Privacy Policy

This Privacy Policy describes how Baldwinson Corporation ("we," "us," or "our") handles information in connection with the Cogniflux mobile application ("the App"). We are committed to protecting your privacy and being transparent about our data practices.

1. Data Controller

For the purposes of the EU General Data Protection Regulation (GDPR) and applicable data protection laws, the data controller responsible for your personal data is:

2. Information We Collect

Cogniflux is designed with a privacy-first approach. The App collects and stores the following information locally on your device:

• Caffeine intake logs (beverage type, caffeine amount, timestamp)
• User preferences and settings (e.g., target bedtime, display preferences)
• Derived data such as estimated caffeine and metabolite curves

Apple HealthKit Data

With your explicit permission, Cogniflux may read and/or write the following data types from Apple HealthKit:

• Caffeine intake (write, to log your caffeine consumption)
• Sleep analysis (read, to correlate caffeine timing with sleep data, if available)
• Heart rate (read, to provide insights into how caffeine may correlate with heart rate patterns)

HealthKit data is accessed only when you grant permission through the iOS Health permissions dialog. You can revoke access at any time in your device's Settings > Health > Data Access. HealthKit data is not used for advertising or marketing purposes.

Optional Data Sync

If you choose to enable sync features, certain data, including heart rate data read from HealthKit, may be transmitted securely to our private servers. Sync is entirely optional and disabled by default. You control which data types are synced, and you can disable sync at any time in the App's settings. An account is not required to use the core features of Cogniflux.

Error and Crash Reports

The App uses Sentry, a third-party error monitoring service, to collect crash reports and diagnostic data. This data may include device model, operating system version, app version, and technical details about the error. Crash reports do not contain your caffeine logs, HealthKit data, or any personally identifiable information.

Purchase Information

If you make a purchase or subscribe to a premium feature, payment processing is handled by Apple through the App Store and by RevenueCat, a third-party subscription management service. We receive a pseudonymous identifier and subscription status from RevenueCat to unlock premium features. We do not receive or store your payment details, credit card number, or Apple ID.

We do not collect personal information such as your name, email address, phone number, or location. The App does not require you to create an account.

3. How We Use Information

Information collected by Cogniflux is used for the following purposes:

• Core functionality: Your caffeine logs and settings are used locally to model caffeine levels, generate visualizations, and provide timing insights.
• HealthKit integration: HealthKit data is used on-device to enrich caffeine modeling with sleep and heart rate data, and to write caffeine records back to Health, if you choose.
• Optional sync: If you enable sync, heart rate and other opted-in data is transmitted to our servers to provide enhanced features and insights across sessions.
• Aggregated analytics: We may use anonymized, aggregated data that cannot be linked back to any individual user to improve the App and conduct research. This data contains no personally identifiable information.
• Error reporting: Crash and diagnostic data is sent to Sentry to help us identify and fix bugs, improving the App's stability for all users.
• Subscription management: A pseudonymous purchase identifier is shared with RevenueCat solely to verify your subscription status and unlock premium features.

4. Third-Party Services

We do not sell, rent, or share your personal data or caffeine logs for advertising or marketing purposes. We do not sell your data to data brokers or third parties. The App integrates with the following third-party services:

5. Data Retention

Your caffeine logs and settings are stored locally on your device for as long as you use the App. If you delete the App, all local data is removed from your device.

• Synced data: If you have enabled sync, data stored on our servers is retained until you request its deletion or delete your account. You may request deletion by contacting us at the email address below.
• Anonymized data: Aggregated, anonymized data that cannot be linked to any individual may be retained indefinitely for research and product improvement purposes.
• Sentry: Crash reports are retained by Sentry in accordance with their data retention policies (typically 90 days).
• RevenueCat: Subscription records are retained by RevenueCat as long as necessary to manage your subscription and comply with financial record-keeping requirements.
• HealthKit: Data written to HealthKit is managed by iOS and remains under your control via the Health app.

6. Your Choices

You have full control over your data:

• You can delete individual log entries within the App at any time.
• You can delete all local App data by uninstalling Cogniflux from your device.
• You can adjust App settings and preferences at any time.
• You can enable or disable data sync at any time in the App's settings.
• You can request deletion of any data stored on our servers by contacting us.
• You can revoke HealthKit access at any time via Settings > Health > Data Access on your device.

7. Security

Your caffeine logs and settings are stored locally on your device and benefit from the security protections provided by your device's operating system, including device encryption and biometric locks. Data transmitted to our servers and third-party services (sync data, Sentry crash reports, RevenueCat subscription verification) is sent over encrypted HTTPS connections. Data stored on our servers is protected using industry-standard security measures. We use commercially reasonable measures to protect all data that is transmitted and stored.

8. Children's Privacy

Cogniflux is not directed at children under the age of 13 (or the applicable age of consent in your jurisdiction). We do not knowingly collect information from children. If you believe a child has provided information through the App, please contact us so we can take appropriate action.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the "Effective Date" at the top of this page and, where appropriate, provide notice within the App. Your continued use of Cogniflux after changes are posted constitutes your acceptance of the revised policy.
