ZivoLog (“the app”, “we”, “us”) is a privacy-first step-tracking and health-logging app published by Examinds. This policy explains what data the app handles, where it lives, and your choices. The guiding principle: your health data stays on your device unless you explicitly turn on a feature that moves it, and we never sell your data.
ZivoLog is published by Examinds. Contact: sbala@sriran.com.
With your permission, ZivoLog reads from Apple Health (HealthKit): step count, distance, active energy, flights climbed, active time, blood pressure, sleep duration, resting heart rate, and workouts. With your permission it can also write blood pressure readings you log back to Apple Health.
The optional weekly AI summary is generated entirely on your device using Apple’s on-device foundation models. Your health figures are not uploaded to generate it.
If you turn on iCloud sync, your logged data is synchronized through your own iCloud account using Apple’s CloudKit. In that case the data is stored in your private iCloud database under Apple’s terms; we do not have access to it and it is not shared with us or other users. Sync is off by default and you can disable it at any time in the app.
If you create an account, ZivoLog uses Sign in with Apple and/or Google Sign-In via Firebase Authentication (Google). These services receive the identifiers needed to authenticate you (e.g. an Apple/Google user identifier, and for Google sign-in the email/profile you authorize). You can also use the app as a guest without an account.
Premium subscriptions are processed by Apple through the App Store and managed with RevenueCat (subscription analytics and receipt validation). RevenueCat receives an opaque user identifier and your subscription status — never your health data. Apple processes the actual payment under Apple’s terms; we never receive your payment card details.
The free tier may show ads via Google AdMob. With your consent under Apple’s App Tracking Transparency (ATT) prompt, AdMob may use advertising identifiers to show and measure ads; if you decline, you receive non-personalized ads. Ads and any associated identifiers are handled by Google per Google’s Privacy Policy. Premium subscribers see no ads. We do not share your health data with ad networks.
The app does not run its own analytics SDK for your activity. Standard crash/usage reporting may be provided by Apple if you have opted into sharing diagnostics with developers in iOS Settings; this never includes your health values.
Data you log lives on your device (and, if you enabled it, your iCloud account). You can delete individual entries, delete a profile’s data, or use Delete All Data in the app. Note: small non-health “deletion markers” (record/profile identifiers, a kind, and a date — never health values) are retained to keep deletions consistent across your synced devices, as disclosed in the app’s Privacy screen.
ZivoLog is not directed to children under 13 and we do not knowingly collect their data.
Depending on your region (e.g. GDPR/CCPA), you may have rights to access, correct, or delete your data. Because health data is stored on your device/your iCloud, you control it directly in the app and in iOS Settings. For questions, contact sbala@sriran.com.
We may update this policy; the “Last updated” date will change and material updates will be surfaced in the app where appropriate.
