Privacy Policy

At MyD1 LLC, we believe your database schema and queries are your business, not ours. Our privacy philosophy is simple: if we don't need it, we don't collect it.

1. Data Collection & Usage

• Database Credentials — Your database passwords and API tokens are stored locally on your Mac using the secure macOS Keychain. We never see, store, or transmit these to our servers.
• Database Content — MyD1 is a local client. Your data travels directly from your Mac to your database provider (Cloudflare, AWS, etc.). It never passes through MyD1 servers.
• AI Features (Pro) — If you use the AI Assistant, your schema and prompts are sent directly to the provider (OpenAI, Anthropic, or xAI) using your own API key. We do not act as a middleman for this data.
• Account Data — When you create an account, we collect your email address, name (optional), and an encrypted password. When you purchase Pro, Stripe processes your payment — we never see or store your card details.
• Device Activations — When you activate a license, we store a hashed machine identifier and an optional device name.

2. What We Don't Collect

The MyD1 macOS application does not include any telemetry, analytics, or tracking. No personal files, database contents, or queries are ever transmitted from the app to our servers. We do not use cookies for advertising or third-party tracking.

3. Download Analytics

When you download the app, we log a hashed IP address, country code (via Cloudflare headers), referrer URL, and user agent string. This data is used solely to understand download trends and is never sold or shared with third parties.

4. Marketing

We hate spam. We will never sell your data to third parties or governments. We use your email solely for license management and critical app updates.

5. How Data Is Stored

All data is stored on Cloudflare D1 (SQLite), encrypted at rest by Cloudflare's infrastructure. Our application runs on Cloudflare Workers within Cloudflare's global network.

6. Third-Party Services

• Stripe — Payment processing. Subject to Stripe's Privacy Policy.
• Resend — Transactional email delivery. Subject to Resend's Privacy Policy.
• Cloudflare — Hosting, CDN, and database. Subject to Cloudflare's Privacy Policy.

7. Cookies

We use a single session cookie to keep you signed in and essential cookies for Stripe payment processing. No advertising cookies, no tracking pixels, no third-party cookies.

8. Data Retention

Account data is retained as long as your account exists. Download analytics are retained for 12 months. You can delete your account at any time from your account settings, which removes all associated data.

9. Your Rights

You have total control over your data. At any time, you can contact us at Hello@MyD1.com to:

• Request a summary of the data we have associated with your license (typically just your email and purchase date).
• Request the permanent deletion of your customer record.

You can also manage your data directly from your account dashboard.

10. Changes

We may update this policy from time to time. Significant changes will be communicated via email to registered users.
