Security Architecture Breakdown

How CapsuleIt guarantees total data isolation, offline key derivation, and zero leakage.

🛡️

Your Keys Never Leave Your Device

CapsuleIt relies on local AES-256 GCM (Galois/Counter Mode) cryptography. When you lock a capsule with a custom passphrase, key derivation occurs inside local device memory. No secret keys or unencrypted payloads are transmitted across networks.

🔑 Client-Side AES-256 GCM

Authenticated encryption guarantees both confidentiality and ciphertext integrity against tampering.

💾 Local Hive Database Storage

Capsules are written to encrypted local Hive storage partitions in the Android hardware keystore.

🎯 Scoped Location Permissions

ACCESS_FINE_LOCATION is requested ONLY when explicitly interacting with geo-locked capsules.

📦 Encrypted Bundle Exports

Offline .tcapsule bundles allow zero-cloud peer-to-peer file transfers securely.

Frequently Asked Questions

Everything you need to know about CapsuleIt cryptography, tokens, and delivery.

Because CapsuleIt uses true zero-knowledge AES-256 GCM encryption, your passphrase is never sent to any server. If you lose your custom passphrase, the capsule cannot be decrypted. We recommend saving master keys in a password manager.
Yes! CapsuleIt is an offline-first app. All capsule timers, encryption operations, and local vault databases function 100% offline without needing an active internet connection.
When creating a Geo-Locked capsule, you set target GPS coordinates. The recipient's device monitors proximity locally (using distanceFilter: 3m). As soon as the recipient walks within 100 meters of the target location, the status flips to Unlocked.
Free users start with 500 welcome tokens. Certain actions like custom passphrases (15 tokens) or Telegram Bot delivery (20 tokens) consume tokens. You can earn +10 tokens anytime by watching a short video ad, or upgrade to CapsuleIt Pro for 0 token cost and zero ads!
You can export an encrypted .tcapsule package and send it anonymously via @CapsuleItBot to friends or groups. The recipient can import the file into their CapsuleIt app to unlock it when the timer or geo-fence condition is met.
