Data Stored On Your Device

QUIZ 5秒の選択 stores settings such as audio, vibration, and nickname in your browser's localStorage under `quiz5sec-settings`. Solo personal-best records are stored in localStorage under `quiz5sec-personal-bests`. These values are used to restore your preferences and local scores on the same device.

When you add a custom quiz pack, the normalized pack content and its source URL are stored in localStorage under `quiz5sec-custom-packs-v1` and `quiz5sec-custom-pack-urls-v1`. Adding or receiving another custom pack with the same pack ID updates that saved entry. You can remove saved custom packs from the pack selection screen.

Analytics

The web app includes Google Analytics measurement ID `G-B79JGJV5EZ`. Google Analytics may receive page views and gameplay events such as solo completion, room completion, install prompts, and related event parameters. Google Analytics may also process technical browser or device information, device or other identifiers, and approximate location inferred from network information. Query parameters and URL fragments are removed from the page URL before analytics configuration, so room invite codes and custom-pack URLs are not included in the analytics page URL. The app's event helper skips analytics event calls in Vite development mode.

The production site is delivered through Cloudflare. Cloudflare Web Analytics may process page path, referrer, country, browser, operating system, device type, and Web Vitals for aggregate analytics. Cloudflare security features may also process technical browser signals and a security cookie to detect automated or abusive traffic.

Room Play And Network Data

Solo play can run from static web assets. Room play connects to the configured WebSocket room server. When you create or join a room, the app sends the nickname you entered, the room code, selected pack/settings, answer choice IDs, round indexes, and one-time answer tokens needed to run the match. If a host selects a custom pack, the pack content and its source URL (when available) are sent through the room server to room participants when the game starts, and participants save that pack on their devices. The room server also sends room state, public nicknames, answer status, chosen answers after the public-answer phase, scores, and rankings to room participants.

The room server keeps active room state in memory and does not use accounts or an application database. Empty rooms that remain inactive for one hour are removed by a cleanup task that runs every five minutes. Temporary client IDs, reconnect tokens, and answer nonces are generated for room operation and replay protection. The current server writes basic operational messages, including temporary client IDs and the room code and host nickname when a room is created, to its standard service logs. The hosting provider may also process technical connection logs needed to deliver and secure the service. These logs follow the hosting provider's retention controls; the developer does not currently provide a verified way to identify and delete one user's entries.

Other Networking

The game downloads static app files, quiz packs, images, audio, Google Fonts, and service-worker cache data. Google Analytics requests are sent to Google when analytics is active. Share buttons may open the selected sharing service or copy/share the game URL when you choose to share. A custom-pack source URL is stored and, during room play, shared with room participants as entered; do not use a URL that contains a private access token or other secret. The current app can read compatible quiz packs from external URLs, but it does not provide an in-app editor, submission system, or public publishing service.

What This Game Does Not Use

QUIZ 5秒の選択 does not use advertising, in-app purchases, user accounts, login, device location permission or precise location, camera, or microphone access.

Security And Deletion

The production app transfers its own files and analytics requests over HTTPS/TLS, and room play uses the configured secure WebSocket endpoint. You can remove custom packs in the pack selection screen. To delete all other data stored locally by the game, clear the site's browser data or the Android app's storage. Empty room state is removed as described above. The developer does not currently provide a verified way to identify and delete an individual user's data already processed in Google Analytics or standard hosting logs.
