If I deleted a number from my contacts, will this person still see me in WhatsApp - briefly?
If you delete a contact's number from your phone's address book, it will not affect their ability to see you on WhatsApp. Their visibility of your profile depends solely on whether they have saved your number in their contacts or not.
If I deleted a number from my contacts, will this person still see me in WhatsApp - in detail?
If you delete a contact's number from your phone's address book, it does not affect the visibility of your profile or status updates on WhatsApp for that particular individual. WhatsApp operates independently of your device's contacts list; it relies on its own database to manage and display user information.
When you delete a contact from your phone, the removal is limited to your local address book and does not transmit any changes to WhatsApp's servers. As a result, the person whose number you deleted will still see your profile picture, status updates, and any messages you send or receive within the app. This separation ensures that users maintain control over their contact lists on their devices without impacting their interactions within WhatsApp.
However, it is important to note that if you block a user on WhatsApp, they will no longer be able to see your profile picture, status updates, or any messages you send. Blocking is a more comprehensive action taken directly within the WhatsApp application and affects both parties' ability to communicate within the platform.
In summary, deleting a contact from your phone's address book does not alter the visibility of your presence on WhatsApp. The other person will continue to see you as they normally would within the app, preserving the integrity of your communication and interaction.
