Build privacy-first apps for TitanOS.

Bring your existing Android apps, or build native. The TitanOS SDK gives you security primitives, a hardened runtime, and a distribution channel that respects your users.

Quick start

Built on familiar foundations.

If you've shipped an Android app, you already know most of the API surface. Bring your existing code — extend it with TitanOS security primitives.

SecureMessenger.kt · TitanOS SDK
// Import the TitanOS security SDK
import os.titan.security.SecureChannel
import os.titan.crypto.HybridKEM

class SecureMessenger {

  fun send(peer: String, message: String) {
    // Negotiate a post-quantum hybrid key
    val key = HybridKEM.negotiate(peer)

    // Encrypt and attest on-device
    val channel = SecureChannel.open(peer, key)
    channel.send(message, attest = true)
  }

Port your Android app

Most Android apps run on TitanOS with minimal changes. Our porting guide walks you through the security review and submission workflow.

Porting guide

App Store submission

Our vetting process keeps trackers and unsafe code off user devices. Clear guidelines, fast reviews, privacy-first by default.

App Store principles

Three rules. No exceptions.

01

No trackers

Apps cannot ship third-party tracking SDKs, fingerprinting libraries, or behavioural analytics.

02

No data mining

User data stays on the device unless explicit, informed consent is given. Data-mining apps are rejected.

03

Transparent permissions

Every permission must be justified. Permissions you don't use, you don't get to request.
