Fauxx - Privacy Through Noise
APK
Fauxx is an open-source privacy tool that protects you by generating diverse synthetic browsing activity in the background. By flooding data brokers and ad-tech platforms with plausible off-demographic noise, Fauxx makes your real behavioral signal statistically indistinguishable from fake data. This is the FULL version distributed via F-Droid and GitHub. It includes all modules, including location spoofing and ad profile pollution, which are not available in the Play Store version due to Google's policies. HOW IT WORKS Fauxx runs quietly in the background and performs diverse browsing activities across many topic categories — searches, page visits, DNS lookups, fingerprint rotation, ad profile pollution, and GPS location spoofing. The goal is to bury your real interests under a mountain of synthetic noise so that data brokers can't build an accurate profile of you. FEATURES • Diverse search queries across Google, Bing, DuckDuckGo, and Yahoo on topics far from your real interests • Varied website visits across dozens of content categories • Ad profile pollution — loads ad-heavy pages to inject off-demographic ad signals • GPS location spoofing — feeds fake coordinates via mock location provider (requires developer options) • Browser fingerprint rotation (User-Agent, canvas noise, language headers) • DNS query diversification • Smart targeting engine with 3 layers of demographic distancing • Synthetic persona rotation — adopts a new fake identity every week • Poisson-distributed timing that mimics natural human browsing patterns • Full audit log with CSV/JSON export • On-device encryption for all personal data (SQLCipher + Android Keystore) • No accounts, no cloud storage, no analytics, no telemetry OPTIONAL DEMOGRAPHIC TARGETING Tell Fauxx about yourself (age, gender, interests, profession, region) and it will generate noise that's maximally different from your real profile. All demographic data stays encrypted on your device. Skip the setup entirely for uniform random noise. PRIVACY FIRST • All data stays on your device • No analytics, no crash reporting, no advertising identifiers • Fully open-source — inspect the code yourself • Clear All Data option to wipe everything instantly Fauxx is free, open-source, and contains no ads.
