Privacy Policy
RanNuGen Gold Star · Last updated 13 November 2026
RanNuGen Gold Star (“the app”) generates random lottery number sets and lets you keep a history of them. This policy explains what data the app handles, why, and the choices you have. The app is published by Serhan Gercek (“we”, “us”). You can contact us at support@gercek.app.
The short version
- You can use the app without an account. Then your tickets, settings and ranges stay on your device and are not sent to us.
- If you create an account (optional), we store your email address and the data you choose to sync so it is backed up and available on your other devices.
- There are no ads, no analytics and no tracking in the app, and we do not sell your data.
- You can delete your account and cloud data at any time in Settings → Account → Delete account.
What we collect
| Data | When | Why |
|---|---|---|
| Email address | Only if you create an account | To sign you in, confirm your account, send one-time codes and reset your password. |
| Password | Only if you sign up with a password | Stored only as a salted hash by our authentication provider; we cannot read it. |
| Generated tickets: game, numbers, time, mode, target draw | Only if you are signed in | To back up your history and sync it between your devices. |
| Results you enter by hand | Only if you are signed in | To check your tickets and sync them between your devices. |
| Settings and custom number ranges (theme, sound, haptics, volume, generation mode, spin time, ranges) | Only if you are signed in | To sync your preferences. Notification reminder settings stay on your device. |
| Technical data such as your IP address | Whenever the app contacts our servers | Needed to deliver the service and keep it secure. Our hosting providers process it in their logs. |
We do not ask for your name, phone number, location, contacts, photos or payment information, and we do not use advertising identifiers.
Data that stays on your device
Without an account, everything the app stores (tickets, results, settings, ranges) is kept only in your device’s local storage. Reminders for draw deadlines are scheduled locally on your device; we do not receive a push-notification token for them. Removing the app deletes this data.
Service providers
We use these providers to run the app. They process data on our behalf:
- Supabase – account authentication, the database that stores synced data, and the server functions that fetch official results and delete accounts.
- Resend – sending account emails (confirmation, sign-in and password-reset codes). It receives your email address and the message.
- Public lottery data – to show official Powerball results, our server (and, as a fallback, your device) requests public data from the New York State open-data portal (data.ny.gov). No personal data about you is sent in these requests beyond what any web request includes, such as your IP address when your device makes the request.
Data is transmitted over encrypted connections (HTTPS). Access to each account’s rows in the database is restricted so that you can only read and change your own data.
Legal bases (EEA/UK users)
We process your data to provide the service you asked for (contract), to keep the service secure and prevent abuse (legitimate interests), and, where required, with your consent, which you can withdraw by deleting your account.
Retention and deletion
We keep your account data until you delete your account. In Settings → Account → Delete account you can permanently delete your account and all cloud data (tickets, results, settings, ranges). Deletion takes effect immediately; copies may remain in our provider’s encrypted backups for a limited period before they are overwritten. Data stored only on your device is not affected and is removed when you uninstall the app. You can also email us to request deletion.
Your rights
Depending on where you live, you may have the right to access, correct, delete, export or restrict the use of your personal data, and to object to processing or lodge a complaint with your data-protection authority. To exercise these rights, use the in-app tools or contact support@gercek.app.
Children
The app relates to lotteries, which are restricted by age in most places. It is not directed at anyone under 18 and we do not knowingly collect data from children. If you believe a child has created an account, contact us and we will delete it.
Not affiliated with any lottery
The app is not connected to, affiliated with or endorsed by any official lottery or game operator or website. Game names are trademarks of their respective owners. Whether to play any numbers is your own decision and responsibility, and tickets must be bought directly from the official websites or authorised retailers.
Changes to this policy
If we change this policy, we will update the date above and, for significant changes, tell you in the app.
