Privacy Policy

1. Introduction

Lexis is built on a fundamental belief: your data belongs to you. This Privacy Policy explains how Lexis handles your information. Lexis is designed as a local-first, non-profit productivity tool. We do not operate servers, maintain databases, or collect personal data.

2. Data Storage & Location

Everything is local. All data you create within Lexis is stored exclusively in your browser's IndexedDB and localStorage. This means:

• Your data never leaves your device
• No servers receive or store your information
• No accounts or cloud storage are involved
• Clearing your browser data will erase your Lexis workspace
• Exporting a backup is your responsibility (we provide the tools)

3. Optional Password Protection

Lexis offers an optional local password feature. This is entirely optional - you can use the full app without setting one. If you choose to set a password:

• The password is stored only on your device in localStorage
• It is never sent to any server or third party
• It cannot be recovered if lost - only your data can be preserved by resetting it
• It acts as a simple lock, not an account system
• You can reset it at any time from the lock screen

4. Noor AI & NVIDIA NIM

Lexis integrates with NVIDIA’s NIM API to power Noor, its built-in AI assistant. Noor offers three models - Ethos 1.5 (deep reasoning), Logos (balanced everyday intelligence), and Verse (fast, lightweight responses). When you use Noor:

• Your prompts and relevant context are sent to NVIDIA’s NIM API for processing
• This data is transmitted temporarily and is not stored by NVIDIA
• You can bring your own API key for full control
• AI features are optional - all core tools work without them

5. Voice Input & Speech Recognition

Voice dictation in Noor lets you speak to your assistant. When you use the microphone, your audio is recorded locally on your device and sent to NVIDIA's NIM API, where it is transcribed to text using Whisper (speech-to-text). Lexis does not store your audio recordings.

As with text input, this data is transmitted temporarily to NVIDIA for processing and is not stored by NVIDIA (see section 4). The transcribed text is handled exactly like text you type - it stays on your device and is only sent to NVIDIA's NIM API again when you choose to send it as a message to Noor. You can revoke microphone access at any time through your browser's site permissions.

6. Analytics & Tracking

Lexis uses zero analytics, zero cookies, and zero tracking. We do not collect, measure, or monitor how you use the application. There are no embedded third-party scripts, no analytics services, and no telemetry.

7. Third-Party Services

Lexis itself has no third-party dependencies that process your personal data. The only external service integrations are:

• NVIDIA NIM API - Powers Noor’s AI features (optional). See section 4 for details.
• Google Fonts - Loaded from the Google Fonts CDN for typography.
• NVIDIA NIM (Whisper) - Transcribes your voice when you use voice dictation. See sections 4 and 5.

8. Data Export & Deletion

Since we don't store your data, there's nothing for us to delete. You can export your entire workspace as JSON from the Settings page, or clear your browser data to remove everything. Individual notes can be exported as .docx files.

9. Children's Privacy

Lexis does not knowingly collect any personal information from children under 13. As no data collection occurs at all, there is no risk of inadvertent collection.
