Privacy Policy

Effective date: July 9, 2026

The individual developer of BulkTrack (the "Operator") handles user information in BulkTrack (the "Service") and on its official website (bulktrack.app, the "Site") as set out below.

1. Information we collect

When you use the app (the Service), we collect:

• Account information: identifiers such as your email address and name obtained through Google or Apple sign-in
• Logged data: information you enter through chat and other features — training, meals, sleep, body weight, and so on — and your conversations with the coach (AI)
• Usage and technical information: device information, push notification tokens, usage logs, and error logs

Through the tester application form on the Site, we collect:

• Email address, nickname, training experience, weekly training frequency, comments, page language, country of access, and browser information (User-Agent)

2. How we use it

• Providing the Service and verifying your identity (sign-in)
• Generating and personalizing coaching (program prescriptions, feedback, and so on)
• Contacting you about TestFlight invitations and screening applications (application form data)
• Improving quality, investigating bugs, and keeping the Service safe
• Sending important notices (push notifications and email)

3. External services and processing

The Service relies on the following external services, and some or all of the information above is sent to them in order to provide the Service.

• Cloudflare (USA): hosting, database, anti-spam (Turnstile), email sending, and part of the AI inference
• Anthropic (USA): generating coach responses. Chat content and aggregated values derived from your logs are sent
• Voyage AI (USA): converting text into vectors for search
• Google / Apple: sign-in and app distribution via TestFlight

Data the Operator sends through these providers' APIs is not used to train AI models, in accordance with each provider's API terms.

4. Sharing with third parties

We do not provide personal information to third parties without your consent, except where required by law (and except for the transfers described above that are necessary to provide the Service). We never share or sell your data for advertising purposes.

5. Cookies and similar technologies

The Site uses one cookie to remember your language preference (lang, kept for one year) and Cloudflare Turnstile for spam protection. We do not use analytics or advertising cookies.

6. Security

Your data is stored separately per account, and communications are encrypted. The Operator takes reasonable security measures to prevent leaks, loss, or damage of information.

7. Retention and deletion

• Logged data is kept for as long as needed to provide the Service. If you would like your account and data deleted, contact us and we will respond within a reasonable period.
• Tester application form data is used only for TestFlight invitations and screening, and is deleted within a reasonable period after recruitment closes.

8. Access and correction requests

You may request disclosure, correction, suspension of use, or deletion of your personal information. Please reach out through the contact page.

9. Changes to this policy

This policy may be revised as needed. For material changes, notice will be given by appropriate means, such as within the Service or on this page.
