How much data does your favorite app actually collect?

Every app on the iOS App Store publishes a privacy label — a list of the data types its developer says the app collects. Apple shows it once, on one product page, for one app at a time. Nobody reads a thousand of them back to back to see how apps actually compare.

So we did. As of this writing, privacybench has read 12,779 apps, scored 11,787 of them, from 16,171 weekly snapshots — and that number grows every week.

One formula, not a vibe

Every score comes from the same published formula: count the distinct data types an app declares, weight them by group (tracking counts most — that data follows you across other companies' apps and sites), scale to 0–100. No editorial judgment call per app, no hidden adjustments. The full methodology shows the exact weights and the math behind any single score.

What Apple's own page doesn't show you

A privacy label isn't static. Developers update apps, and sometimes the declared data types change along with them — quietly, with no changelog, no notification, nothing that shows up if you only ever look at the current label. We capture a snapshot every week and keep every one of them, so when a label changes, it shows up as a change instead of disappearing into an overwritten page. See what's moved recently on the changes page.

Declared, not verified — on purpose

A high score means an app declares collecting a lot. It isn't a verdict, and it isn't proof of anything an app was caught doing — Apple doesn't verify these labels, and neither do we. What we do is read every one exactly as published, apply one consistent formula, and keep the history. That's the whole product.

See where your own apps land

The full ranking is filterable by category and storefront, and every app has its own page with a declared-data breakdown and its score history over time. Start with something you use every day — the answer is sometimes exactly what you'd expect, and sometimes not even close.
