Privacy Policy

Last updated: 19 July 2026

The short version

OngLai4D has no user accounts and sets no tracking cookies. Your watchlist, win/loss tracker and theme preference live only in your own browser. Photos you submit for ticket scanning or dream lookup are processed transiently and not kept. We collect the minimum needed to run the site.

Data stored in your browser only

The watchlist, win/loss tracker, prediction-game scores and theme setting are saved in your browser's local storage. This data never leaves your device and is never sent to our servers. Clearing your browser data deletes it.

Photos you submit

When you use the ticket scanner or the dream photo lookup, the photo is resized on your device, sent to our server, and forwarded to Anthropic's Claude API to read the ticket or identify the dream subject. The photo is processed for that single request and is not stored by us afterwards. Do not include personal documents in photos — only the ticket or subject you want analysed.

Technical data

  • IP addresses are used transiently for rate limiting and abuse protection (on the site and the public API). We do not build profiles from them.
  • Hosting logs & analytics — the site is served by Cloudflare, which processes standard request logs; we may use privacy-friendly, cookie-free aggregate analytics (e.g. Cloudflare Web Analytics) to understand traffic.
  • Push notifications are strictly opt-in. If you subscribe, we store the push subscription endpoint your browser generates so we can deliver notifications; unsubscribing removes it.
  • API keys — if you request a developer API key by email, we keep the email address you contacted us from and per-key usage counts (requests per day) to enforce quotas.

What we don't do

  • No user accounts, no passwords, no sign-up.
  • No tracking cookies and no sale of personal data to anyone.
  • No collection of bets, spending, or gambling activity — the calculator and tracker run entirely in your browser.

If we introduce advertising in future, this policy will be updated first to describe exactly what the ad provider collects.
