PRIVACY & TRANSPARENCY

Less data.
More control.

Practice progress

Step checkboxes are stored in your browser’s local storage on this device. They are not sent to us. Use “Reset this practice” to clear that tutorial’s progress, or clear this site’s browser data to remove all progress. If storage is blocked, the page still works, but progress may not persist.

Gap explainer

Your selections and text stay in the current page’s memory. We do not send them to an AI model or save them in local storage. “Clear everything” removes the displayed inputs and output. Your browser may independently retain form state or clipboard content. Copying wording places it on your device clipboard.

Email and analytics

Newsletter signup is disabled until the sending domain, backend and consent flow are configured. No email address is collected by this site. No analytics, tracking pixels, advertising cookies or third-party fonts are loaded by the application. The hosting provider may process normal connection logs.

External AI tools

Following a link or pasting a prompt into another service is subject to that service’s privacy terms, account settings and limits. Use synthetic examples and approved workplace tools. Do not upload confidential or personal financial data just because a tutorial mentions a tool.

Funding

No affiliate links. No active sponsors. Any future sponsored tutorial will be labelled prominently and remain subject to our editorial standards.
