Privacy Policy

1. Who We Are

The data controller responsible for your information is FourMeasure, Inc., 500 Oleander Drive, Hallandale Beach, FL 33009. For any privacy question or request, contact support@fourmeasure.com.

2. Information You Provide

• Account information: an email address or phone number, and a password. If you sign up with a phone number, we create an internal account identifier from it.
• Profile information: username, display name, bio, profile photo/avatar, your "top items" (favorite songs/albums), and your favorite genres.
• Date of birth (to confirm you meet our minimum age and for age-appropriate features).
• Content you create: posts, reviews, ratings, comments, reactions, and the contents of direct messages (including any images or media you attach).
• Reports and communications: reports you submit about content or users, and messages you send to support.

3. Information We Collect Automatically

• Device and instance identifiers: a Firebase Cloud Messaging push token (to deliver notifications) and a first-party Firebase analytics app-instance identifier, each associated with your account. We do not collect advertising identifiers (Apple's IDFA or Android's Advertising ID).
• Log and usage data: IP address, device/user-agent information, timestamps, and actions taken in the app (e.g., posts viewed, features used).
• Approximate location (no GPS): we do not collect precise or GPS location, and the app does not request location permission. Our analytics provider (Google/Firebase) derives an approximate location (such as country or city) from your IP address for analytics. We also use and retain your IP address to secure your account, manage your active sessions, and help prevent fraud.
• Analytics and diagnostics (mobile SDKs):
  • Firebase Analytics (Google) — a fixed set of product-interaction events (such as sign-up, login, post created, follow) keyed to your internal account identifier, not your name, email, or phone.
  • Firebase Crashlytics (Google) and Sentry — crash and error diagnostics (stack traces and device state) tied to your internal account identifier.
• No advertising or cross-app tracking: the app contains no advertising or attribution SDKs, does not display ads, does not present Apple's App Tracking Transparency prompt, and does not track you across other companies' apps or websites.

4. Information From Third Parties

• Single sign-on: if you sign in with Google or Apple, we receive basic profile information from them (such as your email, name, and avatar) per your settings with that provider.
• Connected music providers: if you connect a music account (e.g., Spotify, Apple Music), we receive information needed to provide the integration, which may include your now-playing/listening activity (when you enable that feature) and access tokens. We store provider access and refresh tokens encrypted and use them only to provide the features you enabled.
• Phone verification: when you verify a phone number, our verification provider (Firebase Phone Authentication) confirms the number to us.

5. How We Use Information

We use information to: create and secure your account; provide and personalize the Service (feeds, profiles, recommendations, messaging); deliver notifications; enable features you turn on (such as music-provider integrations); maintain safety and integrity (moderation, abuse prevention, enforcing our Community Guidelines); analyze and improve the Service; communicate with you about the Service; and comply with legal obligations. Where required by law, we rely on legal bases including performance of our contract with you, your consent (which you may withdraw), our legitimate interests (such as security and improving the Service), and compliance with legal obligations.

6. How We Share Information

We do not sell your personal information for money, and we do not share it for cross-context behavioral advertising. We share information only as follows:

• With other users: your profile and the content you choose to share are visible to others according to your settings. If your account is private, your content is limited to approved followers. Direct messages are visible to participants in the conversation.
• Service providers (sub-processors) who process data on our behalf under contract:
  • Amazon Web Services (AWS) — cloud hosting, file/media storage (S3), and transactional email (SES).
  • Google / Firebase — push notifications (FCM), phone-number verification (Phone Authentication / SMS), product analytics (Firebase Analytics), and crash diagnostics (Firebase Crashlytics).
  • Sentry — crash and error monitoring/diagnostics.
  • Spotify and Apple Music — only if you connect those accounts.
  • Giphy — GIF search within comments and messages.
  • Musixmatch — music metadata.
• For legal and safety reasons: to comply with law or valid legal process, enforce our Terms, or protect the rights, safety, and security of users, the public, or Four Measure.
• Business transfers: in connection with a merger, acquisition, financing, or sale of assets, subject to this Policy.

7. Your Choices and Rights

• Access, update, and delete: you can view and edit your profile in the app, and you can delete your account at any time from the app, which removes your account and associated personal data (subject to limited retention described below).
• Notifications: you can control push notifications in your device and app settings.
• Connected accounts: you can disconnect a music provider at any time.
• Privacy (GDPR/EEA/UK): if you are in the European Economic Area or the UK, you have rights to access, rectify, erase, restrict, or object to processing of your personal data, to data portability, and to withdraw consent. You may also lodge a complaint with your local supervisory authority.
• Privacy (California/US state laws): if you are a California resident (or in a U.S. state with similar laws), you have rights to know, access, correct, and delete your personal information, and to not be discriminated against for exercising them. Because we do not sell or "share" personal information for advertising, no opt-out of sale/sharing is needed.

To exercise any right, contact support@fourmeasure.com. We will verify your request and respond as required by law. You may use an authorized agent where permitted.

8. Data Retention

We keep personal information for as long as your account is active or as needed to provide the Service, and afterward only as necessary to comply with legal obligations, resolve disputes, enforce our agreements, and for reasonable backup/security purposes. When you delete your account, we delete or de-identify your personal data within 30 days, except where a longer retention period is legally required. Security and server logs (such as IP addresses) are retained for up to 90 days and then automatically deleted.

9. How We Protect Information

We use technical and organizational measures to protect your information, including encryption in transit, hashing of passwords, and encryption at rest for sensitive items such as connected music-provider tokens. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.

10. Children's Privacy

The Service is for users 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us personal information, contact support@fourmeasure.com and we will take steps to delete it. If you are between 13 and the age of majority where you live, use the Service only with a parent or guardian's consent.

11. International Data Transfers

We operate primarily in the United States, and your information may be processed in the United States and other countries that may have different data-protection laws than your own. Where required, we use appropriate safeguards (such as Standard Contractual Clauses) for cross-border transfers.

12. Third-Party Links and Services

The Service may link to or integrate third-party services. Their use of your information is governed by their own privacy policies, not this one. Review the privacy policies of any music provider or other service you connect.

13. Changes to This Policy

We may update this Policy from time to time. If we make material changes, we will provide notice (for example, in the app) and update the "Last updated" date. Your continued use of the Service after changes take effect constitutes acceptance.
