Privacy Policy

This policy explains how Discrete Software LLC collects, uses, and shares information when you use the MassMetrics mobile app, MassMetrics Coaching, and related services.

Overview

MassMetrics is operated by Discrete Software LLC. This policy applies when you use the MassMetrics mobile app, use the MassMetrics Coaching web app ("Coaching"), visit our website, contact support, or otherwise use related services.

The mobile app and Coaching use the same account. If you use both, the same account and the information associated with it are used across them.

If you do not agree with this policy, do not use MassMetrics or provide personal information to us.

Information We Collect

MassMetrics may collect account and contact information, such as your name, email address, profile image, login details, support messages, and subscription status.

The app also processes fitness and wellness information that you choose to provide, including workout logs, exercises, sets, reps, weights, macros and nutrition entries, bodyweight records, goals, notes, and related progress data.

If you choose to connect Apple Health or Health Connect, MassMetrics may read and write the steps and weight data you authorize so the app can display, track, and sync your activity and progress. You can manage these permissions in Apple Health or Health Connect on your device.

If you use Coaching, we also collect information about coaching organizations, such as their members, invitations, workout library, and the records coaches keep about athletes.

Account Access

You are responsible for maintaining access to the email address, Apple account, or other login method associated with your MassMetrics account.

For security reasons, we may not be able to restore access, change an account email, or transfer account data unless we can reasonably verify that you control the account.

MassMetrics Coaching

MassMetrics Coaching is a web app that coaches use to work with athletes who use the MassMetrics app. Coaches belong to an organization, and every coach in an organization can see all of its athletes.

Coaches invite athletes by email address, and we send the invitation on the coach's behalf. Joining is your choice: an organization cannot see your data unless you accept its invitation, and you can leave at any time.

Coaches are independent of Discrete Software LLC. Each coach is responsible for how they use the information they can access, including anything they keep outside of MassMetrics.

Sharing with Your Coach

When you join a coaching organization, its coaches can see your name, email address, and profile image, along with the fitness information in your account, such as workouts, nutrition, bodyweight, steps, and goals. This includes information you logged before joining and data imported from Apple Health or Health Connect. Coaches cannot see your password, photos you submit for AI analysis, or your App Store or Google Play subscription details.

Coaches can update your training plan and targets, such as assigning workout programs, editing workout templates, correcting logged workouts, and setting nutrition and step goals. They can also keep notes, check-in records, and payment records about you that only coaches can see. MassMetrics does not process payments between you and your coach.

If you leave or are removed, the organization's access to your data ends immediately. Your account, logged data, and assigned plans stay with you. Records coaches created about you remain with the organization until it is deleted or you delete your account.

Information for Coaches

Invite only people who have agreed to be coached by you, use athlete information only to provide your coaching services, and follow the privacy and health data laws that apply to your business. Other coaches in your organization can see your name, email address, and role.

Organizations pay for Coaching through Polar, our payment provider, which collects payment details directly. We receive the billing contact and subscription details from Polar, but not full card numbers, and we do not share athlete information with Polar.

App, Device, and Website Data

We may collect app diagnostics, crash reports, device information, usage events, and similar technical data to operate, secure, debug, and improve MassMetrics. We configure analytics and diagnostics tools to avoid intentionally sending workout logs, nutrition entries, Apple Health or Health Connect data, or other sensitive fitness information.

When you sign in, we record your IP address and device or browser information with your session to keep your account secure.

Coaching uses cookies and browser storage that are necessary to keep you signed in, secure your session, and remember preferences such as your display theme. Coaching does not use advertising cookies.

Our website may use privacy-respecting analytics to understand aggregate site usage and improve the landing page. These analytics are separate from the fitness information you enter in the app.

Error and Performance Monitoring

We use Sentry, a third-party monitoring service, to detect crashes and errors, diagnose technical problems, and measure and improve the performance and reliability of MassMetrics.

Sentry may process technical information associated with an error or performance event, such as device and operating system details, app version, timestamps, network and performance data, error messages and stack traces, and actions taken in the app shortly before an issue occurred. This information may also include an IP address and an account or user identifier when available.

We configure Sentry to avoid intentionally sending workout logs, nutrition entries, Apple Health or Health Connect data, or other sensitive fitness information. Sentry processes monitoring data on our behalf according to its privacy and data-processing terms.

Marketing Attribution

The mobile app uses AppsFlyer to measure which of our marketing campaigns lead to app installs and subscriptions. AppsFlyer receives device and app information, such as device identifiers, IP address, and install, purchase, and subscription events. We do not send your fitness or health information to AppsFlyer.

You can limit this by turning off personalized ads or resetting your advertising identifier in your device settings.

Apple Health and Health Connect

With your permission, MassMetrics reads your steps and weight from Apple Health on iOS or Health Connect on Android to show your daily activity and weight progress. Entries you log in MassMetrics may be written to the connected health service when you grant write access. Imported entries are stored with your MassMetrics data and synced to your account so your progress is available when you sign in.

You can grant or revoke access to steps and weight separately in Apple Health or Health Connect. Connecting a health service is optional; you can continue to log your steps and weight manually without granting access.

AI-Powered Features

Some MassMetrics features may allow you to submit images or other data for analysis by third-party artificial intelligence service providers. This is a user-initiated action: the data is sent only when you choose to use an AI-powered feature and submit the request.

For example, you can submit a food image for AI-powered nutrition analysis. When you use this feature, the image and instructions necessary to analyze it are transmitted to Discrete Software LLC's servers and then to our third-party artificial intelligence service provider for processing.

Images submitted for AI analysis are used only to generate the requested nutrition estimate and are not intentionally stored by MassMetrics after the request is completed. MassMetrics does not use these images for advertising or marketing, and they are not shared with coaches.

The third-party provider may receive and process the image, data, and related instructions needed to generate a response, according to its own privacy and data-retention terms. You should not submit information that you do not have the right to share or sensitive information that is not needed for your request.

How We Use Information

We use information to provide the app and Coaching, save and display your logs, sync authorized health and fitness data, share athlete information with the coaches of organizations that athletes join, send invitation and account emails, manage accounts and subscriptions, respond to support requests, troubleshoot problems, improve features, prevent abuse, and comply with legal obligations.

We do not sell your personal information.

How We Share Information

If you accept an invitation to join a coaching organization, we share your information with that organization's coaches as described in "Sharing with Your Coach." This sharing happens at your direction and ends when you leave or are removed from the organization.

We may share information with service providers that help us operate MassMetrics, such as hosting, email delivery, analytics, marketing attribution, customer support, security, payment processing, and subscription infrastructure providers. These providers are allowed to use information only to provide services to us.

We may also share information if required by law, to protect the rights and safety of users or Discrete Software LLC, or in connection with a business transaction such as a merger, acquisition, financing, or sale of assets.

Support Communications

If you contact us for support, you may provide personal information, account details, screenshots, diagnostic information, or other context needed to resolve your request.

We may retain support communications to respond to you, improve customer service, investigate issues, and maintain accurate business records.

Processing Location

Information may be processed and stored in the United States and other countries where we or our service providers operate. Privacy laws in those locations may differ from the laws where you live.

Retention

We keep personal information for as long as needed to provide MassMetrics, maintain your account, resolve disputes, comply with legal obligations, and enforce our agreements. Retention periods may vary depending on the type of information and the reason it is stored.

If you delete your account or ask us to delete your information, we will delete or de-identify personal information associated with your account unless we need to keep it for legal, security, fraud-prevention, billing, backup, or legitimate business record purposes.

Your Choices

You can update or delete information in the app where those controls are available. You can change Apple Health or Health Connect permissions on your device. You can manage or cancel paid subscriptions through your Apple account settings or Google Play.

You can accept or decline coaching invitations and leave a coaching organization at any time from the Coaching screen in the app. Organization owners can manage or cancel a coaching subscription from the Billing page in Coaching.

You may contact us at support@discretesoftware.com to request help accessing, correcting, deleting, or exporting personal information associated with your account. If export or account deletion tools are available in the app, you can also use those tools directly. We may need to verify your request before acting on it.

Requesting Account or Data Deletion

To request deletion of your MassMetrics account or personal data, email support@discretesoftware.com.

In your email, include the email address associated with your MassMetrics account and specify whether you want to delete your entire account and its data or only specific personal data. We may need to verify that you control the account before processing your request.

Deleting your account also removes you from any coaching organization and deletes the records coaches kept about you in MassMetrics.

Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.

Children's Privacy

MassMetrics is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, contact us so we can take appropriate action.

Parents and guardians should monitor children's use of apps and online services and should not allow children under 13 to submit personal information through MassMetrics.

US Privacy Rights

Depending on where you live, you may have rights to access, correct, delete, or receive a copy of personal information, or to object to certain processing. To exercise privacy rights, contact Discrete Software LLC at support@discretesoftware.com.

Changes to This Policy

We may update this policy from time to time. If changes are material, we will take reasonable steps to notify you through the app, the website, or another appropriate channel.
