Privacy
Last updated: November 9, 2026
Short version: FoS has no accounts, no ads, no cookies and no tracking. Your game data stays in your own browser.
What stays on your device
Your progress, scores, streak, settings and notebook are saved in your browser’s local storage. They never leave your device, and we can’t see them. Clearing your browser data erases them, and so does “Reset all stats” in Settings.
What our hosting sees
The site is hosted on Cloudflare. Like any web host, Cloudflare processes basic technical information (such as your IP address and browser type) to deliver the pages and protect the site from abuse. See Cloudflare’s privacy policy.
Analytics
We may use Cloudflare Web Analytics to count visits. It doesn’t use cookies, doesn’t fingerprint you and doesn’t track you across sites. We only see totals, such as how many people visited today.
Fonts and other services
All fonts and files are served from this site. No requests go to Google or any ad network.
If you email feedback@fos-daily.win, we use your address only to reply to you.
Children
FoS doesn’t collect personal information from anyone, including children.
Changes
If this policy changes (for example, if we add an optional email list or a global leaderboard), we’ll update this page and the date above before the change goes live.
