Privacy Policy

Last updated: July 14, 2026

1. Our Privacy Commitment

Lucive is built with privacy as our foundation. Your journal entries are your most personal thoughts, and we've designed every aspect of our service to ensure they remain completely private. Whether you're using Lucive on your Mac or iPhone, your data stays under your control.

Lucive now has two clearly separated halves, with different privacy designs on purpose:

2. How Lucive Works

Local-First Architecture

Platform-Specific Storage

3. Optional Sync Service

If you choose to enable device synchronization, here's what happens:

What the Relay Server Sees

What the Relay Server Doesn't See

How Device Pairing Works

  1. Generate a QR code on one device containing a temporary pairing secret
  2. Scan the QR code with your other device
  3. Both devices derive a shared encryption key
  4. All future communication is end-to-end encrypted
  5. The relay server only facilitates the connection—it never has access to your encryption keys

4. Optional: Lucive Account and Planning Cloud

Planning works entirely on your device with no account. If you want your plan on multiple devices, or you want to connect an AI assistant to it, you can create a Lucive account. Here is exactly what that involves:

What a Lucive account is

What the Planning cloud stores

Your control

5. Optional: AI Assistants and Agents

There are two separate ways an AI assistant can work with Lucive, with different privacy properties:

Planning: connected assistants (Claude, ChatGPT, and others)

With a Lucive account, you can connect an assistant to your Planning data through the Lucive plugin or connector. Connecting uses the same email-code sign-in as the app, and each connection gets its own revocable authorization.

Journal: the local MCP server

Separately, Lucive ships with an optional local Model Context Protocol (MCP) server for your Journal. With it enabled, an AI agent running on the same machine (such as Claude Desktop or OpenAI’s Codex CLI) can search, read, and write entries in your journal through the live Lucive app. This feature is off by default, works only on your own machine, and is unrelated to the Planning cloud: it exists precisely because Journal content never goes through any server.

What stays the same when MCP is on

What changes when MCP is on

Your control

Full technical details are in our MCP documentation.

6. What We Collect

For the macOS and iOS Apps

For the Marketing Website (lucive.app)

For the Lucive Account and Planning Cloud (Optional)

For the Journal Sync Service (Optional)

7. What We Don't Collect

We explicitly do not collect:

8. Data Security

Encryption Standards

Infrastructure Security

9. Third-Party Services

Required Services

Optional Services (Only if you enable Journal sync)

Optional Services (Only if you create a Lucive account)

For Purchases (macOS version)

10. Data Retention and Deletion

Your Journal Data

Sync Service

Lucive Account and Planning Cloud

Purchase Records

11. Children's Privacy

Lucive doesn't knowingly collect data from children under 13. The app is a general-purpose journaling tool without age-specific features or content.

12. Your Rights

You have the right to:

13. Changes to This Policy

We may update this privacy policy to reflect changes in our practices or legal requirements. We'll notify you of significant changes through:

Summary

Your privacy is paramount. Lucive is designed so that your journal entries never leave your control. Even when using our optional sync service, we use end-to-end encryption to ensure that only you can read your entries. We don't track you, we don't profile you, and we can't read your journal. Planning is different by design: if you create an account, the Planning data you sync is readable by our service so that your devices and the assistants you choose can work with it, and nothing more. Your thoughts remain yours alone.


This privacy policy is effective as of July 14, 2026 and applies to Lucive for macOS and iOS (currently in TestFlight beta), our Journal sync service, the Lucive account and Planning cloud, and assistant connections made through the Lucive plugin.
