This Privacy Policy explains how Patch Tracker handles user information. We take privacy seriously. The App is designed so that all personal and health-related data remain entirely on your device. We do not collect, transmit, or store any data on external servers.
The App does not collect, process, or transmit any personal data, health data, or usage analytics.
We do not require user registration, accounts, or online connectivity.
All entered information (such as insulin usage, estimated remaining insulin, or patch expiration dates) is stored only on your device's local storage.
All data you enter stays on your device.
You have full control over your information — you can edit, or delete it at any time through your operating system's data management tools.
Deleting the App permanently removes all stored data. We cannot recover it.
If you choose to enable it, the App can sync insulin delivery data to Apple Health on your device.
This integration is optional and only occurs locally on your device. We do not access or collect any data from Apple Health.
Data synced to Apple Health is governed by Apple's privacy policies. You can disable this integration at any time in the App settings or in your device's Health app settings.
The App does not use cloud backup, analytics, advertising, or tracking tools.
It does not connect to any third-party services, APIs, or databases (except Apple Health if you enable it).
We cannot access, view, or share your data under any circumstance.
The App may display informational estimates of insulin usage and patch status based on your manual inputs. These estimates are for personal tracking purposes only and must not be used as medical advice or relied upon for dosing decisions. Always consult a qualified healthcare provider for medical guidance.
The App is not directed toward children under 13 years of age. We do not knowingly collect any information from anyone, including minors.
Because all data remains local:
The App may display references or external links (e.g., informational resources or manufacturer sites). We are not responsible for the content or privacy practices of those third parties.
We may update this Privacy Policy periodically. Any changes will be reflected in the updated version of the App. We encourage users to review this Policy occasionally for the latest information.
