Kohii stores all your coffee data locally on your device. There is no account, login, or cloud sync, and your beans, brews, notes, and photos never leave your phone. The only things that ever leave your device are anonymous crash diagnostics, anonymous usage analytics and, in the free version, the advertising data described under Ads below — none of them includes anything you have typed or photographed.
Your bean bags, brew logs, ratings, and tasting notes are stored in a local SQLite database on your device. This data never leaves your phone unless you choose to export a backup file yourself.
If you add a photo to a bean or a brew, the app accesses your camera or photo library only at the moment you choose an image. Photos you select are copied into the app's local storage on your device and are never uploaded anywhere.
Kohii lets you export your coffee log to a backup file and restore it later. These backup files are created and stored only where you choose to save them on your device. We never receive, access, or transmit them.
Kohii uses Firebase Crashlytics to collect anonymous crash diagnostics (device model, OS version, and the technical state of the app at the moment of a crash). No personal information, coffee data, notes, or photos are ever transmitted. Crash reports exist solely so we can fix defects, and are covered under our legitimate interest in keeping the app working.
Kohii uses Google Analytics for Firebase to understand which features are used, so we can improve the app. It records anonymous, pseudonymous signals only — which screens you open, how often core features are used, whether Premium is active and when a subscription ends or resumes, the app version, your device model, and your coarse region (country level). It never records anything you type or photograph: not a coffee, a brew, a rating, a tasting note, a price, or a bag photo. Analytics is never used for advertising: advertising-personalisation signals are switched off. In Kohii 1.1 and earlier, in regions where consent is required (EEA, UK, Switzerland), analytics collection follows the choices you make in the ad consent form (Google Consent Mode).
From version 1.3.67, the free version shows a single banner advertisement. It appears at the foot of Today, the Shelf and the Journal, and on the coffee and brew pages you open from them — never while you brew, never in Settings, and never as a full-screen ad. Versions 1.2.62 to 1.3.66 show no advertisements and contain no advertising software. Versions 1.1 and earlier show a banner served by Google AdMob, which may collect device identifiers to serve ads, after asking for consent where the law requires it. Ads are served through Appodeal, an advertising mediation platform, and the ad networks it works with (including AppLovin, BidMachine, Digital Turbine, InMobi, ironSource, Liftoff, Mintegral, myTarget and Unity Ads). To choose, show and measure ads, they may collect your device's advertising identifier, your coarse location (derived from your IP address), your device type and operating system, and which ads you see and tap. None of your coffees, brews, notes or photos is ever shared with them. Before any ad is requested, you are asked for your consent choices where the law requires it (for example in the EEA, the UK and Switzerland). On iPhone and iPad, Apple's tracking prompt then asks whether ads may use your activity across other companies' apps and websites. If you decline either, ads are still shown, but they are not personalised. You can change your consent choices at any time from Settings → Manage Ad Consent, and your tracking choice in your device's Settings. Appodeal's own policy is at https://appodeal.com/privacy-policy. Kohii Premium — the one-time unlock or the monthly subscription — removes advertising entirely: the ad software is not started at all.
Kohii Premium — a one-time unlock or a monthly subscription — is processed by the Apple App Store (iOS) or Google Play (Android). We never see or store your payment details. The app asks your app store whether your purchase or subscription is active so it can unlock Premium. A subscription renews each month until you cancel it, which you do from your App Store or Google Play account settings; refunds are handled by the store.
All your data is yours. You can export it anytime from within the app, or delete it entirely by uninstalling the app. We have no central record of your data.
