Privacy Policy
Last updated: October 31, 2025
Introduction
SignatureAI is committed to protecting your privacy. This Privacy Policy explains how we handle your data when you use our email signature generator tool. The most important thing to know: we don't collect, store, or transmit your personal information to our servers.
Local Data Storage
SignatureAI operates entirely in your web browser using local storage technologies:
- IndexedDB: Your signature data (name, job title, contact information, design choices) is stored locally in your browser's IndexedDB database.
 - Your Device Only: This data never leaves your device and is not transmitted to our servers.
 - Your Control: You can view, edit, or delete your saved signatures at any time through the History page.
 - Browser Clearing: Clearing your browser data will delete all saved signatures permanently.
 
AI Suggestions
When you request AI-powered design suggestions:
- We send your job title and optional company/industry information to our AI service provider
 - This data is used only to generate personalized suggestions and is not stored permanently
 - The AI service provider processes requests in accordance with their privacy policy
 - You can choose not to use AI suggestions and build your signature manually
 
Analytics & Cookies
We may use basic analytics to understand how visitors use our website:
- Anonymous usage statistics (page views, session duration)
 - No personally identifiable information is collected
 - You can block analytics using browser extensions or privacy settings
 
No User Accounts
SignatureAI does not require user accounts, registration, or login. You can use all features without providing any personal information beyond what you choose to include in your email signature design.
Share URLs
When you use the "Share Configuration" feature, your signature data is encoded in the URL. This means anyone with the share link can view the signature configuration you created. Only share these links with people you trust, and be mindful of including sensitive information in shared signatures.
Third-Party Services
SignatureAI may use third-party services:
- AI Gateway: For AI-powered suggestions (see AI Suggestions section)
 - CDN & Hosting: For fast and reliable website delivery
 - Font Providers: For web fonts (Google Fonts, etc.)
 
These services may collect basic technical information (IP address, user agent) in accordance with their own privacy policies.
Your Rights
Since all your data is stored locally in your browser:
- Access: You can view all your saved signatures in the History page
 - Deletion: You can delete individual signatures or clear all data
 - Export: You can export your signatures as HTML, PNG, or PDF
 - Control: You have complete control over your data at all times

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
