Fauxx

The problem

Data brokers, ad networks and analytics platforms collect the searches you make, the links you click and the places you go. Over time they build a detailed profile of who you are and what you’re likely to do next, and that profile gets sold and merged with others. Once it exists, you can’t realistically get it deleted.

So instead of trying to delete it, Fauxx buries it in noise.

How it works

Fauxx runs in the background and generates continuous, plausible activity that doesn’t match your real demographics: search queries, page visits, DNS lookups, fingerprint rotation, ad-profile pollution and optional GPS spoofing, spread across seven independent modules. Your real activity is still there, mixed with enough synthetic activity that data brokers can’t confidently tell the two apart.

The Demographic Distancing Engine decides where the noise goes, in four layers. The base layer (Layer 0) spreads it evenly across every content category. An optional self-report (Layer 1) steers it away from your real interests. If you opt in, Layer 2 reads the interests your existing ad-platform profiles have already assigned you and fills in the gaps. On top of that, a weekly synthetic persona (Layer 3) rotates so that long-term pattern detection fails.

Timing follows a Poisson distribution, slowed down at night, so the traffic looks like a person rather than a bot. Every URL is checked against a built-in blocklist, and a per-domain rate limit (at least 5 seconds apart, at most 200 an hour) prevents abuse.

Privacy

Your demographic data, settings and activity log stay on the phone, in a SQLCipher database whose key is wrapped by the Android Keystore. There’s no telemetry, analytics, cloud sync or account. The ad-platform scrapers only read. Sensitive attributes (race, religion, sexual orientation, gender identity, disability, political affiliation) are never stored or used to steer the noise.

Status

Beta. The full build is available from GitHub Releases and F-Droid. A reduced Play Store build, without location spoofing and ad-profile pollution (which Play’s policies don’t allow), is distributed separately.
