Privacy Policy
CalmStacks (“we”) runs free browser games at calmstacks.com. This policy explains what we collect and how ads/tips keep the site online.
What we collect
- Gameplay progress (personal bests, rounds played) stored only in your browser via
localStorage— never uploaded to our servers. Clearing site data resets progress. - Consent choice (accept/decline ads) stored locally.
- Anonymous analytics via Cloudflare Web Analytics when enabled (no advertising cookies from us).
- Advertising data if you accept ads — Google AdSense and partners may use cookies/device signals under their policies (varies by region).
International visitors
CalmStacks is available worldwide. The site is written in English. Ad personalization and consent follow your choice and local requirements where Google’s consent tooling applies. Scores stay on your device regardless of country.
Ads & tips
The site is free. Revenue comes from optional tips and display ads after you accept. Declining ads disables AdSense scripts; you can still play and tip.
Your choices
- Use the consent banner to accept or decline ads.
- Clear site data in your browser to reset consent and local scores.
