Your privacy is our top priority. All calculations are performed locally in your web browser using client-side JavaScript. Your birthday, survey responses, and personal information are never transmitted to or stored on our servers. We only collect anonymous analytics data to improve our services.

No, we do not sell your personal data. Since your birthday and test inputs are processed locally in your browser and never sent to our servers, there's no personal data for us to sell. We use Google Analytics and Microsoft Clarity for anonymous usage statistics only.

AI Life Summary converts your birthday into a deterministic numerical seed. That seed selects from a library of carefully written narrative components to create a consistent, shareable life-summary prompt for entertainment and self-reflection. The same birthday always produces the same result.

Our algorithm is deterministic by design, meaning the same input (birthday) always produces the same output (life summary). This is intentional so you can save and share a stable result. It should be treated as a birthday-seeded entertainment prompt, not as proof that your birthday determines your personality.

AI Test Lab tests are designed primarily for entertainment and self-reflection, not scientific personality assessment. While many users find their results surprisingly relevant and insightful, we encourage you to approach the results with an open mind - take what resonates and enjoy the experience without expectations of clinical accuracy.

Real Age is your chronological age based on your birthday. Mental Age and Energy Age are illustrative, for-fun scores generated from your inputs and lifestyle answers. They can be useful conversation and reflection prompts, but they do not measure cognitive ability, vitality, or health.
