coinfinance uses no advertising, analytics or cross-site tracking cookies. This page lists what it stores on your device. Essential items need no consent; optional ones follow the choice you make under “Privacy choices” in the footer.
Essential (no consent needed)
- Cookie: the session cookie set by our sign-in system when you sign in. It keeps you signed in and is removed when you sign out or it expires.
- Local storage `coinfinance:board` (your boards and widget settings), `coinfinance:board:guest-backup` and `coinfinance:board:invalid` (safety copies made when boards are merged or cannot be read), `coinfinance-index-proxies` (your index data-source choice), `coinfinance.library.type` (the library filter you picked), `coinfinance:onboarding` (sign-up prompts you dismissed), `coinfinance:premium-hint` (a hint that your plan is premium), `coinfinance:reco-country` (the country you picked for widget and board suggestions) and `coinfinance:consent` (your privacy choice and its version). They stay on your device until you clear them. The theme (light or dark) is saved in the `theme` key by the theme switcher.
- Session storage `coinfinance:resume`: remembers what you were doing across the sign-in redirect; removed when the tab closes.
Optional (your choice)
- Ad measurement: the counters for impressions and clicks of our own ad spots, and session storage “coinfinance:ads:seen” in the current tab (which spots were already counted). No identifier is created. It is off until you accept. In the EU/EEA, the UK and Brazil we ask you; everywhere else it stays off unless you turn it on under “Privacy choices”. Refusing never changes what you can do on coinfinance.
Your region
- We decide whether to ask for consent from the approximate country of your IP address, determined on our server. The country you may pick for suggestions never changes that. Your language and browser settings play no part. Optional storage stays off unless you accept it, wherever you are.
