Can we not even trust Meredith & Signal? Although I wouldn't trust my phone - the place that displays all the data un encrypted, privacy sometimes feels unachievable when talking about electronic devices that connect to the Internet or even air gapped devices with that PowerHammer malware stuff 🥴

I don't know about Meredith but I wouldn't trust Signal or my phone 🤙
An air gapped wallet with hand written (or hand-hole-punched) data transfers should be pretty safe
