Privacy Policy

1. Who We Are

Fasting Diary ("the App", "we", "our") is an Android intermittent fasting tracker developed and operated by Two Quarters Sdn Bhd, reachable at support@fastingdiary.fit. The App is available on Google Play under the package ID com.fastingdiary.app.v2. Our website is fastingdiary.fit.

2. Information We Collect

2.1 Information You Provide

• Account details: Your email address and a password (stored securely by Firebase Authentication — we never see your password), or, if you sign in with Google, your Google account email and name.
• Profile: Nickname, height, weight, fasting goal, experience level, and optional target weight and target date.
• Fasting records: Start times, end times and fasting plan selections.
• Health logs: Body weight entries, journal entries (mood, notes, wins and challenges) and water intake you record in the App.
• Preferences: App settings such as chosen fasting plan, notification preferences, reminder times, water goal and theme.
• Profile photo: If you add one, it stays on your device only and is not uploaded.

2.2 Information Collected Automatically

• Crash reports and diagnostics: If the App crashes, anonymized diagnostic data (device model, OS version, stack trace) may be collected to help us fix bugs. This data does not identify you personally.
• Usage analytics (aggregated): We may collect anonymized, aggregated information about how features are used (e.g., which fasting plan is most popular) to improve the App. Individual sessions are not tracked or linked to you.

2.3 Information We Do NOT Collect

• We do not collect precise GPS location.
• We do not access your contacts, camera, microphone, or files unless a feature you explicitly activate requires it.
• We do not sell your data to third parties.

3. How We Use Your Information

We use the data described above for the following purposes:

• To provide and operate the core features of the App (timer, history, analytics).
• To create and secure your account, and to back up your data so you can restore it on a new or reinstalled device.
• To improve App stability and fix bugs using crash reports.
• To understand how the App is used in aggregate and make improvements.
• To process in-app purchases and manage premium subscriptions (handled by Google Play billing — we do not receive your payment card details).
• To respond to your support requests when you contact us.

4. Data Storage and Security

Your data is stored on your device and backed up to your Fasting Diary account using Google Cloud Firestore, hosted in Google’s Singapore region. The backup lets you restore your history when you sign in on a new device or reinstall the App.

Your backup can only be read or changed by you while signed in to your account — access rules prevent anyone else, including other users, from reading it. Data is encrypted in transit (HTTPS/TLS) and at rest by Google Cloud.

5. Third-Party Services

The App integrates with the following third-party services, which have their own privacy practices:

• Google Play Billing — manages in-app purchases and subscriptions. See Google's Privacy Policy.
• Firebase (Google) — Firebase Authentication (sign-in with email or Google), Cloud Firestore (your data backup), Crashlytics (crash reports) and Analytics (aggregated usage statistics). See Firebase Privacy Information.
• Google Sign-In — if you choose “Continue with Google”, Google shares your email address and name with us to create your account.

We do not share your personal data with advertisers or data brokers.

6. In-App Purchases and Subscriptions

Fasting Diary offers a free tier and an optional premium subscription with a 7-day free trial. All billing is handled by Google Play. We do not receive or store your credit card or payment information. You can manage or cancel your subscription at any time through your Google Play account settings.

7. Children's Privacy

Fasting Diary is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. Intermittent fasting is not recommended for minors without medical supervision. If we learn that a child under the applicable age has provided personal information, we will delete it promptly. If you believe a child has used the App inappropriately, please contact us at support@fastingdiary.fit.

8. Your Rights and Choices

Depending on your location, you may have the right to:

• Access, correct, or delete personal data we hold about you.
• Opt out of analytics data collection (via device-level or app-level settings).
• Request a copy of your data in a portable format.
• Withdraw consent where processing is based on consent.

Deleting your account: you can delete your account and all of its data at any time in the App (Settings → Delete Account), or by following the steps on our account deletion page. This permanently deletes your account, your backup and the data on that device.

You can export your data as a CSV file in the App (Settings → Export as CSV). For any other data requests, contact us at support@fastingdiary.fit.

9. Data Retention

Your account and backup are kept until you delete your account. Signing out removes the data from that device but keeps your backup so you can restore it later. Anonymized crash and diagnostic reports may be retained for up to 12 months to support ongoing bug-fix and quality efforts, after which they are deleted.

10. International Users

Fasting Diary is developed and operated from Malaysia. Your backup is stored in Google Cloud’s Singapore region, and some services (such as Firebase Crashlytics and Analytics) may process data in the United States or other countries. By using the App, you acknowledge that your data may be processed in jurisdictions with different data protection laws than your own. We take reasonable steps to ensure appropriate safeguards are in place.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page and, where the changes are material, notify you through an in-app notice. Continued use of the App after changes are posted constitutes acceptance of the updated policy.
