Privacy Policy

Last updated: January 2025

1. Introduction

Kitha ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Chrome extension and web service for detecting AI-generated tweets.

2. Information We Collect

Account Information

When you create an account, we collect your email address for authentication via magic link login.

Tweet Content

When you use our extension, we analyze the text content of tweets visible on your screen to determine if they are AI-generated. We do not store the full text of tweets. We only cache detection results (AI probability scores) temporarily to improve performance.

Usage Data

We track the number of scans you perform daily for rate limiting purposes and to provide usage statistics in your dashboard.

Payment Information

If you subscribe to Pro, payment processing is handled by Stripe. We do not store your credit card details. We only receive confirmation of your subscription status from Stripe.

3. How We Use Your Information

  • To provide and maintain our AI detection service
  • To authenticate you and manage your account
  • To process subscription payments
  • To enforce usage limits for free accounts
  • To improve our AI detection algorithms
  • To respond to your feedback and support requests

4. Data Storage and Security

Your data is stored securely using industry-standard encryption. We use:

  • PostgreSQL database hosted on Supabase for user accounts and usage data
  • Redis for temporary caching of detection results (expires after 24 hours)
  • HTTPS encryption for all data transmission
  • Secure API keys for extension authentication

5. Data Sharing

We do not sell, trade, or rent your personal information to third parties. We may share data with:

  • Stripe: For payment processing (Pro subscriptions)
  • Resend: For sending magic link authentication emails
  • Infrastructure providers: Vercel, Railway, and Supabase for hosting services

6. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request deletion of your account and associated data
  • Export your usage data
  • Opt out of non-essential communications

To exercise these rights, contact us via DM on X (Twitter) at @OrdinaryWeb3Dev

7. Cookies and Local Storage

We use cookies for session management (keeping you logged in). The Chrome extension uses local storage to save your API key securely in your browser.

8. Children's Privacy

Kitha is not intended for users under 13 years of age. We do not knowingly collect personal information from children under 13.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
