Privacy Policy

How the eight Adoneinu tools collect, temporarily process, and secure what you send.

Last updated:

1. Introduction

This policy covers the Adoneinu website and its eight tools: MD Converter, MD Publisher, MD Reverse, MD Slides, MD Clip, MD Diagram, MD Diff, and Adoneinu SEO Analyzer. They share one account. They do not all handle content the same way. Section 4.1 describes each tool.

2. Information We Collect

2.1 Content You Upload

What you send depends on the tool.

  • MD Converter: Markdown you upload or paste, used to build a preview and an HTML, DOCX, or PDF export.
  • MD Publisher: The Markdown used for SEO fields and a social image.
  • MD Reverse: HTML, plain text, or an uploaded DOCX or PDF, used to extract Markdown.
  • MD Slides: The outline used to build a PDF or PowerPoint deck.
  • MD Clip: A public web address, which our server fetches, or HTML or email text you paste.
  • MD Diagram: A description or Mermaid source used to draft a flowchart and, if you download one, a PNG.
  • MD Diff: Both drafts, sent so the server can compare them.
  • Adoneinu SEO Analyzer: The public domain you enter, fetched so the server can audit that page. Private addresses are refused.

Section 4.1 says what happens to each of those after you send it. We collect and temporarily process:

  • Content you submit: Files, pasted text, public pages, and email text are sent so the tool can do the job you asked for.
  • Generated content: Exports are built for the download. They are not kept as a document library.

Important: We do not use your documents to train models, and we do not sell them. Payment, sign-in, email, fonts, and optional analytics use the services in section 6. Those services do not receive a copy of your document library, because there is not one.

2.2 Automatically Collected Information

When you visit any of these tools, we automatically collect certain technical information:

  • Device and browser information: Browser type, version, and operating system.
  • Usage data: Pages visited, features used, and interaction patterns.
  • IP address: Used for security purposes and to prevent abuse.

2.3 Account and payment records

If you create an account, we store your email address, a password hash or the identifier from Google, GitHub, or Microsoft, and the dates you signed in. If you buy a conversion pack, we store the PayPal order id, capture id, amount, and how many credits remain. PayPal processes the card payment. We do not store card numbers.

2.4 Cookies and Similar Technologies

The site uses the following types of cookies:

  • Essential cookies: Session cookies required for the application to function (e.g., maintaining your session during file upload and conversion). These cookies are necessary and cannot be disabled.
  • Preference cookies: Store your settings and preferences (e.g., selected theme, custom colors) to improve your experience.
  • Analytics cookies: Google Analytics (measurement ID G-JHN7RK651G) stays off until you choose Accept on the cookie banner. Accept turns on analytics storage only. Advertising storage stays denied. The choice is kept in this browser under the name cookie_consent. Decline leaves analytics denied. Clearing this site's stored data brings the banner back so you can choose again.
  • Vercel Web Analytics: A cookieless page-view count. It loads with the page and does not wait for the cookie banner. It receives the page address and basic browser data, not the document you upload or paste.
  • Vercel Speed Insights: A cookieless performance measurement (loading time and layout stability). It loads with the page and does not receive the document you upload or paste.

3. How We Use Your Information

We use the collected information solely for the following purposes:

  • To run MD Converter, MD Publisher, MD Reverse, MD Slides, MD Clip, MD Diagram, MD Diff, and Adoneinu SEO Analyzer
  • To turn Markdown into HTML, DOCX, or PDF, and to build a publisher image from Markdown
  • To extract Markdown from an uploaded DOCX or PDF, or from pasted HTML or text
  • To build a slide deck from an outline
  • To fetch a public webpage for MD Clip, and to convert pasted HTML or email text. Private addresses are refused
  • To draft a diagram from a description or Mermaid source
  • To compare two drafts
  • To monitor and prevent abuse, fraud, or security incidents
  • To comply with legal obligations

4. File Retention and Deletion

Uploaded files and generated conversions are temporary. The bullets below are the cleanup job for files the converter writes to disk. Section 4.1 describes the other tools, which do not all write the same kind of file. This is not a promise that every file disappears within a fixed number of minutes on every host.

  • Generated export: The HTML, DOCX, or PDF file is removed when the download response finishes.
  • Uploaded source: The file you uploaded stays in a temporary folder until a cleanup run deletes it. It is not deleted at the instant export finishes, and it is not kept as a document you can reopen.
  • Long-running server: A cleanup thread wakes every hour. The file-age limit is 0 seconds, so a temporary file that is still present when that run executes is deleted.
  • Serverless hosting: The hourly thread is not started. Temporary files are deleted when an application instance starts. A file can therefore remain until the next instance starts.
  • If cleanup fails: The file stays in the temporary folder until a later run succeeds. A failed run does not create a second copy or a library entry.
  • Account and payment records: If you create an account, the email, sign-in identifier, and credit balance are kept separately from document files for as long as the account exists. A conversion-pack purchase also keeps the PayPal order id, capture id, and amount. Those records are not your document. To ask for deletion, use the contact page.

We do not manually review your uploaded content as part of normal conversion. Deletion of temporary files is automatic.

4.1 What each tool sends

The eight tools share an account, but they do not all handle files the same way. None of them keeps a document library.

  • MD Converter: Uploaded Markdown, and Markdown you paste, is written to a temporary folder so the server can build the preview and the HTML, DOCX, or PDF export. The export is removed when the download finishes. The upload waits for cleanup.
  • MD Publisher: The Markdown you submit is used to build SEO fields and a social image. The download is generated for that response and is not stored as a library item.
  • MD Reverse: Pasted HTML or text is converted in the request. A DOCX or PDF upload is saved to a temporary file for the conversion and deleted when that conversion finishes. The Markdown result is sent back in the download.
  • MD Slides: The outline is sent with the request. The preview does not spend a credit. Each PDF or PowerPoint download is built for that response.
  • MD Clip: A public link is fetched by our server, up to 1 MB of HTML, and turned into Markdown. Pasted HTML and email text are sent with the request. Private, local, and metadata addresses are refused, including loopback, link-local, and private network addresses, and names such as localhost. Fetching the page does not spend a credit. The Markdown download does.
  • MD Diagram: The description or Mermaid source is sent to the server to draft or render the diagram. The preview is free. A .mmd download and a PNG download are separate files, each built for that response.
  • MD Diff: Both drafts are sent to the server. The comparison is not done in the browser. The preview does not spend a credit. The patch download spends one credit only when the drafts differ. The drafts are not stored as documents.
  • Adoneinu SEO Analyzer: The public page is fetched for the audit and is not stored as a document. The preview does not spend a credit. Downloading the plan spends one credit. Private and local addresses are refused.

5. Data Security

We implement appropriate technical and organizational measures to protect your data:

  • Files are transmitted over secure HTTPS connections
  • Uploaded files are stored in isolated temporary directories
  • Access to server infrastructure is restricted to authorized personnel
  • Regular security updates and monitoring are performed

While we strive to protect your data, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security but commit to industry-standard practices.

6. Third-Party Services

Document content is separate from account, payment, analytics, and technical data. The file, pasted text, public page, or drafts you submit are used to build the download. They are not sent to PayPal, to Google, GitHub, or Microsoft sign-in, to the mail server, to Google Fonts, to Font Awesome, to Google Analytics, to Vercel Web Analytics, or to Vercel Speed Insights. Diagram source is drawn in your browser, or by a renderer installed on the server. It is not sent to an external diagram service. Those services receive only the account, payment, message, font, icon, or analytics data named below.

The tools use these third-party services:

  • PayPal: Processes the one-time conversion-pack payment and donations. PayPal receives the amount and your PayPal account details.
  • Google, GitHub, and Microsoft: Used only if you choose those sign-in buttons. They share the profile fields needed to create your account.
  • Email delivery: Verification, password reset, and receipt messages go through the mail server configured for this site.
  • Google Fonts: For typography customization in exported documents. Font requests may be made directly to Google's servers.
  • Font Awesome: For interface icons, loaded via CDN.
  • Vercel Web Analytics: Counts page views for this deployment. The script is loaded from this site at /_vercel/insights/script.js. It does not use a cookie and does not receive document content.
  • Vercel Speed Insights: Records page performance for this deployment. The script is loaded from this site at /_vercel/speed-insights/script.js. It does not use a cookie and does not receive document content.

Uploaded document content is not sold and is not kept as a library. Temporary files are removed by cleanup.

7. Your Rights

Depending on your location, you may have the following rights regarding your personal data:

  • Right to access: Request information about data we hold about you.
  • Right to deletion: Request deletion of your personal data (note: uploaded files are removed from temporary storage by an automatic cleanup job, as described in section 4).
  • Right to object: Object to processing of your personal data.
  • Right to data portability: Request a copy of your data in a portable format.

To exercise these rights, please contact us.

8. Children's Privacy

The Adoneinu tools are not intended for use by individuals under the age of 16. We do not knowingly collect personal information from children. If you believe we have collected information from a child, please contact us immediately.

9. Changes to This Policy

We may update this privacy policy from time to time. Significant changes will be posted on this page. Continued use of the tools after changes constitutes acceptance of the updated policy.
