PhotoCryptBurn

Complete Offline Local Operation
No remote server backend whatsoever. All encryption and decryption computations run entirely locally on your Android device. Zero data transmission, zero network uploads, keeping your private photos completely isolated.
Absolute Zero Data Collection
We do not collect, store, back up, or upload any of your personal data — including photos, passwords, viewing records, and device information. Your privacy is fully controlled only by yourself.
Ultra-Clean Third-Party Dependencies
Only Google’s official payment interface is integrated for in-app purchases. No advertising, analytics, tracking or other redundant third-party SDKs are included, eliminating potential privacy backdoors completely.
Industry-Leading Military-Grade Security System
Private Local Mode — Hardware-Level Encryption Protection
Adopts standard AES military-grade encryption, combined with native Android Keystore hardware encryption.
Encryption keys are securely isolated and locked in the device hardware security module, which cannot be extracted or cracked by any means.
Paired with a multi-layer honeypot defense mechanism, it effectively resists brute-force cracking and reverse engineering attacks, reaching the highest civilian security standard.
Shared Encryption Mode — Full Military-Grade Encryption Enabled
Even for photo sharing scenarios, we still adopt AES military-grade encryption strategy without compromise.
All shared encrypted files adopt exclusive proprietary encryption format. They can only be decrypted and viewed by entering the correct password within this app. No system gallery or third-party software is able to parse, decode or break the encryption.
Exclusive Closed-Loop Encryption Mechanism
All encrypted photos are encoded with a dedicated private algorithm.
Strict app-bound decryption: only this app with the correct password can unlock the files. All external tools are completely unable to access your encrypted privacy content.
Fine-Grained Encryption Access Control
Customize flexible security rules for your encrypted photos freely:
Set valid expiry period: encrypted files auto-expire and become unrecoverable when time is up
Custom preview display duration: auto-close preview to avoid peeking by others
Limit available decryption times: files lock automatically once reaching the maximum allowed unlock count
All-Round Anti-Disclosure Protection
Built-in system-level privacy protection:
Full screenshot, screen recording and screen projection blocking on all encrypted viewing pages. Effectively prevent privacy leakage through recording or screen capture.
Friendly Reminders
The app works fully offline with no cloud backup service. Please keep your encryption password properly; lost passwords cannot be retrieved.
Do not modify the format of encrypted files with third-party tools, to avoid file damage or decryption failure.
