Day Flipping
Privacy & ads
The short version: no accounts and no user database. Your data stays in your browser. Cloudflare counts page views without cookies. The header can carry up to two Google ads, which supporters don’t see.
What is stored about you
Nothing, on our side. There is no user database, because there are no users — there is no sign-up, no login and no profile.
The things that look like an account are kept by your own browser, in its local storage, on your own machine:
- Your watchlists and saved views
- Your table column layout and saved filters
- Your trade journal and any manual price checks you record
- Small preferences: which game you last used, cursor theme, page size, and the last release notice you were shown
None of it is sent to us. Clearing your browser's site data for this domain deletes all of it permanently, and we cannot recover it, because we never had it.
What the server sees
The site is served by Cloudflare Pages. Serving a page necessarily involves your IP address and your browser's user agent reaching Cloudflare, and Cloudflare's own logging applies. We use Cloudflare Web Analytics to count page views; it sets no cookies and does not build a profile of you. We do not read any of this to build a picture of individuals.
Market data is fetched through a relay on this domain, which forwards requests to Jagex's Grand Exchange data and the Old School RuneScape wiki's price API. The relay passes on no information about who asked. It caches the upstream response and hands the same bytes to everyone.
Advertising
The header has room for up to two advertisements, served by Google AdSense.
Serving them means Google receives your IP address and may read or write cookies in your browser. That is how ad serving works and we cannot make it not be true; what we can do is limit it, so:
- The Topics API is switched off. The site sends a
Permissions-Policythat denies it, so the ad stack cannot use your browser's Topics profile to pick an ad. Google may still personalise ads in other ways where the law allows it. - The ads do not follow you around the page. They are two fixed slots that load once. There are no interstitials, no pop-ups, no auto-playing video and no ads inserted into the data tables.
- Blocking them is fine. The site detects an ad blocker only so that it stops trying to draw an empty box. There is no wall, no countdown and no repeated request to turn it off.
If you are in the EEA, the UK or Switzerland, a separate Google consent dialog will ask about ad personalisation before any personalised ad is served. Google's own description of how it uses data in advertising is at policies.google.com/technologies/partner-sites.
Children
This site is a market tool for a video game and is not directed at children under 13. We do not knowingly collect information from anyone — that is not a policy so much as a description of the architecture.
Changes
If any of the above stops being true, this page changes before the behaviour does. It was last revised on 21 September 2026.
