Privacy policy
GreenBro is an independent tool that helps you understand your USCIS case. We are not affiliated with USCIS or the U.S. government. This policy explains, in plain language, what information we receive, what we use it for, who we share it with and how long we keep it.
In short
- We don't sell your information or use it for advertising. We use no third-party analytics or trackers.
- You don't need an account to use the chat. If you create one, we only ask for your email.
- We automatically remove personal details you type in the chat (name, address, A-number and others) before storing them or sending them to our AI provider.
- We keep chat conversations for 120 days. After that we delete their content and keep only anonymous counts.
- You can ask us to delete your data at any time.
1. What information we receive
When you use the chat
- The messages you write, after personal details are removed (see section 2), and the assistant's replies.
- An anonymous conversation ID, kept in a cookie, so the assistant remembers what you talked about.
- Your IP address and browser type, to protect the service from abuse (for example, message limits per connection) and to measure use.
Receipt numbers
- We only use a receipt number you give us yourself. Before we check it, we ask you to confirm that it is your own case or that its applicant, petitioner or requester authorized you to check it. We cannot verify this ourselves, so we rely on your confirmation. We never look up receipt numbers you did not give us, nor any other receipt number, such as neighboring ones.
- We check a receipt number's status with USCIS only when you ask, to show it to you, and only after you give that confirmation.
- If you save a case and ask for alerts, we check that case's status regularly to email you when it changes. You can stop the alerts or delete the case at any time.
- When you give that confirmation, we record that you did: the date, the wording you confirmed and a coded version of the receipt number, not the number itself.
- We do not use case statuses for statistics, comparisons or any other analysis, and we do not publish them.
- When we check a case for you in the chat, we keep USCIS's answer for 30 days after the last check, so asking again soon is faster and does not need a new request to USCIS. Then it is deleted, unless you save the case in "Track my case", where it is kept while it is saved (section 6).
- You can ask the assistant at any time to delete a receipt number and everything we keep about it; it is done at once.
- Receipt numbers are kept on our own server, are shared with no one, and never appear in full on public pages or in our logs.
When you create an account and save cases ("Track my case")
- Your email address, to send you the sign-in link and the alerts you ask for.
- The receipt numbers you save, the category you choose and the nickname you give a case, if any.
- The date you signed up, and the IP address and browser you sign in from.
- A record of the alerts we send you and whether you chose to stop them.
When you visit the site
- Our server logs each visit (IP address, browser and page), like any website. We use these logs for security and to count total visits.
The PDF packet tool and the form filler
- Your files are processed only on your device and are never uploaded to our server. All we receive is a notice that a packet was built, to count how many are made; it contains nothing from your documents.
- The answers you type to fill out a form stay only on your device and are never sent to our server. If you choose to save your progress, it is kept encrypted with your password in your browser and deleted after 30 days without use. All we receive is an anonymous notice that a PDF was generated, to count them.
What we don't ask for
- We don't ask for your name, address, A-number, Social Security number or any document (the form filler asks for them only to fill out your form on your device). Please don't type them in the chat.
2. Automatic removal of personal details in the chat
Before we store a message or send it to our AI provider, we automatically remove:
- names (for example, the header of a pasted letter or the name fields of a myUSCIS file);
- postal addresses (we keep only the city and state);
- A-number, Social Security number, USCIS online account number, passport, I-94 and driver's license numbers;
- date of birth, phone numbers and email addresses.
We keep what the assistant needs to help you: the receipt number, the form, the dates and status of your case, and the city or office.
This removal catches the most common forms but cannot guarantee it finds everything, especially a name written inside a sentence. That is why we ask you not to share personal details.
3. How we use information
- To answer your questions and show you the status of the cases you ask about or save.
- To email you when a case you saved changes, if you asked for alerts.
- To improve the assistant and the service.
- To protect the service from abuse.
4. Who we share information with
We don't sell or rent your information. We only share it with the providers we need to run the service:
| Provider | Purpose | What it receives |
|---|---|---|
| OpenAI | Generating the assistant's replies | Your messages, already without the personal details in section 2, and the conversation's context. Under its business terms, OpenAI does not use this data to train its models. |
| OpenAI | Checking your civics practice answers | The answer you type. If you answer by voice, the recording is sent only to be turned into text; we do not keep it. |
| Brave Search and Tavily | Searching official information when the assistant needs it | Only the search words the assistant writes, not your messages or your details |
| USCIS | Checking a case's status, only at your request or for the alerts you asked for | Only the receipt number you give us |
| Google (Gmail) | Sending the sign-in link and the alerts you ask for | Your email address and the alert's content |
| PayPal | Receiving donations, if you choose to donate | Whatever you give PayPal on its own site; we don't see it |
- These providers may use your information only to provide their service to us, and they are bound to protect it under terms at least as protective as this policy.
- No third party may use or disclose your information, including de-identified, anonymized or pseudonymized data, for any reason without your active consent.
- We do not share de-identified or anonymous data with anyone. The anonymous counts we keep are only for running GreenBro.
- We may also disclose information if a law or a competent authority requires it.
Your choices about sharing
You decide what to share. You can use the chat without an account, an email or a receipt number. If you give us a receipt number, we can check that case with USCIS for you; the benefit is a clear answer in one place. A receipt number identifies a case, so share only your own or one you are authorized to check, and do not add other personal details.
5. Cookies and storage in your browser
We only use our own, necessary cookies. We use no advertising or third-party cookies.
| Cookie | Purpose | Duration |
|---|---|---|
gb_session_id | Keeping your chat conversation | 5 days |
gb-uacnwn | Keeping you signed in, if you created an account | 30 days |
greenbro-language | Remembering your language | 1 year |
gb-donation-request | Remembering whether you saw the donation note | 7 days |
Your browser also stores a few usage preferences (language, open menus, offers you closed). They are not sent anywhere.
6. How long we keep information
| Information | Period |
|---|---|
| A case checked in the chat (USCIS's answer) | 30 days after the last check, or at once if you ask the assistant to delete it |
| Chat conversation text, with IP and browser | 120 days. After that we delete the text, IP and browser; only the date and the general topic of the question remain, for anonymous statistics |
| Chat memory (what the assistant remembers of the conversation) | 24 hours without activity |
| Conversation shown when you return to the page (signed-in users) | 12 hours |
| Server logs (IP, browser, page) | 14 days |
| Account, email and saved cases | While your account is active. From November 26, 2026, an account with no sign-in for 12 months is deleted, with its saved cases and everything linked to it. Signing in keeps it. |
| A case you delete from "Track my case" | You can recover it for 30 days; then it is permanently deleted, with your confirmation for it |
| Your confirmation that a case is yours or that you are authorized | In the chat: 120 days. For a saved case: while the case is saved |
| Sign-in links | Expire after 30 days |
7. Your choices and rights
- Use the chat without an account.
- Delete a case from "Track my case", or ask the assistant to delete a receipt number and its data at once.
- Stop alerts with the link in every email.
- Ask for a copy or the permanent deletion of your data (account, email, saved cases and linked conversations) by writing to apps@weycop.com. We complete it within 30 days of your request and tell you when it is done.
- Delete your account from "Track my case" with "Delete my account": your account, your email, your saved cases and everything linked to them are deleted within 3 days. Signing in again before then cancels it. You can also write to us from the account's email.
If you live in California
Under the California Consumer Privacy Act (CCPA), you can ask to know what personal information we have about you, to get a copy, to correct it and to delete it. We do not sell or share personal information for advertising. We will not treat you differently for using these rights. To use them, write to us as described above.
8. Security
We protect information with encrypted connections (HTTPS), restricted access to our servers and databases, and limits against abusive use. No system is completely secure, but we work to keep your information protected.
9. If there is a data breach
If a breach affects your information, we will email you, if you have an account, and post a notice on the site, with what happened and what we are doing about it.
10. Children
GreenBro is not directed to children under 13, and we do not knowingly collect their information.
11. Changes to this policy
If we change this policy, we will post the new version on this page with its date. If the change is important, we will show you a plain-language summary of what changed and ask for your active consent before it applies to you. Account holders also get the summary by email. If you do not agree, you can delete your data as described in section 7.
12. If GreenBro changes owners
If Weycop or GreenBro is merged, sold or transferred to another company, we will tell you before your information is transferred. The new owner will have to follow this policy, and you can delete your data before the transfer.
