Frequently Asked Questions

CosmoTest is a free personality and psychology test platform — "the universe's energy, every test in the universe." We offer 30+ original tests covering personality types, love styles, personal color analysis, career aptitude, zodiac personalities, and more. All tests are designed in-house, with no registration required.

Our tests are designed for self-discovery and fun — not as clinical or psychological diagnostics. Results reflect general tendencies based on 12 questions across 3 personality axes, placing you in one of 8 types. Think of them as a fun, thought-provoking mirror rather than a definitive verdict. For clinical assessment, please consult a licensed professional.

All tests are completely free and require no account or login. We're supported by Google AdSense ads, which may appear between test screens. We keep ad frequency low to preserve the test experience.

The official MBTI® is a licensed psychometric instrument administered by trained practitioners. CosmoTest is an independent personality exploration platform inspired by typology concepts but using its own original 3-axis frameworks and result characters. We do not claim to replicate or replace the official MBTI assessment — our results should be enjoyed as independent personality explorations.

Yes — tap Save Image on the result screen to download your result card as a PNG. You can also share via KakaoTalk, copy a direct link, or post to X (Twitter). Bookmarking the result URL (e.g., ?result=ETJ) lets you revisit anytime without retaking the test.

Possibly. Your mood and mindset on any given day can nudge borderline answers, shifting you to a neighboring type. This is completely normal — in fact, we encourage taking the same test a few times to see which result appears most often. That recurring result tends to reflect your dominant tendencies.

Tap Retake at the bottom of the result screen to start over. Results reflect a snapshot of your current tendencies — they're not fixed labels. You're also welcome to browse all 8 result types to find the one that resonates most with you.

CosmoTest is free to use, and Google AdSense ads help cover operating costs. We limit ad frequency to keep the test experience smooth, and we block inappropriate ad categories (adult content, gambling, etc.) in the AdSense console. Your support by allowing ads helps us keep the tests free.

Technically yes, but allowing ads helps us keep the site free. If you use an ad blocker, some elements may not render correctly. We promise to keep the ad experience as unintrusive as possible.

CosmoTest itself collects no personal data. Test answers and results are stored only in your browser's localStorage and never sent to any server. Google Analytics collects anonymous visit statistics, and Google AdSense may use cookies for ad personalization. See our Privacy Policy for full details.

No. Results are stored only in your own browser and are never transmitted to any server — so no one else can see them. They only become visible to others if you actively share them using the share buttons.

Yes — CosmoTest is mobile-first. It works smoothly in Safari, Chrome, Samsung Internet, and other major mobile browsers. Tap Add to Home Screen when prompted for an app-like experience.
