The disguise isn't the lock
A calculator disguise stops a casual glance. It won't stop someone who searches your App Store purchases, checks Settings → General → iPhone Storage, or sees you use it. When the disguise fails, all that's left is the encryption, and in this category encryption ranges from solid to missing.
How to check any calculator vault
- Does the listing say how files are encrypted, or only that they're "hidden"?
- Is there an ad SDK? Ads mean third-party code running inside your vault.
- What's the recovery process? Email resets mean the developer can get in.
