Overview

Arlo Lite ("we", "the app") is a free, open-source iOS application for interacting with large language models (LLMs). We are committed to protecting your privacy. This policy explains what data the app handles, how it is stored, and what is never collected.

Data We Do NOT Collect

  • We do not collect, transmit, or store any personal information on external servers.
  • We do not use analytics, telemetry, or tracking of any kind.
  • We do not have a backend server — there is no server-side component.
  • We do not access, read, or share your conversations with any third party.
  • We do not display advertisements.

Data Stored on Your Device

All data generated by Arlo Lite stays on your device:

  • Chat sessions — stored locally using on-device SQLite database.
  • API keys — stored exclusively in the iOS Keychain, Apple's encrypted credential storage. They are never written to plain text files or unencrypted storage.
  • Provider configurations — stored locally on-device (model selections, base URLs, display names).
  • User preferences — theme, language, system prompts, and other settings stored locally.

Network Communication

Arlo Lite communicates over the network only in the following scenarios:

  • LLM API calls — When you send a message, the app makes a direct HTTPS request to your configured LLM provider (e.g., OpenAI, Anthropic, or your custom endpoint). The content of your conversation is sent directly to the provider you chose. We have no involvement in this communication.
  • Model metadata — The app may fetch model pricing and context window information from a public CDN to keep model information up to date.

You are responsible for reviewing the privacy policies of your chosen LLM providers regarding how they handle your data.

iCloud Backup

If you enable iCloud backup in the app:

  • Chat session text and provider configurations (excluding API keys) may be backed up to your iCloud account.
  • API keys are never included in iCloud backups.
  • File/image attachments are not synced.
  • iCloud data is governed by Apple's privacy policy and your iCloud account settings.

Third-Party Services

The app does not integrate any third-party SDKs for analytics, crash reporting, or advertising. The only external services the app communicates with are:

  • The LLM providers you explicitly configure (OpenAI, Anthropic, or custom endpoints).
  • Apple's iCloud service (only if you enable backup).

Children's Privacy

Arlo Lite is not directed at children under 13. We do not knowingly collect any data from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be reflected on this page with an updated "Last updated" date. Since the app collects no data, changes are expected to be minimal.
