Privacy Policy
Greencard to Citizen is made by Wuyu (wuyuXAI), an independent developer. This policy describes exactly what the app collects, why, and where it goes. If something here does not match how the app behaves, the app is wrong and I want to hear about it: wuyuxai@gmail.com.
There is no account
The app does not ask for your name, email address, phone number, date of birth, A-number, receipt number, passport number, or any other identity document. There is no sign-up and no login. You cannot create an account because there is no account system.
When you first open the app it generates a random identifier for the device. That identifier is a random string. It is not derived from your Apple Account, your phone number, your device serial number, or your advertising identifier.
What is sent to the server
Nothing here is sent unless you turn on Visa Bulletin notifications. Until you do, the app only downloads the published bulletin and does everything else on the phone.
| Data | Why | Kept |
|---|---|---|
| The random device identifier | To know which device to notify, and to remember that this device has paid. | Until you delete the app data. |
| An Apple push notification token | To deliver the notification. | Until you turn notifications off or delete the app. |
| Your app language | So the notification arrives in the language you read. The text is written on the server, because your phone may be asleep when the bulletin comes out. | Same as above. |
| Your priority date, preference category, country of chargeability, and which chart you follow | The notification says how far your date moved that month. Working that out means comparing your priority date against the new cutoff, and the comparison has to happen where the notification is written. | Same as above. |
Those four fields together say something about your immigration situation, so they are worth naming plainly rather than burying. They are stored next to the random device identifier and nothing else. There is no column in the database for a name, an email address, or an IP address, because the app never asks for them.
Turn Visa Bulletin notifications off and they stop being sent. The app still shows you the same numbers; it just works them out on the phone instead.
What never leaves your phone
- Your civics answers, scores, and which questions you got wrong.
- The date you filed Form N-400, if you enter it. It is used on the device to decide which version of the civics test applies to you.
- Your notification preferences.
- Your priority date, if you never turn on Visa Bulletin notifications.
What the app does not do
- No advertising, no advertising identifier, no ad networks.
- No analytics SDK, no crash reporting SDK, no third-party trackers of any kind.
- No selling, renting, or sharing of any data with anyone.
- No connection to your USCIS online account. The app never asks for your USCIS password and cannot sign in on your behalf.
- No case tracking. The app does not accept receipt numbers and never contacts USCIS about an individual case.
Who else sees anything
One party, and only because it has to be involved: Apple. Push notifications go through Apple Push Notification service. In-app purchases are handled entirely by Apple; I never see your payment details. Apple's privacy policy applies to those parts.
The Visa Bulletin itself is downloaded from the U.S. Department of State by my server, not by your phone, and the request carries nothing about you. The server runs on a virtual machine I rent in the United States. No other company processes your data.
Deleting your data
Turning off Visa Bulletin notifications removes the notification token and the priority date fields from the server. Deleting the app removes the random device identifier from the phone, which means the remaining record can no longer be linked to any device; those are cleaned up on a schedule.
You can also email wuyuxai@gmail.com and ask for everything to be deleted. You do not need an account to make that request, and you do not need to prove who you are, because I do not know who you are.
Children
The app is not directed at children under 13 and does not knowingly collect anything from them.
Changes
If this policy changes in a way that affects what is collected, the change appears here with a new date, and the app's release notes say so.
