Privacy Policy

Effective Date: November 1, 2025

Our Privacy Commitment

HashtagCraft is built with privacy-first principles. We believe your content and creative work should remain yours, stored locally on your device, not on our servers.

What Data We Collect

Data Stored Locally (In Your Browser Only)

The following data is stored exclusively in your browser using IndexedDB and never leaves your device:

  • Generation History: Your caption generations, including input descriptions, tone selections, and generated results
  • Favorites: Captions and hashtags you've marked as favorites
  • Preferences: Your dark mode setting and other UI preferences

Important: This data is stored locally on your device. If you clear your browser data or use a different device, this information will not be available.

Data Sent to Third-Party Services

When you generate captions, we send your input to AI service providers:

  • What We Send: Your post description, selected tone, length preference, and emoji style
  • AI Provider: Anthropic (Claude API)
  • Purpose: To generate AI-powered caption suggestions
  • Retention: AI providers may temporarily process this data according to their own privacy policies. We recommend reviewing Anthropic's Privacy Policy.

We do NOT send:

  • Your name or personal identification
  • Your IP address (beyond what's required for API communication)
  • Your generation history
  • Your favorites
  • Any identifying information about you

Your Rights and Control

You have complete control over your data:
