Privacy Policy

Effective date: June 1, 2026

This Privacy Policy describes how Hundo ("we," "our," or "us") collects, uses, and shares information when you use https://hundotracker.com (the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.

1. Information we collect

Account information

When you create an account, we collect your email address and a password (stored as a secure hash). If you sign in with Google, we receive your email address and Google profile name from Google's OAuth service. We store a display name derived from your email address.

Waitlist information

If you join our waitlist before launch, we collect your email address and the page source where you signed up. This information is used only to notify you when the Service goes live.

Usage and progress data

When you use the tracker, we store which items you have marked as completed, along with timestamps. If you are a premium subscriber, we also store private notes you attach to items. This data is associated with your user account.

Automatically collected information

Like most web services, we collect standard server log information including your IP address, browser type, pages visited, and referring URLs. This information is used to operate and improve the Service.

2. Cookies and advertising

Hundo uses Google AdSense to display advertisements. Google AdSense uses cookies and similar tracking technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out through the Network Advertising Initiative opt-out page.

We also use cookies necessary to operate the Service — specifically, session cookies managed by Supabase for authentication. These cookies expire when you sign out or close your browser session.

3. How we use your information

  • To provide, maintain, and improve the Service
  • To authenticate your account and protect its security
  • To sync your completion progress across devices
  • To display your progress on the leaderboard (if you have opted in)
  • To send launch and product notifications (waitlist email only — no marketing without consent)
  • To process payments for premium subscriptions via Stripe
  • To comply with applicable law

4. Third-party services

We use the following third-party services that may collect and process data on our behalf:

  • Supabase— database, authentication, and file storage. Your account credentials and progress data are stored on Supabase infrastructure. Supabase's privacy policy is available at supabase.com/privacy.
  • Google OAuth and AdSense— Google provides optional sign-in and delivers advertisements on the Service. Google's privacy policy is available at policies.google.com/privacy.
  • Stripe— payment processing for premium subscriptions. We do not store your full payment card details. Stripe's privacy policy is available at stripe.com/privacy.
  • Resend— transactional email delivery for account confirmations and waitlist notifications. Resend's privacy policy is available at resend.com/legal/privacy-policy.

5. Data sharing

We do not sell your personal information. We do not share your email address or account information with third parties except as described in this policy (i.e., with infrastructure providers who process data on our behalf) or as required by law.

Your display name and completion percentage are publicly visible on the leaderboard if you have opted into leaderboard participation. You can opt out at any time from your account settings.

6. Data retention and deletion

We retain your account data as long as your account is active. If you delete your account, your personal information and completion data are permanently deleted within 30 days. Waitlist entries are deleted after launch notifications are sent.

To request account deletion or a copy of your data, email us at hello@hundotracker.com.

7. Security

We use industry-standard security measures including encrypted data transmission (HTTPS), hashed password storage, and row-level security policies in our database. No method of transmission or storage is 100% secure. If you believe your account has been compromised, contact us immediately.

8. Children's privacy

The Service is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us and we will delete it promptly.

9. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will update the effective date at the top of this page. Continued use of the Service after changes are posted constitutes your acceptance of the updated policy.
