Privacy Policy

Last updated: July 2, 2026

Caveau (“the app”, “we”) is a wine cellar management app. This policy explains what data the app handles and how. The short version: your cellar is yours, we don't sell data, and we collect the minimum needed to run the app.

What we collect

• Account data. On first launch you get an anonymous guest account. If you sign in (email, Apple, or Google), we store your email address and name so your cellar can sync across devices.
• Cellar data. The bottles, tasting notes, drinking logs, and audit records you create. Stored in our database (Supabase, hosted in the United States) and visible only to you.
• Label photos. When you scan a wine label, the photo is sent to Anthropic's Claude API to read the label text, then discarded. Photos are not stored on our servers and are not used to train AI models.

What we don't do

• We do not sell or share your personal data with advertisers or data brokers.
• We do not show ads or use third-party ad tracking.
• We do not use your data to train AI models.

Service providers

We use Supabase (database and authentication), Anthropic (label reading, drinking-window and pairing suggestions), Apple (subscriptions and sign-in), and Expo (app builds and delivery). Each receives only what it needs to provide its service.

Notifications

Drinking-window alerts are optional, scheduled on your device, and can be turned off any time in Settings.

Deleting your data

Settings → Delete my account permanently erases your account and every bottle, note, and log attached to it. This is immediate and cannot be undone.
