Privacy Policy
Revised: September 8, 2026
Unconverted inquiries: 90 days after last contact · CAA files: IRS retention rules · Privacy: [email protected]
This policy describes personal information processing associated with the TectonPro LLC website and ITIN application support services. TectonPro is the brand of TectonPro LLC. The Internal Revenue Service (IRS) decides ITIN applications; TectonPro LLC is an independent service provider. CAA status does not mean that the IRS approves or guarantees this privacy policy.

1. Scope and information categories
This policy covers browsing, inquiries and information involved in an engagement. Inquiries may include your name, contact details, application needs and correspondence. An ITIN application may require your date of birth, citizenship, address, passport or other eligible identity documents, Form W-7, relevant tax information, signatures, identity-review records and IRS notices, depending on the application and service scope. Provide only information needed for the service. Do not post complete identity documents, tax numbers or account information in public comments.
2. Purposes and necessary information
Relevant information is used to respond to inquiries, assess eligibility, prepare and check documents, verify identity and foreign status under CAA rules, submit to the IRS, follow up on an application, arrange selected document deliveries and meet record-retention and compliance-review obligations. Missing or inaccurate required information may affect the service or IRS processing. CAA retention requirements do not provide blanket authorization to use inquiry information for unrelated purposes.
3. Website features and browser storage
The website uses browser local storage to remember your language preference. You can clear it in your browser settings. The price questionnaire calculates an estimate within the page from your selections. The copy-account button writes the public contact account to your clipboard at your request.
When you use WeChat, LINE, email or meeting platforms, those providers also process information under their own policies.
4. Information intake and international processing
You may submit required documents through WeChat, LINE or email. Identity video interviews may use Tencent Meeting or Zoom. Confirm the recipient and document-delivery arrangements before sending information.
An ITIN application requires necessary information to be submitted to the IRS in the United States. CAA compliance reviews may require records to be made available to the IRS or other authorized authorities. Selected delivery services require necessary recipient and delivery information to be provided to carriers.
Mainland China interview records are stored in China. Records for U.S. and Taiwan clients are stored in the United States. Information involved in these international processing arrangements remains subject to the purposes and retention rules in this policy.
5. CAA record-retention period
IRS Publication 4520, page 24, requires relevant CAA application record copies to be retained for three full calendar years following the year an application is mailed to the IRS. For example, records for an application mailed in 2026 must be retained through December 31, 2029. Records may be paper or electronic copies and include applicable tax returns, Form W-7(COA), supporting or exception documents, intake/interview notes and IRS notices. This requirement concerns specified record copies: it does not require keeping an original passport and does not automatically apply to every inquiry, transaction or website log. Other applicable legal retention duties must also be observed.
6. Inquiry retention and information protection
Inquiry information that does not lead to an engagement is retained for 90 days after the last communication, then deleted or anonymized. It is not used for marketing or provided to third-party marketers.
If an inquiry becomes an engagement, information forming part of the CAA application file follows the IRS retention rule above, rather than the 90-day inquiry period.
Confirm the delivery method before sending identity documents. Do not submit a complete passport or tax number in public comments. IRS Publication 4557 provides official guidance on safeguarding taxpayer data.
7. Access, correction and deletion requests
Use the website contact channels to request access, correction or deletion, or to raise a privacy concern. Identify the relevant service and your request. Appropriate identity verification may be needed to avoid disclosure to another person; do not send full identity documents in an initial public message. Records that must be retained by law or under the CAA agreement cannot be deleted during the required period solely because deletion is requested. Other requests are handled subject to applicable law and the actual processing involved.
8. Contact and policy updates
For privacy matters, email [email protected] with the subject “Privacy,” briefly describing your request and the related inquiry or order. Do not attach a complete passport or tax number to your initial email.
You may also contact us through the published WeChat or LINE entries. Revisions will update the date on this page, and material changes will be notified as required.
