CipherVault：安全加密器·照片视频加密解密工具 vs Privasa

CipherVault is a professional, secure, and fully local encryption and decryption tool that puts you in complete control of your privacy. It uses advanced, industry‑leading encryption algorithms to provide high‑strength protection for private photos, sensitive videos, and all types of important files. Unlike ordinary encrypted photo albums that only hide the entrance, CipherVault truly encrypts the original files into ciphertext – without the correct key, decryption is impossible. Encrypted files can be freely stored on your phone, computer, or in the cloud, or shared securely. You can also set multiple different keys to encrypt different files. All encrypted files cannot be opened or viewed directly; they must be restored using CipherVault and the correct key. Core Advantages: **Independent keys, flexible management Support custom, user‑defined keys, create multiple keys and set a default key at any time – different files can be encrypted with different keys. **Cross‑device freedom, seamless transfer The unique encryption format allows encrypted files to be securely transferred and decrypted across different devices. You can back up the ciphertext to your phone, computer, or cloud, then import it to any device when needed and decrypt it with your key. **Full format support, one‑tap encryption Whether it’s an image, video, or any other file, encryption can be done with one tap – no format restrictions. **Batch processing, high efficiency Encrypt or decrypt multiple files at the same time, greatly improving efficiency and saving time and effort. **Local, fast, and secure All encryption and decryption operations are performed locally on your device, with no data upload – ensuring both security and speed. Core Features: • Photo encryption: Batch‑encrypt photos into ciphertext to prevent unauthorised viewing. • Video encryption: Batch‑encrypt videos into ciphertext to protect private footage. • File encryption: Batch‑encrypt any files into ciphertext, covering documents, archives, and all other formats. • Decryption & restore: Verify the security key and restore the original content with one tap. • Double security lock: Enable “password + Face ID” double unlock in settings, adding an extra layer of security to your privacy. • Key management: Centrally manage multiple keys, assign different keys to different files for fine‑grained access control. **********Use Cases********** 1. Protect personal privacy Don’t want others to browse the private photos or videos on your phone or computer? Use CipherVault to encrypt them – only you can decrypt and view them, completely eliminating the risk of privacy leaks. 2. Safeguard important documents Confidential files such as contracts, ID documents, and financial records need strict protection. With CipherVault’s strong encryption, even if your device is lost or accessed by someone else, the file contents remain unreadable. 3. Secure transmission and sharing When sending sensitive files over the internet, encrypt them first with CipherVault, then send the ciphertext to the recipient. The recipient only needs the key you provide to decrypt and view them, preventing leaks during transmission. 4. Lock down cloud backups Upload encrypted files to cloud storage – even if the cloud provider is breached or your account is stolen, the other party sees only unreadable ciphertext, ensuring your cloud data is truly secure.

Privasa focuses on local data encryption protection and processes data in multiple dimensions to help secure your personal data. 1. All data stored locally, no cloud uploads The app never collects or uploads private content including notes, photos, audio, videos and check-in records to external servers. All files are saved in the app’s private directory inaccessible to other apps. Network requests are only triggered for in-app purchase verification and loading the privacy policy page, with no personal data transmitted. 2. Multi-layer local encryption protection All content is encrypted with AES-256-GCM. Encryption keys are derived from your custom password via PBKDF2 and stored securely in iOS Keychain. Temporary memory keys are cleared automatically when the device locks. Multiple accounts are supported with isolated independent encryption. 3. Biometric secure unlock Face ID and Touch ID quick unlock are available. Raw biometric data is managed solely by the system. This app only receives verification results and never accesses, stores or transmits biometric information. Rich Recording Features • Diverse text editing: journals, Markdown rich text and to-do lists for your moods and private thoughts; • Multimedia attachments: import gallery photos, capture images and record audio/video, all encrypted locally; • Check-in calendar view: track daily habits via timeline without third-party calendar sync; • Recycle bin for soft deletion: deleted items can be restored or permanently erased, still encrypted. Independent Data Management 1. Offline encrypted import & export: create local encrypted backups or import TXT, Markdown and your own encrypted files without internet; 2. Native system sharing: use iOS official share sheet to recommend journals to friends. Sharing is handled by the system, and the app will not upload materials; 3. Full data ownership: all local encrypted data is completely removed after uninstallation with no background backups retained. Additional Services • Multilingual interface: switch between Simplified/Traditional Chinese, English, Japanese, Korean, French and over 20 languages; • Compliant rating entry: built-in official Apple review pop-up to leave five-star ratings on App Store; • Minimal permissions: gallery, camera, microphone and biometrics are optional with no mandatory irrelevant permissions. Privacy Commitment This app does not collect device IDs, advertising IDs, location data, usage analytics or crash logs. No user data tracking or selling takes place.
