Project details
This page expands the short notice you see inside the app. Read on for every detail of the study.
Standard SDKs and JavaScript APIs give developers great features, but the same attributes can combine into a device fingerprint. We measure how unique those fingerprints are and build better privacy defences.
- Gauge how unique a phone looks from API data available to any SDK developer.
- Compare native-SDK vs. JavaScript fingerprints.
After you tap I Consent the app records harmless attributes (model, OS version, screen size, network operator & more) that any normal app can access. A WebView inside the app does the same from the browser side.
Data travel encrypted to our university server, are anonymised where possible, and processed only for the goals above.
Examples of what we log:
- Device model, manufacturer, OS version
- Screen resolution & pixel density
- Network operator name (no phone number)
- WebView properties (user-agent, WebGL vendor…)
No photos, contacts, or local files .
- Data live on an encrypted database at EURECOM.
- Only anonymised aggregates may reach partner universities.
- Your identity is never published.
- Raw data are deleted when the study ends.
GDPR gives you the right to access, correct or erase your data at any time. Email rgpd@eurecom.fr or use the app’s “Contact Us” form and quote your user-ID.
- Risk: none beyond normal app use.
- Compensation: none – purely academic work.
- Voluntary: quit at any time; request deletion at any time.
By tapping I Consent in the app you confirm that …
- you’ve read and understood this information,
- your data are for academic research only,
- you may withdraw with no downside.
