// FREQUENTLY_ASKED_QUESTIONS

>[Closed]How accurate is the detection?

Apple's SensitiveContentAnalysis framework delivers 99%+ accuracy with <1% false positives. Your beach photos and medical images won't get flagged.

>[Closed]Does it upload photos to the cloud?

Never. All analysis happens on your device using Apple's Neural Engine. Zero network requests, zero cloud uploads.

>[Closed]How fast is the scanning?

~1 second per photo on modern devices (A15+). Accuracy is never compromised for speed.

>[Closed]Is the vault secure?

ChaCha20-Poly1305 encryption with 256-bit keys stored in the iOS Secure Enclave. The vault is protected by FaceID / TouchID.

>[Closed]What happens to flagged photos?

Nothing happens automatically. You review all detected content and decide what to do. No photos are ever deleted or secured without your explicit approval.

>[Closed]Is the source code available?

Yes. The core privacy features, including the cryptographic operations for the vault, are open source on GitHub for public auditing.
