Privacy and measurement
We measure completed actions and arrivals from approved campaign links. You can exclude this additional measurement using the link below.
Saved in this browser
The save feature keeps names, settings and draw history in this browser. These values will not be reused for measurement.
Current traffic analytics
Cloudflare Web Analytics helps us understand page views and visits. The exclusion link below does not disable that existing analytics or Cloudflare delivery and security processing.
Operation counts
We count completed picks and team generation, and arrivals with approved campaign-link tags, using Japan time. Repeated operations count separately. We do not measure people, daily active users or return visits.
Fields sent
Only a schema version, random per-event ID, event type, mode, language and approved short campaign key go to the same-site endpoint. It adds receipt time and Japan-date. Names, participant counts, amounts, draw results, free text and full URLs are not sent.
Identification and provider
No measurement cookie or persistent device ID is added. The event ID only prevents duplicate retries. The request omits cookies and the referring URL. Cloudflare delivers the site and processes these counts. Cloudflare may process IP addresses for communication and security; this does not promise that IP addresses are never stored anywhere.
Retention and deletion
Scheduled maintenance deletes raw events and event IDs older than 30 days, and daily counts older than 13 months. Failures or free-tier limits may delay deletion. New collection stops if maintenance has not succeeded for 26 hours. D1 Free provides a 7-day recovery window, so deleted records may return after restoration; purge again before resuming. The app does not log inputs or IP addresses. Pages diagnostic logs are live-only under the official specification; maintenance Worker invocation logs are excluded. This does not guarantee the retention of all Cloudflare delivery, security or internal logs.
Exclude additional measurement
Use the link below to open an excluded page. Exclusion lasts within that document, including mode changes. Use the link again after reload, a new page or closing the browser. No persistent opt-out storage is added. The tools still work.
