Privacy Policy

Last updated: February 2026

1. Data We Don't Collect

We do not collect, store, or transmit any personal information you enter into the signature builder, including your name, job title, company name, email address, phone number, website URL, or social media links. All processing happens entirely within your web browser using JavaScript.

2. Local Storage

SigBlock uses your browser's localStorage to save:

• Your signature draft (so you can return to it later)
• License/subscription status
• Daily usage count (for free tier limits)
• Cookie consent preference

This data never leaves your device and can be cleared at any time through your browser settings.

3. Cookies and Advertising

Free-tier users may see ads from Google AdSense. AdSense uses cookies for ad personalization. You can accept or reject ad cookies via our cookie consent banner. Pro users see no ads.

We implement Google Consent Mode v2 to respect your cookie preferences.

4. Authentication

If you sign in to access Pro features, authentication is handled by our shared auth service (auth.cashewcrate.com). This service stores your email address and subscription status. It does not have access to your signature content.

5. Third-Party Services

• Google AdSense: Ad serving for free-tier users (with consent)
• Polar: Payment processing for Pro subscriptions
• Cloudflare: Hosting and CDN

6. Your Rights

Since we don't store your signature data, there is nothing to delete. You can clear localStorage at any time. For auth-related data, contact us to request deletion.

7. Contact
