ACM DL PDF Redirector
Last updated: June 23, 2026
Short version: ACM DL PDF Redirector collects nothing, sends nothing, and stores nothing. It has no servers, no analytics, and no tracking. It runs entirely inside your browser, only on dl.acm.org.
ACM DL PDF Redirector is a small Chrome extension for the ACM Digital Library. On dl.acm.org, it rewrites paper links of the form /doi/epdf/… to /doi/pdf/… so that papers open as raw PDFs in your browser's default PDF viewer instead of ACM's in-browser eReader.
That URL rewrite is the extension's only function. All of it happens locally, in your browser, as pages load.
None. The extension does not collect, store, transmit, or sell any information about you. Specifically, it does not collect:
The extension has no backend servers and makes no network requests of its own. It does not contain any analytics, telemetry, advertising, or tracking code. Nothing about your activity ever leaves your computer because of this extension.
The extension requests only the minimum permissions required to do its job:
dl.acm.org — so the extension can read and rewrite epdf links into pdf links on ACM Digital Library pages. It does not run on, or have access to, any other website.declarativeNetRequest — used to register a single static redirect rule that sends any navigation to /doi/epdf/… to the corresponding /doi/pdf/… URL. This rule is declared up front; the extension cannot read the contents of your network requests.Because the extension collects no data, there is nothing to share, sell, or disclose to any third party.
The extension does not collect any information from anyone, including children under 13.
If this extension's behavior ever changes in a way that affects privacy, this page will be updated and the "Last updated" date above revised. Continued use after a change constitutes acceptance of the revised policy.
