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.
When you look up a receipt number (in the chat or in "Track my case")
- We check that receipt's status in USCIS's official system.
- We store the status and its history to keep it up to date and to calculate statistics.
- On GreenBro's public pages receipt numbers never appear in full: only their first characters, and only when many cases share them.
When you create an account and save cases ("Track my case")
- Your email address, to send you the sign-in link and alerts about your case.
- 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
- 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.
What we don't ask for
- We don't ask for your name, address, A-number, Social Security number or any document. 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 your case's status and history.
- To email you when your case changes, if you asked us to.
- To calculate statistics about the cases we follow, such as processing times, approvals and statuses. They are always published in aggregate, without identifying anyone.
- 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. |
| 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 | The receipt number you look up |
| Google (Gmail) | Sending the sign-in link and alerts | 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 |
We may also disclose information if a law or a competent authority requires it.
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 |
|---|---|
| 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 |
| A case you delete from "Track my case" | Permanently removed within 30 days |
| Sign-in links | Expire after 30 days |
The status and history of receipt numbers are kept separately for statistics, with no link to your account or email.
7. Your choices and rights
- Use the chat without an account.
- Delete a case from "Track my case".
- Stop alerts with the link in every email.
- Ask for a copy or the deletion of your data (account, email, saved cases and linked conversations) by writing to apps@weycop.com. We reply within 30 days.
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 email account holders before it takes effect.
