Propagate Privacy Policy

Effective date: June 18, 2026

Who we are and what this covers

Propagate is a free iOS app made by Softwear Technologies, Inc. (“we”, “us”). It gives injured runners AI-powered rehab coaching: you chat with an AI coach, it identifies a likely injury, assigns exercise tracks, and tracks your daily completion.

This policy covers the Propagate iOS app and the backend services that power it. Questions? Email ryan@propagateform.com.

What we collect

  • Account information. Propagate requires sign-in with Apple or Google (through Firebase Authentication). When you sign in we receive your name, your email address, and a persistent account identifier (a Firebase user ID).

  • Coach conversations. The full transcript of your chats with the AI coach, including anything you tell it about your injury, pain, and symptoms.

  • Your rehab plan and profile. Your goal, the coach’s assessment of your likely injury, and the coach’s notes about you.

  • Daily exercise records. Which exercises you completed each day, including outcomes such as “Too Painful.”

Because Propagate is about injuries and pain, much of this is health and fitness information linked to your identity. We treat it accordingly — see “Health information” below.

How we use your data

We use your data for exactly one purpose: making the app work for you.

  • Your chat messages and a summary of your profile are sent to the AI so the coach can respond.

  • Your plan and daily records are stored so the app can show your progress and adjust your exercises.

  • Your account information is used to sign you in and keep your data tied to your account.

Where your data lives

Your data is stored in two places:

  • On your device, in the app’s local files.

  • In Google Firebase Firestore (Google Cloud), in a record tied to your account ID, so your plan and history survive reinstalls and device changes.

AI processing and third parties

We share your data with two service providers, and only so the app can function:

Google Firebase / Google Cloud. Provides sign-in (Firebase Authentication), cloud data storage (Firestore), and the backend functions that relay your messages to the AI.

Anthropic PBC. The AI coach is powered by Claude, Anthropic’s AI model. When you chat with the coach, your messages and a summary of your rehab profile are sent through our backend (Google Cloud Functions) to Anthropic’s API. The API key is held on our servers, never on your device. Anthropic processes this data under its standard commercial API terms: your data is not used to train Anthropic’s models, is retained briefly for trust and safety purposes, and is then deleted.

The app tells you this up front: an in-app disclosure explains that the coach is an AI, that your messages are processed by Claude (Anthropic) and stored in your Propagate account, that AI can make mistakes, and that it is not medical advice.

We do not share your data with anyone else.

Health information notice

Propagate handles information about your injuries, pain, and symptoms, but Propagate is not medical advice and we are not a healthcare provider:

  • We are not a covered healthcare provider, and Propagate is not a medical device.

  • Using Propagate does not create a provider–patient relationship.

  • The coach’s suggestions are general informational content, not professional medical advice, diagnosis, or treatment.

If you have severe pain, numbness, or a suspected fracture, consult a clinician. In an emergency, call 911.

How long we keep your data

We keep your data for as long as you have an account. When you delete your account, your data is promptly deleted.

Deleting your data and your rights

You can delete your account at any time, directly in the app: open the More tab and tap Delete Account. This:

  • removes your cloud data (chats, plan, records),

  • deletes the Propagate sign-in account itself, and

  • clears the app’s local files on your device.

No email required, no waiting on support. If you have questions or want to exercise other privacy rights available to you under your local law (such as access or correction), email ryan@propagateform.com

Security

  • All communication between the app, our backend, and our providers uses HTTPS encryption.

  • Per-user Firestore security rules ensure only your signed-in account can read your data.

  • The AI provider API key is held server-side and is never present on your device.

No system is perfectly secure, but we limit what we collect to what the app needs to function.

Children

Propagate is not directed at children under 13, and we do not knowingly collect data from children under 13. The app’s App Store age rating is 12+. If you believe a child under 13 has created an account, contact us and we will investigate it.

International transfers

Your data is processed in the United States, on Google Cloud and Anthropic infrastructure located in the US. If you use Propagate from outside the US, your data will be transferred to and processed in the US.

Changes and contact

If we change this policy, we will update the effective date above and, for significant changes, notify you in the app. Continued use after a change means you accept the updated policy.
