Privacy Policy

Last Updated: February 25, 2026

1. Introduction

Welcome to matriXdocs ("we," "our," or "us"). We are committed to protecting your privacy and complying with global data protection regulations, including the GDPR. This Privacy Policy explains how our application handles your data.

Core Principle: matriXdocs is designed with a Local-First Architecture. This means your data primarily resides securely on your own device, not on our centralized servers.

2. Data We Collect and Process

We do NOT collect, store, or sell your personal document data on our servers. Our architecture is designed to minimize data collection:

• Anonymous Device Identity: When you open the application, a random, anonymous Device UUID is generated to identify your installation for licensing and quota purposes. No personal registration is required.
• Local Personal Information: Your name, signature, and profile details are stored locally on your device (in your browser's secure local storage or native SQLite database).
• Documents & AI Processing: Any form or document you generate is processed securely. When utilizing AI features (via Gemini 2.0 Flash), we send necessary visual data to the AI model strictly for processing the current request. This data is not used to train global AI models.
• Payment Information: If you upgrade to a Premium/Regular subscription, transactions are processed securely by Stripe (supporting global methods like Alipay and WeChat Pay). We store your provided email address exclusively for sending receipts, linking your subscription to your Device UUID, and enabling account recovery. We do not store full credit card details.

3. Vanity Email Aliases (@matrixdocs.ai)

If you are a Premium user and reserve a custom Vanity Email Alias, we process incoming and outgoing emails routed through this address.

• Mapping: We securely map your chosen alias to your Device UUID in our routing backend (Cloudflare Workers).
• Ephemeral Processing: We do NOT store the contents of your emails permanently. Our servers act strictly as a secure pass-through router to deliver the documents to your local device inbox or dispatch them to your requested recipients.

4. Third-Party Services

We use the following trusted third-party providers to operate our application safely:

• Stripe: For secure payment processing and subscription management.
• Cloudflare: For secure API routing, rate-limiting, and managing the edge network for email aliases.
• Google Vertex AI: For multimodal document processing using Gemini.

5. Data Storage & Backups

Your data is yours. Because of our Local-First approach, we do not perform automatic cloud backups to our servers.

• All templates, documents, and settings exist locally on your device.
• You are responsible for backing up your data using the built-in "System Share" backup feature, which allows you to export an encrypted archive directly to your preferred secure location (e.g., local files, WhatsApp, iCloud).

6. GDPR & Your Rights

Under the General Data Protection Regulation (GDPR) and similar global privacy laws, we act as the software provider, while you are the sole data controller of the content you generate.

• Right to Erasure (Right to be Forgotten): You can instantly delete all your local data by clearing your browser cache or uninstalling the application from your device.
• Alias Data: You may request the unlinking or deletion of your Vanity Email Alias by contacting support.
