Data and Privacy

This page is deliberately concrete. Sonar reads other people’s messages to find requests for you, so what it does and does not do should be readable in one sitting, not buried in clauses.

1. What Sonar reads

Public Telegram supergroups only. The same messages any of the group’s members can see. Nothing is read from private chats, from direct messages, or from groups our account was not admitted to.
Only the sources you connect. A chat is read because you added it to your niche, not because it exists.
Our accounts never write. They join as ordinary members and post nothing — no messages, no replies, no direct messages, no reactions. Read-only is a property of the system, not a promise about our intentions.

2. What Sonar stores

For a message that looks like a request in your niche: the text, the chat it came from, the time, a link back to the original, and the model’s verdict on why it is a lead. Messages that do not match are discarded — 90–95% never reach the model at all.

We do not build profiles of the people who write in those chats. There is no dossier: a lead is a message with a link, not a person with a history.

About you, the customer: your Telegram id and username, your niches, your connected sources, your plan and your usage counters. That is what the product needs to run.

3. How long

Leads are kept for the retention window of your plan — 30 days on Trial and Solo, 180 on Pro, 365 on Exclusive — and then deleted. Raw messages that never became a lead are not kept beyond the processing window.

4. Who else sees it

The language model. Message text is sent to a model to be classified. It is sent for a verdict, not for training.
Telegram. Alerts are delivered through the Telegram Bot API.
Nobody else. We do not sell data, do not share it with third parties and do not use it to advertise to anyone.
Other customers never see your leads. A chat may be watched for several customers at once; each one only ever receives what matches their own niche.

5. Your requests

Write to @SonarLeadSupport to get a copy of what we hold about you, to correct it, or to have your account and its data deleted. Deletion removes your account, your niches and your leads.

If you wrote a message in a public chat and do not want it stored as someone’s lead, write to the same address and it will be removed.
