Privacy Policy
MermaidRender.com is a browser-based Mermaid diagram editor and exporter. This Privacy Policy explains how information is processed when you visit and use our service.
How the service works
The editor runs entirely in your browser. All Mermaid code and diagram data entered into the editor are processed locally on your device to render previews and support export features. We do not transmit or store your diagram designs on our servers.
Information collected automatically
Like most websites, MermaidRender.com and its hosting services may automatically process standard network logging information (such as IP addresses, browser types, referral links, and timestamps) necessary to maintain server security, analyze general usage trends, and maintain site uptime.
Analytics
We use Google Analytics 4 to understand general traffic and visitor engagement in the aggregate. Google Analytics may collect information such as page views, scroll depth, file downloads, and interactions with buttons. This aggregated data does not identify you personally and is used solely to optimize the performance of the service. We do not send your Mermaid code or diagrams to analytics systems.
Advertising
We use Google AdSense to display advertisements. Google and its partners may use cookies, device identifiers, and similar technologies to serve, measure, and personalize ads based on your consent settings. EEA, UK, and Swiss users will see a consent banner to manage advertising preferences.
Cookies and similar technologies
We may use cookies and local storage to store essential preferences (such as your theme setting or templates) and to support consent management tools and advertising features.
Third-party services
This site is hosted and operated using third-party services (such as content delivery networks and hosting providers). These providers process technical information in compliance with their respective privacy terms and security standards.
Your choices
You can manage your cookie preferences at any time through your browser settings or via the consent tools provided on the website.
Data retention and protection
Since we do not collect or store user accounts, diagrams, or personal profiles, we do not retain your design data. Technical server logs are retained temporarily for security auditing purposes.
Children
Our service does not collect personal information from children under 13, and is not designed or targeted for children's use.
