PRIVACY
You can pick numbers, run the analysis and see your tickets without an account. This page lists everything the site stores and why. Last updated 25 October 2026.
If you give us your email address
Tickets and printing never need an email. If you choose to enter one for the draw tracker or a link to reopen your tickets on another device, we store the address, a one-time verification link token and when it expires, the time of your last request, whether you have confirmed the address, and a random session identifier from your browser. We use it only to send that link and to switch on draw logging after you confirm. We do not send newsletters or marketing, and we do not sell or share the address.
We keep your email address until you ask us to delete it.
If you log draws
Each draw you log in the draw tracker is stored with your browser's random session identifier, the time, and your IP address. The IP address is kept to detect abuse of the tracker.
Number popularity (Hot and Cold)
When you run an analysis on numbers you picked yourself, we add one to a running count for each of those numbers. Only the counts are stored, never your pool, email or IP address. To stop one visitor from being counted many times a day, we store a one-way code made from your IP address, the game and the date. It cannot be turned back into your IP address, and it is deleted after two days.
Stored in your browser
Your browser keeps your selected numbers, game mode, custom payout tables and draw-tracker totals in local storage so they are still there when you come back. Three cookies are set: a random session identifier (one year), a signed unlock token after you confirm your email (30 days), and a short-lived copy of your tickets while you return from the confirmation link (five minutes). Clearing your browser's site data removes all of these.
Analytics
We use Vercel Web Analytics, Google Analytics and Microsoft Clarity to understand how the site is used: pages viewed, device and browser type, approximate location, and (for Clarity) recordings of clicks, scrolling and page interactions. These services set their own cookies and process this data under their own privacy policies. We do not send your email address to them.
Who processes the data
The site runs on Vercel. Database records are held by Supabase, and confirmation emails are sent by Resend. Each processes data only to provide its service to us.
Deleting your data
Email privacy@kenoengine.com from the address you used and we will delete your email record and any draws logged under your session. The number counts cannot be traced to you, so there is nothing personal in them to delete.
Age
Keno Engine is for adults of legal gambling age where they live, and is not meant for anyone younger.
