CoffeeComp · your private coffee companion
Privacy policy
Effective 28 October 2026. Applies to CoffeeComp for iOS, version 1.1 and later.
CoffeeComp does not collect any data. No account, no sign-up, no analytics, no advertising, no tracking, and no servers of ours. Your taste profile, coffee log, saved beans and chat history are stored on your iPhone, and the AI that makes recommendations runs on your iPhone. The only network requests the app makes are to coffee roasters' own websites, so it can show you coffees that are really in stock, and those requests contain nothing about you.
What the app stores on your device
| Data | Why |
|---|---|
| Taste profile: survey answers, taste readings, preferred brewing methods, profile name | To match coffees to your palate |
| Coffee log: coffee name, roaster, roast, method, rating, notes, mood, date | Your journal; it also feeds recommendations |
| Saved beans and your Roasters to shop list | So Discover and the Expert know what you care about |
| Expert chat history | So the conversation is there when you come back |
| A random profile identifier | To tell your profile apart from a previous one on the same device. It is not linked to you, your Apple ID, or anything outside the app |
| A small cache of roaster shop results | So Discover loads quickly without re-checking every roaster each time |
The database is protected with iOS data protection, so it is encrypted whenever the device is locked. Because it is the only copy of your log, it is included in your normal iPhone backup (iCloud Backup or a computer backup). That backup is handled entirely by Apple under Apple's privacy policy.
Deleting your data: swipe a cup to delete it, remove saved beans and roasters from your profile, or delete the app, which removes everything it stored.
AI features
Recommendations and the Coffee Expert use Apple Intelligence, which runs the language model on your iPhone. Your profile, coffee log and chat messages are given to that model on the device. They are not sent to any third-party AI service, and we never see them.
When a long conversation with the Coffee Expert no longer fits the on-device model, that conversation continues on Apple Private Cloud Compute. Apple processes those requests on its servers in a way designed so that the data is not stored and is not accessible to Apple or to us; the request is tied to your Apple Account and counts toward Apple's daily limit for Apple Intelligence cloud requests. The badge above a reply says whether it came from your iPhone or from Private Cloud Compute, and tapping it explains both. Discover and the first part of every conversation stay on the device.
If Apple Intelligence is unavailable on your device, the app falls back to built-in matching rules with no network use.
Network requests
CoffeeComp has no servers. The app only connects to:
- Coffee roasters' own websites
- To show you coffees that are actually in stock, Discover loads the public product list from the websites of roasters you have logged, added, or that are on the app's featured list. These requests go straight from your iPhone to the roaster's site over HTTPS. They include no personal information and no identifier from the app; like any web request, the roaster's server sees your device's IP address. The app never submits anything to those sites.
- Public web pages the Coffee Expert looks up
- When you ask about a roaster or café, the Expert may read a public page to answer. Same rules: HTTPS only, straight from your device, nothing about you in the request, and the page is used only to answer your question.
- The roaster's shop, when you tap Shop
- Shop links open the roaster's website in an in-app Safari view. From that point you are browsing the roaster's site under that roaster's privacy policy. CoffeeComp has no visibility into what you do there and receives nothing back.
The app never contacts advertising, analytics or social networks.
What we don't do
- We don't collect, store, sell or share personal data.
- We don't use third-party SDKs, analytics, crash reporting or advertising.
- We don't track you across apps or websites.
- We don't require or offer an account.
- We don't send push notifications.
Children
CoffeeComp is rated 4+ and does not knowingly collect any information from anyone, including children.
Your rights
Because we hold no data about you, there is nothing for us to access, correct, export or erase on your behalf; all of it is on your device and under your control. If you have questions about this policy you can still reach us below.
Changes
If the app's behaviour changes in a way that affects your privacy, for example optional iCloud sync of your own data between your devices, the new version will be posted at this address with a new effective date, and the app's release notes will say so.
