Privacy Policy
Read how Lucky By Birthday handles birth details, local preferences, analytics, advertising choices, and privacy requests.

Reading inputs and processing
Your chart and current/previous weekly numbers run on your device. Birth inputs stay in page memory, not browser storage, and are not sent for the local reading. Only pressing the optional AI button sends your birth date, optional hour, language and chart to Cloudflare. OpenAI receives the chart, hour, language and week, not the raw birthday. Chart data can still be personal information. No name or account is required. Ordinary hosting and optional analytics are described below.
Storage
Cloudflare provides hosting, security, and temporary caching. Reading inputs and results may be cached until the next weekly refresh. Browser storage remembers interface preferences, referral codes if present, and analytics choices until cleared. Provider operational logs may have separate retention; cache expiry does not imply deletion of all provider logs.
Optional analytics and cookies
Google Analytics starts only after Allow analytics. It may process page visits, interactions, device/browser information, and cookie identifiers. We do not intentionally send the entered birth date or hour to Analytics. Declining does not limit features. Change your choice with Analytics cookie settings in the footer. Withdrawal stops future measurement and removes accessible first-party GA cookies, not data already sent. Google may set _ga and _ga_* cookies with lifetimes depending on settings and browser controls. We do not claim a fixed Analytics retention period because the account setting has not been verified.
Advertising and external resources
Ads are currently paused: the AdSense advertising script is not loaded. The publisher verification tag and ads.txt remain. Analytics consent is not advertising consent; ad placements and required consent must be reviewed before ads resume. Google Fonts requests send ordinary connection information to its servers. Linked sites have their own privacy practices.
Requests and children
For access, correction, deletion, or other applicable privacy requests contact [email protected]. Do not email unnecessary sensitive records. We aim to respond within 30 days. This service is not intended for children under 13, or under 16 in the EEA. Contact us if a child may have supplied information. Lucky By Birthday operates this site; this notice will be updated when processing changes.
Give your lucky numbers a small ritual
Nothing is saved until you choose Save. Only the week, activity and tried/not-yet status stay in this browser (up to 8 weekly entries, until deleted); no birthday, chart or notes are stored. This is not sent to us or synced between devices. Anyone using this browser may see it. Import this file into your calendar to create a weekly reminder at Sunday 00:00 KST. Check its local time, alerts and recurrence before saving; edit or delete it in your calendar. We do not send push notifications or subscribe you automatically.
Email inquiries
Messages to our contact addresses pass through Cloudflare Email Routing to the publisher’s Gmail inbox. Cloudflare and Google process the sender address, message contents and any attachments to route and handle the inquiry. Send only what is necessary; please do not attach birth records or identity documents. Email correspondence is separate from the calculator’s on-device data and browser deletion controls.
