Injection TrackerInjection TrackerInjection Reminder · Effective date: October 4, 2026
Summary: Injection Reminder, made by Zazen Technology Group, LLC, keeps the health information you enter on your device and, when enabled, in your private iCloud account. The App has no developer-operated account or health-data server. Optional PostHog product analytics start after you accept this policy and can be disabled in Settings. They exclude individual medication and injection records. RevenueCat processes subscription and purchase status.
Medication names, doses, units, schedules, injection dates and times, injection sites, pen tracking details, streak values, notes, and notification content are stored locally on your device and may sync through your private iCloud account when iCloud is available. We do not send this information to PostHog or otherwise receive or collect it.
After you accept this policy, the App uses PostHog, Inc. to understand setup and improve the App unless you disable optional product analytics in Settings. Events may include onboarding screens reached, notification permission outcome, paywall and subscription outcomes, one-time aggregate milestones indicating that the installation reached its first, second, or third taken-dose log, a selected Customer Center cancellation-feedback option, app and build version, general device and operating-system metadata, session information, event receipt time, and a randomly generated installation identifier. This identifier is pseudonymous, not fully anonymous. The App may share it with RevenueCat to associate subscription lifecycle events with the same installation. Medication names, doses, schedules, dates, sites, symptom definitions, symptom check-ins, severity ratings, notes, and individual history records are excluded. PostHog processes these events under its privacy policy. You can disable product analytics in Settings, which stops future collection, clears the local analytics identifier and queue, and removes the PostHog identifier attribute from RevenueCat.
The App uses RevenueCat, Inc. to validate purchases, subscriptions, trial eligibility, and feature access. RevenueCat may process an app-generated customer identifier, purchase and subscription status, app version, and device or store metadata under its privacy policy. The App does not send medication, schedule, injection, site, dose, symptom, severity, or notes data to RevenueCat.
The App does not display third-party ads and does not sell or rent personal data. We do not share medication, dose, schedule, injection, site, symptom, severity, or note data for advertising. PostHog product analytics are not used for advertising. Automatic screen capture, session replay, and collection of screen contents are disabled.
Reminders are scheduled locally through Apple's notification system and use generic wording by default. Widgets and Live Activities can appear outside the unlocked App. Detailed widget content is off by default and can be enabled in Privacy & Support. The widget does not record an injection; it opens the App so you can choose and confirm the site you actually used. iOS privacy and notification-preview settings also affect what other people can see.
If you export your history, a CSV file is created on your device and shared only through the destination you choose in the system share sheet. Once shared, that copy is governed by the receiving service's policies.
Your injection records and settings may sync between devices through Apple's iCloud and may also be included in device backups that you control through iOS. iCloud sync and backups are managed by Apple under Apple's terms, not by us, and are not accessible through a developer-operated health-data server.
You can delete individual logs or medications in the App, and those deletions sync to your other devices when iCloud is available. Deleting the App removes its local cache but may not delete data stored in your private iCloud account; manage that data through Apple's iCloud storage settings. Pseudonymous analytics and subscription records are retained according to the applicable processor's settings, privacy policy, and legal obligations. Because the App does not create a developer account, contact us if you need help locating or requesting deletion of processor data.
The App is not directed to children under 13, and we do not knowingly collect personal information from children.
If the App's data practices ever change, this policy will be updated and the effective date revised before the change takes effect.
