Privacy Policy

Last Updated: September 2026

NexusTerm is designed with zero-tracking architecture. We do not collect, store, sell, or transmit your personal data, server configurations, or terminal contents to our own or third-party advertising servers.

1. Information We Store on Your Device

All data created inside NexusTerm is stored locally on your device:

Server Configurations: Hostnames, IP addresses, usernames, ports, and display preferences are stored locally in private application storage managed by iOS SwiftData.
Credentials & Keys: Passwords, private keys (Ed25519, ECDSA, RSA), and AI API keys are stored securely in the hardware-backed Apple Keychain and encrypted via Secure Enclave.
Known Hosts: Host key fingerprints for Strict Host Key Checking (TOFU) are stored locally on your device.

2. Data Transmission & Peer-to-Peer Networking

NexusTerm connects directly from your device to the remote servers you configure (SSH on port 22 or your designated custom ports). We do not operate relay, proxy, or intermediary servers. All terminal data and SFTP file streams pass exclusively between your device and your chosen remote endpoints using standard encrypted protocols (SSH-2 / SFTP / TLS).

3. Third-Party AI Services (Optional & BYOK)

If you optionally choose to enable the AI Command Assistant:

NexusTerm operates on a Bring-Your-Own-Key (BYOK) model. You provide your own API key for Google Gemini or OpenAI.
When you invoke an AI troubleshooting or command generation action, your prompt and relevant terminal context are sent directly to the selected AI provider's API.
NexusTerm incorporates an automatic client-side sensitive data redactor to mask passwords, IP addresses, and private keys prior to query dispatch.
We do not retain or log AI queries on any server. Queries are governed solely by the respective privacy policies of the AI provider you select (Google Privacy Policy or OpenAI Privacy Policy).

4. Analytics, Tracking & Advertising

NexusTerm contains no third-party tracking SDKs, no advertising frameworks, and no telemetry libraries. We do not track your usage habits or identify you across other apps or websites.

5. Your Rights & Data Deletion

Because all data is stored locally on your device, you have complete control over your data at all times. You can modify or delete individual servers, clear credentials in Settings, or remove all application data entirely by uninstalling the application from your device.
