1. Introduction

Welcome to HumanTone ("we," "our," or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and services.

By using HumanTone, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this Privacy Policy, please do not access or use our services.

2. Information We Collect

Information You Provide

  • Account Information: When you create an account, we collect your name, email address, and authentication credentials (password or Google OAuth token).
  • Payment Information: When you subscribe to a paid plan, payment is processed by Stripe. We do not store your credit card details directly — Stripe handles all payment data securely.
  • Content You Submit: Text you input for humanization, summarization, or note generation is processed in memory and is not permanently stored. Generation history (prompts and responses) is stored in your account for your convenience.
  • Communications: If you contact us via our support form, we collect the information you provide in those communications.

Information Collected Automatically

  • Usage Data: We collect information about how you interact with our services, including pages visited, features used, and generation counts.
  • Device Information: We may collect information about your device, including browser type, operating system, and screen resolution.

We use the information we collect to:

  • Provide, maintain, and improve our services
  • Process your transactions and manage your subscription
  • Send you important service notifications (billing, account changes)
  • Respond to your inquiries and support requests
  • Monitor and analyze usage patterns to improve user experience
  • Detect, prevent, and address technical issues or abuse

4. Data Storage and Security

Your data is stored securely using Supabase (PostgreSQL) with Row-Level Security (RLS) policies enabled on all tables. We implement industry-standard security measures including encrypted connections (TLS), secure authentication, and access controls.

Text submitted for processing (humanization, summarization, note generation) is processed in memory and is not stored on disk or used for AI model training. Only the generation history (your prompts and responses) is stored in your account database for your reference.

We use the following third-party services:

  • Supabase: Authentication and database hosting

  • Vercel: Web hosting and analytics
  • PostHog: Product analytics and user experience improvement
  • Sentry: Error tracking and performance monitoring
  • Resend: Transactional email delivery

  • Correction: Request that we correct any inaccurate personal data
  • Deletion: Request that we delete your account and associated data
  • Export: Request a portable copy of your data
  • Opt-out: Opt out of non-essential analytics and tracking

7. Data Retention

We retain your account information and generation history for as long as your account is active. If you delete your account, we will remove your personal data within 30 days, except where we are required to retain it for legal or compliance purposes.
