CareBrief Privacy Policy

CareBrief ("Brief," "the app," "we," "our") is built and operated by Kiryl Zhukouski as an independent developer. This policy explains, in plain English, what CareBrief does and does not do with your information.

• All your care notes stay on your iPhone. We do not run a server, we do not have an account system, and we never receive a copy of the things you log about the person you care for.
• No analytics by default. If you opt in, we receive anonymous counts of which screens you used — never any of the content you typed or recorded.
• Apple processes your subscription. We never see your credit card.
• Apple may receive on-device AI inputs. When you tap "Translate," the text is processed by Apple's on-device Foundation Models. It does not leave your iPhone unless your iPhone has Apple Intelligence's Private Cloud Compute enabled and the model decides to use it; in that case Apple's privacy guarantees apply.

If any of the above ever changes, we will update this page and bump the date at the top. Material changes will also surface inside the app.

This policy applies to CareBrief on iOS, distributed through the Apple App Store. It does not apply to:

• Any third-party sites we link to (your hospital's patient portal, Apple's App Store, etc.)
• Anything you choose to share out of CareBrief (e.g., a PDF you email to your doctor — once it leaves the app, this policy no longer governs it)

CareBrief stores the following on your device using Apple's SwiftData framework, in CareBrief's app sandbox:

• The name, date of birth, conditions, allergies, and notes for the person you care for
• Event logs (symptoms, falls, sleep, appetite, mood, vitals, notes) that you create
• Photos you attach to events (Premium)
• Audio transcripts from voice logging (Premium) — the transcript only; the audio recording is never persisted
• Medications and dose history
• Appointments and questions for the doctor
• Optional plain-English summaries you save from the after-visit translator

This data is encrypted at rest by iOS using the same protections that guard the rest of your iPhone. It is not transmitted to us. We have no ability to read or recover it.

By default, nothing. Specifically:

• Subscription purchases. When you start a free trial or purchase Premium, Apple's StoreKit handles the transaction. Apple receives your payment information; we receive only an anonymous "is this device entitled to Premium?" answer. We never see your name, email, card number, or Apple ID.
• Anonymous usage analytics. Off by default. If you turn on "Help improve Brief" in Settings → Privacy, the app sends anonymous counts of which screens you opened and which features you used. It never sends the name of the person you care for, anything you typed or dictated, photos or attachments, health data, or any identifier we can tie back to you. You can turn this off at any time. We retain analytics events for no longer than 12 months.
• Crash diagnostics. iOS's MetricKit framework may send anonymous crash and performance data to Apple, who forwards an aggregated view to us through App Store Connect. These reports do not contain your care notes. You can opt out of this in iOS Settings → Privacy & Security → Analytics & Improvements → Share With App Developers.

When you tap "Translate the visit summary" on an appointment, the text you paste or scan is processed by Apple's on-device Foundation Models framework, which runs the language model on your iPhone's Neural Engine.

• The text does not leave your device unless your iPhone has Apple Intelligence's Private Cloud Compute enabled and the model elects to use it for a particular request. In that case, Apple's privacy guarantees apply: your data is never retained, never used for training, and Apple itself cannot access it.
• We do not log, store, or transmit either your input text or the translator's output. The output appears on screen and is discarded when you leave the screen, unless you tap "Save to appointment notes" — in which case it becomes part of your local appointment record (see §2).
• Suggested follow-up questions become part of your local question list only when you explicitly tap to add them.

Permission	When	Why
Microphone	When you tap Voice on an event	To capture audio for on-device speech recognition. The audio is not recorded or stored.
Speech Recognition	When you tap Voice on an event	To convert your speech to text on-device. Refuses to fall back to Apple's cloud transcription.
Camera	When you tap "Scan" on the visit translator	To photograph a printed after-visit summary for on-device OCR. The image is not saved.
Notifications	First time you set a reminder	To deliver appointment and medication reminders you scheduled.
Health (HealthKit) — Premium, optional	When you enable the import	To read vitals (BP, weight, blood sugar, heart rate, oxygen, temperature) you have authorized. Read-only — we never write to Health.

You can revoke any permission in iOS Settings → Privacy & Security at any time.

CareBrief is rated 4+ and is not directed to children. We do not knowingly collect any personal information from children under 13 (or under 16 in some jurisdictions). The app is intended for use by adult caregivers, who decide what to log about the person in their care.

Because we do not hold a server-side copy of your data, "data subject" requests for access, correction, or deletion are satisfied directly on your device:

• Access: Settings → Data → "Export all data as JSON"
• Correction: edit any record in the app
• Deletion: Settings → Data → "Delete all data" (requires typing the person's name to confirm). This wipes every record and pending notification.

If you opted into anonymous analytics, you can request that we drop any event data tied to your install by emailing the address below with your device's model and the approximate dates of use. Because we do not link events to identifiers, this is a best-effort process.

CareBrief uses the following third-party services to function:

• Apple StoreKit for subscriptions
• Apple MetricKit for crash and performance diagnostics (handled by iOS, not by us directly)
• Apple Foundation Models for on-device translation
• Apple Speech Framework for on-device voice transcription
• Apple HealthKit (Premium, opt-in) for read-only vitals import

We do not currently embed any third-party advertising, marketing, attribution, or social-media SDKs.

Because CareBrief does not transmit your care data, no international transfer of personal data occurs through our use of the app. Apple's own services (StoreKit, MetricKit, Apple Intelligence) are governed by Apple's Privacy Policy.

If we change this policy in a material way, we will:

• Update the effective date at the top of this page.
• Surface a notice the next time you open the app.
• Continue to honor the prior policy for any data already on your device under that policy.

We aim to respond within 7 business days.
