Privacy Policy

We value your privacy. This policy explains how we collect, use, and protect your data at SchulteGrid.app.

Last Updated: May 2026

Information We Collect

Voluntary Information

If you create an account, we collect personal data such as your email address, username, and authentication details so we can provide secure access to your SchulteGrid.app account.

Usage & Training Data

We collect game performance statistics, including scores, completion times, training dates, and related progress signals, to provide progress tracking and future cloud synchronization features.

Technical Data

We may process standard server logs, IP addresses, browser types, device information, and diagnostic events for security, fraud prevention, reliability, and product diagnostics.

How We Use Your Data

We use your data to personalize your training experience, synchronize progress across devices, secure your account, troubleshoot product issues, and maintain the reliability of SchulteGrid.app.

If we send product updates, we will provide opt-out options where required by applicable law.

Data Storage & Security

We use industry-standard safeguards, including SSL/TLS encryption for data in transit and appropriate encryption or access controls for data at rest.

Users who do not register will continue to have training data stored strictly in local browser cache, including localStorage. Local browser data stays on your device unless you choose to use account-based or cloud synchronization features in the future.

Third-Party Services

We may use secure hosting providers, authentication services, analytics tools, or infrastructure vendors to operate and improve SchulteGrid.app.

We will never sell or rent your personal data to third parties.

Depending on your location, you may have the right to access, update, correct, export, or request deletion of your registered account and personal data at any time.

You may also have rights to object to certain processing, restrict processing, withdraw consent where consent is used, or opt out of certain disclosures under applicable privacy laws.

Policy Updates

We may update this Privacy Policy as SchulteGrid.app evolves, including when account, cloud synchronization, or progress tracking features are introduced.

When changes are material, we will take reasonable steps to notify registered users or present the updated policy clearly within the service.

This policy is intended to be transparent and forward-compatible as SchulteGrid.app grows from a local browser training tool into optional account-based services.
