Privacy Policy

Last updated: March 3, 2026

Solitarium.io is a client-side card game site. We do not require accounts. This policy explains what data is stored on your device and what we may collect as the product evolves.

What we store on your device

Games save progress locally in your browser (localStorage) so you can refresh or return later and continue playing. This includes your current game state and the starting seed used for sharing game setups.

What we don’t collect (today)

We do not ask for your name, email, or password. We do not sell personal information.

Analytics and ads

We use Google Analytics 4 (GA4) to understand basic site usage (for example: page views, which games are played, and feature usage like hints/share).

GA4 may set cookies or use similar identifiers, depending on your browser and Google’s settings. We configure GA4 for SPA navigation and enable IP anonymization in our gtag config.

We do not send your email address or any sensitive personal information to GA4 intentionally.

You can limit tracking using browser controls (for example: blocking third‑party scripts/cookies). Google also provides an opt‑out add‑on for some browsers.

We may add advertising in the future. If/when we do, we will update this page with details and any required choices.
