Who gets access to the information I share with the app?

PHapp® is designed with your privacy as a top priority. We want you to understand exactly who can access any information you share.

Your Personal Information

You can read alerts in PHapp without an account, and PHapp never asks for your home address. What we hold depends on what you choose to use:

• If you sign up for text alerts, we use your mobile number solely to deliver them.
• If you turn on push notifications in the mobile app without signing in, we store an id for your device, its push token, a label for the device (its name or make and model), a default language setting, and the community whose topics you are subscribed to.
• If you sign in, your Hub Account stores a display name (the name your sign-in provider shares, when it shares one), your email address once it is verified, a link to your profile photo if there is one, which sign-in method you used and when it was last used, plus your settings (such as your community, language, the topics you follow and your notification channels).

Your Location

We do not track your physical location. Alerts are routed by the community you choose, not by where your phone is. The community and topics you follow are stored on our servers as subscriptions linked to your Hub Account, or to your device or phone number if you have not signed in — that is how we know which alerts to send you. You can change them at any time.

Usage Statistics

When you read updates in PHapp, usage is recorded on our servers so agencies can see how far their updates reach:

• These records are not linked to your account, whether or not you are signed in
• Agencies see only aggregated counts, never individual readers
• They are never sold
• If you turn on “Analytics & Improvements” (Settings, under Privacy), your usage is tied to a random ID on your device so we can see how information reaches people over time; it is off unless you turn it on

Alerts and Notifications

The alerts in PHapp come from official agencies and public sources. When PHapp sends you a notification, Hub keeps a record of it on our servers, including its title and text, so it can appear in your notification history.

Messaging Hub Support

Messaging Hub support from inside the app works differently from the rest of PHapp, and we want to be clear about it:

• Authorized staff can read your messages. Authorized Hub support staff can read the messages you send, so they can understand, triage, and reply. Access is limited to authorized staff and is permission-controlled.
• AI drafts the reply, and some replies are sent automatically. We use artificial intelligence to draft a response and to decide when a message needs a person; some replies are sent to you without human review. This runs on Google Cloud’s Vertex AI, inside our own secured environment, under strict contractual data-protection terms that meet healthcare-grade privacy standards. Your message is used only to generate that reply — it is not used to train any AI model, is not retained by the AI service beyond processing, stays in a U.S. region, and is encrypted in transit and at rest.
• We do not log, sell, or share the content. The content of your support messages is not written to our operational logs, analytics, or audit records, and we never sell or share it.
• You stay in control. You can permanently delete your Hub data at any time from PHapp’s Settings, under Account — Delete account if you have signed in, Delete my data if you have not.

Your Rights

You have the right to:

• Know what data is collected (minimal, as described above)
• Opt out of any optional data sharing
• Delete the app and all its data at any time
• Contact support with privacy questions
