Handler Labs

Per-app privacy policies

Handler Labs · Privacy Policy

Effective date: May 24, 2026

1. Who we are

Handler Labs is an independent iOS software studio that builds training-log apps for service dog handlers. We can be reached at [email protected].

2. Our privacy principle

Your data lives in your iCloud account. We cannot see it, access it, or sell it.

Every piece of training and health data you log stays in your private Apple CloudKit database, which is the same infrastructure Apple uses for your own iCloud data. Handler Labs has no server, no database, and no account system. We have no technical means of accessing your records even if we wanted to.

3. What data the app stores

Depending on the app, this may include:

  • Dog profiles (name, breed, date of birth, photo)
  • Training session records (date, task type, duration, outcome, notes)
  • Alert events (timestamp, result, associated readings, notes)
  • Scent sample inventory records
  • Handler notes and custom fields

All of this is stored with iOS Data Protection (encrypted at rest when your device is locked) and synced via your private CloudKit database. Only devices signed in with your Apple ID can access it.

4. What we do not collect

  • No user accounts or registration; there is no Handler Labs account system
  • No names, email addresses, or contact information sent to us
  • No location data
  • No advertising identifiers (IDFA/IDFV)
  • No device fingerprinting
  • No selling, licensing, or brokering of any data to third parties, ever

5. Analytics

The app sends anonymous usage events to TelemetryDeck. These events are things like "a session was logged" or "the export feature was used." They contain no health data, no personal information, no dog names, and no record content of any kind.

TelemetryDeck uses a privacy-preserving architecture that hashes any device identifiers before transmission, making individual users unidentifiable. We use these aggregate signals only to understand which features are used and to prioritize development.

6. In-app purchases

Pro upgrades are processed entirely by Apple through Apple StoreKit. We receive a confirmation that a purchase was made and its entitlement status. We never receive your payment details, Apple ID, or billing information. Purchase receipts are validated locally on-device or via Apple's servers; no purchase data passes through Handler Labs infrastructure.

7. Data sharing and export

When you export a PDF report or a JSON backup, that file is created entirely on your device and shared only when you choose to, using the iOS share sheet. Nothing is automatically uploaded or sent anywhere. You control every export.

8. Your control and data deletion

  • Delete records: Delete individual records or all data from within the app. Deletion propagates to your iCloud private database.
  • Delete the app: Deleting the app removes local data. To also remove iCloud data, delete records in-app first, or go to Settings → [your name] → iCloud → Manage Account Storage and remove app data there.
  • Analytics opt-out: If you prefer no analytics, contact us at [email protected] and we will provide instructions for the current app version.

9. Children's privacy

Some apps in the Handler Labs portfolio may be used by parents or caregivers on behalf of a minor (for example, logging an autism service dog's work). The app does not knowingly collect personal information directly from children. Because no data is transmitted to Handler Labs regardless of who uses the app, there is no special handling required. Your child's information stays in your iCloud account, under your control.

If you believe we have inadvertently received personal information about a child, contact us at [email protected] and we will address it promptly.

10. Changes to this policy

If we make material changes to this policy, we will update the effective date above and, where feasible, provide notice within the app. Continued use of the app after the updated policy is posted constitutes acceptance of the changes.
