⛔️ Swiftgram’s possible tracking

One of Swiftgram’s (unofficial Telegram client) feature is to show users’ registration date.

But when it sends request to fetch this registration date, it also includes current user’s payload (identifier of Telegram account) and device’s unique ID in request (and the last one passes only in this request!)

1. With first parameter (user’s payload) they can track which profiles did you open.
2. With second parameter (device’s unique ID) they can track all of current user’s accounts and link them.

UPD: Swiftgram's official response — link

Anyway, be careful using unofficial Telegram clients and configure them correctly.
