Privacy.
Your inventory, favorites, and saved trades stay on the device and browser you use.
Visitor storage
IndexedDB stores your collection, saved trades, and validated value releases for offline fallback. A theme preference is stored in local storage. Clearing site data removes these records. Browser storage restrictions can prevent persistence; the site reports failures and remains usable for the current session.
Share links and exports
A shared trade is encoded in the URL fragment after the # symbol. It contains that trade’s selected items, quantities, mode, and value release, not your full inventory or other saved trades. URL fragments are not sent in ordinary HTTP requests. Anyone you give the full link to can read the trade.
Exports download a JSON backup to your device. Import files are parsed and validated in your browser. They are not uploaded to the server.
Requests and logs
Normal visitor page, data, and image requests use this site’s origin. The first release includes no advertising, analytics, tracking pixels, or third-party fonts. Hosting and reverse-proxy logs may record request information, including IP addresses, for operation and troubleshooting. Log access and retention are controlled by the self-hosting operator.
Admin sessions
The editorial dashboard uses authentication cookies for administrators. Admin audit records retain actors and changes. Visitor calculator features require no account. Clicking an external quote-source link opens another website whose privacy practices apply there.
Control your data
Export a backup before clearing site data. You can remove inventory entries, favorites, and saved trades individually, or delete all site storage using your browser’s settings.
