- People keeping sensitive files across personal devices
- Worth noticing
- Pairing uses an eight-digit code; devices need the same Wi-Fi, while off-site transfers use encrypted files that expire after 14 days.
Field notes
Device pairing uses an eight-digit code and is capped at five devices. The app's listed protections include Argon2id with 256 MB of memory, XChaCha20-Poly1305 for document encryption, and a 50-version history per document; deleted items can be restored from the trash for 30 days. iPhone/iPad and Windows versions are listed as available, while the Mac release is still being prepared.
