Privacy policy
Effective October 3, 2026
Cellar (c3llar.cloud) is a personal coffee log: one person's notes on the coffees they buy and brew, shared publicly to read. This page says what information the site handles and why. It is run by the owner of c3llar.cloud, who can be reached at kwanzoop@gmail.com.
If you only read the site
You can read the Inventory, Log and Recipes without an account. Cellar does not use analytics, advertising, tracking pixels or third-party cookies, and it does not build a profile of you.
- Server logs. The site is hosted on Google Firebase Hosting. Like any web host, Google records basic request data (such as your IP address, browser and the pages requested) to deliver and protect the service. See Google's privacy policy.
- Your browser's own storage. The site keeps a few settings on your device, such as light or dark mode and other display choices, and a cache of the pages' data so they load quickly. These stay in your browser and are never sent to anyone. You can clear them at any time in your browser's settings.
If you sign in
Signing in is meant for the site's owner, who edits the log. If you choose "Sign in with Google" anyway, Google shares your Google account's basic profile with the site (your email address, name and profile picture), and Google Firebase Authentication keeps a record of your account (that information, a user ID, and when you signed in). Accounts other than the owner's can only read, the same as without signing in; nothing else is stored about them. To have your sign-in record deleted, email the address above.
What the log contains
The coffee log itself (coffees, brews, recipes, ratings and notes) is the owner's own content, stored in Google Firebase (Cloud Firestore and the Realtime Database). Part of it is public by design: the coffees on the shelf, the brew log and the recipes. Private parts (such as prices, purchase notes and settings) are shown only to the owner.
Coffee lookups
When the owner asks Cellar to look a coffee up online, the coffee's name, roaster, the details already known and the owner's photo of the bag are sent to Anthropic's Claude (through a small computer the owner runs at home) so it can search the web for the rest. No information about visitors is involved. See Anthropic's privacy policy.
Sharing and selling
Cellar does not sell or rent personal information, and does not share it except with the services named above, which run the site.
Children
Cellar is not directed to children under 13 and does not knowingly collect their information.
Your choices
You can read the site without signing in. If you signed in and want your record removed, or have any question about this policy, email kwanzoop@gmail.com. Depending on where you live, you may have further rights (for example, to access or delete your information); the same address handles those requests.
Changes
If this policy changes, the new version will be posted here with a new effective date.
