Privacy Policy

1. Who we are

Heater is a blackjack card counting application for iOS and Android, operated as an independent project. References to "we," "us," and "Heater" refer to the app and its operators.

2. Information we collect

Account information

When you create an account, we collect:

• Email address (used for sign-in and account recovery)
• Password (stored securely, hashed by our authentication provider)
• Account creation date

Usage data

To enforce daily free-tier limits and provide session history, we store:

• Number of cards counted per day (per user account or device identifier for anonymous users)
• Session records, when you choose to save them: start time, duration, number of shoes played, peak true count, optional win/loss amount, optional notes
• Your bankroll and deck preference settings

Device information

For anonymous (non-signed-in) users, we use a device identifier provided by your operating system to enforce daily limits. This identifier is not linked to any personal information and cannot be used to identify you outside the app.

Subscription and payment information

Subscription purchases are processed by Apple App Store or Google Play. We do not collect or store payment details. We receive only the purchase status (active/inactive) via our subscription provider, RevenueCat.

What we do NOT collect

• Camera or photo access
• Location data
• Contacts or address book
• Behavioral analytics from third-party trackers
• Advertising identifiers

3. How we use your information

We use the data above to:

• Provide and maintain the app's core functionality
• Enforce free-tier limits and verify subscription status
• Save your session history and preferences across devices
• Send transactional emails such as account confirmation and password reset
• Respond to your support requests

We do not sell your data. We do not share your data with advertisers. We do not use your data to train machine learning models.

4. Third-party services

We rely on a small number of third-party services to operate Heater:

• Supabase — authentication and database hosting. Privacy policy.
• RevenueCat — subscription management. Privacy policy.
• Apple App Store and Google Play — distribution and payments.
• Vercel — hosting for this website.

These services may collect technical data (IP addresses, request logs) as part of normal operation. We have no control over their internal practices, but we have selected providers with strong privacy track records.

5. Data retention

We retain your account data for as long as your account exists. When you delete your account from within the app, we delete:

• Your authentication record
• All session history
• All usage counters
• Your preferences and bankroll settings

Deletion is permanent and cannot be reversed. Subscription cancellations must be handled separately through Apple or Google.

6. Your rights

Depending on your jurisdiction, you may have the right to:

• Access the data we hold about you
• Correct inaccurate data
• Delete your account and data (available via the in-app Settings screen)
• Object to processing or request data export

To exercise these rights, contact us via the support page.

7. Children

Heater is intended for users 18 years of age or older. We do not knowingly collect data from children under 18. If you believe a minor has provided us with personal data, please contact us so we can remove it.

8. Changes to this policy

We may update this policy occasionally. Material changes will be communicated via in-app notice or email to your registered address. Your continued use of Heater after a change indicates acceptance.
