Privacy Policy

LuckyNumberz is developed and operated by Emre Yılmaz, an individual developer based in Türkiye ("we", "us"). This policy explains what the LuckyNumberz mobile app and its backend service do with data, in plain language. The English text is the binding version.

The short version

You can use LuckyNumberz without an account. If you choose to sign in (with your e-mail address, Apple or Google), we store your e-mail address, an optional name, and the numbers, saved lines and settings you keep in the app so they follow you to other devices.

Marketing e-mails are sent only if you tick the box for them, and you can untick it in the app at any time.

Without an account, the only data we store is what is needed to send you draw notifications, and only if you turn notifications on.

The app shows advertisements served by Google AdMob. Google may process device identifiers for that purpose under its own privacy policy.

We do not sell data, we do not run analytics or tracking SDKs, and we do not build profiles of you.

What we collect, and why

Account (optional). When you sign in we create an account holding your e-mail address (for Apple sign-in this may be a private relay address), an optional display name, the sign-in provider identifiers Apple or Google give us, the date you created the account, the time of your last sign-in and the type and model of the device each session was opened on (for example "ios iPhone"). With it we keep one synced document per account: your region and language choice, default game, notification preference, the personal details you entered for Personal and Zodiac numbers (name, birth date, lucky number) and your saved lines. Signing in by e-mail sends you a 6-digit code, valid for 10 minutes; we store it only as a one-way hash and delete it within 75 minutes. We never store passwords. Session tokens are stored hashed on our side and in the secure storage of your device.

Marketing e-mails (optional). If you tick "product news and offers by e-mail" we record that consent with its date and may send you occasional e-mails about LuckyNumberz. You can withdraw the consent from the Profile tab at any time; we stop immediately.

Draw notifications (optional). If you enable notifications, the app registers a push token with our service, together with the games and notification types you chose, your app language and your platform (iOS or Android). This is what lets us send you a message when a new draw result arrives. The push token is a random identifier issued by your platform; it does not identify you personally. You can turn notifications off at any time in the app, after which we stop sending them.

Region. The app reads your device locale on the device to decide which lottery games to show first (for example, Powerball in the United States). The two-letter country code is sent to our service so it can return the right games. It is not stored.

Technical data. Like every internet service, our servers receive your IP address and basic request details when the app fetches results. To stop abuse of sign-in codes we keep a keyed, irreversible hash of the IP address that requested a code, for at most 75 minutes; apart from that we do not store IP addresses ourselves. Our hosting provider (Cloudflare) may keep them briefly in infrastructure logs for security and reliability, as described in its own policy.

What we do not collect: phone number, contacts, precise location, photos, payment information or identity documents. Without an account, the name and birth date you enter for Personal and Zodiac numbers stay on your device and are never sent to us.

Advertising

LuckyNumberz is free and supported by advertisements delivered through Google AdMob. To show and measure ads, Google may collect your advertising ID, IP address, device type and similar information under the Google Privacy Policy (policies.google.com/privacy). You can reset or limit your advertising ID in your device settings (Android: Settings → Google → Ads; iOS: Settings → Privacy & Security → Tracking).

In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent before ads are shown. To change that choice, clear the app's data (or reinstall the app) so the question is asked again. On iOS, personalised ads are shown only if you allow Tracking.

The website luckynumberz.com also carries advertisements, delivered through Google AdSense. To show and measure them Google and its partners may set cookies in your browser and process your IP address, browser and device details, and the pages you view on this site, under the Google Privacy Policy (policies.google.com/privacy). Visitors in the European Economic Area, the United Kingdom and Switzerland are asked to consent before any of this happens, and may decline; you can change that choice at any time from the consent link on the site. Visitors in Türkiye (browsers set to the Türkiye time zone) are asked first by our own consent box: until you allow ads, the ad script and its cookies are not loaded at all, and you can change your choice from "Ad cookie settings" at the bottom of every page. Declining does not limit anything on the site — every result, archive page and statistic stays available.

Service providers

Cloudflare, Inc. — hosts our backend service and database (results, statistics, notification records).

Expo (650 Industries, Inc.) — relays push notifications to your device. Expo receives the push token and the message text, nothing else.

Google LLC — serves advertisements through AdMob and AdSense, as described above, delivers notifications to Android devices (Firebase Cloud Messaging), and verifies "Sign in with Google" identity tokens if you use that option.

Apple Inc. — delivers notifications to iOS devices (Apple Push Notification service) and verifies "Sign in with Apple" identity tokens if you use that option.

Resend, Inc. — delivers our sign-in code e-mails and, only with your consent, marketing e-mails. Resend receives your e-mail address and the message content.

All of these providers are based in the United States, so data is processed outside Türkiye. They process data on our behalf or under their own policies; we do not share data with anyone else, and we never sell it.

How long we keep data

The notification record (push token, chosen games and notification types, language, platform): When you turn notifications off in the app, the app asks our service to delete the record and it is deleted at once. If your phone is offline at that moment, or notification permission was already revoked in the system settings, the request cannot be sent; turn notifications on and off again in the app, or e-mail us. If you uninstall the app without turning notifications off first, the record is deleted when the notification service tells us, while sending a notification, that the device is no longer registered. This depends on the notification service and has no fixed time; to remove it right away, turn notifications off before uninstalling or e-mail us. Step-by-step instructions: luckynumberz.com/legal/delete-data

Account data is kept for as long as your account exists. Tap "Delete account" in the Profile tab and the account, its sessions, its synced document and any pending sign-in codes are deleted immediately. Sign-in codes and IP hashes are deleted automatically within 75 minutes. Signing out removes the session from our service and keeps the account; if your phone is offline when you sign out, the session is deleted automatically after 180 days without use, and in any case 365 days after it was created. Deleted data can remain for up to 30 days in our hosting provider’s automatic database recovery history (Cloudflare D1 Time Travel), which is used only to recover from a failure; after that it is gone.

Draw results and statistics are public information about lottery draws and contain no data about you.

Your rights

Depending on where you live (for example under the GDPR in Europe, the CCPA in California, or the KVKK in Türkiye) you may have the right to access, correct, delete or restrict the processing of data about you, and to complain to a supervisory authority.

If you have an account, you can see and change its data in the Profile tab and delete everything with "Delete account". For a copy of your data or any other request, e-mail us at luckyn0mberz@gmail.com from the address you signed in with. Without an account, the only record we could locate is the notification record for your device; disable notifications in the app or e-mail us from that device. We answer within 30 days. Users in Türkiye: the notice required by the KVKK, with the legal bases and your rights under it, is at luckynumberz.com/legal/kvkk/tr

Age

LuckyNumberz is intended for adults aged 18 or over. We do not knowingly collect data from anyone under 18. If you believe a minor has used the app, contact us and we will delete any related record.

About lottery information

Draw results are fetched from official or operator-published sources and are shown for information. The app is not affiliated with, endorsed by or operated by any lottery operator. Generated numbers are for entertainment and do not improve your odds. The app does not sell lottery tickets.

Changes to this policy

If we change what the app does with data, we will update this page and the effective date at the top. Material changes will also be announced inside the app.
