / Google Identity Services. Google’s screens collect your credentials; we do not receive your Google password.

Subject to the permissions you grant on Google’s consent screen, we may receive data such as a stable Google user identifier, your name, email address, profile picture URL, and basic account flags (for example, whether your email appears verified to Google). We use this information to register and authenticate you, secure your account, send service-related communications when appropriate, and detect abuse.

Google processes personal data under its own policies. You can learn how Google uses data at https://policies.google.com/privacy and manage or revoke third-party access to your Google account in your Google Account security settings. Where we store or combine Google-provided data with other profile or usage data, we treat it as described in the sections above.

We use the information above to operate, secure, and improve the Site; to understand aggregate audience patterns; to respond to inquiries; and to comply with law or protect rights and safety.

We do not sell your personal information. We do not use your data to train general-purpose AI models solely from your visit to this policy page; if other services (such as embedded tools or third-party links) apply different rules, their respective policies govern those interactions.

We may use cookies or similar technologies for essential functionality, preferences, or analytics. You can control many cookies through your browser settings. Disabling cookies may affect certain Site features.

Where we use third-party analytics or error reporting, those providers may process limited technical data according to their own privacy policies.

We may share information with vendors who assist us in hosting, analytics, security, or communications, subject to appropriate safeguards. We may also disclose information if required by law, regulation, legal process, or to protect the rights, property, or safety of our users or the public.

We retain information only as long as reasonably necessary for the purposes described here and as required by law. No method of transmission over the internet is completely secure; we employ reasonable measures designed to protect the information we hold.

Depending on your location, you may have rights regarding access, correction, deletion, objection, or portability of personal data. To exercise applicable rights, contact us using the details published on the Site or in communications you receive from us.

We may update this Privacy Policy from time to time. The revised version will be indicated by an updated "Last updated" date at the top of this page. Continued use of the Site after changes constitutes acceptance of the updated policy.
