Privacy policy

Last updated: 22 September 2026

ByteBuffer is a Chrome extension that opens short casual games in the browser’s side panel. This page describes how the product handles data today.

Accounts and browsing

We do not create accounts. We do not collect your name, email, or other contact details. We do not read the pages you browse. We do not record keystrokes outside the games.

What stays on your device

Game scores, saves, mute preference, language, and similar settings are stored locally in the browser. They are used to resume a game, remember settings, and notice when a game has an update. Clearing site data or using the in-product “Clear” actions removes them.

Analytics

The Chrome extension sends anonymous usage events to Google Analytics: that you opened the side panel, and which game you opened. It uses a random identifier created on this install. That identifier is not an account and does not follow you across devices.

We do not send scores, saves, what you type, or the addresses of other tabs. Uninstalling the extension stops these events. Google processes them under Google’s privacy policy.

Network requests

The extension loads games from sites we operate and may fetch a small versions file so cached games can update. After a game is cached, it can be played without a network. Analytics events above go to Google’s Measurement Protocol endpoint.

The marketing site https://www.bytebuffer.app is a static site. Your browser will request the page and assets like any other website.

Permissions

The extension uses Chrome’s side panel and local storage. Storage also keeps the random Analytics identifier. It requests host access to our play site to load games, and to Google Analytics to send the usage events above.

Children

ByteBuffer is a general-audience set of casual games. We do not knowingly collect personal information from children.

Changes

If this policy changes, we will update the date above.

Questions about this policy: use the support link on the Chrome Web Store listing once it is live, or the contact path published on www.bytebuffer.app.
