LifeLogix ("the app", "we") helps you track meals, water intake, activity and body metrics. This policy explains what data the app handles, where it goes, and the choices you have. Short version: your meal photos and Apple Health data never leave your device except as stated below, and you can delete your account and all data at any time inside the app.
| Data | Purpose | Where it is stored |
|---|---|---|
| Email address, name | Creating and signing in to your account (email, Sign in with Apple, or Google) | Firebase Authentication & Cloud Firestore (Google) |
| Profile & goals (age, gender, height, weight, activity level, dietary preference, daily calorie/step/water goals) | Calculating and tracking your personal goals | Cloud Firestore |
| Logged meals (dish name, calories, time, notes), water intake, body measurements (weight, waist, hip) | The core tracking features of the app | Cloud Firestore |
| Saved favourite recipes (title, image link, source link) | Your favourites list | Cloud Firestore |
| Language and unit preferences | Displaying the app the way you chose | On device + your profile |
| Subscription status (Prime) | Unlocking Prime features; purchases are processed entirely by Apple — we never see your payment details | Apple + a yes/no flag in Firestore |
| Crash reports & basic diagnostics | Fixing bugs (Firebase Crashlytics) | |
| Push notification token | Delivering reminders and service messages (Firebase Cloud Messaging) |
Photos you take or pick are stored locally on your device only. When you use AI analysis, the photo is transmitted securely to Google's Gemini AI service solely to estimate the dish and calories, and the result is returned to your device. We do not store your photos on our servers, and photos are not used to identify you.
With your permission, the app reads your step count and walking distance from Apple Health to display your daily activity. This data is read on your device, is never uploaded to our servers, is never shared with third parties, and is never used for advertising or marketing. You can revoke access at any time in iOS Settings → Health.
Free accounts may see rewarded ads served by Google AdMob (an optional "watch an ad for an extra scan" offer). If you allow tracking via Apple's App Tracking Transparency prompt, AdMob may use your device's advertising identifier to show more relevant ads. If you decline, you will see non-personalised ads and the app works exactly the same. In the EEA/UK, a consent form (Google UMP) is shown as required by law. Prime subscribers see no ads, and the advertising SDK is not even initialised for them. Health data is never shared with advertisers. See Google's advertising policy.
The Explore tab displays public recipes fetched from Cookpad. Requests go directly from your device; we do not attach your identity to these requests beyond standard network information.
The app relies on: Google Firebase (authentication, database, crash reporting, remote configuration, push notifications, app integrity checks — privacy), Google AI (Gemini) for meal photo analysis, Google AdMob for ads on free accounts, and Apple for sign-in, subscriptions and Apple Health. Each processes data under its own privacy policy.
Your data is kept while your account exists. You can delete your account inside the app (Settings → Delete Account). This permanently erases your profile, meals, water logs, body metrics, favourites and subscription flag from our database. Local data (photos, preferences) is removed when you delete the app. You may also email us for deletion.
Data in transit is encrypted (HTTPS/TLS). Server access is protected by Firebase security rules tied to your account, and device integrity is verified with Firebase App Check.
LifeLogix is not directed at children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect data from them.
We may update this policy; the effective date above will change and significant updates will be noted in the app. Questions or requests: lifelogix.support@gmail.com.
