Sygen - Privacy Policy

Effective Date: May 8, 2026

1. Introduction

Sygen is a self-hosted AI agent platform developed by Time Design LLC. This Privacy Policy explains how the Sygen iOS application handles your data.

2. Self-Hosted Architecture

Sygen is fundamentally a self-hosted product. The Sygen iOS app is a thin client that connects to a backend server you (the user) host on your own infrastructure (Mac, Linux server, PC, NAS, VPS, or other private server). All conversations with AI agents, chat history, files, tasks, schedules, and any other content you create live exclusively on your self-hosted server. Time Design LLC does not collect, store, transmit, or have access to any of your application data.

3. Data Stored Locally on Your Device

The Sygen iOS app stores the following on your iPhone or iPad, locally only:

  • Authentication tokens (in iOS Keychain) — required to connect to your self-hosted server.
  • App preferences (in iOS UserDefaults) — UI settings such as filter selections, pinned chats, view modes, and language preference.
  • Media cache — images, voice messages, and files transferred during chats are cached locally for performance. These are also stored on your self-hosted server.

This data never leaves your device unless you explicitly send it to your self-hosted server.

4. Network Communication

The Sygen iOS app communicates exclusively with the self-hosted server URL you configure. All network communication uses HTTPS / TLS. The app does not contact any Time Design servers, analytics providers, ad networks, or third-party SDKs that collect personal data.

5. AI Service Providers

When you chat with an AI agent through Sygen, your self-hosted server may forward your messages to third-party AI providers (such as Anthropic Claude, OpenAI, or others) on your behalf, using API keys you configure on your self-hosted server. The Sygen iOS app itself does not directly contact these providers — the relationship is between you, your self-hosted server, and the AI provider you choose. Please refer to the privacy policy of the AI provider you use for details on how they handle your data.

6. Permissions

The Sygen iOS app requests the following iOS system permissions:

  • Microphone — for voice messages in chat. Recordings are sent to your self-hosted server only.
  • Camera — to capture photos directly inside chat. Photos are sent to your self-hosted server only.
  • Photo Library — to attach existing photos to chat messages, or save chat images you receive. Read and write are local to your device.
  • Face ID — to unlock the app and protect your operator session. Face ID data never leaves your device (handled by Apple's Secure Enclave).

You can revoke any permission at any time in iOS Settings → Sygen.

7. Tracking and Analytics

The Sygen iOS app does not track users, does not use the iOS App Tracking Transparency (ATT) framework, does not integrate any analytics SDK, and does not share any data with advertising networks. The app's privacy manifest (PrivacyInfo.xcprivacy) declares NSPrivacyTracking = false and an empty NSPrivacyCollectedDataTypes list.

Required-reason APIs declared in the manifest are limited to UserDefaults (reason CA92.1) and File Timestamp (reason C617.1) — both of which operate inside the app container only.

8. Children's Privacy

Sygen is intended for users aged 4+. The app does not knowingly collect personal information from anyone, including children.

9. Data Retention and Deletion

Because Time Design LLC does not store your application data, there is nothing to delete on our side. To remove your data:

  • Locally: delete the app from your iPhone — all locally cached data is removed by iOS.
  • On your self-hosted server: manage your own data through the Sygen admin tools or directly on the server.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The effective date at the top of this page indicates when it was last revised. Significant changes will be communicated through the Sygen iOS app or via the email address associated with your TestFlight / App Store account, where applicable.
