Ask HN: WhatsApp and Chat Export Options

Seems like a support question, but it's more than that.

Currently, WhatsApp allows users to export chat history in a .txt file for the latest 40,000 messages only. This limitation is rather arbitrary and annoying. Regarding this, I have two questions:

1. Is there any way to export my entire WhatsApp chat history, without rooting my Android phone?

2. Is this limitation even legally allowed? In other words, is WhatsApp legally obligated to allow me to export my entire chat history, under GDPR/CCPA/etc.? I'm guessing maybe not since this data lives on my device in encrypted sqlite files, and not on their servers. Am I right here?
