1. Introduction

Harmony is an AI-powered relationship app for individuals and couples, operated by MS Global Holdings LLC ("we", "us"). This Privacy Policy explains what we collect, how we use it, who processes it on our behalf, and the rights you have over your data. By using Harmony you agree to the practices described here. For privacy requests or questions, contact privacy@talkharmony.app.

2. Information We Collect

We collect only what we need to run the app. Categories include:

Account information: name, email address, account identifier from Apple or Google when you use those sign-in methods, and an in-app display handle. We never store passwords; sign-in is passwordless (one-time email code, Apple, or Google).
Profile signals: birthday, optional anniversary, optional birth location, partner relationship status, and quiz answers used to compute your love language, attachment style, and conflict style.
Session data: chat transcripts and voice recordings from solo and couples coaching sessions, AI-generated session titles, mood emoji, one-line summaries, and harmony scores. Voice sessions are streamed to our voice provider for real-time response and are not stored as audio after the session ends.
Journal data: journal entries you write or dictate, AI-generated insights and one-sentence summaries, optional partner-share flag.
Mood and goal data: mood check-ins, post-session moods, relationship goals, goal progress logs.
Partnership data: partner connection identifiers, days connected, sessions together, entries shared.
Device data: Apple Push Notification Service (APNs) device tokens, app version, iOS version, device model. Used only to deliver notifications and diagnose crashes.
Usage data: anonymous interaction signals (which features you open, session lengths) used to improve the app. We do not collect precise location, advertising identifiers, or contacts.

3. How We Use Your Information

To provide AI coaching during solo and couples sessions and to translate tense couples messages before they reach your partner.
To generate personalized insights, session summaries, journal reflections, and your Connection Score.
To deliver session invites, partner activity, and reminder notifications.
To detect and respond to crisis-language patterns (see Section 7).
To process subscription billing through Apple.
To diagnose bugs and improve the product.

4. AI Processing and Training

Harmony sends portions of your messages, journal entries, and voice audio to AI providers (currently Anthropic and Google) to generate responses, summaries, and insights. These providers are bound by contracts that prohibit using your data to train their models. Data sent for AI processing is retained by the provider only long enough to return the response. We do not sell your data to anyone, and we do not use your conversations to train any model ourselves.

5. Subprocessors

We rely on a small set of third-party subprocessors to operate the service. The current list, including the role each one plays, is published at talkharmony.app/subprocessors. The major ones are: Anthropic (language models), Google (Gemini voice and language models), Supabase (database, authentication, edge functions), Apple (Sign in with Apple, App Store billing, APNs), Sign in with Google (optional auth), PostHog (product analytics, error tracking, and session replay — sensitive views such as journal entries and partner chat are masked before recording), AppsFlyer (install attribution for paid advertising — we use this only to measure which ad campaign brought you here; the App Tracking Transparency prompt asks for your consent before sharing your device's advertising identifier), and Vercel (marketing site hosting). Live transcription for journal dictation runs on-device using Apple Neural Engine acceleration when available.

6. Authentication

Harmony supports three sign-in options: Sign in with Apple, Sign in with Google, and a passwordless one-time code sent to your email. We do not store passwords. When you use Apple or Google sign-in, we receive a limited set of profile information (name, email address, account identifier) only to create and identify your Harmony account.

We do not request access to any other Google data (such as Gmail, Drive, Calendar, or Contacts), and we do not share, sell, or transfer the data we receive from Google to third parties for any purpose other than what is strictly necessary to provide the Harmony service. You can revoke Harmony's access to your Google Account at any time at myaccount.google.com/permissions.

Harmony's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Apple sign-in is governed by Apple's privacy practices.

7. Crisis Safety

Harmony runs deterministic, on-server pattern matching for self-harm and crisis language alongside the AI safety layer. When a message matches, we surface 988 (Suicide & Crisis Lifeline) and 741741 (Crisis Text Line) inline and prevent the message from being broadcast to a partner during couples sessions. We retain these matches as part of the session record so the AI can recognize patterns across sessions; we do not share crisis flags with third parties beyond the subprocessors listed in Section 5. Harmony is not a substitute for professional care. If you or someone you know is in danger, call or text 988, or call 911.

8. Couples and Shared Data

When you pair with a partner, certain data becomes visible to them: couples-session transcripts, journal entries you have explicitly marked as shared, your Connection Score, mood entries you have toggled to share, and shared goals. Solo sessions, private journal entries, and unshared moods remain visible only to you. If you unpair, both devices stop seeing newly-created shared data, and shared rows created during the partnership remain authored by their original writer; cross-partner visibility ends.

9. Data Security

Conversations and journal entries are encrypted at rest and in transit. We use platform-grade authentication (Apple, Google, or one-time email code), row-level security policies on the database, and signed URLs for any media. No system is perfectly secure; if we ever discover a breach affecting your account, we will notify you and any required regulators.

10. Data Retention and Deletion

We keep your account data for as long as your account is active. You can delete an individual journal entry, session, mood, or goal at any time from inside the app. To delete your entire account and all associated data, open Profile, Privacy & Security, Delete Account; the deletion is processed within 30 days. You can also email privacy@talkharmony.app to request a deletion or an export of your data.

11. Children

Harmony is not intended for users under the age of 13. We do not knowingly collect data from children under 13. If we learn that we have, we will delete the account and the associated data.

12. International Users

Harmony is operated from the United States. If you use the app from outside the U.S., your data will be transferred to and processed in the U.S. (and any other country where our subprocessors operate). Where required, we rely on Standard Contractual Clauses or equivalent transfer mechanisms.

13. Your Privacy Rights

Depending on where you live, you may have the right to access, correct, delete, or port your data, and to object to or restrict processing. You can exercise most of these directly in the app. For anything else, contact privacy@talkharmony.app and we will respond within 30 days.

14. Changes to This Policy

We may update this policy as the product changes. When we make a material change, we will update the "Last updated" date at the top and, where appropriate, notify you in-app or by email.
