We're very sorry, but this means we must part ways here. Unlike others, we don't use your data for ad targeting or other commercial purposes. Telegram only stores the information it needs to function as a feature-rich cloud service. You can adjust how we use your data (e.g., delete synced contacts) in Privacy & Security settings. But if you're generally not OK with Telegram's modest requirements, it won't be possible for us to provide you with this service.
