Mental Wellness Calc takes privacy seriously — especially for sensitive mental health data. All assessments run entirely in your browser. Nothing you answer is transmitted, stored or processed on any server.
Every tool on this site runs locally in your browser using JavaScript. Your mental health assessment answers, scores and reflections are never sent anywhere. They exist only in your browser session and are gone when you close the tab.
We use browser localStorage only to remember your light/dark theme preference. This data never leaves your device and contains no personal or health information.
We use Google Analytics (anonymised, aggregated) to understand which tools are most used. No individual-level data is collected. Opt out via Google's opt-out tool.
We display ads via Google AdSense and Adsterra. These use cookies for ad targeting. You can manage this via Google Ad Settings or your browser's privacy controls.
Some pages include Amazon affiliate links. We earn a small commission on qualifying purchases at no extra cost to you. We only recommend products we consider genuinely helpful.
If you subscribe via our email form, your address is stored with Kit (ConvertKit). You can unsubscribe from any email. We never sell or share email addresses.
All tools on Mental Wellness Calc are for self-reflection and informational purposes only. They are not clinical assessments, diagnoses, or medical advice. No tool on this site replaces professional mental health care. Always speak with a qualified healthcare professional about mental health concerns.
