Privacy Policy

Last updated: March 31, 2026

Privacy First

Noir. is designed with privacy at its core. Your learning content — courses, resources, and progress — stays on your device and is never sent to our servers. We use a small number of third-party services for analytics, error tracking, and subscription management, all with anonymous identifiers and no personally identifiable information.

1. Information We Collect

1.1 Information Stored Locally

All of the following information is stored exclusively on your device and never transmitted to our servers:

1.2 Analytics (PostHog)

Provider: PostHog Inc., hosted in the United States.

We collect anonymous usage events to understand how features are used and improve the app experience. This includes:

We also store anonymous user properties such as subscription status, current streak count, course count, daily goal setting, and total learning minutes. All data is tied to an anonymous, device-generated identifier. We do not collect your name, email address, or any other personally identifiable information through analytics.

1.3 Error Tracking (Sentry)

Provider: Functional Software Inc. (Sentry), hosted in the European Union (Germany).

We collect crash reports and performance data to identify and fix bugs:

Error tracking is only active in production builds. No personally identifiable information is attached to error reports.

1.4 Subscription Management (RevenueCat)

Provider: RevenueCat Inc., hosted in the United States.

We use RevenueCat to manage Pro subscription entitlements. Data processed includes:

Your payment details (credit card, billing address) are handled entirely by Apple and are never accessible to us or RevenueCat.

1.5 Payment Processing (Apple)

All purchases are processed by the Apple App Store. We do not receive or store any payment information.

2. How We Use Information

The limited information we collect is used solely for:

3. Data Storage and Security

3.1 Local Storage

All your personal learning data is stored locally on your device using secure device storage mechanisms. This data is protected by your device's security features (passcode, biometric authentication, etc.).

3.2 No Cloud Backup

We do not provide cloud backup or synchronization features. If you delete the app or lose your device, your learning data cannot be recovered. We recommend using your device's backup features (iCloud Backup) to preserve your data.

3.3 Data Security

We implement appropriate technical measures to protect the limited data we collect. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

4. Data Sharing and Disclosure

We do not sell, rent, or trade your data. Anonymous data is shared only with the following service providers, who process it solely on our behalf for the purposes described in this policy:

We may also disclose information if required by law or to protect our legal rights. If our company is acquired or merged, user information may be transferred as part of that transaction.

5. Third-Party Services

Noir. uses the following third-party services. Each provider has their own privacy policy governing their use of data:

When you open URLs in learning resources, you may leave the app and visit external websites. We are not responsible for the privacy practices of external websites.

6. Children's Privacy

Noir. is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us at gosset.dev@gmail.com.

7. Your Rights and Choices

7.1 Data Control

Since all your learning data is stored locally on your device, you have complete control over it:

7.2 Notifications

You can control notification permissions through your device settings or within the app's settings screen.

7.3 Subscription Cancellation

You can cancel your Pro subscription at any time through your Apple App Store account settings.

8. Data Retention

9. International Users

Noir. is available worldwide. Your learning content remains on your device. Anonymous analytics and subscription data is processed by PostHog and RevenueCat in the United States, and error tracking data is processed by Sentry in the European Union (Germany). By using the app, you acknowledge that this anonymized data may be transferred to and processed in these locations.

10. European Users (GDPR)

Noir. is developed by Antoine Gosset, based in France. If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, the following applies under the General Data Protection Regulation (GDPR):

10.1 Legal Basis for Processing

10.2 Your Rights

You have the right to access, rectification, erasure, restriction of processing, data portability, and objection.

11. California Privacy Rights

If you are a California resident, you have the right to know what personal information we collect and how it is used. Since we collect minimal information and store learning data locally, most CCPA rights are not applicable. For questions, contact us at gosset.dev@gmail.com.
