Privacy Policy for ICU Basics

Effective Date: November 4, 2026

1. Introduction

Grip Theory LLC ("we," "our," or "us") respects your privacy. This Privacy Policy explains how we handle data when you use the ICU Basics application (the "App").

2. Data Collection and Usage

We do not collect, store, or share any personal information. The App operates entirely on your device. Your quiz progress, scores, flagged questions, notes, mock exam results, exam date, daily goal, study streak, and settings are stored locally and are never transmitted to our servers. We have no user accounts and no sign-in. The only data that leaves your device is the optional anonymous usage analytics described in section 4, which you can turn off.

Deleting the App deletes this information. You can also clear it at any time from Settings → Reset progress.

3. Features That Use Your Device

Some features hand data to standard parts of iOS at your request. None of them send anything to us.

• Backups. Settings → Back up progress writes your data to a file and opens the iOS share sheet so you can save it to iCloud Drive, Files, or another device you choose. Where you store it is governed by that service's privacy policy (for example, Apple's for iCloud Drive).
• Reminders and the widget. The daily study reminder is a local notification scheduled on your device at the time you choose; no notification service is involved. The optional home-screen widget reads the day's question from the App's own storage on your device.
• Sharing your score. "Share your score" creates an image on your device and opens the iOS share sheet. Nothing is shared unless you choose an app or contact to share it with.
• Email. "Report a problem with this question" and "Send feedback" open your email app with a pre-filled message addressed to us. Nothing is sent unless you choose to send it, and any email you send is used only to respond to you and improve the App.

4. Third-Party Services

The App can send anonymous usage analytics to PostHog (PostHog, Inc.) so we can see which questions and features work well and which need fixing. The same applies to the web app in your browser, which keeps its random identifier in the browser’s local storage rather than in a cookie. Analytics records a random device identifier and events such as the app being opened, a quiz being started or finished, and which question was answered and whether the answer was correct. It does not record your name, email, location, or the contents of your notes, it is not linked to you, and it is never used for advertising or tracking across other apps or websites. You can turn analytics off at any time in Settings → Your Data → Share usage analytics. When you do, the App sends one last anonymous event saying analytics was turned off, and then sends nothing more. PostHog's handling of this data is described at posthog.com/privacy. The App does not use advertising services. It is distributed through the Apple App Store and Google Play, which are governed by their own privacy policies.

This website (icubasics.com) also uses PostHog to count anonymous page views and clicks on links to the web app and the app stores, so we can see which pages help people. It sets no cookies and uses no identifier beyond a random number made for each page load and then discarded. The only thing it keeps in your browser is a note that you dismissed the app banner, if you do. It does not look up your location, though as with any website your IP address reaches the service receiving the request. If your browser sends Do Not Track or Global Privacy Control, nothing is sent.

When you follow a link from this website to the web app, the link names the page you came from, and the app’s analytics keep that page name so we can see which pages lead people to practice. The web app can also show a short, optional survey through PostHog. Your answers are stored with the analytics under the same random identifier, and you never have to answer. Please leave personal details out of any written answer.

Some pages on this website show explainer videos hosted on YouTube (Google LLC). Nothing is loaded from YouTube until you press play: before that, the page shows a picture stored on this website. When you press play, the video loads from youtube-nocookie.com, YouTube’s privacy-enhanced mode, and YouTube’s own privacy policy applies to that player. If you open a video on YouTube itself, the same applies there. The App does not show these videos.

5. Children's Privacy

Because the App does not collect any personal information, it is safe for children. We do not knowingly collect personal information from children under 13.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you by updating the "Effective Date" at the top of this policy and, if necessary, by providing notice within the App.
