Search on Telegram is more powerful than in other messaging apps because it allows users to find public channels and bots. Unfortunately, this feature has been abused by people who violated our Terms of Service to sell illegal goods.
To further deter criminals from abusing Telegram Search, we have updated our Terms of Service and Privacy Policy, ensuring they are consistent across the world. We’ve made it clear that the IP addresses and phone numbers of those who violate our rules can be disclosed to relevant authorities in response to valid legal requests.
Decent counter-example. In turn I’d say that’s an edge case where we could still survive just fine without knowing the relevant fact for sure. And certainly not worth the cost in privacy terms of recording and storing everything.
There are a lot of things you can survive without :)) They are still nice to have though.
But I understand the privacy concerns, I struggle with the tradeoffs myself. But to me it’s worth it it this case since the database is supposed to be encrypted with a passphrase and stored locally, not sent over a network.
Other examples would include searching through history to check if you’ve talked to someone about something. Or check their answer. Unless you are someone with perfect memory I would think these are common situations.
