It is good to know that your WhatsApp messages are automatically backed up & saved on your phone's memory. Therefore, if you want to delete WhatsApp from your phone and don't want to lose any of your messages, make sure to manually back up your chats before uninstalling.
To save your messages:
-Go to WhatsApp > Menu Button > Settings > Chat Settings
-Choose Backup Conversations
To export a copy of the history of an individual chat or group, you can use the Email Chat History feature:
-Choose and hold on the conversation or group.
-Choose Email conversation
-Choose whether to Attach Media or not.
After that, an email will be composed with your chat history attached as a .txt document.
If you choose to attach media, the most recent media sent will be added as attachments.
