Privacy Policy

Effective: August 12, 2025

M31Lab LLC values your privacy. We collect minimal personal information, such as messages sent via our contact form, solely for the purpose of responding to inquiries.

General Information

We do not sell personal information. We share data only with trusted service providers (e.g., Google for analytics and Stripe for payment processing) to operate and improve our services.

Our website includes an optional game feature. Game progress and high scores are stored only in your browser’s local storage. This information is not sent to our servers or shared with third parties, and will be deleted if you clear your browser data.

We use Google Analytics to gather anonymous usage data to help us improve our website and apps. This may involve the use of cookies or similar tracking technologies.

If you are in the EU/UK, our legal basis for processing personal data includes performance of a contract (processing donations you initiate), legitimate interests (analytics and responding to inquiries), compliance with legal obligations (e.g., tax and accounting), and consent where required.

We retain contact messages for up to 24 months before deletion. Donation transaction records are retained for as long as necessary to comply with legal, tax, and accounting requirements. Analytics data is retained in accordance with Google’s data retention policies.

We implement reasonable technical and organizational measures to protect your information, though no method is 100% secure.

You may disable cookies in your browser, use the Google Analytics opt-out, or block scripts. Please note that Do Not Track signals are not widely honored.

You can learn more about Google’s data practices here: Google Privacy Policy and opt out here: Google Analytics Opt-out.

Our services are not directed to children under 13, and we do not knowingly collect information from them.

We may update this Privacy Policy from time to time. We will post the updated version on this page with a new effective date.

If you have questions about this policy, contact us at [email protected].

Donations & Payments

If you choose to make a donation, we collect information necessary to process the transaction (such as your name, email, donation amount, currency, and transaction identifiers). Payments are handled by our partner, Stripe, which collects and processes sensitive payment information (like card details) directly. M31Lab LLC does not receive or store full credit card numbers.

For details about how Stripe processes personal data, please see the Stripe Privacy Policy. Donation transaction records may be retained as required for tax and accounting compliance.

Pa' Kendo App Privacy

The Pa' Kendo app is developed by M31Lab LLC and is designed for educational purposes. The app does not require you to create an account and does not collect personally identifiable information.

The app may store non-personal data locally on your device, such as quiz scores, progress, and user preferences, solely to provide core functionality. This information is stored on your device and is not transmitted to our servers or shared with third parties.

No location data, contact information, photos, or microphone/camera input is collected by the app. We do not use third-party analytics or advertising tools within Pa' Kendo.

While the app does not currently collect any analytics data, we reserve the right to implement anonymized analytics in the future to help improve functionality and enhance user experience. Any such analytics would not collect personally identifiable information and would comply with all applicable privacy regulations.

Apple App Store Compliance

Pa' Kendo is distributed via the Apple App Store and adheres to the Apple App Store Review Guidelines and App Privacy requirements. Our App Privacy details in App Store Connect currently indicate that the app does not collect data. If we later implement anonymized analytics, we will update the App Privacy details before release to accurately reflect the data categories and purposes (e.g., product interaction, diagnostics) and confirm that such data is not linked to you and is not used for tracking as defined by Apple. Pa' Kendo does not use IDFA, does not display the App Tracking Transparency (ATT) prompt, and does not use third‑party advertising SDKs.

Google Play Store Compliance

Pa' Kendo is distributed via the Google Play Store and adheres to Google Play’s Developer Program Policies and Data safety requirements. Our Data safety form in Play Console indicates that the app does not collect or share personal data. If anonymized analytics are implemented, the Data safety form is updated before release to accurately describe the data collected, its purpose, and confirm that such data is not linked to you and is not used for advertising or tracking. Pa' Kendo does not use the Advertising ID for tracking or personalized ads.

If you choose to contact us from within the app, any information you provide (such as your email address and message content) will be used solely to respond to your inquiry, in accordance with the General Information section of this Privacy Policy. You may also contact us directly at [email protected].

Children's Privacy

The Pa' Kendo app is not directed to children under the age of 13, and we do not knowingly collect any personal information from children. Parents or guardians who believe that their child has provided personal information may contact us to request deletion.
