Privacy Policy

When you create an account, we collect:

• Email address and password (password is hashed and stored securely by our authentication provider)
• Name (optional, if you choose to add it)
• Alternatively, you may sign in with Google or Apple, in which case we receive your name and email from that provider
• Date of birth (every user is required to enter their full date of birth during onboarding; access to the App's features is blocked until this check is completed. DOB is stored as part of your account information.)

You may optionally provide:

• Your role (athlete, coach, or parent)
• Your primary event focus (short sprints, long sprints, hurdles, jumps, other)
• Leaderboard opt-in preference

When you use the App’s tools, we may store results in your account history or locally on your device, depending on the tool and whether you choose to save the result.

• Reaction Time Test: reaction times (in milliseconds), false start indicators, and session grouping are saved to your account history.

• CNS Tap Test: tap counts, inter-tap intervals, consistency metrics, fatigue index, readiness scores, and optional caffeine tags are saved to your account history.

• Speed Profile / Performance Predictor: step frequency, step length, velocity, fly zone times, and scenario projections may be saved to your dashboard/history if you choose to save them.

• Wickets Calculator: drill configurations and computed spacings generated from athlete measurements or selected inputs. Certain calculator inputs or preferences may persist locally on your device for convenience, but wicket calculations are not saved to your dashboard/history.

• Block Check: body position angles, checkpoint scores, and other derived measurements from pose analysis are saved to your account history if you choose to save them. Exported images generated from the analysis are saved locally on your device only and are not uploaded to our servers.

• Kinogram Analysis: video frames, stride annotations, comparison data, and generated or exported images may be saved locally on your device if you choose to save them.

  All image and video analysis is performed on your device. We do not upload raw images or videos to our servers in the current version of the App. Only the resulting measurements, metrics, and other saved results described above are stored in your account or App history where applicable. Locally saved images and on-device analysis data are described further in Section 5.

We automatically collect:

• Device information: platform (iOS/Android), screen dimensions, and a truncated user agent string
• Usage events: which tools you open, how long you use them, and session identifiers
• Error reports: crash data and error stack traces (sent to Sentry, our error monitoring service). These do not include personal information beyond your user ID.

We use the information we collect to:

• Provide and maintain the App's features (saving your test results, calculating metrics, displaying your history and trends)
• Display leaderboard rankings (only if you opt in)
• Send you a daily CNS tap test reminder (only if you enable notifications)
• Diagnose and fix bugs via error reports
• Understand how the App is used so we can improve it (aggregate usage analytics)
• Determine whether users meet the minimum age requirement (13+)

We do not:

• Sell your personal information to third parties
• Use your data for advertising or ad targeting
• Share your individual test results with anyone. The public leaderboard, which you must opt in to, shows only your first name and last initial alongside your best-5 average reaction time..

• All user data is stored in a secured Supabase Postgres database with row-level security policies, meaning each user can only access their own data
• Passwords are hashed by Supabase Auth — we never store or see plaintext passwords
• Error reports sent to Sentry are scrubbed of cookies and request headers before transmission
• Authentication sessions are managed by Supabase and persisted on your device so you stay signed in between app launches. Session tokens are access credentials, not passwords, and we never store or see your password.
• Data in transit is encrypted via HTTPS/TLS

The App stores some data locally on your device for performance, convenience, and optional saved media:

• Video analysis metadata and cached speed profile data.

• Block check exported images and related on-device analysis data

• Kinogram frames, annotations, comparison data, and generated/exported images stored locally on your device

• Notification preferences

• Onboarding, UI state flags, and coach guidance dismissals

• Analytics opt-out preference

When you sign out, session state and some cached local data are cleared. Certain locally saved block check and kinogram records may remain on the device, scoped internally to your account so that other users on the same device cannot access them. Reaction test and CNS tap test history is stored with your account and remains available when you sign back in. Those local records are removed when you delete your account or uninstall the App. A small number of device-scoped items (such as the App Store review prompt state and open count, and CNS reminder preferences) persist across sign-outs so that we don't repeatedly prompt the same device.

We retain your data only as long as necessary for the purposes described in this policy:

• Account information, profile, and test results: retained until you delete your account. When you delete your account, all associated records are permanently removed from our servers.
• Analytics events (usage data, session identifiers): retained while your account is active and deleted when you delete your account.
• Error reports (crash data, stack traces): managed according to Sentry's retention policy.
• Transactional email logs (verification codes, password resets): managed according to Resend's retention policy.
• Authentication and security logs: managed by Supabase according to its platform defaults.
• On-device data (IndexedDB, local storage): some data is cleared on sign-out, while some remains on your device until you delete your account or uninstall the App, with the limited exceptions noted in Section 5.

Anonymized, aggregated data that cannot identify you may be retained for product improvement purposes. We may also retain limited records as required by law or to prevent fraud.
