Scope

Operating blind makes it hard to prioritize UX work. Add cookieless, opt-in analytics (Plausible or PostHog cookieless mode).

Acceptance criteria

• Pick provider (recommend Plausible)
• Opt-in banner on first visit; remembered in localStorage
• Track: page views, key flow events (connect wallet, send submitted, scan triggered, withdraw)
• No PII (no wallet addresses, no amounts)
• Public privacy page describing what we collect

Files to start with

• Provider integrated
• Opt-in flow functional
• Privacy page committed
• Events firing correctly (manual verification)
• Documentation
