Privacy Policy

Last updated: February 21, 2026

Overview

PasswordLock is an offline-first password manager. Your data never leaves your device. We do not collect, store, or transmit any personal information or usage data.

Data Collection

We do not collect any data. Specifically:

Local Data Storage

All data you create within PasswordLock — including passwords, notes, and account details — is stored exclusively on your device. Your data is encrypted using AES-256-GCM field-level encryption before being written to the local database.

Your master password is never stored directly. A cryptographic key is derived from it using PBKDF2-SHA256 with 600,000 iterations and used to encrypt and decrypt your vault.

Keychain Usage

PasswordLock uses the iOS Keychain to securely store encryption keys. The Keychain is a hardware-backed secure storage provided by Apple. These keys never leave the device's secure enclave.

Biometric Authentication

If you enable Face ID or Touch ID, biometric data is handled entirely by iOS. PasswordLock never accesses, processes, or stores your biometric data. We only receive a success or failure response from the operating system.

AutoFill Extension

The PasswordLock AutoFill extension uses an App Group container to share your encrypted vault between the main app and the extension. This data remains on-device and is never transmitted externally. The App Group identifier is group.com.sfmob.passwordmanager.

Third-Party Services

PasswordLock does not integrate with any third-party analytics, advertising, or data processing services. There are no SDKs that collect or transmit user data.

Encrypted Backups

If you use the encrypted backup feature, backup files are created locally on your device. You control where these files are stored or shared. We have no access to your backups.

Children's Privacy

PasswordLock does not knowingly collect any information from anyone, including children under the age of 13.

Changes to This Policy

If we update this privacy policy, we will post the revised version on this page with an updated date. Since we collect no data, changes are unlikely to affect your privacy.
