Privacy and your data

Effective date: 2026-09-15 — the date this site first became publicly available.

What stays on your device

Your platform, patch, owned items, progress, builds, and notes (your PlayerState) are stored locally in this browser by default. No account is required, and nothing is synced anywhere.

What leaves your device, only if you choose

If you create a share link, only the fields you select are copied into the shared record, along with an opaque link token and timestamps. Never game or platform credentials, official account IDs, legal names, precise location, or contact lists. At this stage, shared records are stored on the sharing device itself; server-side sharing is not yet active.

Cookies and local storage

This site and its analytics provider set no cookies in your browser. Your saved PlayerState and privacy choices use browser storage on this device only. Plausible reads its local opt-out flag when you decline analytics. No advertising, cross-site tracking, or social-media embeds are present.

Analytics

We use Plausible, self-hosted by ShipSolo at plausible.shipsolo.io, for aggregate pageview analytics. A default pageview contains the page URL and referring page URL; ordinary request metadata such as IP address, browser user agent, and request time may also be processed to deliver and protect the service. We send no custom events.

Analytics fail closed whenever a URL has a query string or fragment, so search text and share capabilities are not sent. PlayerState, owned-item lists, builds, progress, notes, imported or exported data, profile or state identifiers, and share view or revoke tokens are never analytics fields. No analytics request is made after you choose Decline in Settings.

Your controls

You can export your state as a file, import it later, revoke shared links, and delete your local and shared data. Deletion covers your local state, saved builds, import rollback copies, and share records created on this device.

Hosting and third parties

This site is hosted on Cloudflare (Workers and Static Assets). ShipSolo operates our self-hosted Plausible analytics service at plausible.shipsolo.io. There are no advertising networks or social-media embeds. Cloudflare and ShipSolo may process ordinary request metadata under their own service practices; analytics retention is not published to us and is currently unknown.

Retention and changes

Your PlayerState and any share records you create are stored on your device and are retained until you delete them. We do not operate a server-side copy. When this policy changes, the revised version is published on this page with an updated effective date; the effective date shown at the top of this page is the date the site first became publicly available. Questions about this policy can be sent to support@halloweenthegametracker.online.
