Privacy Policy

Last updated: January 17, 2026

1) Who we are

This website, universaliqtest.com ("Universal IQ Test", "we", "us"), is operated by an individual based in Bern, Switzerland.

Contact: contact@universaliqtest.com

2) What this policy covers

This Privacy Policy explains what information we collect, how we use it, and the choices you have when you use our online IQ test, statistics pages, leaderboards, and result links.

3) Information we collect

A) Test and result data

When you take the test, we process and store data such as:

Your answers and whether they were correct
Timing data (e.g., total time and/or per-question timing)
Your calculated result (e.g., score, percentile, category, rankings)
Validation/quality signals (e.g., whether an attempt is treated as "validated")

B) Demographics (self-reported)

If you provide them, we store self-reported fields such as:

Age group/band
Gender (as offered by the form)
Education level
Study area
Country

C) Email (recovery / linking attempts)

If you provide an email address, we store it to:

Link multiple attempts to the same user (history/recovery features)
Help you recover results

Important: If your recovery process allows recovery based on email alone, then anyone who knows that email may be able to retrieve associated attempts/results. Please use this feature carefully.

D) Device/browser identifiers ("fingerprints")

We use device/browser identifiers (including fingerprint-style signals) for:

Linking attempts when users return
Preventing abuse and protecting the integrity of statistics and leaderboards
Detecting suspicious or automated submissions

We do not use fingerprinting for advertising.

E) Technical logs

Like most websites, our servers and infrastructure may log technical information such as:

IP address
Browser/device details (user agent)
Timestamps, pages requested, error and security logs

4) How we use information (purposes)

We use the information above to:

Provide the test and display your results
Compute dataset statistics and charts (including "validated vs all" views)
Maintain integrity of rankings and detect low-quality or abusive submissions
Provide result recovery/history when you provide an email
Secure, maintain, and improve the website

5) Public results, share links, and leaderboards

Result pages are accessible via a unique link (e.g., /r/...). Anyone with the link may be able to view the result. Please treat result links as public.

Leaderboards and "recent results" components may display information such as:

Nickname
Score / percentile / timing summary
Country (if available)
A link to the result page

If you want a publicly visible result removed from leaderboards or public lists, contact contact@universaliqtest.com with the result link.

6) Analytics and cookies (Google Analytics)

We use Google Analytics to understand website usage (e.g., page views, device/browser category, approximate location derived from IP, and interactions). Google Analytics typically uses cookies or similar technologies.

You can limit analytics by:

Using browser settings to block cookies
Using browser privacy features / content blockers
Using Google's opt-out mechanisms (where available)

7) Sharing and service providers (processors)

We use third-party providers to operate the Service. These providers may process personal data on our behalf:

Hosting/CDN: Vercel
Database: Neon
Email sending: Resend
Analytics: Google Analytics (Google)

We share data only to the extent necessary to run the Service (hosting, storage, email delivery, analytics, security).

8) International data transfers

Our providers may process data in countries outside Switzerland/your country (including the United States). Where required, we rely on appropriate safeguards (such as contractual protections) for cross-border transfers.

9) Data retention (safe defaults)

We retain data as follows (unless we decide to shorten these periods later):

Test attempts + performance/timing + demographics: retained as long as needed to provide the Service and to maintain long-term aggregate statistics (often long-term/indefinite).
Email used for recovery/linking: retained until you stop using the Service for an extended period; as a default we retain for up to 24 months after the last activity associated with that email, then may delete or anonymize.
Device/browser identifiers (fingerprints): retained for integrity/recovery/linking purposes; default up to 24 months after last activity.
Server/security logs: typically retained for up to 30 days (longer if needed for security investigations).
Analytics data: retained according to our Google Analytics settings.

10) Your choices and rights

Depending on where you live (e.g., Switzerland, EU/EEA), you may have rights to request access, correction, restriction, objection, or deletion of personal data.

You can contact us at contact@universaliqtest.com. For privacy and security, we may ask you to verify control of an email address or a specific result link before acting.

11) Children

The Service is intended for users 12+. If you believe a child under 12 has provided personal data, contact contact@universaliqtest.com and we will take appropriate action.

12) Security

We use reasonable measures to protect data. No online service can guarantee absolute security. Please do not share result links if you want results to remain private.

13) Changes to this policy

We may update this policy from time to time. We will update the "Last updated" date when changes are made.
