Backup & estate
Two encrypted files, same cryptography, different jobs: one for your own bad day, one for someone who has to open this without you.
Screenshots are from the iPhone app. The Android app has the same features, drawn in Android's own style.
Why there are two
People read the feature list and assume one of these is redundant. They are not:
| Encrypted backup | Estate Export | |
|---|---|---|
| For | You, on a new or wiped phone | Someone who inherits this |
| Opened with | Abditex Bullion | Any PDF reader, plus the passphrase |
| Assumes | You still have the app and the passphrase | Nothing — not even that the app still exists |
| Tier | Free | Pro |
Encrypted backup Free
More ▸ Backup ▸ Create backup. Choose a passphrase and save the file wherever you keep important things. The backup holds everything — holdings, Abdita, tags, photos, price snapshots — encrypted with your passphrase before it is written.
It is entirely on-device. No network call is made, and no copy goes to us.
Restoring on a new phone
- Install Abditex Bullion on the new device.
- More ▸ Backup ▸ Restore from backup.
- Pick the file and enter the passphrase.
There is no account to sign into, because there is no account. The file and the passphrase are the whole recovery story.
Lose the passphrase and the backup is gone
We cannot reset it, recover it, or help you guess it. There is no back door, and that is exactly why the file is safe to keep in cloud storage. Write it down and keep it somewhere separate from the backup itself.
Reminders Free and cloud destinations Pro
Backup reminders — "remind me every 30 days" — are free for everyone. They are a local notification your own phone schedules; nothing about them touches the network. We would rather every user backed up than earn anything from the ones who do not.
Pro adds where it goes: writing the backup straight to iCloud Drive or Google Drive instead of saving it by hand. The file is encrypted before it leaves the app, so your cloud provider stores something they cannot read.
Estate Export Pro
More ▸ Estate export. Produces a single encrypted PDF designed to be opened by someone who has never used this app, possibly years from now, possibly after we no longer exist. It carries a cover page explaining what the document is, and an embedded script that can recover the contents without any Abditex software at all.
The cover page is readable without the passphrase, deliberately. An heir who finds the file needs to know what it is and what to do; a completely opaque file gets deleted. The cover shows the document title, the export date, and the names of the Abdita included — so name your Abdita with that in mind. Your holdings themselves are in the encrypted portion and are not readable without the passphrase.
Give your heir the passphrase through a different channel than the file — a sealed letter with your will, an attorney, a safe. A passphrase stored next to the file it opens is not a passphrase.
What is never in either file
Your sharing identity keys and your demo-mode PIN are excluded from both. A restored backup is your inventory, not your device's cryptographic identity — which is why restoring does not silently reattach you to other people's shared Abdita.
