Merra

Privacy Policy

Last updated May 18, 2026

Merra is a medication and wellness tracker built by Studio. We designed it to be local-first and privacy-respecting. This policy explains exactly what data Merra handles, where it lives, and the controls you have over it.

The short version

  • Your medication data is stored on your device. Optional iCloud sync uses Apple's end-to-end-encrypted CloudKit; we never see it.
  • We do not sell, rent, or share your personal information with third parties for advertising or any other purpose.
  • Merra does not track you across apps or websites. There are no advertising identifiers and no tracking domains.
  • Anonymous analytics and crash reports are opt-in. You can turn them off at any time from Settings → Privacy inside the app.
  • You can export, transfer, or delete your data at any time, directly from the app.

Data Merra handles

Health & medication data

Medications, schedules, dose history, adherence records, inventory, photos of prescription labels, household profiles, and emergency contacts you choose to enter.

  • Where it lives: on your device, in Apple's SwiftData store.
  • iCloud sync (optional): if you enable it, your data is synchronized across your Apple devices through CloudKit using your iCloud account. CloudKit data is encrypted in transit and at rest. We have no access to your CloudKit container.
  • Linked to your identity: no.
  • Used for tracking: no.

Photos you select

If you scan a prescription label or attach a photo to a medication, that image is stored locally with your medication record. Optical character recognition (OCR) happens entirely on-device using Apple's Vision framework. Photos never leave your device unless you opt into iCloud sync.

Anonymous analytics (opt-in only)

If you opt in, Merra collects anonymized product-interaction events (such as "dose taken", "medication created", "screen viewed") and crash reports via PostHog. These events:

  • Never include medication names or other identifying details.
  • Are not linked to your identity or to any persistent advertising ID.
  • Are not used for tracking you across other apps or websites.
  • Are used only to find bugs and understand which parts of the app are working.

You can turn analytics, crash reporting, and personalization off individually at any time from Settings → Privacy.

App settings

Merra uses iOS's standard preference storage (UserDefaults) to remember your settings, such as notification preferences and consent choices. This data stays on your device.

What Merra does not do

  • We do not require an account or sign-in.
  • We do not collect your name, email, phone number, or location.
  • We do not contain third-party advertising SDKs.
  • We do not use any tracking domains.
  • We do not use your data to train AI or machine-learning models.

Apple HealthKit

Merra may request optional access to Apple HealthKit to read or write medication and dose data. Any HealthKit data is governed by Apple's HealthKit policies in addition to this one, is stored only in your iOS Health app, and is never transmitted off your device by Merra.

Notifications

With your permission, Merra schedules local notifications for dose reminders. These notifications are generated on your device by iOS — they do not pass through any Studio server.

Children's privacy

Merra is not directed to children under 13. If you are a caregiver managing medications for a dependent, you are responsible for the data you enter.

Your rights

Because Merra is local-first, you have direct control of your data at all times:

  • Export a full backup of your data from Settings → Backup.
  • Delete all data permanently from Settings → Privacy → Delete All Data.
  • Disable analytics, crash reporting, and personalization independently.
  • Disable iCloud sync in iOS Settings → [Your Name] → iCloud → Merra.

Changes to this policy

If we materially change how Merra handles data, we will update this page and bump the "Last updated" date above. Significant changes will also be surfaced in the app itself.
