Privacy Policy

Last updated: April 10, 2026

1. Overview

Silkwind ("we", "our", or "us") is a privacy-first email client. This Privacy Policy explains how we handle information when you use Silkwind and when you sign in with Google.

2. Information We Collect

When you authenticate with Google OAuth2, we request access only to the following scopes:

Your email address and basic profile (name, profile picture) — used solely to identify your account within the application.
Gmail read/send access — used only to fetch and send your emails inside the Silkwind client.

We do not collect, store, or transmit your email data to any server we operate. All email data is processed locally on your device.

3. How We Use Your Information

To authenticate your identity and link your email account to Silkwind.
To display your emails within the application.
To send emails on your behalf when you explicitly compose and send a message.

We do not use your information for advertising, analytics, or any purpose beyond operating the email client.

4. Data Storage

Silkwind stores email data locally on your device only. OAuth2 tokens are stored securely in your operating system's credential store (Keychain on macOS, Credential Manager on Windows, libsecret on Linux). We never transmit your OAuth2 tokens or email content to our servers.

5. Data Sharing

We do not sell, trade, or share your personal information with third parties. The only third-party service involved is Google, whose use of your data is governed by Google's Privacy Policy.

6. Data Retention

You can revoke Silkwind's access to your Google account at any time via Google Account permissions. Locally cached data can be deleted by removing the application and its data directory.

7. Security

We take reasonable precautions to protect your data. All communication with Google's APIs uses TLS. OAuth2 tokens are never stored in plaintext.

8. Children's Privacy

Silkwind is not directed at children under the age of 13. We do not knowingly collect personal information from children.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version on this page with a revised date.
