NeuroConstruct Privacy Policy

The website does not require account registration or sign-in, and we do not ask for or directly collect personal information such as your name or contact details.

However, to provide iOS application features and to improve the Services, we may automatically collect or process the following categories of information:

• Photos and media library access: For photo organization apps (including Sakusaku Photo Organizer), we access the photo library on your device to provide features such as viewing, organizing, and deleting photos. All of this processing takes place locally on your device; we do not transmit or store your photo data on our servers or those of third parties.
• Location (GPS) information: For weather apps (including Weather Chart Pro) and field GPS management apps (including SiteMark), we obtain device location through the operating system after your clear permission, to show local weather and provide certain features. Location data is used only to provide those features and is not persistently stored or used for tracking on our or third-party servers in a manner that identifies you.
• App activity and usage data: Depending on the app, we may collect data such as study progress (e.g. NeuroQuest), settings, or in-app activity. These are used to operate features and, where applicable, to sync data across your devices via iCloud.
• Payment-related information (anonymized): Used to manage in-app purchase status, unlock paid features, and restore purchase history.
• Device information and crash logs: Used to improve app quality and fix defects.

We use the following external services to operate the Services, process payments, and analyze access. Each provider handles information under its own privacy policy.

• Apple Inc. (App Store / CloudKit): In-app payments and, for supported apps, secure synchronization of user data via iCloud (e.g. study progress sync where available).
• RevenueCat, Inc.: Verification and management of in-app purchases and subscription status.
• Supabase, Inc.: Delivery of problem data to applications and operation of backend systems.
• Vercel Inc. (Vercel Analytics): We use this to understand traffic and usage of the website we operate. It is designed with privacy in mind, does not use tracking cookies for cross-user tracking, and aggregates anonymized access data.

Because we do not directly collect or retain personal information such as names and contact details through the Services in the manner described above, we generally do not disclose personal information to third parties. This does not apply where disclosure is required by law or for other legitimate reasons (e.g. lawful requests).

You may use settings within each iOS app (for example, a function to completely erase study data in study-related apps) to reset or delete usage data stored on the device and in iCloud within the limits of the feature. Photos in photo organization apps are managed in the system photo library; photo data is not sent to our servers.

The Services may contain links to external sites. We are not responsible for how personal information is collected or handled on those sites. Please review the privacy policies of linked websites.

We work to protect information by appropriate means, including using SSL/TLS encryption for data communications where applicable, so that you can use the Services with confidence.

We may change this Policy from time to time due to new or amended laws or changes to the Services. Material changes take effect when posted within the Services. Continued use after changes constitutes your acceptance of the updated Policy.
