Privacy Policy

Last updated: August 17, 2026

This Privacy Policy explains what data API Espresso collects and how it's used.

1. What We Collect

• Account/billing data: your email and payment details, collected and processed by Lemon Squeezy (our merchant of record) — we do not see or store your full card details.
• API usage data: for each API request, we log the endpoint called, status code, response time, and (for the image comparison API specifically) the hostname only of any image URLs submitted — never the full URL, since URLs can contain sensitive query parameters. We do not store the images themselves.
• API key: stored only as a one-way cryptographic hash. We cannot see or recover your actual key.

2. How We Use It

• To operate the Service (authenticate requests, enforce quotas/rate limits, bill correctly)
• To troubleshoot issues and monitor abuse
• To communicate service-related notices (e.g. planned downtime, policy changes) to your billing email

3. Third Parties

• Lemon Squeezy — payment processing, billing, tax handling

We do not sell your data to third parties.

4. Data Retention

Usage logs are retained for 90 days for troubleshooting and abuse monitoring, then deleted. Billing records are retained as required by Lemon Squeezy/applicable tax law.

5. Your Rights

You may request a copy of the data we hold about you, or request deletion of your account data, by contacting support@apiespresso.com.
