In group video calls, WhatsApp processes data related to participant management, including who joins, leaves, and who is speaking. This data helps facilitate the multi-person video interaction and ensures proper routing of audio and video streams. While the content is encrypted, this management data is crucial for the call's functionality.
Data for Sticker Suggestions
WhatsApp may use data about your frequently used words or chat context to provide sticker suggestions. This data analysis occurs on your device, respecting encryption. This enhances the user whatsapp data experience by offering relevant stickers, making it easier to express yourself visually without searching through your entire collection.
Data for Two-Step Verification (PIN)
If you enable Two-Step Verification on WhatsApp, you create a six-digit PIN. This PIN data stores securely on WhatsApp's servers and is required when registering your phone number again. This adds an extra layer of security, protecting your account from unauthorized re-registration even if someone gains access to your SIM card.
