Effective Date: May 17, 2026
App: Hypna: Anesthesia Case Log
Developer: Constantine Skenderis
Summary
Hypna is a private case-logging tool for anesthesia providers. Your data
stays on your device.** Hypna does not collect, transmit, sell, or share
any personal information or health data.
What Hypna stores
All cases, drafts, profile information (name, NPI, DEA, state licenses,
certifications, saved locations, profile photo), and reminders you enter
into Hypna are stored locally on your iPhone using Apple’s SwiftData
framework. We never see this data. It does not leave your device unless
you explicitly export it as a PDF, CSV, Excel, or Word file and choose
to share that file via iOS’s share sheet.
What Hypna does NOT do
– We do not have a backend that stores user data.
– We do not collect analytics, telemetry, crash reports, or usage data.
– We do not include third-party advertising, tracking SDKs, or trackers.
– We do not sell, rent, share, or disclose any information to third parties.
– We do not require an account, login, or any sign-in.
Network connections
Hypna makes exactly one type of outbound network request: a check at
launch against our Supabase server to determine the latest published
version of the app. This request sends no personal information —
it asks only “what is the latest iOS version?” and receives a version
number in response. The request includes no identifiers, no analytics,
and no usage data.
Permissions
Hypna may request the following iOS permissions, all of which are optional:
– Photo Library: only used if you choose to set a profile picture. The
image you select is stored on your device and never transmitted.
– Motion & Fitness: used for subtle parallax effects on background
imagery. No motion data is recorded or transmitted.
– Notifications: used only for the reminders you configure inside
Hypna (e.g., reminders to finish draft cases).
You may revoke any of these at any time in iOS Settings → Hypna.
Children’s privacy
Hypna is intended for anesthesia providers (typically licensed medical
professionals over 18). Hypna does not knowingly collect any information
from children.

Frequently Asked Questions
Is my data private?
Yes. All cases, drafts, and profile information stay on your iPhone.
Hypna does not have a backend that stores user data, and does not collect
analytics or share anything with third parties. See the
privacy policy above for details.
How do I add a case?
Tap the + button on the Today tab or the Cases tab. Fill in the
fields, then tap Save. To save a case for later, tap Save as
Draft — it’ll appear in your draft list on the Today widget and
in the Cases tab.
What exports are supported?
PDF (branded with your name and credentials), CSV, Excel (.xls), and
Word (.rtf). All exports are generated on-device.
How does the widget work?
Long-press your home screen → + → search “Hypna” → add the
Drafts Counter widget. Tap the + and − buttons on the
widget to increment your draft count. When you next open Hypna, those
tallies become actual draft cases for you to finish editing.
Reminders aren’t appearing
1. Make sure iOS notifications are enabled for Hypna: Settings → Hypna → Notifications
2. In Hypna, go to Profile → Reminders and confirm the cadence you want
3. Make sure you’ve granted notification permission when prompted
How do I delete a case or batch of cases?
– Single case: swipe left on the case in the Cases tab, then tap Delete.
– Bulk: in the Cases tab, tap Select (top right), tap cases to select, then tap Delete.
– Whole import batch: Cases tab → Batches → tap the batch → Delete Entire Batch.
What devices does Hypna support?
Hypna requires iPhone running iOS 18 or later.
My state license expiration says “Due Soon” — what does that mean?
Hypna shows three renewal statuses:
– Current: more than 90 days until expiration
– Due soon: within 90 days
– Expired: past the expiration date
Update the expiration date on your Profile page when you renew the license.
