Privacy Policy
1. Introduction
Welcome to the Markdown Meta Tag Tester, a free, open-source, client-side web utility created to help users validate and preview meta tags in Markdown files. We, the developers behind this tool, are deeply committed to user privacy. This Privacy Policy explains our practices clearly and simply.
We collect no personal data whatsoever. The tool runs entirely in your web browser using JavaScript. No information you enter — including your Markdown content, file names, or any other input — is ever sent to us or to any third-party server. This design choice is intentional and fundamental to how the tool operates.
2. Information We Do Not Collect
Because everything happens locally on your device, we do not and cannot collect:
- Personal information such as names, email addresses, IP addresses, or any other identifiers
- Content you input — your Markdown text, meta tags, or previews remain only in your browser's memory
- Usage statistics — we do not track which features you use, how long you stay on the page, or any behavioral data
- Device or browser details beyond what is automatically sent in a standard HTTP request (which we never log or store)
3. How Your Data Stays Private
All processing — parsing YAML front matter, validating required meta fields, rendering previews, and generating export files — occurs exclusively client-side. Your browser's JavaScript engine handles everything. There are:
- No backend servers
- No APIs calls to external services for analytics or processing
- No persistent storage of your input (localStorage or IndexedDB is not used)
Any temporary data (such as your current Markdown while editing) exists only in memory and is discarded when you close or refresh the tab.
4. Third-Party Services and Dependencies
The tool uses a small number of open-source JavaScript libraries (loaded either bundled or via public CDNs). These libraries do not collect data or include tracking code. We do not embed advertising, social media widgets, or analytics scripts of any kind.
5. Cookies and Tracking Technologies
No cookies are set or used. The site is completely stateless. There are no trackers, pixels, beacons, or fingerprinting techniques employed.
6. Security Considerations
While we do not handle your data, security ultimately depends on your device and browser. We recommend:
- Using an up-to-date, secure browser
- Avoiding public or shared computers when working with sensitive Markdown
- Being cautious when sharing exported previews or HTML files
7. Children's Privacy
This tool is not directed to children under 13. We do not knowingly collect or process data from children.
8. Changes to This Policy
We may update this Privacy Policy occasionally. Any changes will be posted here with a new effective date. Continued use of the tool after changes constitutes acceptance.

Thank you for trusting a truly privacy-respecting tool. Your data never leaves your browser.
