DWG Viewer opens DWG and DXF drawings in your browser. This page says what happens to your data, starting with the drawing — and then the one part of this site that is not ours, the advertising.
Your drawing
Your drawing never leaves your device. There is no upload step and no server that could receive it. The file is read, drawn and exported by the page's own code, inside your browser. Closing the tab ends it.
The viewer makes no request that carries any part of the file. Nothing here records which drawings you open, and nothing here can: that information never reaches this site.
What is kept on your device
-
Fonts. The first time you open a drawing that
contains text, the viewer downloads the fonts that drawing needs and
keeps them in your browser's IndexedDB (database
mlightcad, storefonts), so a later drawing does not download them again. They stay on your machine; clearing your browser data removes them. -
Nothing else of ours. This site sets no cookie of
its own, writes nothing to
localStorageorsessionStorage, and runs no analytics, no tracking pixel and no fingerprinting. The viewer's own settings are applied for the session only, which is why an earlier visit cannot change what you see.
Advertising
This site is paid for by advertising served by Google AdSense. That script is the only thing on the page that is not ours, so it is worth being exact about.
-
Every page of this site loads Google's ad script,
pagead2.googlesyndication.com, this page included. - Google and its partners set their own cookies and receive the IP address and user-agent of the device asking for the page, and the address of the page itself. They may use that to choose which ads you see, including ads based on your visits to other sites.
- Your drawing is not part of that. It is not passed to the ad script and it is not sent anywhere — it is opened, drawn and exported inside your browser.
- You can switch off personalised advertising in Google Ads Settings, or opt out of many third-party vendors' cookies at aboutads.info. Google's own explanation of what it collects from sites that use its ads is at policies.google.com/technologies/partner-sites.
Every request a page makes to another company
There are exactly two. Nothing else is loaded from anywhere.
-
cdn.jsdelivr.net— the font files, and only when a drawing you open contains text that needs them. - Google's advertising hosts — the ad script above, and the ad it fetches.
Cloudflare
The site is served as static files from Cloudflare Pages, and Cloudflare runs the bot and security checks in front of it. Cloudflare may log brief connection metadata — IP address, request time — to serve the site and protect it. That is network infrastructure logging, not our analytics, and it is outside our control.
What we hold
Nothing from the viewer. The only way to reach us is email at [email protected]; a message you send stays in the mailbox it arrives in. There is no account, no newsletter and no mailing list to be removed from.
If this changes
If something new starts running on these pages, this policy is updated to name it and to say what it collects before it goes live.
