Cookie Policy
Last updated 9 September 2026 · Version 2026-09-09.2
This policy describes cookies and similar technologies (Retail Replay also uses browser local storage, IndexedDB, and a service worker). See also our Privacy Policy.
1. Essential storage
We use essential storage to operate the Service. These are not advertising cookies.
- Authentication. Session tokens from our sign-in provider so you stay logged in.
- Preferences. Theme, chart layouts, replay speed, and similar settings in local storage.
- Research data. Simulated trades, sessions, and imported CSVs may be stored locally so replay works offline and quickly.
- Service workers. Used to cache chart data and improve load time. They do not serve ads.
2. Performance
We may record first-party error reports and page-performance timings (for example Core Web Vitals) to find bugs. This is not sold to advertisers.
3. Third parties
Google sign-in and our hosting/auth vendors may set their own cookies when you use those features. Their policies apply to those cookies.
4. Your choices
You can block cookies or clear site data in your browser. Doing so will sign you out and may delete locally stored replay sessions. Because essential storage is required for login and replay, we do not offer a “reject all” control that still keeps a working account.
