When you make international calls on WhatsApp, the platform processes data related to the destination country and network to determine calling rates (if not free VoIP). This ensures accurate billing for any associated charges. This data is purely operational for service provision and does not involve the content of your call.
Data in Shared Contacts
When you use the "Share Contact" feature, you transmit contact data (name, phone number) to the recipient. This data is handled through the encrypted chat. WhatsApp whatsapp data facilitates this exchange, processing the contact information for delivery to the intended recipient within the secure communication channel.
Data for Archiving All Chats
WhatsApp allows you to archive all chats simultaneously. This action stores a system-wide preference as data, moving all your current conversations to the archived section. This function helps you achieve a clean chat inbox quickly, managing your communication history in bulk, rather than individual chat by individual chat.
