Everything you need to know about Know Yourself Better — privacy, scoring, technical details, and how to get the most out of the platform.
Know Yourself Better (KYB) is a free, private self-assessment platform that offers 100+ tests across 35+ categories — from personality and psychology to finance, career, AI literacy, leadership, relationships, and more. Each test uses multi-dimensional weighted scoring to give you a detailed profile of your traits, habits, or skills.
The platform is 100% client-side — no accounts, no tracking, no backend. Your data never leaves your browser.
Yes — completely and forever free. No paywalls, no premium tiers, no "unlock your full results" gimmicks, no ads, no data selling. Every test, every question, every result is available to everyone at no cost.
We believe self-discovery should be accessible to all. The platform is hosted on Vercel's free tier, and the only cost we incur is domain registration.
KYB was created by developers who wanted a self-discovery tool that respected user privacy. Most self-assessment sites either require accounts, track your data, push premium subscriptions, or serve ads. We wanted something different — a tool that gives you genuine insight without asking for anything in return.

New tests are added regularly — typically several per week. We prioritize tests that users request and topics that are under-represented in our catalog. If you have an idea for a test, email us at info@knowyourselfbetter.app.
No. KYB tests are educational and exploratory — they are designed for self-reflection and personal growth, not for clinical diagnosis, medical evaluation, or professional assessment.
Some tests (like ADHD screening, depression screening, or anxiety screening) use established clinical frameworks, but they are not diagnostic. They are meant to raise awareness and help you understand your experiences. If you're concerned about your mental health, please consult a qualified healthcare professional.
Some tests cover sensitive topics — including trauma, mental health screening, addiction assessment, and relationship dynamics. Each test's title and description make its subject clear so you can make an informed choice before starting. All answers are anonymous and stored only on your device — you can stop any test at any time, and your partial answers are not saved unless you complete and submit.
Exclusively in your browser's localStorage. Your answers, scores, and results never leave your device. There is no backend server, no database, no API that receives your data. Even we — the creators — cannot see your results.
This means your data is automatically deleted if you clear your browser's site data. To preserve your results, you can use the export feature to download them as a file.
No tracking cookies. We use Google Analytics (GA4) for anonymous, aggregated traffic statistics — basic information like page views, device types, and approximate geographic regions. This helps us understand which tests are popular so we know what to improve and what to build next.
Google Analytics uses its own cookies for session management. If you prefer not to be included, you can use a browser extension like uBlock Origin or Privacy Badger, or enable Do Not Track in your browser settings.
Critically: GA4 only sees that you visited a page. It never sees your test answers, scores, or any personal data.
No. KYB has no user accounts, no login system, no sign-up forms. You can take any test instantly, with zero friction. This is a deliberate design choice — we believe self-discovery should be immediate and barrier-free.
No. Your results are stored only in your browser's localStorage on your personal device. No one — not even the platform creators — can access them. They are as private as any file you keep on your own computer.
localStorage is tied to your specific browser and device. If you clear your browser data, switch browsers, or use a different device, your results will not carry over.
To preserve your results across devices or browsers, use the export/import feature available on the results page. You can download your data as a JSON file and import it on any other device.
Each test has 4-6 categories (dimensions). Each question belongs to one category and has a weight that determines its contribution. You rate each statement on a 1-5 scale (1 = Strongly Disagree, 5 = Strongly Agree).
Your score for each category is calculated as a weighted percentage of the maximum possible score in that category. Grade bands (A through F) map these percentages to easy-to-understand labels. Some tests also offer a combined overall score.
Each test displays results as letter grades for each category. The meaning of A-F depends on the test type:
Always check the test description for the specific interpretation of scores and grades.
Some tests are based on established frameworks and clinical screening tools (e.g., ASRS-v1.1 for ADHD, PHQ-9 for depression, GAD-7 for anxiety, MDQ for bipolar disorder). These are adapted for self-assessment and should not be considered diagnostic.
Other tests are designed by our team based on research, expert knowledge, and community input. They are meant for exploration and reflection, not clinical use. We clearly label the basis of each test in its description.
Yes. You can retake any test as many times as you like. Your previous results are saved in your browser's history so you can track changes over time. Each attempt includes a timestamp.
Yes. Your results page includes a history section showing all your past attempts for each test, with scores and dates. You can also export your full history as a JSON file for offline storage, or clear individual entries.
Yes. On your results page, each past attempt has a delete option that removes only that specific entry from your localStorage history. This lets you clean up old attempts without losing more recent ones. There is also a "Clear All History" option if you want to start fresh.
Guided journeys are curated sequences of multiple tests around a theme. For example, "Emotional Mastery" combines tests on stress resilience, emotional intelligence, overthinking, and trauma recovery. Each journey takes about 25-45 minutes total and gives you a broader understanding of yourself across related dimensions.
Most tests have 20-24 questions and take approximately 5-6 minutes to complete. Shorter tests (12-16 questions) take about 3 minutes. Guided journeys combine 3-6 tests and take 20-45 minutes total. Each test card shows the exact question count and estimated time.
KYB is built with vanilla HTML, CSS, and JavaScript — no frameworks, no build tools, no runtime dependencies. It runs 100% in the browser with no backend.
Yes. KYB is a Progressive Web App (PWA). Once you've visited the site, it can be installed on your device's home screen and used offline for most functionality. The service worker caches the core assets, so tests you've loaded before will work without an internet connection.
Yes — KYB is fully responsive and mobile-first. It works on any device with a modern browser: phones, tablets, laptops, and desktops. You can also install it as a PWA on Android and iOS for a native-like experience.
Yes. From the results page, you can:
Sharing is always opt-in — nothing is shared automatically.
Yes, accessibility is a priority. KYB supports:
prefers-reduced-motionKYB runs on all modern browsers — the latest two versions of Chrome, Firefox, Safari, and Edge. Internet Explorer is not supported. The site uses vanilla HTML/CSS/JS with no experimental APIs, so compatibility is broad and reliable.

It depends on what you're curious about! Here are some popular starting points:
Use the guided journeys for thematic deep-dives. Use the sort dropdown to find popular tests, newest additions, or filter by category with the chip buttons. The search bar lets you find tests by keyword instantly.
Absolutely. KYB works great for team-building, workshops, coaching, and classroom settings. Since there's no account system, each person uses their own device and their data stays private. Recommended tests for teams: Emotional Intelligence, Conflict Resolution Style, Delegation Mastery, Leadership Style Assessment, and Communication Style.
Unfortunately, no. localStorage is tied to your browser profile. If you cleared your site data without first exporting your results, they cannot be recovered. This is a privacy feature — we don't store your data on any server.
To prevent this in the future, use the export feature on the results page to back up your data regularly.
Yes, generally. KYB is a static site with no tracking scripts beyond Google Analytics. Ad blockers may block the GA script and analytics icons, but the site itself — all tests, results, and features — will work normally. If you use an aggressive blocker like uBlock Origin in strict mode, only the Google Analytics call is affected; everything else loads fine.
Try these steps in order:
We welcome feedback! If you encounter a bug, have a suggestion for a new test, or want to improve an existing one, email us at info@knowyourselfbetter.app.
The stats on the homepage (test count, question count, dimension count) are calculated dynamically from the test data. They update automatically as new tests are added. If you see a discrepancy, it's likely due to a cached version of the page — a hard refresh should fix it.
