Privacy Policy

Last updated: August 2026

The short version

QuietCalcs has no user accounts, no databases, and no forms that submit anywhere. Every game runs entirely in your browser. The scores and streaks you build are stored on your own device and are never transmitted to us — we could not read them if we wanted to.

Data stored in your browser

Games save your best scores, streaks and preferences (like your theme and sound settings) in your browser's localStorage, so they survive a page refresh. This data stays on your device, is never transmitted, and is deleted when you use the "reset" option on the Number Score page or clear your browser data.

Hosting and technical logs

The site is served through a content delivery network (Cloudflare). Like virtually all web infrastructure, it processes standard technical data (IP address, browser type, pages requested) to deliver pages and protect against abuse. This isn't combined with any identity — there are no identities here to combine it with.

Analytics

If enabled, we use privacy-focused, cookie-free analytics (Cloudflare Web Analytics) to count page views in aggregate. It does not track you across sites and does not use cookies or persistent identifiers.

Advertising

To fund the site, we may display advertising served by Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your visits to this and other websites. Where required (including the EEA, UK, and Switzerland), you will be shown a consent dialog before any advertising cookies are set, and you can decline. You can also opt out of personalized advertising at Google Ads Settings.

Children

QuietCalcs is a general-audience site suitable for all ages. We do not knowingly collect any personal information from anyone, including children. Because there are no accounts and nothing you play is uploaded, there is no personal data to collect.

Your rights

Because we hold no personal data about you, there is nothing for us to export or delete on request — the data simply isn't here. For data processed by third parties, their privacy policies and controls apply: Cloudflare, Google.

Changes and contact

If this policy changes, the date at the top changes with it. Questions: [email protected].

Frequently asked questions

Do you store my scores on a server?

No. Every game runs entirely in your browser, and your scores are stored only in your own browser's localStorage on your device. Nothing is transmitted to or stored on our servers.

How do I delete my saved data?

Use the "Reset all my scores" button on the Number Score page, or clear your browser's localStorage/cookies for this site.

What data does Google AdSense collect?

Google may use cookies and similar technologies to serve personalized ads based on your browsing activity. You can opt out of personalized advertising at Google Ads Settings, and in the EEA/UK/Switzerland you'll see a consent dialog before any ads cookies are set.

Do you use Google Analytics?

If enabled, we use Cloudflare Web Analytics, which is privacy-focused and cookie-free. It counts page views in aggregate without tracking you across sites or using persistent identifiers.
