Privacy & Data Use

Continuum — Hockey TBI Risk Calculator. Effective July 10, 2026.

Plain summary: This tool lets you record a hockey head-impact history and current symptoms so you can discuss them with a doctor. If you create an account, that information is stored securely so you can track it over time. We never sell or share it, and you can delete everything yourself at any time. This is not a medical device and not a diagnosis.

Who we are

This app is provided by Continuum Improvement LLC (“we”). Contact: support@continuumimprovement.com.

What we collect

Account: your email address and a securely hashed password. We never see or store your actual password.
Head-impact history: the hockey details you enter (seasons played, highest level, position, practice-contact level, diagnosed concussions, age first played).
Symptom data: your answers to the symptom screen.

If you use the app without an account, your information stays on your device and is not sent to us.

Why we collect it

Only to provide the tool: to let you save the record, return to it over time, and produce a one-page summary to bring to a doctor. We do not use it for advertising.

How it is stored and protected

Account and saved data are stored with our backend provider (Supabase) using encryption in transit and at rest, with access controls so that only you can access your own records.

Sharing

We do not sell, rent, or share your personal information. We use a service provider (Supabase) solely to store your data on our behalf. We may disclose information only if required by law.

Your choices and rights

Access: your data is shown to you in the app whenever you are signed in.
Delete: you can permanently delete your account and all associated data at any time inside the app. This is immediate and cannot be undone.
Use without an account: you can use the tool locally without registering.

Data retention

We keep your saved data until you delete it or your account.

Children’s privacy

This app is intended for adults 18 and older. It is designed to be used by an adult former player, or by a parent or legal guardian recording information about a minor athlete in their care — not by children directly. Children should not create accounts or use the app themselves. We do not knowingly collect personal information directly from a child under 13. When a parent or guardian records a minor athlete’s information, they do so as the adult account holder, are responsible for that information, and can view or permanently delete it at any time inside the app. If we learn we have collected personal information directly from a child under 13 without a parent or guardian, we will delete it. We never sell a child’s information or use it for advertising. To review or delete a minor’s information, contact support@continuumimprovement.com.

Not medical advice

This app documents self-reported head-impact history and symptoms to support a conversation with a clinician. It is not a medical device, does not diagnose, and cannot tell you whether a brain injury or CTE is present. CTE can only be diagnosed after death. If you or someone you are helping is in crisis, call or text 988 (Suicide & Crisis Lifeline), 24/7.

Changes

If we change this policy we will update the date above.
