One ecosystem, or four platforms
Trustful runs on iPhone, iPad and Mac, synced through iCloud, and nowhere else.
The moment a Windows laptop or an Android phone enters the picture, Trustful isn't there. Vaultine encrypts the same way on Windows, macOS, iOS and Android, so the vault isn't a decision you make per device: it's the same vault, wherever you open it.
Whose cloud holds the backup
Trustful's sync runs through iCloud, which means your encrypted files live on Apple's infrastructure and follow your Apple ID. You can't choose a different cloud.
Vaultine doesn't pick your cloud for you. Files are encrypted with AES-256-GCM on the device first, and if you turn on backup, they go to a Dropbox account you connect yourself — already encrypted before it leaves the device, so Dropbox holds data it cannot read. We hold no keys either way, which is what zero-knowledge means here: nobody but you can decrypt your files, including us.
A decoy account, or two prepared answers
Trustful's decoy account opens with a separate PIN and shows a different set of photos.
Vaultine splits this into two purposes instead of one. The Decoy Vault does the same job: a second code opens a vault you stocked in advance with harmless files. The Duress Vault goes further — a third code opens an empty vault and wipes your real ones as it does, becoming your only vault from that point on, for the moments when hiding files isn't enough and they can't be allowed to survive. Both are deliberate, configured in advance, and yours to set up exactly how you want.
What the subscription actually costs
This is where the two apps stop being close. Trustful's premium subscription is $9.99 a month or $29.99 a year, and its lifetime license is $399.
Vaultine's Pro tier is $1.99 a month, $14.99 a year, and $39.99 for a lifetime license that never expires. For the core promise both apps make — your files encrypted, on your terms — Vaultine's lifetime price is a tenth of Trustful's, and its free tier stays a real encrypted vault rather than a preview of one.
