Introduction
SignPrep (“the app”) is developed by Daniel Yong. This privacy policy explains how the app handles your information. The short version: your data stays on your device, and we do not collect, store, or share any personal information.
Data collection
SignPrep does not collect, transmit, or store any personal data on external servers. The app does not use analytics services, advertising frameworks, crash reporting tools, or any third-party SDKs that collect user data.
On-device data
All data you create within SignPrep is stored locally on your device using Apple's standard on-device storage frameworks. This includes:
- Calendar assignments imported via EventKit
- Glossary entries (videos, labels, descriptions, and notes)
- DC-S reflection logs
- Mood and self-care check-in records
- App settings and preferences
This data is not accessible to the developer or any third party. Deleting the app removes all stored data permanently.
iCloud and device backups
SignPrep stores its data locally on your device. If you have iCloud Backup, or a Finder/iTunes backup, enabled, that local data may be included in your own encrypted device backup — the same as for any other app on your device. This backup is created and controlled entirely by you through Apple, stays within your Apple account, and SignPrep has no server and no access to it.
If you handle sensitive assignment details and prefer to keep them out of any backup, the most reliable approach is to keep patient or client identifiers out of the app and your calendar in the first place — SignPrep is designed to work from the job type, not from personal details. SignPrep also includes an in-app option to exclude its data from device backups, so you can keep it out of iCloud and Finder/iTunes backups entirely if you prefer.
App Lock
SignPrep offers an optional App Lock that uses Face ID or Touch ID to keep the app private when your device is unlocked. Biometric authentication is handled entirely by Apple’s on-device system — your face or fingerprint data is never seen by, shared with, or stored by SignPrep. When App Lock is enabled, the app also hides its contents in the app switcher.
Calendar access
SignPrep requests read-only access to your device calendars through Apple EventKit in order to display upcoming interpreting assignments. Calendar data is read locally and is never transmitted outside your device. You can revoke calendar access at any time in your device's Settings › Privacy & Security › Calendars.
Camera and microphone access
The app requests camera and microphone access solely to record sign language videos for your personal glossary. Video recordings are stored locally on your device and are never uploaded or shared with any server.
Notifications
SignPrep may request permission to send local notifications to remind you about upcoming assignments. Notifications are generated and scheduled entirely on your device. No push notification servers are used.
AI features
SignPrep uses Apple's on-device Foundation Models for AI-powered features such as research prompts, glossary word suggestions, and self-care recommendations. All AI processing happens locally on your device. No prompts, inputs, or outputs are transmitted to external servers.
Third-party services
SignPrep does not integrate with any third-party services, APIs, or servers. The app does not contain advertising. The app does not use cookies or tracking technologies.
Data sharing
SignPrep does not share any data with third parties. There is no data to share because no data is collected.
Children's privacy
SignPrep is not directed at children under the age of 13. The app does not knowingly collect information from children.
