SourceStamp runs entirely on your device and has no backend. The short version: nothing leaves your browser.
SourceStamp has no server, no account, no analytics, and no tracking. We (the developer) never receive any data from you. The extension makes no network requests.
When you click the SourceStamp icon, it reads the current page once, locally — its bibliographic metadata (citation_* / Highwire meta tags, schema.org JSON-LD, Dublin Core, OpenGraph, the page title and any DOI) — so it can build a citation. This runs in your browser. It happens only on the tab you explicitly click, only at that moment (Chrome's activeTab permission); the extension has no standing access to any website.
Your default citation style and last-used export format are saved only on your device using Chrome's storage API. In the Pro version, your saved bibliography list is likewise stored only locally (it does not sync across devices). This data never leaves your machine and can be cleared by removing the extension. BibTeX/RIS files you export are saved by you, to your own computer, when you choose to.
activeTab — read the tab you click the icon on, at that moment.scripting — inject the one-shot, read-only metadata scan into that tab.storage — keep your style/format preference (and the Pro bibliography) locally.Questions: [email protected]
