Privacy

You are using this converter inside a separate website, which has its own privacy policy, including its advertising. This page describes only the converter shown in its frame.

Your documents are converted inside your browser. The file itself, its contents and its name are not uploaded, to us or to anyone else.

This is the BurnerDocs document converter, served from engine.burnerdocs.com and shown inside the BurnerDocs website (burnerdocs.com). It is published by Franklin Softworks LLC. This page covers the converter on this address; BurnerDocs' own privacy policy covers its pages, and describes the converter too.

How the conversion works

No server-side processing. The engine, LibreOffice compiled to WebAssembly, runs in a Web Worker inside your browser.
No file uploads. A document you give the converter is read in your browser and is not sent anywhere.
Enforced by the browser. This page carries a Content-Security-Policy of connect-src 'self', which restricts the connections the page's code can make to this address.
No cookies of its own, no analytics, no advertising and no third-party scripts on this address. Cloudflare Web Analytics runs on burnerdocs.com pages only.

What our host can see

The converter is files, and your browser downloads them from Cloudflare, which hosts this address. Those are ordinary web requests, and Cloudflare processes each one: your IP address and approximate location, the date and time, the address requested (including anything after a “?”, such as ?brand=burnerdocs, which names the site that shows the converter), the headers your browser sends (such as its user-agent, language, and any cookies it sends), the connection's protocol and encryption, and the response. We can see statistics and details of individual requests in Cloudflare's dashboard for at least 31 days; Cloudflare also retains request data for its own purposes under the retention criteria in its privacy policy.

Which engine module you download shows the broad kind of file you are working with: a document, a spreadsheet, a presentation or a PDF. Not its contents.
Which fonts your browser requests reflects the fonts and writing systems your document uses.
Cookies. This address sets none. It is part of burnerdocs.com, so your browser sends it any cookies BurnerDocs' pages set (including Google's advertising and consent cookies, since BurnerDocs shows advertising). The converter's code does not read or keep them, but they can appear in the request data above.

What those requests cannot reveal: the contents of your document, its file name, its size, or the converted result. None of that is transmitted.

What is stored in your browser

All of this stays on your device and is not sent anywhere.

Your theme preference (light or dark).
Your format locale, paper size and conversion time choices, if you change them. A date and time you set is forgotten when you close the tab.
Conversion statistics: for each conversion, when it happened, the input and output formats, how long it took, the input file's size, whether it succeeded and which features were on, plus a random value that groups one tab's conversions. Never the file's name or contents. The newest 1,000 are kept, and anything older than 30 days is deleted.
Feature records: which version of a gradually released feature your browser got, kept the same way.
A random identifier used only to decide, on your device, whether your browser gets a feature that is being rolled out gradually. It is not sent anywhere.
A cache of the conversion engine in IndexedDB (wasm-module-cache): about 80–90 MB for each kind of document you convert, and up to about 420 MB for all five. It holds only the engine's program code, never your documents, and stays until a new engine version replaces it, you clear site data, or your browser frees space.

This address uses the same storage whether you use the converter on burnerdocs.com or visit it directly. Clearing site data removes all of it.
