Hide, Disguise, Protect - The Ultimate Privacy Vault Experience

🌟 Vault — Calculator Lock is a privacy and file protection tool developed by Luminous Organisation. It allows you to conceal photos, videos, audio clips, and sensitive notes behind a fully working calculator disguise.

You have complete control over your security layout. Protect your sensitive media behind a dynamic passcode or pattern, or launch into a secondary Decoy Mode to show off decoy content if anyone asks you to unlock your vault.
