Privacy Policy

This policy explains what we collect when you use SchemaLab, why we collect it, who processes it on our behalf, and the choices you have. We collect the minimum needed to run the practice and performance loops.

Account information: your email and authentication details, and any profile fields you provide (such as experience level).

Content you create: the data models, submissions, challenge progress, and interview transcripts you generate while using the Service.

Usage data: product analytics events (pages viewed, features used) collected to improve the Service.

Payment information: if you subscribe, billing is handled by Stripe. We do not store full card numbers; we receive limited subscription and status information from Stripe.

To provide and maintain the Service, run deterministic and AI-assisted feedback, manage subscriptions, communicate with you about your account, secure the platform, and improve content and features.

We share data with processors that help us operate the Service:

Supabase — database, authentication, and storage.
Stripe — payment processing and subscription billing.
PostHog — product analytics.
Anthropic — AI processing for tutoring, design feedback, and mock-interview evaluation.
Vercel and Railway — application and API hosting.

Each processes data only to provide their service to us, under their own terms. We do not sell your personal information.

When you use AI features, the relevant context (such as your current model and the challenge) is sent to our AI provider to generate feedback. We instruct providers not to use your content to train their models, consistent with their commercial terms. AI feedback is assistive and is bounded by our deterministic checks.

We use cookies and similar technologies for authentication and to collect aggregate product-analytics events via PostHog. You can control cookies through your browser settings; some features require them to function.

We retain your account and content for as long as your account is active. You can delete your account and associated content at any time by contacting us at support@schemalab.ai; we will delete or anonymize your data within a reasonable period, except where retention is required by law (for example, payment records).

Depending on your location, you may have rights to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise these rights, contact us at the email above.

We use industry-standard measures including encrypted transport, authentication, and tenant isolation so users can only access their own data. No method of transmission or storage is perfectly secure.

The Service is not directed to children under 16, and we do not knowingly collect their personal information.

We may update this policy from time to time. Material changes will be posted here with an updated date.
