Privacy
What this site knows about you.
Very little, and none of it by name. There are no accounts, no profiles, no advertising and nothing to buy. This page lists everything a visit stores or sends, in plain terms.
Analytics
The site uses Google Analytics 4 to count visits: which pages are read, roughly where from, on what kind of device, and how visitors arrive. The measurement id is visible in the page source. Google sets its own cookies for this (_ga and _ga_…, kept for up to two years) and processes the data under Google’s privacy policy. Analytics run only on the published site, never in development, and any content blocker that stops Google Analytics stops it here.
Cookies this site sets itself
| Cookie | What it holds | For how long |
|---|---|---|
lo-country | The country chosen on the front page, so the page opens on it next time. | One year |
lo-state | The state or province chosen on the front page, where the country has them. | One year |
lo-lang | The language chosen in the header, so every page comes back in it. | One year |
All are first-party, sent only to this site, and hold nothing but the choice itself.
Kept in your browser only
| Storage key | What it holds |
|---|---|
lo-theme | Light or dark, if you chose one. |
lo-lines | The numbers you saved under My numbers, per game. They stay here unless you turn on draw notifications — see below. |
These live in your browser’s local storage and are not sent to this site or anyone else; the reports about your numbers are computed from data the page already holds. The single exception is draw notifications, which you have to switch on yourself and which are described below. Clearing the site’s data in your browser removes them.
Draw notifications — the one thing you can send us
On a game’s My numbers page there is a button that asks your browser to notify you when a line you play matches enough numbers to win something. It is off until you press it, and pressing it is the only way anything about your numbers leaves your browser.
If you turn it on, this is what we store, and all of it:
- the push endpoint your browser mints — an opaque URL at Google, Mozilla or Apple, which is the only identity involved;
- the two keys that let us encrypt a message so that only your browser can read it;
- the game you asked about, and the lines you asked about.
There is no account, no address and no name — we could not tell you who a subscription belongs to if we wanted to. The lines are compared with each new draw by the same job that records it, and the notification is encrypted end to end: the push service that delivers it cannot read it either. Pressing the same button again deletes the subscription and the lines with it, and so does turning notifications off in your browser — a push service tells us the subscription is gone and we drop the row.
Server logs
Like any web server, ours records each request — address, page, time, browser — in ordinary access logs used to keep the site running and kept only briefly. They are not joined to analytics and not used to identify anyone.
Third parties
Google Analytics is the only third-party service a page talks to. Fonts are bundled with the site rather than fetched from a font service; there are no embedded videos, social widgets or advertising networks. Links to lottery operators and to the sources on the About page lead to sites with policies of their own.
