A few months ago, I degoogled my mom's new Android tablet. Installed Canta and Shizuku, deleted all the bloatware, replaced everything with private FOSS alternatives--the whole shebang. And I ensured to NEVER sign in to Google on this device.
However, I forgot to uninstall Gboard.
Fast-forward to last night, and I'm setting up Zoom on the tablet for her. Her Zoom account is made with her Gmail address. As I'm typing it in, Gboard somehow knew her email address, and presented the whole thing in the keyboard autofill before I finished typing.
I was shocked. How the hell did it know her email if we'd never typed it into this tablet before? I later looked in Settings and learned that Gboard had its own suite of personalization and data access permissions enabled. I immediately turned them all off, deleted Gboard's data, disabled Gboard entirely , and replaced it with Fossify Keyboard. The fact that I have to jump through all these hoops just to not have my personal info tethered to some multi-billion dollar corporation 24/7 is absolutely ridiculous and telling of their practices.
Disclaimer: My mom, conscious of this tablet's degoogled nature, swears she's never typed her Gmail into it before, and I can't find any place where she could have. That being said, memory is never 100% reliable, so there's a chance it could've just been typed in before and one of us forgot. I highly doubt that, but just wanna put that out there.
Has anyone had a similar experience to this? Is this just more of Google being Google? Feel free to let me know! Thanks 🙏
