1. Overview and Core Privacy Commitment
MDPreview ("we", "our", or "us") respects your privacy. We are committed to transparency and data minimization. Unlike traditional web services, MDPreview is engineered as a client-side web application. All text, Markdown source code, and documents you view or edit are processed directly within your browser session.
2. Data Collection and Processing
We do NOT collect, transmit, store, or sell the content of your Markdown documents. All parsing and rendering operations happen strictly in local memory. When you drag and drop a file or paste text, it remains isolated on your device.
3. Local Storage
To provide a continuous editing experience, MDPreview uses your browser's localStorage API to temporarily preserve:
- Your most recent editing draft (so your work is not lost upon page reload).
- Your preferred theme selection (e.g., GitHub Light, Dark, Sepia).
- Your preferred layout mode (e.g., Split Screen, Preview Only).
This data never leaves your device and can be cleared at any time via your browser settings or the "Clear" button in the toolbar.
4. Third-Party Advertising and Cookies (Google AdSense)
We may partner with third-party advertising networks, such as Google AdSense, to display non-intrusive advertisements that help fund hosting and ongoing development:
- Google and third-party vendors use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
- Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites.
- Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendor use of cookies by visiting www.aboutads.info.
5. Compliance with GDPR and CCPA
Because we do not store personal identification information or user account records on external servers, your data is inherently protected under global data protection frameworks including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
