Proxytale tells you next to nothing: high speed, several devices, three free days, done. Judging by the bot's handle it may be a proxy for Telegram itself, but the service never says so outright.
The profile lists no commands and no mini app, so you'll be figuring things out as you go, seeing what the bot offers after you start it. For a service that calls itself a benchmark of privacy, that's oddly tight-lipped.
If it really is a proxy, the difference from a VPN matters: a proxy usually helps one specific app rather than the whole phone. Your browser and other programs would then carry on unprotected. Worth finding out before you pay.
The three free days are a fair way to check all this. How many devices a subscription covers and what it costs aren't stated, only that it can be more than one.
The service has a news channel; no website, support contact or documents appear in the description. If something goes wrong, it looks like you'll be asking through the bot itself or the channel.
