Overview
Cellular Keys ("the App") is a personal health and compound tracking application for iOS, developed by John Tramell / Praxis Training LLC ("we," "us," or "our"). This Privacy Policy explains how the App handles information in connection with your use of it.
The App operates entirely on your device. It has no backend, no user accounts, and no servers that receive your data. Every entry you make — doses, protocols, health snapshots, vial records, and profile information — stays on your iPhone and is never transmitted anywhere.
Information We Do Not Collect
We do not collect, store, process, or transmit:
- Your name, email address, or any other identifying information
- Health data, medical information, or biometric measurements you enter
- Location or GPS data
- Device identifiers or advertising IDs
- Usage statistics, analytics, or crash reports
- Contact lists, photos, or any other files from your device
- Any data entered or generated within the App
There are no user accounts, no login, and no registration of any kind.
How Your Data Is Stored
All information you enter into Cellular Keys is stored locally on your device using Apple's SwiftData framework. This data:
- Never leaves your device
- Is not synced to iCloud or any cloud service
- Is not accessible to us or any third party
- Is protected entirely by your device's security model
If you delete the App, all data stored by the App is permanently deleted with it. We have no copy and no ability to recover it.
Device Security & Biometric Authentication
Cellular Keys uses Face ID, Touch ID, or your device passcode to restrict access to the App. The App automatically locks when moved to the background. We do not have access to your biometric data — authentication is handled entirely by Apple's LocalAuthentication framework and never leaves your device.
Third-Party Services
Cellular Keys does not integrate any third-party SDKs, analytics platforms, advertising networks, or data brokers. The App uses only Apple's native iOS frameworks and contains no third-party code that transmits data externally.
The Research tab contains links to external websites including PubMed, PubChem, Google Scholar, ClinicalTrials.gov, and others. When you tap a link and leave the App, you are subject to the privacy policies of those external sites. We have no control over and no affiliation with those services.
Children's Privacy
Cellular Keys requires users to confirm they are 18 years of age or older before using the App. It is not directed at children. We do not knowingly collect any information from minors. Because no data is transmitted to us from any user, no information from any user of any age reaches us.
Your Data Rights
Because we do not collect or store any of your data, there is no data for us to access, export, correct, or delete on your behalf. Your data exists only on your device, and you have full control over it at all times.
To delete all App data, uninstall Cellular Keys from your device.
Medical Disclaimer
Cellular Keys is a personal data-logging tool only. It is not a medical device, does not provide medical advice, and is not intended to diagnose, treat, cure, or prevent any disease or condition. Nothing in the App constitutes medical advice. Use of the App does not create a patient-provider relationship of any kind.
Changes to This Policy
If this Privacy Policy is updated, the revised version will be posted at this URL with an updated effective date. Because we do not collect contact information, we are unable to notify users directly of changes. We encourage you to review this page periodically.
