Privacy policy

Last updated 12 November 2026

Halve is built to collect as little as possible. There are no accounts, and your scores stay on your device. This page explains what does get stored or shared, including by our advertising partners.

What Halve stores on your device

Halve uses your browser’s local storage to remember your progress: today’s results, your streak, your statistics and, if you set one, the display name you use in online games. This information never leaves your device unless you choose to copy and share a result. You can delete it at any time by clearing this site’s data in your browser settings.

Advertising

Halve is free and is supported by advertising. We use Google AdSense to show ads.

• Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites.
• Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the internet.
• You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info.
• For more on how Google uses data, see How Google uses information from sites or apps that use its services.

If you are in the European Economic Area, the United Kingdom or Switzerland, you will be asked for your consent before personalised ads or advertising cookies are used, and you can change your choice at any time using the privacy settings link shown with the consent message. Where required by US state privacy laws, you can also opt out of the sale or sharing of your personal information through the same messaging.

Online play

When you play online, your browser connects directly to your opponent’s browser using WebRTC. To set up that connection, a public signalling service (PeerJS) briefly handles connection details, and your opponent’s browser can see your IP address, as with any direct connection. The game sends your moves, scores and display name to your opponent. Nothing about the match is stored by us.

Other services

• Hosting. The site is hosted by Cloudflare, which processes standard request information (such as IP address, browser type and the page requested) to deliver and protect the site, and keeps aggregated logs to help us find errors and measure traffic.
• Fonts. Text fonts are loaded from Google Fonts, which receives your IP address and browser information when the fonts download.
• Scripts. The online-play library is loaded from jsDelivr only when you start an online game.

Children

Halve is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children.

Your choices

• Clear this site’s data in your browser to remove your saved progress and name.
• Manage ad personalisation through the consent message or Google Ads Settings.
• Use your browser’s settings to block or delete cookies.
