This week's reading didn't load.
The dataset that backs this dashboard couldn't be reached, so we're showing nothing rather than stale or partial numbers. The grade an instrument can't measure is no grade at all.

This week's reading
Read the web on two axes.
Every site, every measure
Click a column to sort · click a row to inspect.| Site | Vertical | Grade | Consent | Restraint | Do-Not-Sell |
|---|
Consent = consent-effort score (0–100, higher is more effort) · Restraint = tracking-restraint score (0–100, higher means fewer tracking companies reached by default) · Do-Not-Sell = opt-out link detected · hover any column header for detail.
What this instrument can't see
The honest edges of the measurement — methodology published in full.One vantage point
We crawl as a first-time U.S. visitor. Sites that behave differently for European visitors — or gate tracking only for certain states — show us their U.S. default, nothing else.
Restraint can be invisible
A site that blocks its tags entirely until consent shows us nothing — indistinguishable from having no tags at all. We only credit restraint we can observe, and never count its absence against a site.
Ties are real ties
Sites with only a privacy policy score exactly alike, so they plot exactly alike. We don't scatter points artificially to look more precise than the measurement is.
One visit, weekly
Ad markets are dynamic — the exact vendor set varies visit to visit. Breadth of distinct parties is far more stable than request counts, but week-to-week movement is normal. Some heavy media sites remain under-sampled.
The companies behind the grades
The companies that follow you from site to site, plus the full ranked roster of every tracker we classify.Measured across — sites · —
What this directory can and can't tell you
The honest edges of this roster — methodology published in full.Present, not proven
We can see that a company was contacted, and often that it synced an identifier. What happens to your data afterward is out of the browser's view — presence is evidence of exposure, not a finding of harm.
Syncing is a floor, not a ceiling
"Observed syncing" counts only the identifier matches we caught in the network trace. A company can recognize you in ways we can't watch, so the cross-site reach shown here is a lower bound.
One label per company
We name the company behind a tracker from a public registry. Some vendors run under many domains, and ones we haven't identified yet show as "Unknown" until the registry catches up.
A weekly snapshot
Each reading is one visit per site, once a week. The exact tracker set shifts visit to visit — the roster shows what fired this crawl, not a permanent list.
