Your cups stay yours
Privacy Policy
Good Coffee
Effective date: November 2, 2026
Hien Nguyen (“we”) develops Good Coffee, an iPhone app that helps you log coffee and learn what you like. This policy explains what the app does with your information and covers the app and these support pages.
In short: Good Coffee has no account, no advertising, no analytics or crash-reporting SDK and no tracking. Your cups, photos and taste profile are kept on your iPhone. We do not receive them.
1. What stays on your iPhone
Everything you put into Good Coffee is stored in the app on your device:
- the cups you log: the drink, your rating, tasting notes, how it was served (iced or hot, sugar, milk), the moment, the place name you type, the time and a caffeine estimate;
- photos you add to a cup, kept as a cut-out “sticker” of the cup;
- how you felt after a cup (“alert, normal or jittery”) if you answer a check-in;
- your bean shelf, including a small copy of a coffee bag photo when you add that bag;
- your answers to the taste quiz, your usual drinks and the taste profile the app calculates from your ratings;
- settings such as your bedtime, caffeine sensitivity and check-in preferences.
Good Coffee has no cloud sync of its own and no server that receives this data. If your iPhone is backed up to iCloud or a computer, the backup may include the app’s data according to your device settings.
2. Camera and photos
The app uses the camera only while you scan a menu, a coffee bag or a cup. You can also choose a photo with the system photo picker; the app then receives only the photo you pick, not your photo library.
Reading the text on a menu or bag, cutting a cup out of its photo and guessing the drink are done on your iPhone with Apple’s on-device Vision framework. Photos are not uploaded. A menu photo is used only while its results are open. A bag photo is kept (as a small copy) only if you add the bag to your shelf, and a cup photo only if you save it with the cup.
3. Suggestions and your region
To suggest drinks you can actually order, the app reads your iPhone’s region setting (for example Vietnam or the United States). This setting is used on your device only. The app does not ask for your location.
4. Notifications and the widget
If you turn on after-cup check-ins, the app schedules local notifications on your iPhone. They are not sent through our servers or any notification service, and you can turn them off in the app or in iOS Settings.
The home screen widget shows today’s suggestion from a small summary that the app writes on your device for the widget to read.
5. Export and deletion
Settings → Your data lets you export your cups, check-ins, bean shelf and quiz answers as CSV and JSON files. The files go only where you choose to share or save them.
Settings → Your data → Delete all my data removes every cup, photo, check-in, bag, place and your taste profile from the app and cancels scheduled check-ins. Deleting the app also deletes its data from your iPhone. Data already in your device backups or in files you exported is not affected.
6. GoodCoffee Pro purchases
GoodCoffee Pro is an optional subscription sold through the App Store. Apple processes the payment; we do not receive your payment-card details or Apple Account information. The app checks Apple-signed transactions on your device to unlock Pro. Apple provides us with sales and subscription reports that do not identify you. You manage or cancel the subscription in your Apple Account settings. Apple handles purchases under the Apple Privacy Policy.
7. Analytics and crash reports
Good Coffee does not include any analytics, advertising or crash-reporting SDK. If you choose to share analytics with app developers in your iPhone’s settings, Apple may provide us with crash reports and aggregated usage information under the Apple Privacy Policy.
8. Support and this website
If you email us, we receive your email address, your message and anything you attach, and use them to answer and fix the issue. Please do not send passwords or payment details. These pages are hosted through Cloudflare, which processes request information such as IP address and browser details to deliver and protect the website. The Good Coffee pages do not include advertising or analytics scripts. See Cloudflare’s Privacy Policy.
Support emails are kept as long as needed to resolve the request and meet legal obligations.
9. Children
Good Coffee is a general-audience app and is not directed at children under 13. The app does not collect personal information from anyone, including children. Parents can manage purchases (for example with Ask to Buy) with Apple’s family controls.
10. Your choices and requests
Because your data stays on your iPhone, you can view, change, export or delete it in the app at any time. Depending on where you live, you may have rights to access, correct or delete personal information; for anything you sent us by email, contact bananateamios@gmail.com. You can also contact your local data protection authority.
11. Changes and contact
If the app ever starts handling data differently (for example an optional iCloud sync, which would use your own iCloud account), we will update this policy before that feature ships. The current version and its effective date are on this page. For privacy or support questions, contact Hien Nguyen at bananateamios@gmail.com.
