Your digestive health
stays strictly on your device.

GutMark is a private, local-first stool and bowel tracking journal. OrbonTech does not collect, transmit, store, sell, or share your personal health observations.

Zero Data Collection

GutMark does not require an account, username, email, or login. All stool types, Bristol scale classifications, urgency, notes, timestamps, and export reports exist solely on your local device storage.

No Cloud Sync or Third-Party Analytics

There are no tracking SDKs, advertising frameworks, or remote analytics installed in GutMark. We do not use third-party telemetry. What happens on your device stays on your device.

Face ID & Biometrics

If you enable Face ID or Passcode protection in Settings, the authentication is handled exclusively by Apple's secure enclave on your device. GutMark never accesses or stores your biometric credentials.

In-App Purchases

GutMark Pro is a one-time non-consumable purchase handled entirely by Apple StoreKit 2. We do not process, store, or receive your payment card or billing information.

Medical Disclaimer

GutMark records observations you enter. It does not diagnose or treat any medical condition. Always consult a qualified clinician about gastrointestinal health concerns.
