Cookie & storage policy
effective August 4, 2026What we use, and what we don't
Solitaire24 sets no cookies of its own, and loads no ad networks, no social pixels and no fingerprinting. Your game data, identity and settings all stay in your browser's local storage, listed in full below.
We do use Google Analytics 4 to measure how the game is used - which pages get visited and which features get played. It sets its own cookies (_ga, _ga_*, typically up to 2 years) and processes usage data as a third party, with IP anonymisation enabled. It never sees your email, your password or the contents of your games.
To opt out: use your browser's cookie controls or blocking extensions for solitaire24.com, or install Google's Analytics opt-out add-on. Blocking it changes nothing about how the game plays.
The complete list - browser local storage
We use your browser's local storage (a cookie-less mechanism that is never sent automatically with requests). This is the complete list:
| Key | What it holds | Purpose | Lifetime |
|---|---|---|---|
| s24_auth_v1 | Your player ID, display name and a signed session token | Keeps you logged in and your stats attached to you - the service itself | Until you log out, delete your account or clear browser data |
| s24_mode | "1" or "3" | Remembers your preferred draw mode for solo play (Turn 1 / Turn 3) | Until cleared |
| s24_mode_daily | "1" or "3" | Remembers which Daily Deal mode you view | Until cleared |
| s24_mode_duel | "1" or "3" | Remembers your preferred duel mode | Until cleared |
| s24_mode_ranks | "1" or "3" | Remembers which leaderboard mode you view | Until cleared |
| s24_winnable | "0" or "1" | Remembers whether you want solver-verified or fully random deals | Until cleared |
How to clear it
Log out on the account page to drop the identity entry, or clear site data for solitaire24.com in your browser settings to remove them all. Without an account, clearing data means your local stats start over; that's the trade-off of storing nothing else about you.
