Please read Disclaimer, Is it legal ? and Are there any risk ?.
When the features become the weaknesses...
Nyx aims to highlight the weaknesses of instant‑messaging apps and increase public awareness of them. These common features allow malicious actors to perform reverse phone lookups and harvest personal data associated with a phone number. These data include :
- Username
- Photo
- Bio
- Last activity
- and more...

Yes, users can always change their profile visibility. To view or edit these settings :
- WhatsApp : Settings > Privacy
- Telegram : Settings > Privacy and Security
The possible potential risks, temporary or permanently :
- Restricted to use WhatsApp through another device, or Telegram API
- Account suspension via phone number
A reasonable reverse lookup frequency would be ;
| Telegram | |
|---|---|
| 4/day | 12/day |
Waiting at least a few seconds between each call, at an irregular frequency. Use a prepaid SIM card to prevent such situations.
It's legal to view publicly or freely available information, when the user is aware of this feature and consented to it. However, scraping would be considered a privacy violation in many jurisdiction (including EU and US), and would violate Terms of Use of WhatsApp and Telegram.
Doing so could result in a permanent suspension, and a criminal penalty.
Moreover, the constant storage of this data could be considered a privacy violation (mainly for EU). You might consider editing AUTOSAVE and manage your cache yourself.
You alone bear full responsibility for any misuse or damage resulting from the unauthorized or unlawful use of this project.
