Privacy Policy

Last updated: 26 April 2026

TurboPrep is a training app for high-school Human Powered Vehicle (HPR) athletes preparing for the Victorian HPR Series. This policy explains what data we collect, why, and how you can control it.

Plain-English summary: we collect what we need to give you training plans, team leaderboards, race-day tracking and AI coaching. We never sell your data. You can delete your account at any time.

Who we are

TurboPrep is operated by TDOG Industries. Day-to-day support is handled by Tenny Hearn. Contact: hearn.tenny@icloud.com.

Third parties

We use the following services to run TurboPrep. Each handles data only for the purpose described.

Google Firebase (auth, database, hosting) — stores your account and training data. Firebase privacy
Apple HealthKit — read-only access to health data on your device, with your explicit permission

Children & minors

TurboPrep is designed for high-school athletes Years 7-12, which includes users aged 12 and over. We comply with the Australian Privacy Principles and Apple's app rules for apps used by minors.

We do not show third-party advertising
We do not sell or trade personal data
Year 7 athletes (typically aged 12-13) should sign up with a parent or guardian's involvement — most schools coordinate this through the HPR team
Coaches and parents (with athlete consent) can view athlete progress; athletes control what they share

If you believe a child under 13 has signed up without appropriate consent, email hearn.tenny@icloud.com and we will delete the account.

Data security

Account data is stored in Google Firebase (Australia / global Google datacenters) and protected by Firebase Security Rules so other users can't read your private records. Authentication uses standard Firebase Auth. We use HTTPS for every request.

No system is perfectly secure. If we ever suffer a data breach affecting you, we will notify you within 72 hours.

TurboPrep is operated from Australia. Data may be processed in Google's global datacenters (commonly the United States) and Anthropic's processing region (United States). By using TurboPrep you consent to this transfer.
