Cento App Privacy 

Cento Care is a service operated by FIRST TO SMILE HOLDINGS LTD (“Cento”, “we”, “us”, or “our”). This Privacy Statement explains how the Cento mobile app collects, uses, stores, and protects information about you when you use the app.

This Privacy Statement applies specifically to the Cento mobile app and its features, including manual tracking, device and platform integrations, and connected wellness services.

1. What the app is for

The Cento app is designed to help users track wellness-related information, such as activity, sleep, feelings, symptoms, and health signals including blood pressure.

The app is for wellness, education, and self-management purposes only. It is not a medical device and is not intended to diagnose, treat, cure, prevent, or monitor any disease or medical condition. The app does not replace a doctor or other qualified healthcare professional. Always seek professional medical advice for diagnosis, treatment, or medical decisions.

2. Who can use the app

The app is intended for adults only. You must be at least 18 years old, or the age of majority in your jurisdiction, to use the app.

3. Information we collect

We may collect the following categories of information when you use the app:

Information you provide directly

• Name, email address, login details, and account information

• Profile information such as age range, sex, height, weight, goals, and preferences

• Information you manually log in the app, such as activity, mood, sleep, symptoms, blood pressure, notes, and other wellness or lifestyle entries

• Messages or support requests you send to us

Information from connected platforms and services

If you choose to connect them, we may receive data from:

• Apple Health / HealthKit

• Android Health / Health Connect

• Google Fit, where still supported or used by your device or account

• Garmin Connect

Depending on the permissions you grant, this may include data such as:

• Steps and activity

• Workouts and exercise sessions

• Distance, calories, heart rate, sleep, and related fitness or wellness data

• Blood pressure or other health measurements made available through the connected platform

• Device-related timestamps and metadata needed to sync and display your data

We only access the categories of data you authorise. You can revoke access at any time in your device or account settings.

Automatically collected technical information

• App version, device type, operating system, language, time zone

• Log data, crash reports, diagnostics, and basic usage information

• Identifiers needed to keep your account secure and the app functioning

We do not use health data for advertising, profiling, or sale to data brokers. 

4. How connected data works

If you connect Apple Health, Android Health / Health Connect, Google Fit, or Garmin Connect, the connection is optional and based on your permission.

When you connect one of these services:

• the app reads only the data types you authorise

• we use that data to display trends, summaries, logs, and wellness insights inside the app

• disconnecting the integration stops future syncing, although data already imported into your Cento account may remain unless you ask us to delete it

Apple Health / HealthKit

Health data accessed through Apple Health is used only to provide and improve your experience in the Cento app. It is not used for advertising, marketing, or use-based data mining. 

Android Health / Health Connect

Health Connect data is accessed only for the app’s wellness features and only where relevant to the app’s core functionality. 

Google Fit

Where Google Fit is used, access is limited to the scopes and data you authorise. Google Fit APIs are being deprecated in 2026, and we may migrate Android integrations to Health Connect over time. 

Garmin Connect

Where you connect Garmin Connect, data submitted through that integration is submitted to Cento, not to Garmin. Garmin is not responsible for how Cento handles that data. We do not sell, rent, or transfer Garmin user data except as necessary to provide the app, with your consent, or as required by law. 

5. How we use your information

We use your information to:

• create and manage your account

• provide the app’s tracking, logging, syncing, and visualisation features

• show your trends, summaries, history, and wellness insights

• personalise your in-app experience

• maintain, secure, troubleshoot, and improve the app

• respond to support requests

• comply with legal obligations

• enforce our terms and protect the safety, rights, and integrity of users and the app

We may also use de-identified or aggregated information to understand product usage, improve features, and analyse performance, provided that such information does not reasonably identify you.

6. No sale of data and no advertising use of health data

We do not sell your personal data.

We do not use your health or fitness data for advertising, marketing, or cross-context behavioural advertising.

We do not share health data with data brokers.

We do not allow third parties to use your health data for their own advertising or marketing purposes.

7. When we may disclose information

We do not disclose your personal data or health data except in the following limited circumstances:

• to service providers that help us operate the app, such as hosting, storage, analytics, customer support, security, and infrastructure providers, under contractual confidentiality and data protection obligations

• where you ask us to connect or sync with a third-party platform or service

• if required by law, regulation, court order, or lawful government request

• to protect the rights, safety, or security of users, Cento, or others

• in connection with a corporate transaction such as a merger, acquisition, or sale of assets, subject to applicable law

Where possible, we limit disclosures to what is necessary.

8. Legal basis for processing

Where UK GDPR, EU GDPR, or similar laws apply, we generally process personal data on the following bases:

• performance of a contract, to provide the app and its features

• legitimate interests, such as security, fraud prevention, service improvement, and app administration

• consent, where required, including for connecting health platforms or processing certain health-related data

• legal obligation, where we must comply with law

Where we process health-related data, we do so with your consent or another lawful basis permitted by applicable law.

9. Data retention

We keep your information only for as long as reasonably necessary for the purposes described in this Privacy Statement, including to provide the app, comply with legal obligations, resolve disputes, and enforce our agreements.

If you delete your account, we will delete or anonymise your information within a reasonable period, unless we are required or permitted by law to keep certain records.

10. Security

We use reasonable technical and organisational measures designed to protect your information, including access controls, encryption in transit where appropriate, and security monitoring.

No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

11. International data processing

Cento may process and store information in countries outside your home jurisdiction. Where required, we use appropriate safeguards for international data transfers under applicable law.

12. Your choices and rights

Depending on your location, you may have rights to:

• access your information

• correct inaccurate information

• request deletion

• withdraw consent

• object to certain processing

• request restriction of processing

• receive a copy of certain data in portable form

You may also:

• disconnect Apple Health, Health Connect, Google Fit, or Garmin Connect at any time through your device, app, or account settings

• request account deletion by contacting us

• opt out of non-essential communications

13. Children

The app is not directed to children, and we do not knowingly collect personal data from children.

14. Changes to this Privacy Statement

We may update this Privacy Statement from time to time. If we make material changes, we will update the “Last updated” date and, where required, provide additional notice.
