TelemetryApp

TelemetryApp is an integrated data source (a Module) in UserSearch. It indexes public Telegram activity, letting you search messages, look up users and channels, and pull member lists and historic profile pictures. In UserSearch, TelemetryApp is the data source behind the Chat search type.

What TelemetryApp is

TelemetryApp is a Telegram-focused OSINT data source. It works against public Telegram channels and groups — the messages, memberships and profile artefacts that are openly visible — and makes them searchable by identifier. That makes it the reference source when your starting point is a Telegram username, a channel, or a piece of text you expect to find in public Telegram traffic, and you want to see where it appears and who is behind it.

What it returns

When you run a Chat search, TelemetryApp supplies Telegram intelligence such as:

• Message search across public channels and groups — find posts matching your query text
• Channel member lists — the visible membership of a public channel
• User lookup — profile detail for a Telegram user
• Channel lookup — profile detail for a Telegram channel or group
• Historic profile pictures — previously used avatars for a user

Draft — awaiting confirmation

The exact coverage (which channels and groups are indexed, and how far back), how often the index is refreshed, and whether a Chat search reads an existing index or queries Telegram live at run time are not yet confirmed. Treat the field list above as the general shape of what TelemetryApp returns, not a guaranteed per-result schema. These specifics await confirmation against the product.

Which UserSearch search types use it

TelemetryApp powers the lead Module of the Chat Messaging search type. At v2.0.20 the Telegram Chat Messages Module is labelled Data: TelemetryApp on its tile; the data sources behind the other four Telegram Modules are not shown on screen, so whether TelemetryApp also backs them is unconfirmed. All five query Telegram through a different lens each time:

Chat Module	What you look up
Telegram Chat Messages	Messages across public channels and groups matching your query
Channel Full Member List	The visible member list of a public channel
User Lookup	Profile detail for a Telegram user
Channel Lookup	Profile detail for a Telegram channel or group
User Historic Pictures	Previously used profile pictures for a user

All five Modules target the same platform (Telegram), so switching Modules changes the query shape and the input field. Only Telegram Chat Messages has a confirmed data source (TelemetryApp) — do not assume the other four share it.

Draft — awaiting confirmation

Only Telegram Chat Messages explicitly shows (Data: TelemetryApp) in the product. The other four Telegram Modules are documented here as sharing the same data source; that mapping awaits explicit confirmation.

How to access TelemetryApp in UserSearch

1. Select the Chat search type.
2. Pick the Module that matches your starting point — for example Telegram Chat Messages for text search, or User Lookup for a specific Telegram user.
3. Enter your target (for Telegram Chat Messages, the text you want to find; for the lookup Modules, a username or channel).
4. Confirm the Cost per search shown on screen before you run.
5. Select Search Now.
6. Review the results. Any matches are marked Found, and the Data Source column shows TelemetryApp.

Reliability note

Draft — awaiting confirmation

What is solid: UserSearch integrates TelemetryApp as a data source, and it is the source behind the Chat search type’s Telegram Modules. Data-source behaviour details — the breadth of indexed channels and groups, historical depth, refresh cadence, and whether results reflect a cached index or a live Telegram query — have not been confirmed and should not be treated as fact until verified. No official public site for TelemetryApp has been confirmed.
