Casium, Inc. and its affiliated law firm, Casium Legal, LLC, an Arizona-licensed Alternative Business Structure (together, “Casium,” “we,” “our,” or “us”), value your privacy. This Privacy Policy explains how we may collect and use Personal Information when you use our Services (each as defined below).

‍

When we use the term “Personal Information,” this means any information relating to an identified or identifiable individual. This includes Personal Information you provide or generate when you access or use our website currently located at www.casium.com and its subdomains (together with any third-party services available therein, the “Site”), our immigration and mobility platform (the "Platform"), or any other websites, products, or services we may offer from time to time (collectively, the “Services”).

This Privacy Policy applies to “Foreign Nationals” (employees, employee candidates, or dependents of our business customers, or individuals filing on their own behalf) who use our Platform to submit immigration-related information; “Authorized Users” (employees or contractors of our business customers) who use our Platform to administer immigration cases; visitors to the Site; prospective customers; and individuals who apply for employment or otherwise directly engage with Casium.

If you are a Foreign National, your employer or prospective employer (the "Organization") may have engaged Casium to help coordinate your immigration case. If that’s the case, the Organization has access to the immigration-related information you submit through the Platform. By using the Platform, you acknowledge that the Organization may view, use, and receive copies of your immigration case information in connection with your employment-based immigration matter.

We may update this Privacy Policy from time to time. If we make a material change, we will email you before it takes effect, with a plain-language summary of what changed. If you do not agree with the change, you can close your account before it takes effect (see “Deleting Your Data and Closing Your Account” below). Minor changes that do not affect your rights, such as correcting typos, take effect when posted, and we will revise the “Last Updated” date above.

Do not use our Services if you do not agree with our Privacy Policy.

Aggregated Data

We may also collect, create, and use aggregated data sets for our commercial purposes. These data sets may be derived from Personal Information, but they are not Personal Information because they cannot be reasonably linked back to a specific individual.

2. How We Use Personal Information

We may use the Personal Information we collect to serve the following purposes:

• to create your account and provide the Services to you;
• to prepare immigration petitions and applications on behalf of you or your sponsoring employer;
• to assess your eligibility for certain immigration benefits or programs;
• to coordinate your use of the Services with your designated immigration attorney;

How We Use Cookies

We and some of our third-party service providers collect and store some of the information described under “Personal Information We Collect Automatically” by using cookies and other similar technologies like pixels, tags, and web beacons (collectively, “Cookies”). Cookies are small strings of information that a website you visit transfers to your browser. Cookies can be used to track your internet activity, remember your preferences, or improve your user experience. Some cookies are necessary to operate a website, while others are not. You can decide if and how your device will accept cookies by configuring your browser settings (see below under “Your Privacy Choices” → “Cookies”). If you choose to reject cookies, you may not be able to use certain features of the Services.

We currently use the following types of third-party cookies:

• Analytics cookies, which help us analyze how you use the Services, including by tracking how you interact with the Services, which pages you visit, and errors you may encounter. Our third-party partner that sets analytics cookies on the Site and/or Platform is: PostHog, Inc.

‍

3. USCIS Receipt Numbers

When USCIS accepts an immigration filing, it assigns the filing a receipt number (for example, IOE0123456789). We treat receipt numbers as Personal Information and as personally identifiable information (PII). We protect them the same way we protect the rest of your immigration case file.

How we collect them. We get receipt numbers from the notices USCIS issues for your case, and from information that you, your Organization, or your Casium legal team enter in the Platform.

How we use them. We use your receipt number to check your case status with the official USCIS Case Status API, up to twice a day, until your case reaches a final decision. Our servers make these requests directly to USCIS. We use the results only to keep your Casium legal team informed and to keep your case up to date. We do not use receipt numbers for marketing, and we do not sell them or share them with anyone other than USCIS, except as described in this Privacy Policy.

How we store and protect them.

• Receipt numbers are stored with your case file in our database, in data centers in the United States, and are encrypted at rest.
• Status checks go to USCIS only over an encrypted (HTTPS) connection, using credentials USCIS issued to Casium. We store those credentials in a secure secrets store, never in our code.
• Only Casium staff working on your case and authorized users at your Organization can see your receipt number.
• When your case status changes, we send an alert with the receipt number and the new status to your Casium legal team through our internal messaging tool.
• Our system logs record internal reference numbers, not receipt numbers.
• We keep a record of each status change for as long as we keep your case file. We delete records of status checks that found no change after 90 days.

‍

4. How We Disclose Personal Information

We may disclose Personal Information to third parties as follows:

• to our vendors, agents, consultants, and other service providers who need access to your information to perform services on our behalf, such as cloud services, web hosting, data labeling, analytics, or marketing. Our service providers include providers of cloud hosting and storage, email and documents, product analytics, the AI models that power features in the Platform, workflow infrastructure, meeting transcription, and internal team messaging. A current list of our service providers is available on request at privacy@casium.com. Service providers may use your Personal Information only to perform services for us, and they are bound by contract to protect it.
• to third parties with whom we jointly offer products or services, only with your active consent;
• to our professional advisers, such as auditors, accountants, or lawyers;
• in connection with the change to the control or financial status of Casium, such as a merger, sale of our assets, financing, acquisition, or bankruptcy (see “Change of Ownership or Closure” below);
• to our current and future affiliate companies, only with your active consent;
• to protect the legal rights, safety, or security of Casium and our community, such as to enforce our legal agreements; to prevent fraudulent or unlawful activity; or to respond to a law enforcement or government authority request or other legal or regulatory process;
• as Aggregated Data, or as de-identified case summaries (see “De-identified Case Summaries” below); or
• to other parties at your direction or with your consent.

Apart from our service providers, the Organization sponsoring your immigration matter, and disclosures required by law, no third party may use or disclose your Personal Information without your active consent. This includes de-identified, anonymized, or pseudonymized data, except Aggregated Data and the de-identified case summaries we publish ourselves, described below. Any third party we share your Personal Information with under a contract is bound by that contract to protect it and to use it only for the purpose we shared it for.

‍

De-identified Case Summaries

We may publish short summaries of immigration cases we have handled, for example on our website. A summary may include the visa type, the month of the decision, the industry or type of employer, whether USCIS asked for more evidence, and how long the process took. Summaries never include your name, your employer’s name, receipt numbers, or other details that could reasonably identify you. If you would prefer that your case not be included, email privacy@casium.com and we will remove it.

‍

5. We Do Not Sell Your Personal Information

Casium does not sell your Personal Information, for profit or for any other monetary transaction.

‍

6. Your Privacy Choices

Your use of the Services is voluntary. You may decline to share certain information with us, or you may opt-out or withdraw your prior consent to share Personal Information with us (as set forth below); in such instances, we may not be able to provide you with some or all of the features and functionality of the Services.

Choosing what to share. Sharing complete information lets your attorney assess your options and prepare accurate filings. Holding information back may limit what we can do for you, or delay your matter. Once information is filed with a government agency, we cannot withdraw it from that agency.

• Emails: If you no longer wish to receive marketing emails from us, you can unsubscribe at any time by following the instructions in our marketing emails. Please note that even if you unsubscribe from marketing emails, you may still receive emails from us related to the Services, such as emails about changes to our policies or about purchases you’ve made from us.
• Cookies: Many web browsers enable cookies by default. Depending on where you are located, you may either need to opt-in or opt-out of our use of nonessential cookies. You can change your cookie settings or disable cookies at any time by updating your browser settings or, in the case of third-party cookies, by visiting the site of the third-party partners. For example, you can opt out of Google Analytics by visiting https://tools.google.com/dlpage/gaoptout or via Google’s Ad settings. You can find more information on how to opt-out of cookies at USA.gov.
• Do Not Track Signals: We do not currently recognize or respond to automated browser signals regarding tracking, such as “Do Not Track” signals.

‍

7. Children’s Privacy

We are committed to protecting the privacy of children. Individuals under 18 years of age are not permitted to use and/or submit their Personal Information through our Services. We do not knowingly collect Personal Information directly from individuals under the age of 18 (each a “minor”). However, we may collect Personal Information about minor dependents solely as necessary to process immigration filings, and only when such information is submitted by a party with appropriate authorization to do so. If you believe we might have any Personal Information from or about a minor without appropriate consent or authorization, please contact us at privacy@casium.com. If we become aware that we have collected Personal Information from a minor, we will delete the Personal Information in accordance with applicable law.

8. Job Applicants

If your Personal Information is submitted through our Site when applying for a position with Casium, the information will be used solely in connection with considering and acting upon your application. We may retain your Personal Information for a period of time, but only for the purpose of considering your application for current or future available positions. Your Personal Information may be shared with third-party service providers retained by us to collect, maintain, and analyze candidate submissions for job postings.

‍

9. Security

We take reasonable steps to protect your Personal Information from loss or unauthorized use, access, disclosure, or destruction. Even so, we can’t guarantee the complete security of any Personal Information you disclose online. For example, emails sent to or from our Services may not be secure, and so you should take care when considering what information you send to us via email. To the extent permitted under applicable law, we assume no liability or responsibility for the loss, disclosure, or destruction of your Personal Information due to errors in transmission, unauthorized access by third parties, or other causes beyond our control.

‍

10. Data Breaches

If a security breach affects your Personal Information, we will notify you without unreasonable delay, and no later than 30 days after we discover the breach. The notice will explain what happened, what information was involved, and any steps you can take to protect yourself.

‍

11. Retention

We retain your Personal Information for as long as necessary to fulfill the purposes for which it was collected, or for other essential purposes, such as complying with our legal obligations, resolving disputes, enforcing our agreements, or otherwise as required or permitted by law.

Some records, such as client files, must be kept for a set period under the laws and professional rules that apply to law firms. We keep those records only as long as required, and use them only for that purpose.

Dormant accounts. If your account has no sign-ins and no open immigration matter for 3 years, we will email you. If you do not respond within 30 days, we will delete or anonymize your Personal Information, except records we must keep.

‍

12. Deleting Your Data and Closing Your Account

Wherever you live, you can ask us to permanently delete your Personal Information or close your account.

• Email privacy@casium.com from the email address on your account, with the subject line “Deletion Request” or “Close My Account.”
• We will confirm your identity.
• We will complete your request within 45 days of confirming your identity, and email you when it is done.

We may keep records we are legally required to keep, as described under “Retention.” If an Organization set up your account, closing it does not close the Organization’s immigration case or delete the records the Organization holds.

‍

13. Change of Ownership or Closure

If Casium is involved in a merger, acquisition, sale of assets, or closure, we will notify you at least 30 days before your Personal Information is transferred. Any company that receives your Personal Information must follow this Privacy Policy. Before the transfer, you can download your data, or ask us to delete it as described above.

‍

14. Location of Personal Information

‍

Currently, we only use data centers located in the United States to store and process the Personal Information we collect; we have chosen this storage location to operate efficiently and improve performance. We take steps to process and protect Personal Information as described in this statement; however, the country where we store Personal Information may have laws that offer a different level of data protection than the country in which you reside.

‍

15. Additional Information for UK and EEA Residents

To exercise the above rights, please send an email to privacy@casium.com with the subject line “UK/EEA Privacy Request.” You also have the right to lodge a complaint with a supervisory authority, but we encourage you to first contact us with any questions or concerns.

We rely on different lawful bases for collecting and processing Personal Information about you, for example, with your consent and/or as necessary to provide the Services you use, operate our business, to meet our contractual and legal obligations, to protect the security of our systems and our customers, or to fulfill other legitimate interests.
