1. Zero-Knowledge Principle
Vault Core Architecture
Sentinel Base is designed so that only you have the keys to your data. To maintain this secure environment:
- We do not store your Master Password.
- We do not store your encryption keys.
- We cannot reset your password or access your vault.
2. Information Collection
Sentinel Vault (Identity Registry)
To facilitate account creation and secure multi-device syncing, we store minimal metadata:
- Email Address: Used as your unique account identifier.
- Authentication Proof: A cryptographically hashed version of your Master Password (via Argon2id). We verify you without ever seeing your password.
- Vault Blob: Your encrypted data, which appears as random noise to our servers.
3. Sentinel Dhikr Privacy Policy
Quran App Protocols
Spiritual Privacy Guarantee
Your worship is private. Sentinel Dhikr operates on a Strictly Local-First basis. Unlike the Vault, this application does not sync any usage data, reading habits, or tracking metrics to our servers.
- Local Bookmarks & Progress Reading history, Hifz (memorization) mode progress, and bookmarks are stored exclusively in your device's browser (IndexedDB). If you clear your browser cache, this data will be permanently deleted and cannot be recovered by us.
- Zero Analytics We do not use tracking cookies, Google Analytics, or any behavioral tracking software within Sentinel Dhikr.
- Content Integrity We utilize verified open-source datasets for Quranic text (Uthmani/IndoPak). We do not modify the sacred text. Users are encouraged to report any display anomalies immediately.
4. Storage & Security
Local Storage
Browser IndexedDB for offline-first performance across all apps (Vault, Dhikr, Planner).
Cloud Storage
Encrypted replication to secure DB nodes protected via TLS (SSL). (Vault Only)
We utilize Argon2id with per-user salting for key derivation to ensure maximum resistance against GPU brute-force attacks.
5. Rights & Liability
GDPR/CCPA: You have the right to access your registry (Email/Vault ID) or delete your account at any time. Warning: Deletion is permanent and unrecoverable.
Limitation of Liability: Sentinel Base is provided "AS IS". The developer is not responsible for data loss due to hardware failure, forgotten passwords, or unauthorized device access.
