Privacy Policy for CaloZ

1. What CaloZ stores

1.1 Your account

You sign in with Google or with an email address and password. Our sign-in provider, Firebase Authentication (Google), keeps your email address, a random account ID and, for Google sign-in, the name and profile picture on your Google account. We use the email to show you which account you're signed in to and to answer support requests.

1.2 Your health and fitness entries

• Profile: starting weight, height, age, sex, activity level and units.
• Goals: your target weight and the plan you set.
• Logs: foods and calories, activities and calories burned, weigh-ins, and drinks (name, alcohol percentage, volume, quantity and price).

Where these are kept depends on your plan:

• Free: on your phone only, in the app's private storage. They are not sent to us.
• Premium: in our Cloud Firestore database (Google Cloud), tied to your account ID, so they sync to any phone you sign in on. When you upgrade, your phone's entries are copied up; if Premium ends, they're copied back to the phone.

1.3 Your subscription

Google Play takes the payment; we never see your card. We store your subscription status, the Google Play purchase token and when it was last checked, so the app knows whether to unlock Premium. If a purchase fails to verify, we log the error with your account ID so we can fix it.

1.4 What CaloZ does not collect

No location, contacts, photos, camera, microphone, Google Fit, Health Connect or Apple Health data. No analytics or tracking SDK of our own, and no crash-reporting service. We don't sell or rent your data.

2. Advertising (free plan only)

The free plan shows banner ads from Google AdMob. To serve and measure them, Google's ad SDK collects your device's advertising ID, IP address, device and app information, and ad interactions, as described in How Google uses information from sites or apps that use its services. In the EEA, UK and Switzerland, the app asks for your consent first using Google's consent form; you can change your choice any time under ⋮ menu → Ad privacy choices. Elsewhere you can reset or delete your advertising ID in Android Settings → Privacy → Ads.

Your health and fitness entries are never shared with AdMob or any advertiser. Premium shows no ads, and the ad SDK isn't started for Premium users.

3. Who else handles your data

• Google (Firebase Authentication, Cloud Firestore, Cloud Functions): sign-in, Premium cloud storage and purchase checks. Data may be stored on Google servers outside Canada.
• Google Play: payments and subscriptions.
• Google AdMob: ads on the free plan, as above.

We'd also disclose data if the law required it. Nobody else gets it.

4. Security

Data travels to Google over encrypted connections and Google encrypts it at rest. No system is perfectly secure, but we keep what we store small.

5. How long we keep it, and how to delete it

We keep your account and any cloud entries until you delete them. You can delete single entries in the app at any time.

• In the app: ⋮ menu → Delete Account. After you confirm who you are, it deletes your sign-in account, your cloud entries and the entries stored on that phone, straight away.
• Without the app: follow caloz-delete.html and we'll delete everything within 30 days.

Deleting your account doesn't cancel a Premium subscription; cancel it in Google Play → Payments & subscriptions. Google keeps its own payment records under its own policy.

6. Your rights

Wherever you live, you can ask us for a copy of what we hold about you, to correct it, or to delete it. If you're in the EU, UK, California or another place with privacy laws, those laws give you these rights too, and you may complain to your local privacy regulator. We handle your entries because you asked the app to track them (and, for Premium, to sync them), and serve personalised ads only with consent where the law requires it. Email ziehro@gmail.com and we'll reply within 30 days.

7. Age

CaloZ is for adults 18 and over. We don't knowingly collect data from anyone younger; if you think a child has an account, email us and we'll delete it.

8. Not medical advice

Calorie targets and calculators are estimates for general information. Talk to a doctor before starting a diet or exercise plan.

9. Changes

If what CaloZ collects changes, we'll update this page and the date at the top before the app update ships.
