Privacy Policy

Our Commitment

At Big Five Personality Test, we try to collect as little as possible about you. We built shareable results (/r/<id>) because it makes the test more fun — and that one feature is the only reason we store anything server-side at all. This page explains exactly what we keep, for how long, and why.

What We Store

When you complete the test, we save one record in our database so you can share a link to your result. Each record contains:

• Your five dimension scores (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) — numbers between 0 and 100
• Which archetype the scores map to (e.g. The Explorer)
• The optional nickname you typed (if you typed one — you don't have to)
• The language you took the test in (en, zh, …)
• The timestamp of the test
• A one-way hash of your IP address, used only for rate-limiting (we can't reverse it back to an IP)

That's it. We do not store your name, email, phone number, precise location, or individual question answers.

How Long We Keep It

All test result records are automatically and irreversibly deleted after 90 days. A scheduled task runs every day to remove anything older than that. If you want us to delete your result sooner, see "Deleting your data" below.

What We Don't Do

• We don't require you to sign up or log in
• We don't collect your name, email, or phone number
• We don't track your precise location (city-level or finer)
• We don't use your results for advertising targeting
• We don't sell your data to anyone
• We don't share individual results with any third party

Cookies & Storage

We use:

• localStorage in your browser to save your test progress so you can resume if you close the tab — this never leaves your device
• A theme cookie to remember light/dark mode
• Anonymous analytics (see next section)

You can clear all of this anytime from your browser settings.

Analytics & Third Parties

We use the following services to understand how the site is used and to run the site:

• Neon — our Postgres database provider (US East region), stores the result records described above
• Vercel — hosts the site and runs server functions
• Google Analytics — anonymous pageview counts, no personally identifiable information
• Ahrefs Analytics — traffic performance monitoring
• Google AdSense — displays ads on some pages; you can opt out of personalized ads at Google Ads Settings or at the Network Advertising Initiative opt-out page

External links on the site are not covered by this policy.

Deleting Your Data

Because we don't require accounts, the simplest way to delete a specific result is to let the 90-day window expire — it happens automatically.

If you need something deleted sooner (for example, you posted a link publicly and want it gone immediately), email us at support@bigfivepersonality.me with the URL of your result (e.g. bigfivepersonality.com/r/xK7mP2qA) and we'll remove the record within 7 days.

Children's Privacy

The test is intended for general audiences. We do not knowingly collect information from children under 13.

Changes to This Policy

If we change how we handle data, we'll update this page and bump the date below. Material changes will also be noted in our changelog.
