Privacy policy
Last updated: 13 November 2026
This policy explains how the CaloriesIO apps and the website caloriesio.app handle information. The short version: your health data stays on your own devices, and we do not receive it.
1. Who we are
CaloriesIO is provided by Born in the Cloud Ltd, a UK limited company ("we", "us"). We are the controller of any personal data described in this policy. You can contact us at support@caloriesio.app.
2. What the apps do with your data
CaloriesIO reads information from Apple Health (iPhone) or Health Connect (Android), with your permission, and shows it back to you. It does not have user accounts, and it does not send your health data to us or to any server we run.
| Information | Why it is used | Where it goes |
|---|---|---|
| Calories you have eaten (dietary energy) | To show calories in | Read on your device only |
| Active and resting energy burned | To show calories out and net | Read on your device only |
| Weight and body fat | To show your progress screen | Read on your device only |
| Workouts | To show the workouts screen | Read on your device only |
| Details you enter in the app, such as calorie targets and a goal weight and date | To compare your numbers with your goals | Stored on your device only |
You control which categories the app may read. You can change or withdraw permission at any time: on iPhone in Settings › Health › Data Access & Devices, and on Android in Health Connect settings. The app does not write health data back unless a feature clearly says so.
3. Watch apps and widgets
The Apple Watch and Wear OS apps and the home screen widgets show numbers that your phone has already calculated. Your phone and watch exchange this directly with each other, on your own devices, using the systems built into iOS, watchOS, Android and Wear OS. It does not pass through us.
4. What we do not do
- We do not sell your data.
- We do not use health data for advertising, marketing or data brokering.
- We do not share health data with third parties.
- We do not use third-party analytics or advertising tools in the apps.
5. Purchases and subscriptions
If you buy a subscription, the purchase is processed by Apple (App Store) or Google (Google Play) under their own privacy policies. We receive confirmation that a purchase or subscription is active, but we do not receive your payment card details.
6. This website
The website uses no cookies, no analytics and no advertising tools. It is hosted by Cloudflare, which may process technical information such as your IP address in server logs in order to deliver the site and keep it secure. See Cloudflare's privacy policy.
7. Contacting us
If you email us for support, we receive your email address and whatever you tell us. We use it only to reply to you and to improve the app, and we keep it for as long as needed to deal with your request and any follow-up, normally no longer than 24 months. Our lawful basis is our legitimate interest in responding to people who contact us. We do not ask you to send health data by email, and we suggest you don't.
8. Keeping and deleting your data
Data inside the apps stays on your device. Deleting the app removes the targets and settings you entered. Your data in Apple Health or Health Connect belongs to those services and is managed by you in their settings, not by us.
9. Your rights
Under UK data protection law you have the right to ask us what personal data we hold about you, to have it corrected or deleted, to object to or restrict how we use it, and to receive a copy. Because the apps do not send us your health data, the only personal data we are likely to hold is your support correspondence. To use any of these rights, email support@caloriesio.app. If you are unhappy with how we have handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.
10. Security
Your data stays in the protected storage of your own devices, under the security of your operating system, including any passcode or biometric lock you use. Emails to us travel over encrypted connections where your email provider supports it.
11. Children
CaloriesIO is not intended for anyone under 18, and we do not knowingly collect information from children.
12. Not medical advice
CaloriesIO is an information tool. It does not diagnose, treat or give medical advice. Speak to a doctor or registered dietitian before making significant changes to your diet or exercise.
13. Changes to this policy
If we change how the apps or website handle information, we will update this page and the date at the top. If a change is significant, we will also tell you in the app.
