Dizzy uses functional storage to remember your preferences, and analytics to understand website usage. Choose what you allow. You can change it any time from the footer. How we handle your data
Version 1 · Updated 23 September 2026
Dizzy is run by Harry Hartley, a sole trader based in the United Kingdom. He decides how and why your data is used, which makes him the controller of it under UK data protection law.
To ask anything about your data, or to use any of your rights, email privacy@dizzy.gg. You do not need a Dizzy account to write to us.
This is an early version of our notice. It says what we already do and what we have already decided. Where a decision is still open, it says so. A fuller notice will replace it.
What we hold about you depends on how you came to be on Dizzy.
We never ask for your date of birth, or for sensitive data such as your health, ethnicity or beliefs.
The law asks us to name a legal basis for each use of your data. These are ours.
If you never signed up and we hold your results because we imported them from start.gg or Challonge, we use them under legitimate interests only while they serve a community's record or ranking, or because you asked us to import them yourself.
We never send you marketing. Notifications and event announcements are service messages about things you take part in.
When you register for an event, the event's host and Dizzy share responsibility for your registration and check-in details. The host sees the list for their own event: names, tags, whether you have arrived and whether you have paid.
What happens to your results after that, including your ratings and your public profile, is Dizzy's responsibility alone.
Entry fees are paid into the host's own Stripe account. Stripe collects your card details and email address on its own page. Dizzy never sees them.
Under review
The written arrangement setting out what hosts are responsible for, and what we are, is still being drawn up.
Under review
Whether players who never signed up should be listed for search engines, and how API access is given and controlled, are both being decided.
These companies handle your data only on our instructions, under written data protection terms.
Vercel, PlanetScale, Railway and Stripe are US companies, so your data may be reached from the US even when it is stored in the UK. For those transfers we rely on the UK's data bridge with the US, or on contract clauses approved for UK transfers.
Under review
We are still confirming some of the details, including which region Railway keeps our analytics data in.
Your data sits in two layers, and deleting works differently for each.
In a small community, removing a name does not make you anonymous. People who were at an event may still know who placed where. So we treat the record as your personal data even after your name is gone.
The same applies if you never had an account and object to your record being public: we remove your name from every copy of it, and the matches stay. Your opponents' results are their record too.
Under review
You cannot delete your account from your settings yet. Until you can, email privacy@dizzy.gg and we will do it for you. Removing a name from every copy we hold is also still being finished, so tell us if you find one we missed.
You can ask us to:
You do not need an account for any of this, and it is free. Email privacy@dizzy.gg and tell us which player profile or event it is about. We may ask you to show it is you, for example through the start.gg or Challonge account the results came from. We will reply within one month.
Under review
Ways to do these things yourself on the site are being built. Until then, email works for all of them.
If you are unhappy with how we handle your data, you have the right to complain to us (under section 164A of the Data Protection Act 2018). Email privacy@dizzy.gg. We will confirm we have it within 30 days, look into it, and tell you what we found and what we did.
You can also complain to the Information Commissioner's Office (ICO), the UK's data protection regulator, at any time, whether or not you have complained to us first. Visit ico.org.uk/make-a-complaint or call 0303 123 1113.
Under review
We have not yet set a fixed time for keeping each kind of data. A retention schedule is being written, and this notice will say what it decides.
Some times are already set. Notifications are deleted after 90 days. Sign-in cookies expire after 7 days. The IP address and browser a session came from are kept until 30 days after the session ends. Premium payment records are kept for 6 years. Until the schedule is published, everything else, including the competitive record, is kept for as long as Dizzy runs.
Under review
Dizzy does not ask for anyone's age, and young players do take part in events. We are reviewing what that means for how we handle their data.
The version number and date at the top of this page change whenever the notice does. If a change widens what we keep on your device, we will ask for your cookie choice again.
