PHQ-9 Check-In

PHQ-9 Check-In brings the standard PHQ-9 depression screening questionnaire into Chrome's side panel — so you can check in with yourself in about two minutes, without opening a new tab or app. WHAT IT DOES - Walks you through all 9 PHQ-9 items, one question at a time, plus the standard functional-difficulty question - Scores your result (0–27) and shows the standard severity band: Minimal, Mild, Moderate, Moderately severe, or Severe - Lets you save results to a private History tab to see how things move over time - Shows a simple trend chart across your saved check-ins - Lets you export your history as a plain-text file, delete individual entries, or clear everything - Includes a plain-language "About" tab explaining the scale PRIVACY, FIRST - No account, sign-in, or personal information required - No servers, no analytics, no tracking, no ads - Your answers and history are stored only in this browser, using Chrome's local storage — they never leave your device - You can export, delete, or clear your data at any time; uninstalling the extension removes it permanently !!! IMPORTANT !!! PHQ-9 Check-In is a screening aid, not a diagnostic tool. It's designed to support a conversation with a doctor or mental health professional — not replace one. If you're having thoughts of self-harm, please reach out to a professional or a crisis line (in the US: call or text 988) regardless of your score. Built for anyone who wants a quick, private way to notice patterns in their mood over time.
