One of the best Android accessibility features that hardly anyone knows about is Live Caption. It automatically captions any speech playing on your phone, including podcasts, video calls, audio messages, phone calls and videos. It’s remarkable.

Live Caption works on the Pixel 2 and up and other select Android phones. To turn it on and off:

• Press the up or down volume button.
• Under the volume controls, tap Live Caption.

Google says captions are processed locally, are not stored, and never leave your phone.

I don’t trust Big Tech and you shouldn’t, either. You’ve heard me say for years that free email services like Gmail or Yahoo aren’t really free. There’s a big price to pay — your privacy. These free email sites scan, analyze and save details of every email you send and receive, giving Big Tech a very intimate and detailed profile of you so they can easily sell your data to the highest bidder.

That’s why I use StartMail. With StartMail, I can send encrypted emails with one click, even if the recipient doesn’t use encryption. And StartMail never scans or analyzes your emails. Best of all, when you delete an email, it’s gone — forever.
