Privacy Policy
1. Our Commitment to Privacy
The Client-Side Markdown Link Checker is built on a fundamental principle: your content never leaves your device. This tool performs all parsing, link extraction, and HTTP validation directly inside your web browser using standard JavaScript APIs. Because no data is transmitted to any server — ours or anyone else’s — we do not collect, store, log, or process any personal information or document content whatsoever.
2. Information We Do Not Collect
We deliberately design the tool to be zero-data. This means we do not obtain:
- Any personal identifiable information (name, email, IP address, device ID, location)
- Any content you paste, upload, or generate (Markdown text, links, file names)
- Any usage analytics (page views, session duration, click events)
- Any browser fingerprinting or tracking signals
Everything you input is processed transiently in memory and discarded when you close the tab or refresh the page. No persistent storage (localStorage, IndexedDB, cookies) is used beyond what your browser may temporarily cache for performance.
3. How the Tool Operates
When you paste Markdown or upload a file:
- The text is parsed locally using browser-native JavaScript.
- Links are identified and tested via the fetch API with HEAD or GET requests sent directly from your device.
- Results are displayed in real time — still entirely in-browser.
- Any export (CSV, JSON) or copy-to-clipboard action uses only client-side APIs.
No part of this workflow involves our servers, third-party endpoints, or telemetry services.
4. Third Parties & External Requests
The only outbound network activity comes from your browser when it tests the links present in your Markdown. We do not embed analytics scripts, advertising pixels, social media trackers, or CDNs that log requests. Open-source libraries (if any) are either bundled or loaded from trusted public sources without tracking parameters.
5. Cookies & Similar Technologies
We use no cookies, no web beacons, no local storage for tracking purposes, and no session identifiers. The application is completely stateless from our perspective.
6. Security of Your Data
Because we never receive your data, the primary security consideration is on your device:
- Keep your browser updated to protect against known vulnerabilities.
- Avoid running the tool on shared or untrusted computers if your Markdown contains sensitive information.
- Use incognito/private mode if you want to ensure nothing is cached.
7. Children’s Privacy
The tool is not directed to children under 13 and does not knowingly collect any information from them. As no data is collected from any user, this provision is precautionary.
8. International Data Considerations
Since no personal data or content is transferred to us or any processor, the tool complies by design with major privacy frameworks including GDPR, CCPA/CPRA, PIPEDA, and similar regulations.
9. Changes to This Policy
We may revise this Privacy Policy to reflect changes in the tool or legal requirements. Any update will be posted here with a new effective date. Continued use after changes constitutes acceptance.
By using the Client-Side Markdown Link Checker you acknowledge and agree that your privacy is protected through our strict no-collection architecture. Your content stays yours — always.
