Our Privacy Policy

Forceball Privacy Policy

Published September 23, 2026 · Last updated October 9, 2026

GripFZN Inc. operates Forceball. This policy explains how we handle information collected through the Forceball app, sensor baseball, and related services, as well as through our website and our sales and customer communications.

Information we collect

  • Account and player information: names, email addresses for account holders, organization memberships, and player identifiers and details entered in the app, such as player names and organization associations.

  • Pitching information: grip and session details, notes, timestamps, calibration data, force and pressure measurements, accelerometer and inertial measurement unit (IMU) data, and calculated results.

  • Optional photographs: grip photographs users choose to take or upload.

  • Technical information: device and installation identifiers, hardware and software versions, IP addresses, crash reports, and diagnostic logs, which may include session identifiers.

  • Business contact information: names, job titles, organizations, email addresses, phone numbers, and the content of our communications with prospective and current customers, including messages submitted through our website contact form, email correspondence, and meeting details.

Coaches may provide information about players without accounts. The app stores information locally for offline use and transfers information to our cloud services.

How we use information

We use collected data to operate accounts and organization access, record and analyze pitching sessions, store and synchronize records, provide support, troubleshoot problems, maintain security, and research and improve Forceball.

We use business contact information to respond to inquiries, manage sales and customer relationships, schedule and follow up on meetings, and communicate about our products and services.

We may use anonymized pitching measurements and player attributes to train and evaluate machine-learning models within our own Amazon Web Services (AWS) account. Training datasets exclude player names and teams and are not traceable to individual players.

Access and service providers

Authorized users within an organization can view that organization's player sessions. GripFZN staff or its contractors may access customer information for support and research.

We use the following service providers to process information on our behalf.

Forceball product data

  • Amazon Web Services (AWS) for authentication, hosting, storage, and processing

  • Google Firebase Crashlytics for crash reporting and diagnostics

Sales, customer relationship, and business communications data

  • Attio, our Customer Relationship Management (CRM) platform, to store and manage business contact information, website contact form submissions, email correspondence, and meeting details

  • Google Workspace for business email, calendar, and document storage

  • Notion for internal meeting notes and customer relationship records

  • Slack for internal team communication

Forceball player, athlete, and pitching data is not stored in our Customer Relationship Management (CRM) platform.

Retention and deletion

We currently retain player records, session information, sensor recordings, and uploaded photographs indefinitely, without a scheduled expiration. Archiving or deleting a record in the app removes it from view but does not permanently erase the underlying information. Removing an account or organization does not automatically erase associated records. Backups and older file versions may also retain copies. Technical logs and provider-held diagnostics follow separate retention periods. Business contact information is retained for as long as needed to manage the business relationship.

To request correction or deletion of personal information, contact [email protected]. We may verify your identity and will handle requests in accordance with applicable law.


We plan to add in-app deletion capabilities that will allow authorized users to permanently remove specific records, such as a player who is no longer with the organization, or an entire account or organization, from our production database. Until these capabilities are available, permanent deletion can be requested at [email protected]. Deleted data may remain in backups until those backups expire under our backup retention schedule.

Device permissions

Bluetooth access allows the app to communicate with the Forceball baseball. Camera and photo access support optional grip photographs. You can revoke these permissions in device settings; the corresponding features will then be limited. Revoking permissions or uninstalling the app does not delete information previously uploaded.

Contact and updates

For privacy questions or requests, email [email protected]. We will post updates to this policy and revise its effective date, providing additional notice or obtaining consent where required.
