1. 収集する情報

Account Information

When you create an account for the web app, we collect your name and email address through our authentication provider, WorkOS. This information is used to identify your account and manage your subscription.

License Keys and Billing

If you purchase a license for the desktop app or subscribe to a paid plan, we collect billing information through Stripe, our payment processor. This includes your payment method details, billing address, and transaction history. We do not store your full credit card number on our servers — Stripe handles all payment processing directly.

Usage Data

We collect anonymized usage data to understand how features are used and to improve the application. This includes:

Error reports are anonymized and do not contain your source code, file contents, or personal data. They include stack traces, error messages, and environment metadata to help us diagnose and fix bugs.

AI Chat Conversations

AI chat conversations are stored locally on your machine in the application data directory, organized per-project. These conversations are never sent to Backdraft servers. When you use the AI agent, your prompts and project context are sent directly from your machine to the LLM provider you have configured (such as Ollama, LM Studio, or OpenRouter). Backdraft does not intercept, proxy, or retain any of this communication.

Project Files

Your source code, project files, and all editing activity remain entirely on your local machine. Backdraft does not upload, copy, or transmit your project files to any Backdraft-operated server. All parsing, rendering, and code editing happens client-side.

2. 情報の使用方法

We use the information we collect for the following purposes:

We do not use your information for advertising, profiling, or any purpose unrelated to operating and improving the Service.

3. サードパーティサービス

Backdraft integrates with third-party services to provide its functionality. Each service receives only the data necessary for its specific purpose:

Stripe (Payments)

We use Stripe to process payments and manage subscriptions. When you purchase a license or subscribe to a plan, your payment information is handled directly by Stripe. Stripe's privacy policy is available at stripe.com/privacy.

WorkOS (Authentication)

The web app uses WorkOS for user authentication. WorkOS receives your email address and name during sign-up and login. WorkOS's privacy policy is available at workos.com/privacy.

Netlify (Deployment)

If you choose to deploy your project through Backdraft's Netlify integration, your project files are sent to Netlify at your explicit request. This is a user-initiated action — no data is sent to Netlify unless you actively choose to deploy. Netlify's privacy policy is available at netlify.com/privacy.

GitHub (Version Control)

If you choose to connect your GitHub account and push code through Backdraft, your project files are sent to GitHub at your explicit request. This is a user-initiated action. GitHub's privacy policy is available at docs.github.com.

LLM Providers (AI Features)

Backdraft supports multiple LLM providers for its AI editing and generation features:

You choose and configure your LLM provider. We recommend reviewing the privacy policy of any cloud-based LLM provider you choose to use.

Unsplash (Image Search)

Backdraft's image search feature queries the Unsplash API to find stock photos. Search queries are sent to Unsplash when you use this feature. Unsplash's privacy policy is available at unsplash.com/privacy.

Google Fonts API (Font Browsing)

The Font Library feature queries the Fontsource API and loads fonts from Google Fonts. Font browsing activity is subject to Google's privacy policy, available at policies.google.com/privacy.

4. データの保存とセキュリティ

Desktop App

The desktop app stores all data locally on your machine. This includes project files, AI chat history, application preferences, and cached data. Data is stored in the application data directory and in localStorage. No project data is transmitted to Backdraft servers.

Web App

The web app uses a server-side PostgreSQL database to store account information, license data, and subscription status. Project editing in the web app is performed client-side in the browser. HTTPS encryption is used for all communication between your browser and our servers.

Security Measures

We implement industry-standard security measures to protect your information, including:

No Sale of Data

We do not sell, rent, or trade your personal information to third parties. We do not share your data with third parties for their marketing purposes.

8. 本ポリシーの変更
