GI Signals collects the email address you provide when you subscribe, solely to send you the weekly issue. We use a double opt-in: you confirm via a link before any newsletter is sent. We never sell or share your address. Every email includes a one-click unsubscribe, and you can unsubscribe at any time.
We count page visits and how readers use an issue: which pages are opened, which site referred you, your country, whether you are on a phone or a desktop, how far down a page you read, and which share, cite and source links are used. Our analytics set no cookies, use no advertising or third-party trackers, and build no cross-site profile. The only cookie this site can set is the sign-in cookie for the optional saved-library feature, and only if you ask for a sign-in link. None of it is sold, shared, or tied to your clinical activity.
To count people rather than page loads without identifying anyone, each day we generate a random, rotating secret and discard it within 48 hours. Your IP address and browser identification string are combined with that day's secret into a one-way fingerprint; for analytics we never store the address or the browser string themselves. Two other places touch them briefly and separately: a submitted feedback report keeps your browser string with the report so we can reproduce the problem, and the subscribe form counts requests per address for one hour to block automated sign-up floods. Once the day's secret is gone the fingerprint cannot be traced back to you or matched to any other day, by us or by anyone else. It is deliberately impossible for us to follow one reader across two days.
For the weekly email we use our sending provider's link tracking to count clicks on the links in an issue, so we can tell which papers were useful. Our provider also reports opens, which we record as per-issue totals. We do not treat opens as a measure of engagement: many mail clients fetch the tracking image automatically, so a large share of them are machine-generated rather than real reads, and clicks are what we actually rely on. None of it is sold, shared, or profiled.
