Privacy Policy
Last updated: 2026-10 · The English version is canonical.
1. What we collect
Account data you provide (name, email, a salted password hash), the simulated trading activity your account generates (orders, trades, listings, simulated retirements), and any feedback you submit through the feedback form (your message and, if you choose, a contact address). Conditional orders and price alerts you set are stored with your account, as are the in-app notifications the service writes for you about fills, conditional orders and price alerts. First-party product analytics record anonymous page views and funnel events (an opaque visitor id in a cookie; no cross-site tracking).
2. What we do not collect
No payment data (there are no payments), no government IDs, no third-party trackers, no advertising identifiers.
3. How data is used
To operate the simulation, keep you signed in (session cookie), respond to feedback, and understand aggregate product usage. We do not sell or share personal data.
4. Cookies and local storage
cx_session keeps you signed in; cx_vid is an anonymous visitor id for first-party analytics. Display preferences stay in this browser's local storage: carbadia-theme (light or dark), carbadia-lang (language), carbadia-updown (whether green or red marks a rising price), carbadia-tz (the time zone used to show times: this browser's own, Beijing time or UTC) and carbadia-terminal-prefs (the trading terminal's chart interval, order-book grouping and depth, bottom tab, indicators, last symbol and row density, compact or comfortable); carbadia-credit-watchlist keeps your watchlist on this browser. The terminal pages use the dark look until you pick one yourself; that default is derived from the page you are on and is not written to local storage.
5. Retention and deletion
Simulated market history is pruned routinely. In-app notifications are deleted after 30 days. To delete your account and its data, email hello@carbadia.io from the registered address.
