WhatsSpy Public is a web-based proof-of-concept application created to demonstrate potential privacy weaknesses in WhatsApp. The project explored how a user’s activity and profile information could be observed over time, raising concerns about the privacy implications of online status visibility and other account details.
The project is distinct from the similarly named WhatsSpy application. Its original research focused on demonstrating how exposed activity indicators could reveal patterns in a person’s daily smartphone usage. The project is now best treated as a historical privacy research reference rather than a dependable, current WhatsApp monitoring solution.
WhatsSpy Public explored several types of WhatsApp account information and activity indicators. Its original feature set included:
The original project also advertised English, German, Spanish, and Dutch language support. Feature availability depended on the WhatsApp environment and the project’s compatibility at the time.
The following screenshots are from the original project page and illustrate the application’s historical interface and reporting features.
The overview screen presented tracked profile information in a central dashboard.

The contact interface provided a way to organize profile entries within the application.

The comparison view was designed to help examine differences between recorded account activity patterns.

The timeline presented historical observations in chronological order, making activity patterns easier to review.

The statistics screen summarized collected observations and provided another way to review activity data.

WhatsSpy Public used a web interface that could be pinned to a mobile device’s home screen. The original project described this as a browser-based experience rather than a dedicated Android APK.

This screenshot shows an external WhatsSpy Public installation pinned to an Android device’s home screen.

The original documentation described three deployment approaches for WhatsSpy Public:
The project documentation also provided installation demonstrations, update notes, and a discussion of the QEMU setup. However, WhatsSpy Public is an old project, and its compatibility with current WhatsApp services, operating systems, and dependencies should not be assumed. Consult the archived project resources before attempting to reproduce its research environment.
WhatsSpy Public highlights an important security lesson: information that appears harmless in isolation can reveal sensitive behavioral patterns when collected over time. Online activity indicators, profile changes, and timestamps may expose routines or availability.
Any reproduction of this research should use consenting test accounts and an isolated environment. Do not use the project to monitor another person’s account, collect their activity without permission, or distribute profile data. Modern WhatsApp behavior and privacy protections may also differ substantially from those examined by this historical proof of concept.

The original WhatsSpy Public project and its historical documentation were hosted on GitLab. Availability of the repository, installation files, and supporting resources may have changed.
