Markdown to PDF

Privacy Policy

Last updated: May 15, 2026

1. What We Collect

All Markdown-to-PDF, -Word, and -HTML conversion happens inside your browser. Your Markdown content is never sent to our server and we cannot read it.

When you create an account, we store your email address and a record of past conversions (file names, formats, sizes, and timestamps only — never the file content itself).

2. How Conversion Works

HTML is rendered locally with the unified/remark pipeline. Word (.docx) is generated in the browser via the docx package. PDF uses your browser's native print engine (the same engine that "Save as PDF" uses) inside a hidden iframe. In every case, the generated file is created on your device and downloaded directly — no upload, no server round-trip.

3. Data Storage

We use Supabase to host the optional accounts table and the conversion-history log. The only data stored there is what you see on the Dashboard — email and history metadata. Markdown content and generated files are not stored anywhere by us.

4. Cookies

We use two categories of cookies:

  • Essential cookies — set by Supabase to keep you signed in if you choose to create an account. The site works without an account; in that case no essential cookies are set.
  • Advertising cookies — once advertising is enabled (see §5), Google AdSense and its third-party advertising partners may set cookies in your browser to serve and measure ads. While the site is under AdSense review, no advertising scripts are loaded and no advertising cookies are set.

We do not use any first-party analytics product (Google Analytics, Plausible, etc.).

5. Advertising

This site is intended to be supported by advertising delivered by Google AdSense. Google and its third-party vendors may use cookies to serve ads based on a user's prior visits to this site or other websites.

Google's use of advertising cookies (including the DoubleClick cookie) enables it and its partners to serve ads to our users based on their visit to our sites and/or other sites on the Internet. Ads may be personalized (targeted using your interests) or non-personalized (contextual only), depending on your consent and your Google account settings.

You can opt out of personalized advertising at any time by visiting Google Ads Settings. You can also opt out of third-party vendors' use of cookies for personalized ads at aboutads.info.

Current status: the site is still in the AdSense review phase. No advertising code is loaded yet, and no advertising cookies are set in your browser by us or by Google at this time. This page is being kept up to date now so the disclosure is in place when ads do start serving.

Users in the EEA, UK and Switzerland: where required by GDPR and the ePrivacy Directive, we will obtain your consent through a consent management platform (such as Google's Funding Choices) before placing non-essential cookies or showing personalized ads. Ad serving and the consent flow will be enabled together — you will not be shown ads until you have had the opportunity to make a consent choice. You can withdraw consent at any time once the consent banner is live.

For more information on how Google uses data when you use our site, see the Google Partner Sites policy.

6. Third-Party Services

We use the following third-party services:

  • Supabase — authentication and history database (optional, only if you create an account)
  • Vercel — frontend hosting
  • Google — OAuth authentication (optional) and AdSense advertising (see §5)
