Your wine journal stays on your device.

The short version

There's no account, and nothing about your journal is sold or shared. Your bottles, ratings, notes, and wine history stay on your device. Two things go to OpenAI: a new bottle's label photo, so its details can be filled in, and an anonymous summary of your taste, so Corklist can suggest what to try.

What Corklist stores

The wines you log, including photos, notes, and ratings, are saved locally on your device. That's used only to build your journal and your palate, and it never leaves your device.

Camera and photo library

Corklist asks for the camera or your photo library so you can attach a photo of a label. The photo itself is saved on your device with the bottle.

Reading labels

When you add a photo to a new bottle, a smaller copy of it is sent through a Corklist server to OpenAI, which reads the label and suggests the producer, wine, vintage, grape, region, country, and style. To identify the wine accurately, OpenAI may search the web using the text it reads on the label; the photo itself is not published or shared. Only the photo is sent: not your other bottles, ratings, or notes, and no name or account.

The Corklist server doesn't keep the photo. To limit how often labels can be read, it keeps a daily count tied to a random ID for your copy of the app and to your network address, and those counts expire after two days. OpenAI handles the photo under its API terms; see OpenAI's privacy policy.

Without a connection, or if that service isn't available, the label is read on your device with Apple's built-in text recognition instead, and nothing is sent.

Your palate

What Corklist learns about your taste is worked out on your device, from the bottles you've rated and Corklist's built-in wine reference data. Your ratings, notes, and the bottles themselves are never sent anywhere or shared with anyone, including me.

Suggestions

To suggest what to try, Corklist sends a summary of your palate through a Corklist server to OpenAI. The summary contains only names from Corklist's reference data (grapes, places, winemaking methods, and tasting words) with a rough sense of whether you lean toward or away from each, plus a broad range for how many bottles you've rated. It never includes your bottles, producers, wine names, vintages, prices, dates, ratings, or notes. The server rejects anything else, doesn't keep the request, and counts requests per day the same way as for label reading.

Exporting your journal

If you export your journal as a CSV file, you decide where it goes. I never see a copy of it unless you choose to send me one yourself, for example if you're emailing about a bug.

Data collection and tracking

Corklist doesn't use advertising trackers and doesn't track you across other apps or websites. It doesn't collect analytics from your journal either.

If you've opted in to sharing diagnostics with app developers in your Apple settings, Apple may pass along crash reports. I only use those to fix bugs.

Website hosting

This site, including this page, the support page, and the Corklist server, is hosted by a third-party provider that logs standard technical information to keep the site running and secure. I don't use those logs to identify you or build a profile of you.

Children's privacy

Corklist is a journal for wine and is meant for adults of legal drinking age. It isn't directed at children, and I don't knowingly collect personal information from children.

Deleting your data

Since everything lives on your device, you're in control. Delete individual wines in the app, or delete the app itself to remove everything at once.
