Privacy Policy

Last updated: June 26, 2026

ProtocolGT (“we,” “us,” or “our”) operates the ProtocolGT mobile application (the “App”). This Privacy Policy explains how we collect, use, store, and protect user data.

By using the App, you agree to the collection and use of information in accordance with this policy.

 

 

1. Information We Collect

We collect the following types of data when you use the App:

a. Personally Identifiable Information (PII)

  • Email address

  • First Name (optionally)

  • Phone Number (optionally)

  • Birthdate (optionally)

  • User identifiers (such as a unique user ID associated with your account)

This information is used to create and manage your account and enable core app functionality.  We do not share or sell any PII with any third-parties. Users can optionally join a leaderboard where their name is viewable by any app user. Our development and business team may view PII about users for troubleshooting and app development. Users can toggle whether they would like to receive marketing emails about Protocol Grip Trainer when they enter their email. If users choose to receive marketing emails, they can click the unsubscribe link at the bottom of any email to stop receiving marketing emails from us. We will not allow any third party to send you marketing emails.

b. Demographic information

  • Age (optionally)

  • Gender (optionally)

If birthdate and gender are optionally entered, we use them to calculate users’ grip strength percentiles. We do not share or sell any demographic information with third parties, but if a user chooses to join a shared party, others could be able to view the user’s age group (10-year age range) and gender. We also may use age and gender to personalize our notifications and marketing emails. We use age and gender for business analytics and troubleshooting.

c. Fitness and Activity Data

  • User-provided or app-generated fitness-related data (such as grip strength measurements, workout metrics, or other training-related information)

Fitness data is associated with your account to provide personalized functionality and progress tracking.

d. Ephemeral data

  • Bluetooth connections

  • Location 

  • Payment information


This information is never stored - neither on your device nor on a server. Our app may use this data to make payments and interact with physical Bluetooth devices.

 

 

2. How We Use Your Information

We use the collected data for the following purposes:

  • Account creation and authentication

  • Providing app functionality

  • Analytics

  • App development and troubleshooting

  • Making payments

  • Research and development (see Section 4)

 

 

3. Data Storage and Security

User data is securely stored using cloud infrastructure provided by Amazon Web Services (AWS), including:

  • Amazon Cognito (authentication and identity management)

  • Amazon DynamoDB (structured data storage)

  • Amazon S3 (file storage)

All data:

  • Is encrypted in transit using TLS

  • Is encrypted at rest using AWS-managed encryption

AWS acts solely as a data processor on our behalf and does not use your data for its own purposes.

We also use Google Analytics to analyze how users respond to our app. We store fitness, click, and demographic data in Google Analytics. We do not store any PII on Google Analytics. We do not sell your data or engage in targeted advertising.

We use Sentry for debugging and analytics.

 

 

4. Research Use

We may use fitness data to:

  • Build datasets

  • Support research and product improvement

  • Share these datasets after removing any links to PII

Before being used for these purposes:

  • Personally identifiable information including email addresses, names, and phone numbers are removed,

  • We may use randomly generated user identifiers to associate a user’s workouts with each other.

  • We may associate the fitness data with demographic data (age and gender).

  • On requesting account deletion, any internal associations between personally identifiable information and the user identifiers will be deleted.

Fitness data may be retained indefinitely for research purposes.

 

 

5. Data Sharing

We do not sell any personally identifiable information to any third-party. Users may choose to allow us to share their first name, age group, and gender with other users by joining a shared party. 

PII data is only accessed by:

  • Application services

  • Our team for analysis and development

  • Authorized service providers acting on our behalf (AWS, Google Analytics, and Sentry)

  • The first name, age group, and gender are optionally viewable by other app users.

Demographic data is not sold to any third-party. We may use demographic data for:

  • Research

  • Analytics

  • App Functionality

If the user chooses to join a leaderboard, others might be able to deduce the user’s age group and gender by reversing our grip percentile calculation.

 

 

6. Messaging


 

 

6. Data Retention

We retain personal data only as long as necessary to:

  • Provide the App’s services

  • Comply with legal obligations

Anonymized data may be retained for research and analytics purposes.

 

 

7. Account Deletion and Data Removal

Users may request deletion of their account and all associated personal data by pressing the ‘Delete Account’ button within the app or by contacting us at:

Email: wayne@protocolgriptrainer.com
(or via the account deletion link provided in the app or on our website)

Upon request:

  • Your account will be deleted

  • Associated personal data will be removed

 

 

8. Children’s Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal data from children.
