What Y2DAY knows about you
As little as a website can reasonably know. There is nothing to sign in to, nothing to subscribe to, and no advertising anywhere on the site. This page describes what is actually true today.
No accounts
Y2DAY has no user accounts, no sign-in, and no profiles. It never asks for a name, an email address, or a payment method, and there is no personalisation built on who you are. Everyone reading today’s edition sees the same edition.
What is stored in your browser
One thing: whether you prefer the day or the night edition. It is kept in your own browser’s local storage under the key y2day-theme, it holds nothing but that preference, it is not an identifier, and clearing your site data removes it. Nothing else about your visit is written to your device by Y2DAY.
No advertising, no ad tracking
Y2DAY carries no advertising and no advertising network, so there is no ad profile, no behavioural targeting, and no ad-tech identifier attached to your reading.
The data Y2DAY reads is not about you
The attention signals behind the site come from Wikimedia’s public pageview data. That data is aggregated before Y2DAY ever sees it: page-level attention published in hourly aggregates, and — as a separate signal — daily country-level figures that Wikimedia already privacy-protects at source by withholding small counts. Y2DAY cannot see, and cannot reconstruct, who read which article. This is also why a country can be absent from the map without meaning zero.
Reading a topic on Y2DAY does not send anything to Wikipedia on your behalf. Following a link out to Wikipedia, Wikimedia Commons or a source publisher takes you to that organisation, under their own privacy practices.
Server logs, hosting and measurement
The site contains no analytics script and no third-party tracker. Y2DAY is served by Cloudflare Workers; background jobs run on Cloudflare Workers, Workflows, and Containers, with the Container constrained to EU/Western Europe. Editorial content and operational state live in a managed PostgreSQL database in Frankfurt, and your browser never connects to that database directly.
For reliability and incident response, production keeps Cloudflare Workers invocation logs and traces, which can include request, response, execution, and related network metadata. Y2DAY is therefore not an anonymous or no-logging service. The intended retention for these operational logs is at most seven days.
