Privacy

Last updated 24 August 2026

Cellar keeps a record of drinks you own. This page describes exactly what that involves — what is stored, who else processes it, and how to get rid of it.

What we store

• Your account. An email address and a password, handled by Supabase Auth. Optionally a display name.
• Your cellars. The drinks you add and everything you record about them — producer, vintage, style, quantity, price, purchase source, star rating and tasting notes — plus which cellar each belongs to and who you have shared it with.
• Photos. Images you capture or upload, and the cleaned-up versions generated from them.
• Assistant conversations. Chats with Rémy and Brew, so they can refer back to what you have discussed.

Who else processes it

• Supabase — database, authentication and file storage. Your cellar data lives here.
• Google Gemini — reads labels you photograph, produces the cleaned-up product images, and powers the assistants' voice and text conversations. Images and messages you send to an assistant are processed by Google to answer them.
• PostHog (EU region) — product analytics: which screens are used and which features are working. Events are tied to your account id, and your email and display name are attached so accounts can be told apart. No cellar contents are sent to PostHog.
• Vercel — serves this website and the app, and counts visits to them. Vercel's analytics is aggregate and cookieless: it records that a page was viewed, from roughly where and on what kind of device, and ties none of it to your account or to any identifier that follows you between visits. Pages that carry a share code or a bottle id are reported as the screen rather than the address, so no share link and no cellar contents reach it.

Sharing is something you choose

Cellars are private until you share them. When you invite someone as a viewer or an editor, they see that cellar's contents. When you create a public link to a cellar or a single bottle, anyone holding that link can view it without signing in — the link contains an unguessable code, and prices stay hidden unless you turn them on. Photos in shared cellars are served from a public storage bucket, so a photo's direct URL is viewable by anyone who has it. You can revoke a share at any time.

Deleting your data

You can delete your account from Account settings in the app. Deleting an account removes your profile and the cellars you own, along with their contents. Cellars owned by someone else that you were invited to are not affected.

Cookies

Cellar sets two small cookies on cellar.life, both purely functional — there are no advertising or tracking cookies, and nothing here follows you to other sites.

• One remembers whether you chose light or dark mode, so the app and this site agree.
• One records only that this browser has signed in, so this site can offer you a way back to your cellar instead of asking you to sign in again. It contains no name, no email and no sign-in token — just a marker — and it is removed when you sign out.

What we don't do

Cellar does not sell your data, does not run advertising, and does not share your cellar contents with anyone you have not shared them with yourself.
