Your taste, organized.

Privacy Policy

Last updated April 19, 2026

Catalog is designed with your privacy in mind. This policy explains what data the app handles and how it's handled.

Data stored on your device

Nearly everything you do in Catalog stays on your device. This includes:

• Your shelves, catalog items, and reading status
• Onboarding progress and app preferences
• Cached cover art and item metadata

This data never leaves your device unless you explicitly enable cloud sync.

AI recommendations (Syllabus)

When you use the Syllabus feature, Catalog sends the title, creator, and media type of the item you selected to Anthropic's API to generate recommendations. No personal data — no name, email, or identifiers — is included in that request.

Anthropic's processing of this data is governed by their privacy policy.

Optional cloud sync

If you sign in to sync across devices, Catalog uses Supabase to store your email address, authentication tokens, and a synced copy of your catalog data. You can delete your account and all associated data at any time from the in-app settings.

What we don't do

• No analytics or behavioral tracking
• No advertising or third-party ad networks
• No selling, sharing, or licensing of your data
• No cookies (Catalog is a native iOS app)

Terms of Use

Last updated April 19, 2026

By using Catalog, you agree to these simple terms.

As-is

Catalog is provided as-is, without warranty of any kind. We do our best to make the app reliable and useful, but we can't guarantee it will always be error-free or available.

AI recommendations

The Syllabus feature generates recommendations using a third-party AI service (Anthropic Claude). These recommendations are suggestions only — they may be inaccurate, outdated, or not match your taste. Treat them as a starting point for your own discovery, not authoritative advice.

Your data, your responsibility

Your catalog lives on your device (and optionally syncs to the cloud if you enable that). You're responsible for backing up anything you want to keep. We recommend enabling cloud sync if your catalog matters to you.

Changes

We may update these terms as Catalog evolves. Meaningful changes will be surfaced in the app.

Support

We'd love to hear from you

Catalog is built by one person. Every email is read by the person who made the app.

When reporting a bug, it helps to include:

• Your iOS version and device model
• What you were doing when the issue happened
• A screenshot, if relevant
