If a person left WhatsApp - briefly?
If a person leaves WhatsApp, their profile and messages will still be visible to others in the chat, but they will no longer receive updates or notifications from the group.
If a person left WhatsApp - in detail?
If a person leaves WhatsApp, several changes occur that affect both the user's experience and their interactions with others. Firstly, all personal data associated with the account is removed from WhatsApp's servers, ensuring privacy and security. This includes messages, photos, videos, and any other media shared through the platform. However, it's important to note that backups stored on external services like Google Drive or iCloud will not be automatically deleted. Users should manually remove these backups if they wish to completely erase their data.
Secondly, the user's profile information becomes unavailable to other WhatsApp users. This means contacts can no longer see the person's last seen status, about section, or any changes made to the profile picture. Additionally, the individual will not appear in group chats they were part of, and their name will be replaced with "This person changed their phone number" if they were a contact of other users.
Thirdly, leaving WhatsApp does not automatically delete messages sent or received by the user. These conversations remain visible to other participants until manually deleted. If the user was the sole administrator of any groups, their departure may cause disruptions in group management unless another member is promoted to take over administrative duties.
Lastly, leaving WhatsApp does not prevent the user from returning at a later date. The account can be reactivated within 30 days after deactivation by simply verifying the phone number again. After this period, the account becomes permanently deleted, and all associated data is removed from WhatsApp's servers.
In summary, when a person leaves WhatsApp, their personal data is removed for privacy reasons, profile information becomes unavailable to others, messages remain visible unless manually deleted, and group management may be affected. The account can be reactivated within 30 days of deactivation.
