Sealcloak vs LockMyPix: which LockMyPix alternative is more private?

The two apps in one table

LockMyPix details are from its Google Play listing and data safety section, November 2026.

LockMyPix's strengths

LockMyPix deserves credit for being upfront about encryption. Plenty of "vault" apps only move files to a hidden folder, which anyone with a file manager or a computer can browse. LockMyPix encrypts them, and it has won an ePrivacy App Seal and good press coverage over the years.

It's flexible, too. You can unlock with a PIN, a password, a pattern, your fingerprint or your face, so you can choose whatever suits you. It supports SD cards, which helps on phones with little internal storage, along with albums and sub-albums, a decoy vault with its own code and intruder detection.

Sealcloak's approach

Sealcloak deliberately offers fewer ways in. The vault opens with a pattern on a 5×5 grid; fingerprint or face unlock can be added for speed, but the pattern always works and is what the encryption key is made from. Argon2id turns that pattern into the key, which makes each guess slow and expensive, and after four wrong attempts Sealcloak adds growing waits that resetting the clock won't skip.

Where the apps really part ways is the internet. Sealcloak ships without Android's internet permission, so it has no ads, no analytics and no way to send anything anywhere. It never asks for an email. The Coerce decoy vault can, if you choose, also erase your other vaults when it's opened, which is off by default and needs you to type PERMIT to turn on.

AES-CTR and AES-GCM in plain words

Both apps use AES, the same cipher banks and governments rely on. The mode is the part after the dash. CTR mode keeps files secret, but on its own it doesn't notice if an encrypted file has been altered or damaged; apps that use it need a separate check for that. GCM mode keeps files secret and also includes a built-in seal, so if even one byte of an encrypted file changes, decryption fails instead of quietly producing a broken or tampered file.

Sealcloak uses AES-256-GCM for every file, and each vault has its own random master key protected with help from the Android Keystore. Neither choice is something you'll notice day to day; it matters for how robust the vault is when something goes wrong. More in how Sealcloak's encryption works.

Backups and new phones

Moving to a new phone is where vault apps are tested. With Sealcloak, you make an encrypted backup by hand or on a weekly or monthly schedule, copy the file to the new phone, and restore it with your recovery phrase or the backup's passphrase. Nothing depends on an account or a server still existing. With any vault, test a restore once before you need it.

What each app knows about you

Google Play's data safety section is where developers declare what an app collects and shares. LockMyPix lists device or other IDs shared for advertising or marketing, and optional email, crash logs and diagnostics collected. None of that includes your photos, which stay encrypted, but it does mean the app communicates with outside services.

Sealcloak declares no data collected and no data shared. Because it has no internet permission, that isn't just a policy; Android itself stops it from connecting. Read Sealcloak's security page for exactly how keys and files are handled.

From LockMyPix to Sealcloak, step by step

1. Install Sealcloak, set your pattern, and copy the 9-word recovery phrase onto paper.
2. In LockMyPix, open your albums, select everything and export or unhide it to the gallery.
3. Add the files to a Sealcloak vault, keeping the same folder structure if you like.
4. Open a sample of photos and videos in Sealcloak to confirm they all arrived.
5. Delete the exported copies from the gallery, then empty the trash.
6. Clear your LockMyPix vault and uninstall it once you're happy.

Also check where your old files sat on the SD card; delete any leftover exports there too. Our guide to locking folders on Android explains why leftovers matter.

Final verdict

If you're choosing between these two, you're already choosing well: both encrypt. LockMyPix gives you more unlock options and SD card storage. Sealcloak gives you a vault with no internet access, no account and nothing shared, plus three independent vaults and the Coerce decoy. If you want the fewest moving parts between your photos and the outside world, choose Sealcloak.

Frequently asked questions

Is LockMyPix really encrypted?

Yes. LockMyPix's listing says it uses AES encryption rather than only hiding files, and it holds the ePrivacy App Seal. That puts it among the stronger vault apps.

Does LockMyPix need an account?

Its Play data safety section lists an email address as optional data collected for app functionality and account management, so an email is optional rather than required.

What's the main difference between LockMyPix and Sealcloak?

Both encrypt files on the phone and offer decoy vaults and intruder detection. Sealcloak has no internet permission and collects no data; LockMyPix's data safety section says it shares device IDs for advertising.

Can I use a PIN with Sealcloak like LockMyPix?

No. Sealcloak unlocks with a 5×5 pattern, with optional fingerprint or face unlock on top. LockMyPix offers PIN, password, pattern, fingerprint and face.
