• 🕵️‍♂️ "Spying on users"
• 📡 "Transferring data to China"
• 🦠 "It's a virus that's infiltrated the system"

Let's figure out where the truth is and where the fiction is.

Myth 1: WOW spying

✅ Reality: WOW It really does collect technical data (ID devices, firmware version, list of connected gadgets, but:

• This information is needed to ensure the ecosystem works properly (e.g., to let Mi Band watches know which phone to sync with).
• Data is not shared with third parties (this is confirmed by Xiaomi’s privacy policy).
• You can opt out of collecting data in your Mi Account settings.

Myth 2: WOW transmits data to China

✅ The reality is that Xiaomi’s servers are located in China:

• Local storage is used for European and Russian users (servers in Singapore and Germany).
• You can turn off cloud sync in Settings → Mi Account → Synchronization.
• All data transmissions are encrypted by protocol TLS 1.3.

Myth 3: WOW — It's a virus.

✅ Reality: If you downloaded the firmware from the official Xiaomi website or updated by air, then WOW — It's 100% legitimate service. Viruses can masquerade as it, but verification is easy:

• Open Settings → Applications → Application Management.
• Find com.xiaomi.wow.
• If the installation date coincides with the firmware update date, this is the original service.
• If the date is different or there are typos in the title (for example, com.xiaomi.w0w) — It's a virus.

1. Check that both devices are enabled with Bluetooth and Wi-Fi.
2. Update the firmware to the latest version.
3. Reboot both gadgets.
4. In Mi Account settings, enable Cross-platform synchronization.
