Learning in the app

DuoTecho stores learning progress, lesson completions, practice history, your daily goal and project checklist progress on your device. The initial version does not require an account. This information is used to show your progress and suggest practice. Your device's backup settings may affect whether app data is included in a device backup.

The initial app does not include advertising, cross-app tracking or a developer-operated account service. Its learning history is not sent to us. If you choose to reset progress in the app, the saved learning history is removed from that installation.

Lesson updates

When the app opens, it requests a public lesson catalog so reviewed content can be updated. This request does not include your answers, learning progress or an account identifier. The hosting provider receives connection information such as your IP address and requested URL to deliver the catalog. If the request fails or times out, the app uses available cached or bundled content.

External websites and tools

Lessons may link to source material or third-party tools. Opening those links sends you to the relevant provider, whose privacy policy applies. We do not receive access to your accounts with those providers. Avoid entering personal or confidential information into a tool when practicing unless you understand how that provider handles it.

Website and support

When you visit our website, the hosting provider processes connection information needed to deliver the page, such as your IP address and requested URL. When you email support, we receive your email address and the information you choose to send so that we can respond. Do not include passwords or sensitive personal documents in support requests.

Changes and contact

We update this policy when the product's data practices change. Questions and requests can be sent to roy@techguyverlabs.org. Updated 12 October 2026.
