Cookies are small files a site stores on your device. This explains every one this site uses. Under the UK's Privacy and Electronic Communications Regulations and the EU ePrivacy Directive, consent is required before storing anything on your device — except where it is strictly necessary to deliver something you asked for. We tell you about those, and we would ask about anything else.
tradebrooke_session — strictly necessary. Keeps you signed in between pages so you are not asked for your password on every click. It holds a random identifier, never your password, and expires when your session lapses or you sign out. tb_consent — strictly necessary. Records the cookie choice you made, so we can honour it and stop asking. It holds your categories, a version number and a timestamp; nothing that identifies you. It lasts 180 days, after which we ask again rather than assume your answer still stands. tb_rsv — strictly necessary, and only set if you use it. When you flip the RS switch beside the market flags between RSV1 and RSV2, this remembers which one you chose, so the themes are staged the way you asked on every page and next visit. It holds v1 or v2 and nothing else, and lasts a year. Never touch the switch and it is never set.
No advertising cookies. No cross-site tracking. No social media pixels. No fingerprinting, no data brokers, no selling or sharing of personal data. No analytics either — the Analytics category in the settings panel is switched off and stores nothing, so that if measurement is ever added it is opt-in from the first day rather than bolted on afterwards.
Fonts and the interface library are loaded from Google Fonts and unpkg. They set no cookies for us, but the request itself discloses your IP address to those providers, which is why they are named here rather than left unsaid. Market data is fetched by the server, not your browser, so data vendors never see you.
Use the Cookie settings link in the footer of any page. It reopens the same panel you saw on your first visit. Withdrawing is one click, exactly like giving, and takes effect immediately. There is no cookie wall — refusing optional cookies restricts nothing.
Every major browser can block or delete cookies, under Privacy in Settings. Blocking strictly necessary cookies will stop you signing in, because the session cookie is how the site recognises you between pages. Deleting tb_consent simply means you will be asked again next visit.
