Privacy Policy

Effective date: September 12, 2026 · Last updated: September 28, 2026

Short version: LogMog stores all your data locally on your device using Apple's UserDefaults. We collect nothing, transmit nothing, and sell nothing.

1. Who we are

LogMog is an iOS application developed by Chuck Silver. Questions about this policy? Contact Support.

2. Data we collect

We collect no personal data. LogMog has no backend server, no account system, and no analytics SDK. Everything you enter — your weight, height, age, sex, activity level, and goal — is stored exclusively on your iPhone using Apple's UserDefaults. No data ever leaves your device.

3. Health & fitness information

LogMog allows you to enter personal health metrics such as weight, height, and age to calculate BMI, TDEE, and macro targets. This information is:

Entered manually by you
Stored only on your device (UserDefaults)
Never transmitted to any server or third party
Not used for advertising, analytics, or any purpose other than displaying your results

LogMog does not integrate with Apple HealthKit and does not read or write any data to Apple Health.

4. Local notifications

If you grant permission, LogMog schedules a weekly local notification (every Sunday at 9 AM) reminding you to update your stats. These notifications are generated and delivered entirely on your device by iOS. No notification content is sent to any server.

5. Third-party services

LogMog uses no third-party analytics, advertising, or tracking services. There are no third-party SDKs embedded in the app.

6. Data sharing

We do not sell, trade, or share your data with anyone — because we never have access to it in the first place.

7. Data retention & deletion

All app data is stored in your device's local UserDefaults. You can delete all data at any time by deleting the LogMog app from your iPhone, which permanently removes all associated data from your device.

8. Children's privacy

LogMog is not directed at children under 13. We do not knowingly collect any information from children.

9. Changes to this policy

If we make material changes, we will update the effective date above and note the change in the app's release notes. Continued use of the app after changes constitutes acceptance of the updated policy.
