Privacy Policy

Last updated: November 2025

At OneLinerAI, your privacy is simple — we only collect what's necessary to make the product work and improve it.

1. Information We Collect

Free users

  • No personal account is required.
  • Text inputs.
    When you describe your product, that text is securely sent to OpenAI's API to generate your one-liner. We don't store or reuse the text.
  • Product analytics (PostHog) — we use PostHog to understand how people use OneLinerAI.
    We collect anonymous, aggregated data such as:
    • Pageviews and navigation events
    • Clicks and button interactions
    • Session duration and device type
    • Input length, word count, and response times
    This data never includes your text content or any personally identifying information. It's only used to improve performance and user experience.

Pro users

  • If you upgrade via Lemon Squeezy, we receive limited billing metadata (email, country, plan type, subscription status).
  • This data is stored securely in Supabase and used only to manage your Pro access.

Hosting logs (Vercel)

  • Vercel automatically collects minimal request logs (IP address, timestamp, path) for performance and security.
  • These logs are automatically rotated and deleted by Vercel.

2. How We Use the Data

  • We process your inputs only in real time to generate one-liners — they are not stored or reused.
  • Analytics help us understand product usage and performance in aggregate form only.
  • Billing metadata is used exclusively to manage Pro subscriptions and access.

3. Third-Party Services

4. Data Retention

  • Prompts and generated lines are never stored.
  • Analytics metadata is retained to improve the product but cannot identify individuals.
  • Billing data is kept as required for accounting and subscription management.
  • Access logs are automatically deleted by Vercel.

5. Security

All communication uses HTTPS and runs on trusted infrastructure (Vercel, Supabase, OpenAI, Lemon Squeezy).

We follow best practices for data protection and minimal data handling.

6. Your Choices

  • You can opt out of non-essential analytics via your browser's "Do Not Track" setting.
  • If you hold a Pro account and wish to delete your data, contact us at any time.

7. Changes

Any updates to data collection (for example, new analytics or account features) will be reflected here before taking effect.
