Help with Datum
Good questions.
Useful answers.
What is free?
Password-based text encryption and decryption, passphrase generation, copying, sharing, clearing controls and the security guide are free.
What does Datum Pro include?
All container operations require a one-time Datum Pro purchase: creation, listing, management and deletion, import and export, encryption and decryption including recovery, and two-passphrase mode. The approved US base price is $5.99; Apple shows the price for your region. There is no subscription.
What is a container?
A container is a portable secret used with a separate strong message passphrase. Creating one requires a drawing that contributes to generation alongside operating-system randomness. Share protected container exports and message passphrases securely.
How do I back up or transfer a container?
With Pro, export a protected .datumcontainer file using a separate export password, and keep a copy somewhere safe. Import it on the other device with that password. You also need the separate message passphrase to open a message.
What if I lose a passphrase or container?
Lost container copies or passphrases can make messages unrecoverable. Opewell cannot recover them. Keep secure backups and credentials separately. Restoring a purchase does not restore lost data or passphrases.
What if Pro is unavailable?
Existing containers remain stored, but all access, including recovery and deletion, requires Pro. Restore Purchases using the Apple Account used for the purchase. Free password mode remains available.
How does two-passphrase mode work?
With Pro, two messages can be stored in one common fixed-size container packet. Each has a different passphrase; entering one opens only its matching message. Both recipients need the container.
What happens to copied text?
Clipboard copies expire locally after 60 seconds, but other apps may retain copies. Clearing or backgrounding the app does not guarantee erasure of external copies or all system memory.
Does Datum use a PIN?
No. Datum uses message passphrases and, for protected exports, a separate export password.
Still need a hand?
Include the app name and version, device model, iOS, iPadOS or macOS version, reproduction steps, and exact error or observed behavior. Send redacted screenshots or documents only if needed to explain the issue; never send passwords or sensitive originals.
