Medivoice Privacy Policy

Effective date: August 29, 2026

In short: Medivoice does not collect, transmit, sell, or share any of your personal data. All camera processing, sign recognition, and stored data stay entirely on your device. Medivoice has no user accounts, no analytics, no advertising, and no network connection of any kind.

Who this policy covers

This policy applies to the Medivoice iOS app ("Medivoice", "the app"), developed by Angie Sun ("we", "us"). Medivoice is a communication aid for nonverbal, nonspeaking, and Deaf/hard-of-hearing users, offering a tap-to-speak communication board and an on-device American Sign Language (ASL) sign recognizer.

What data Medivoice accesses

Camera. When you use the ASL Translator feature, Medivoice uses your device's camera to capture live video frames. Each frame is analyzed on-device, in real time, using Apple's Vision framework and an on-device Core ML model to recognize hand and body positions. Frames are processed in memory and discarded immediately — no video or images are ever recorded, saved, or transmitted anywhere.
Accuracy feedback (optional). If you tap "Correct" / "Wrong" after a sign prediction, Medivoice saves that rating (the predicted word, a confidence score, whether it was correct, and a timestamp) to a file stored locally on your device, so the app can show you your own accuracy statistics. This file never leaves your device and contains no video, images, hand landmark data, name, or account identifier.
Test Mode results (optional). A built-in testing tool lets you log recognition accuracy under a name you choose (e.g. a tester nickname) to a CSV file stored locally on your device. This is intended for your own testing/QA use and is only shared if you explicitly use the Files app or the in-app share sheet to send it somewhere yourself.

What Medivoice does not do

No account, sign-in, or personal identifiers are collected.
No data is transmitted to us or to any third party — Medivoice makes no network requests.
No analytics, crash reporting, advertising, or tracking SDKs are included.
No data is sold or shared with third parties, because none is collected off your device.
No cookies (Medivoice is a native app, not a website).

Data storage and deletion

Any data Medivoice creates (accuracy ratings, test CSV files) is stored only in the app's local storage on your device. You can delete it at any time:

Use the "Clear" option in the Recognition Accuracy screen to erase saved feedback ratings.
Delete individual files via the Files app (On My iPhone/iPad → Medivoice).
Deleting the app removes all of its local data permanently.

Children's privacy

Medivoice does not knowingly collect personal information from anyone, including children, because it does not collect personal information from anyone at all. The app is suitable for caregivers to use with patients of any age in a supervised setting.

Health information

Medivoice is a communication aid, not a certified medical interpreter service and not a medical device. It is not intended to diagnose, treat, or replace professional medical or interpretation services. Any words or phrases you speak through the app are generated locally for your own communication purposes and are not recorded or reviewed by us.

Changes to this policy

If this policy changes, we will update the "Effective date" above and post the revised policy at this same URL. Continued use of the app after a change constitutes acceptance of the updated policy.
