OneRule

OneRule is a secure, modern, and offline-first password manager designed for users who want full control over their sensitive data.

Unlike cloud-based password managers, OneRule stores all passwords and secure notes locally on your device. Your data is never transmitted to any server, never synced to the cloud, and never shared with third parties. The app does not require an internet connection and works completely offline.

OneRule is ideal for users who value privacy, simplicity, and security without relying on accounts, subscriptions, or external services.

KEY FEATURES

• Offline-First Design
OneRule works entirely offline. The app does not request internet permission, ensuring your passwords stay only on your device.

• Secure Local Encryption
All stored data is encrypted locally using strong, industry-standard cryptographic algorithms. Encryption and decryption happen only on your device.

• Master PIN & Biometric Access
Access your vault using a 6-digit Master PIN. For convenience, biometric authentication such as fingerprint or face recognition can be enabled on supported devices.

• Panic Mode
Optionally set a Panic PIN. When entered, the app opens a decoy (empty) vault instead of your real data, helping protect your information in stressful or unsafe situations.

• Secure Backup & Restore
Export your encrypted vault as a local file and restore it on another device. Backups remain encrypted and under your control at all times.

• Screen Protection
Screenshots, screen recording, and app previews are blocked to reduce the risk of accidental data exposure.

• Password Organization
Organize your passwords into custom categories such as Work, Social, Finance, or Personal to keep everything structured and easy to find.

• Multi-Language Support
OneRule is available in English, Turkish, and German.

PRIVACY FIRST

OneRule is built with privacy as a core principle:
• No internet permission required
• No cloud synchronization
• No analytics or tracking
• No advertisements
• No account creation or login system

The app does not collect, store, or share any personal information.

IMPORTANT NOTES

Your Master PIN is used as part of the encryption process. If you forget your Master PIN, your encrypted data cannot be recovered by anyone, including the developer.

OneRule is intended for personal password management and secure storage of sensitive information.
