Cookie & Local Storage Notice

01What we store

• Strictly necessary: your login session token, security tokens and rate-limit state. Without these the service cannot sign you in.
• Preferences: interface language, theme, dismissed banners, which onboarding tips you have seen.
• First-party analytics: page views and in-product events (for example which step of the wizard you reached or which button you used), tied to a random identifier stored in your browser and, after you sign in, to your account, so we can see where people get stuck and improve the product. IP addresses are truncated before storage, there are no third-party trackers and no cross-site tracking, and raw events are deleted after 12 months (aggregate totals are kept).
• Attribution: the first campaign parameters or referring site that brought you here, kept in your browser until you sign up, used for our own statistics. If you came from one of our ads, the ad's click identifier is kept too and, after you sign up, used to tell that ad platform about your sign-up and purchases (see the Privacy Policy, Section 04).
