Privacy Policy

Learn how Mermaid2Img handles your data and protects your privacy.

Introduction

Mermaid2Img ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you visit https://mermaid2img.com (the "Website"). By using our Website, you agree to the terms outlined in this policy.

Information We Do Not Collect

We prioritize your privacy by design. All diagram rendering, image conversion, and code processing happen entirely within your web browser. We do not collect, store, or transmit any of the following:

  • Mermaid diagram code you enter or paste
  • Generated images or exported files
  • Personal identification information (name, email, address)
  • User accounts or login credentials

Analytics and Performance

We use third-party analytics services to understand how visitors interact with our Website. These services may use cookies and similar technologies to collect anonymous usage data:

  • Google Analytics (G-BQ4EHRKR9G) — helps us understand traffic patterns and user behavior
  • Cloudflare Web Analytics — provides performance metrics and visitor insights

All analytics data is aggregated and anonymized. We cannot identify individual users from this data.

Advertising

We participate in the Google AdSense program to display advertisements on our Website. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to our Website or other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Cookies and Similar Technologies

We use cookies and similar technologies for the following purposes:

  • Essential cookies — required for the Website to function properly (e.g., language preference)
  • Analytics cookies — help us understand how visitors use the Website
  • Advertising cookies — used by Google AdSense to serve relevant ads

You can control cookie preferences through the cookie consent banner displayed on your first visit, or through your browser settings at any time.

Data Security

Since all processing occurs client-side in your browser, your diagram data never leaves your device. We employ industry-standard security measures for our Website infrastructure, including HTTPS encryption for all connections.

Your Rights

Depending on your jurisdiction, you may have the following rights regarding your data:

  • Right to access — request information about data we hold about you
  • Right to deletion — request deletion of any personal data
  • Right to opt-out — decline cookies and tracking technologies
  • Right to complaint — lodge a complaint with a supervisory authority

As we do not collect personal data for diagram processing, most of these rights apply primarily to analytics and advertising data collected by third-party services.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically.
