Privacy.
We collect almost nothing. Here's the entire list.
Stored on your device
Personal-best scores, current-game saves, sound preference, and theme choice are stored in your browser's localStorage. Nothing is sent to a server. Clear your site data and it's gone.
Sent to us
- Contact form submissions — when you write us, your name, email, and message are emailed to our inbox via Resend. Used only to reply to you. Not stored anywhere else.
- Bug reports — the in-game "Report bug" button sends the game slug, current seed, score, moves, time, your optional message, and browser user-agent. Used only to reproduce the issue.
- (Coming later) Global high scores — when you opt to publish a score, we store the game slug, your 3 initials, score, moves, time, seed, and salted hashes of your IP and user-agent (for abuse rate-limiting). No personal data is stored.
Analytics
We use Vercel Analytics for aggregate page-view counts (how many people opened Klondike this week, that sort of thing). It doesn't use cookies and doesn't identify individual visitors. We don't use Google Analytics, Meta Pixel, or any ad-network tracking pixels.
Ads
Ad slots are reserved on game pages but not yet served. When ads go live (AdSense or similar), the ad network may set its own cookies — that's outside our control. We'll keep ads above the felt, never on top of it, and we'll never run auto-play video.
Cookies
No cookies set by us. Theme and sound preferences use localStorage, not cookies. Future ads (when live) may set their own — see above.
Questions
Write us and we'll answer in plain English.
