## Deep links (interactive app)

After analysis completes, URL parameters activate tabs or highlight inference cards:

- `tab` — overview, improve, ua, headers, geo, javascript, combined
- `highlight` — inference id (e.g. `canvas_fingerprint`, `ua_ch_high_entropy`)
- `src` — campaign/source slug (preserved with other params)

Examples:

- https://howprivateami.com/?tab=improve&src=anti-fingerprinting
- https://howprivateami.com/?highlight=canvas_fingerprint&src=canvas-fingerprint
- https://howprivateami.com/?tab=headers&highlight=ua_ch_high_entropy&src=client-hints
- https://howprivateami.com/?tab=ua&src=user-agent

## What this tool does

- Parses User-Agent and HTTP headers server-side
- Runs JavaScript signal collection in the browser (screen, language, timezone, etc.)
- Runs advanced fingerprint probes (canvas, WebGL, audio, fonts)
- Derives approximate geolocation locally from IP (MaxMind GeoLite2; IP not shown in report)
- Returns attributed inferences, exposure level (low/moderate/high), and privacy score (0–100, higher is better)
- Optionally compares your score to anonymized scores from recent visits on this instance

## What it does NOT do

- No user accounts or registration
- No advertising profiles or cross-site tracking cookies
- Does not persist full analysis results as a personal user record
- Does not use your data for authentication or security decisions about you

## Data retention

- Analysis output is returned in the HTTP response only
- Privacy benchmark: rolling window of up to 1,000 anonymized scores (score, exposure band, browser family, country code)
- Request logs: operator-configured JSONL logs may include IP, User-Agent, path, and metadata
