Privacy
This notice explains what IQ Centre collects when you use iqcentre.uk, why, and what you can do about it. We are the data controller. Contact:
What we collect, and why
| What | Why | Legal basis |
|---|---|---|
| Your test answers, how long each took, your memory span and your score | To mark the test, show your result and keep it in your account | Providing the service you asked for |
| Your email address (and name and profile picture if you sign in with Google) | To give you an account and contact you about your membership | Providing the service |
| Membership status and payment references from Stripe | To give members access and handle cancellations and refunds | Providing the service; legal obligations for financial records |
| When you join: the wording you agreed to, the time, your IP address and your browser type | A record of what you agreed to, kept with the payment, in case a payment is questioned | Our legitimate interest in being able to show what was agreed; legal obligations |
| Anonymous usage events, such as "started the test" or "finished the test", with a random number for that page view (nothing is stored on your device for these) | To see where the site is confusing and improve it | Our legitimate interest in running a site that works |
| A Google Ads cookie, only if you choose "Allow" | To see which adverts bring people to the site | Your consent, which you can withdraw |
Answers to the puzzles are stored with an item reference, not with anything about you except your account if you have one. We use them, without your identity, to check how hard each puzzle really is and keep scoring accurate.
Payments
Card payments are handled by Stripe. Your card number goes straight to Stripe and we never see or store it. Stripe's privacy policy is at stripe.com/privacy.
Who else handles your data
- Supabase (account sign-in and our database)
- Netlify (hosting the website)
- Stripe (payments)
- Resend (sending emails about your membership)
- Google (only if you sign in with Google, or allow the advertising cookie)
Some of these companies store data outside the UK. Where they do, they use the safeguards UK law requires, such as the UK International Data Transfer Addendum.
Cookies and storage on your device
The site stores a few things in your browser so it works: your sign-in, your test progress (so a refresh doesn't lose your answers), and whether you allowed the advertising cookie. These are necessary for the site and don't track you elsewhere. The only tracking cookie is the Google Ads one, and it's set only if you choose "Allow". To change your choice, clear this site's data in your browser and you'll be asked again.
How long we keep things
- Your account and results: until you ask us to delete them. Email us and we'll delete your account and everything linked to it.
- Payment records: 6 years, because tax law requires it. These are kept by Stripe and include no test results.
- Results from tests taken without an account, and usage events, aren't linked to you.
Your rights
You can ask us for a copy of your data, to correct it, to delete it, to restrict or object to how we use it, or to move it elsewhere. Email iqcentreuksupport@gmail.com from your account's email address. We'll reply within a month. If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.
Children
The site isn't aimed at children under 13, and we don't knowingly collect their data.
