TrialPocket Privacy Policy

Effective date: July 16, 2026

TrialPocket is an iPhone app for saving and organizing public clinical trial information from ClinicalTrials.gov. The app is built so that the developer does not collect, store, or transmit your personal data.

What we collect

Nothing. TrialPocket has no user accounts, no sign-in, no analytics, no advertising SDKs, no crash-reporting service, and no developer server. The app's App Store privacy label is "Data Not Collected."

Where your data lives

Everything you save in TrialPocket, including trial records, notes, source-check history, settings, and purchase state, is stored in a local database on your iPhone. The app does not sync this data to the developer or to any third party. If you delete the app, its local data is deleted with it.

Network requests the app makes

TrialPocket connects to exactly two services:

ClinicalTrials.gov. When you search for or check a study, the app sends that request directly to the public ClinicalTrials.gov API, operated by the U.S. National Library of Medicine. Those requests are subject to the National Library of Medicine's own policies. The request contains your search terms or the study identifier, not your saved notes.
Apple App Store (StoreKit). The one-time Pro purchase and Restore Purchase are processed entirely by Apple. The developer never receives your name, payment details, or Apple ID. Apple's handling of purchase data is described in Apple's privacy policy.

The app makes no other network requests.

Backups and exports

You can export your watchlist as a CSV file or a JSON backup. These files are created on your device and leave it only when you choose to share or save them. You control where they go, and you are responsible for protecting any copies you make.

Health information

TrialPocket is for public study information and research organization only. Do not enter patient data, patient identifiers, or protected health information. Because the app has no developer server, anything you type stays on your device either way, but the app is not designed or intended to hold patient records.

Children

TrialPocket is a professional reference tool and is not directed at children.

Changes to this policy

If the app ever changes in a way that affects this policy, for example by adding crash reporting, the policy will be updated here and the effective date revised before that version ships.
