Frequently asked questions
How do I get access to NavICU?
NavICU is open to critical-care nurses and students. Start a 14-day free trial through Apple In-App Purchase, then continue for US $2.99/month. The trial is for eligible new subscribers; local pricing is shown in the app. No invitation or NavICU account is required to subscribe. Clinical Advisory Board participation is optional and invite-only.
How do I restore purchases or manage a subscription?
Open the App Store, tap your account, then Subscriptions — or, in NavICU, go to Settings → Manage subscription. Subscriptions are billed through your Apple ID and auto-renew until cancelled; you can cancel anytime in your Apple ID settings.
How do I delete my account and data?
In NavICU, go to Settings → Delete account. This permanently deletes your account and profile data. You can also email us and we will delete your data on request. Account deletion does not cancel your Apple subscription; manage or cancel it separately in your Apple Account settings.
Where do the medical facts in the app come from?
Every calculator, score, and learning card in NavICU cites its sources — the original studies plus free full-text references such as StatPearls and official clinical guidelines. You can browse the full list inside the app under Settings → References & Sources, or on any calculator or learning card.
I found a content error — what should I do?
Please email us the details. We take clinical accuracy seriously and review every report.
Privacy Policy
Last updated: September 21, 2026
Streamwalkers Corporation ("we", "us") built NavICU. This policy explains what we collect and why.
Information we collect
Account information (for invite-only professional accounts): your name, email address, and profession, plus optional details you choose to provide such as phone number, city or region, employer or school, and training stage. Advisory Board applications also include the reason for applying and professional experience you submit. We use this information to manage your professional account and the optional Advisory Board program. A NavICU account or invitation is not required to purchase a membership.
Usage analytics: we collect pseudonymous app-usage events (for example, which screens are opened) to improve the app. Events include a random installation identifier, session identifiers, and professional role or specialty when supplied. For signed-in users, these events can be linked to the account. We do not use this information for cross-app advertising tracking. You can turn analytics off anytime in Settings → Privacy.
On-device data: your study progress and any entries you make in the optional dialysis self-log are stored only on your device and are not transmitted to us. The Max study guide runs on your device and does not send your questions to us or any third party.
How we use information
To operate and improve NavICU, manage your account, provide support, and keep the service secure. We do not sell your personal information.
Sharing
We share information only with service providers that host our systems on our behalf (for example, our secure cloud database), and only as needed to run the app. We may disclose information if required by law.
Data retention and deletion
We keep account data for as long as your account is active. You can delete your account and profile data at any time in Settings → Delete account, or by emailing us.
Children
NavICU is intended for healthcare professionals and students and is not directed to children under 13.
