Umbra vs Gallery Vault
"Gallery Vault" is a whole category of Android apps that put a PIN in front of your hidden photos. Some genuinely encrypt. Many just move files into a hidden folder and gate the app with a password. The difference is everything.
The question to ask any vault app
Before you trust a vault with anything sensitive, ask one thing: if someone copies the app's files off my phone, can they open my photos?
- If the answer is "no, they're encrypted" - good. That's a real vault.
- If the answer is "yes, they're just in a hidden folder" - the PIN only protects the app's front door, not the files.
A lot of free gallery-lock apps are the second kind. They look the same from the outside, which is exactly the problem.
| What to check | Typical gallery-lock app | Umbra |
|---|---|---|
| Files encrypted on disk | Often not - just hidden | Yes - AES-256-GCM |
| Key derived from your pattern | Varies | Yes |
| Ads / trackers | Often ad-supported | No internet permission |
| Decoy vault | Rare | Yes |
| Intruder / failed-attempt log | Sometimes | Yes |
Why "no internet permission" is a useful filter
Many free vault apps are monetised with ads, which means they need network access - and network access means your usage, and sometimes more, can leave your phone. Umbra doesn't request internet permission at all. That single fact rules out ad networks, analytics uploads, and silent syncs by design, not by promise.
Choose a vault that actually encrypts
Umbra uses AES-256 with a pattern-derived key, no ads, and no internet permission. Your files are unreadable off-device.
Bottom line
The name "Gallery Vault" tells you what an app wants to be, not what it does. Check for real encryption, a separate key, and no network access. Umbra was built to pass all three - which is why we're comfortable putting the comparison right here.
