Crock · Last updated: October 8, 2026
Crock is made by Karol Jaworski ("we"). This policy explains what leaves your device when you use Crock, who receives it and why. Questions: karoljaworsky@gmail.com.
What you enter in Crock is stored on your device. If iCloud is turned on for the app, it is also synced to your private iCloud account, which Apple operates and we cannot access.
Purchases in Crock are processed by Apple. We use RevenueCat to keep track of your subscription status; RevenueCat receives the purchase records Apple provides and an app user ID, never your name or the content you store in the app. RevenueCat Privacy Policy.
If you ask Apple for a refund of a purchase made in Crock, Apple may ask us for information about that purchase. By making a purchase, you consent to us (through RevenueCat) sharing the following with Apple for that request: how long you have had the app, how much of the purchased period has been used, whether the purchase was delivered, and the total amount you have spent and been refunded in Crock. We may also tell Apple whether we think the refund should be granted. Apple makes the final decision. We never share the content you store in the app.
Crock's optional photo check gives you a second opinion on what is growing on a ferment. It only runs when you pick a photo and tap "Check this photo", and Crock asks for your permission before the first one. When you use it, the photo, together with the batch's type, day number, stage, room temperature and any issues you flagged, is sent through our server (hosted by Cloudflare) to xAI, whose Grok model analyses it and returns a short description. Our server forwards the request and does not keep a copy of the photo or the result. xAI processes it under its own terms. Nothing that identifies you, such as your name or Apple ID, is sent with it. The result is saved only on your device, and only if you choose "Save to the journal". xAI Privacy Policy.
Crock contains no analytics or advertising SDKs. We do not track you across apps or websites, and we do not sell your data or share it for advertising.
Crock is not directed at children under 13.
You can delete the data on your device by deleting the app and data synced to iCloud from iOS Settings → your name → iCloud. If you are in the EU, UK or a similar jurisdiction, you have the right to access, correct, delete and move your data, to object to its processing, and to complain to your data protection authority. To exercise any of these rights, email karoljaworsky@gmail.com.
We update this page whenever what Crock sends changes; the date at the top shows the current version.
