Privacy Policy

Overview

NeuralDiff ("we", "us", "our") is committed to protecting your privacy. This policy explains how we collect, use, and safeguard your information when you use our website, SDK, API, and related services (collectively, the "Service").

Information We Collect

Account Information

When you create an account, we collect your email address, name, and authentication credentials. If you sign up through a third-party provider (e.g., GitHub), we receive your profile information from that provider.

Usage Data

We collect anonymous usage metrics including page views, feature usage, and performance data to improve the Service. This data is aggregated and cannot be used to identify individual users.

Screenshots and Analysis Data

When using cloud analysis features, screenshots are transmitted to our servers for processing. Screenshots are processed in memory and are not permanently stored unless you explicitly save them to your project history. Local analysis (via the daemon) never sends data to our servers.

Payment Information

Payment processing is handled by Stripe. We do not store credit card numbers or sensitive financial data on our servers. Stripe's privacy policy governs the handling of your payment information.

How We Use Your Information

• To provide and maintain the Service
• To process payments and manage subscriptions
• To send transactional emails (account verification, password resets, billing receipts)
• To improve the Service based on aggregated usage patterns
• To respond to support requests

Data Sharing

We do not sell your personal information. We share data only with:

• Service providers — Stripe (payments), Supabase (authentication and database), Vercel (hosting)
• Legal requirements — When required by law or to protect our rights

Local-First Architecture

NeuralDiff is designed with a local-first architecture. The SDK and daemon run entirely on your machine. Screenshots, comparisons, and analysis results stay local unless you explicitly use cloud features. You control what data leaves your environment.

Data Retention

Account data is retained while your account is active. Cloud analysis history is retained according to your plan (7 days for free, 90 days for Team, 1 year for Business). You can delete your account and associated data at any time by contacting us.

Security

We implement industry-standard security measures including encryption in transit (TLS), encryption at rest, and row-level security policies on all database tables. Access to production systems is restricted and audited.

Your Rights

You have the right to:

• Access your personal data
• Correct inaccurate data
• Delete your account and data
• Export your data
• Opt out of non-essential communications

Cookies

We use essential cookies for authentication and session management. We do not use third-party tracking cookies. Analytics data is collected server-side without cookies.

Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes via email or a notice on the Service.
