MCO TWU 555 (“the App”) is designed to provide users with convenient access to union-related resources, documents, tools, contact information, updates, and other information relevant to TWU Local 555 members at MCO.
The App does not require users to create an account or provide personal information simply to access its primary informational features.
Certain optional features may direct users to third-party services, forms, websites, or other resources. Information voluntarily submitted through those services is subject to the privacy practices of the applicable third-party service.
If you choose to submit App Feedback, we collect the subject and description you enter, any name or employee number you choose to provide, and the app version and device operating system attached to the report. Reports are processed using Google Apps Script and Google Sheets to answer feedback, troubleshoot issues, and improve the App. Please do not include passwords, medical information, or other sensitive personal information in feedback.
The Android messaging service may automatically generate a Firebase installation identifier to operate its messaging infrastructure. If you enable union push notifications, the App also registers a push token, a random app installation identifier, an anonymous authentication identifier, your device platform, and your selected notification categories with our notification backend. These identifiers support device registration, authentication, delivery, and honoring your preferences; a member login is not required.
The App does not sell users' personal information.
Union push notifications are optional. You can enable them, select alert categories, or turn off push delivery from More > Notification Preferences. System notification permission is controlled in your device settings.
Turning off push delivery or a category excludes this device from future union messages after the server receives the change. Offline changes are saved and retried when the App reconnects; delivery may continue until the server confirms the change. Messages already handed to a platform provider cannot be recalled. Device notification settings can block display immediately.
The App contains links to external resources and services. These may include union resources, forms, document services, workplace resources, and other websites.
When users leave the App or interact with a third-party service, that service's own privacy policy and data practices may apply. MCO TWU 555 is not responsible for the privacy practices of third-party websites or services.
The App does not sell or rent personal information to advertisers.
We use service providers to process data on our behalf: Supabase for notification registration, authentication, and storage; Expo and Google Firebase Cloud Messaging for Android notification delivery; Apple Push Notification service for iOS delivery; and Google Apps Script and Google Sheets for submitted feedback. These services also have their own privacy and security information.
The App uses encrypted HTTPS connections for notification registration and feedback submission. Push tokens are encrypted when stored in the notification backend. Access to union notification sending is limited to authorized administrators. No electronic transmission or storage method can be guaranteed to be completely secure.
Data Retention and Deletion Requests
Registration and preference records are retained as needed to provide notifications, honor opt-outs, and protect registration integrity. Feedback records are retained as needed to review and resolve reports and maintain the App. To request access to or deletion of information you provided, email Gadcontreras5@gmail.com and describe the relevant submission or device registration. We may request information needed to identify the record and verify the request. Turning off push delivery does not automatically delete previously submitted feedback.
The App is intended as a workplace and union-resource application and is not directed toward children under 13.
This Privacy Policy may be updated as the App's functionality changes. Updates will be reflected on the publicly available version of this policy.
