One question, answered well.
Where do my visitors come from, and which of them convert? Every report exists to answer that — nothing else fights for your attention.
Acquisition
Where visitors come from.
Referrers
Search, social, newsletters, other sites — grouped by source.
UTM campaigns
Source, medium and campaign from your tagged links.
Countries
Where your audience is, without storing IP addresses.
Devices
Browser, OS and screen size per visit.
Conversion
Which of them do what you want.
Goals by source
Every goal broken down by the source that brought the visitor.
Funnels
Multi-step flows with the drop-off between each step.
Retention
Cohorts of visitors that come back week after week.
Custom events
Track signups, purchases, anything — and filter by the properties you send.
Read API
Your numbers, from anywhere.
A read-only REST API, authenticated with your site secret. Pull your reports into internal dashboards, scripts or your own monitoring.
- Overview, top pages, referrers and countries
- JavaScript error groups captured by the SDK
- A week-over-week snapshot of traffic, conversions and Web Vitals
curl "https://www.useanalisa.com/api/v1/public/referrers\ ?siteKey=pk_…&from=…&to=…" \ -H "Authorization: Bearer sk_…"
Privacy by default
Measure traffic, not people.
No cookies and no fingerprinting. One random anonymous ID in localStorage counts returning visitors once; IPs are anonymized before anything is stored. GDPR export and deletion are API endpoints, not a support ticket.
- No cookies, no fingerprinting
- IP addresses anonymized at ingest
- GDPR export and deletion by anon_id or user_id
- Events past your quota are dropped, never billed

How is this different from Google Analytics?
It answers one question well — where do my visitors come from, and which of them convert? — instead of offering hundreds of reports. No cookies, IPs anonymized at ingest, fast dashboards from server-side rollups, and GDPR export/delete by API.
Do I need a cookie banner?
We set no cookies. The SDK keeps one random anonymous ID in localStorage so returning visitors are counted once, and IPs are anonymized before anything is stored. Some jurisdictions treat any client-side storage as needing consent, so check with your DPO.
Can I get my data out?
Yes. Every plan has JSON export per anon_id or user_id (the GDPR portability endpoint), and a read API with overview, top pages, referrers, countries, errors and a week-over-week snapshot, authenticated with your site secret.
Will it slow my site down?
The SDK is about 4KB gzipped, loads without blocking render and batches events (every 3 seconds or 10 events, flushed with keepalive when the page closes). Web Vitals are read from the browser’s own performance observers.
What happens if I exceed my plan quota?
Events past 100% of your plan are dropped, never billed as a surprise overage. Upgrade from the billing page whenever you need more.
Can I self-host?
The codebase is three pieces (dashboard, ingestor, SDK). A self-host guide is on the roadmap; contact us if you need it sooner.
