About this app
Take back control of your digital life with Keychain, the secure password manager that puts your privacy first.
Keychain is built on a simple, powerful principle: **your data is yours**. All encryption and decryption happens exclusively on your device. We have no servers, we create no accounts, and we never see, store, or have access to your passwords. You are in complete control.
**Key Features:**
β **Total Data Control:** Keychain works with a single encrypted file that you manage. Create a new secure vault or open an existing one. Store it on your device, in your preferred cloud service (via the system file picker), or on a USB drive. You decide where your data lives.
π **Zero-Knowledge Security:** Your vault is locked with a Master Password that only you know. Because of our client-side design, password recovery is impossible. This is not a bug, it's a feature that guarantees no one but you can access your data.
π‘οΈ **Screenshot & Recording Protection:** To further protect your sensitive information, Keychain actively blocks screenshots and screen recording while you are viewing your passwords.
βοΈ **Full Password Management:** Securely add, edit, and delete login credentials. Store usernames, passwords, and private notes for all your online accounts.
π **Simple & Fast:** A clean, intuitive interface lets you quickly find what you need. Search your vault, copy credentials to the clipboard with a single tap, and lock your vault instantly.
π« **No Accounts, No Subscriptions:** Keychain is a one-time purchase. No recurring fees, no user accounts to manage, and no cloud dependency. Just simple, honest security software.

**Built on Proven Cryptography:**
We believe in transparency. Keychain uses industry-standard, open-source cryptographic principles to protect your data:
* **Encryption:** AES-256 (CBC Mode)
* **Key Derivation:** PBKDF2 with 310,000 iterations (SHA-512)
* **Authentication:** HMAC-SHA512 (Encrypt-then-MAC)
---
**Your Keys, Your Responsibility:**
Please be aware: If you forget your Master Password, your data will be permanently unrecoverable. This is the guarantee of our zero-knowledge security model. Please store your Master Password in a safe and memorable place.
