Privacy Notice
Last updated 20 August 2026
chahua.us is a private website operated by the Chahua family in the United States. This notice explains what happens to information when you visit it. It is short because the site does very little.
Who is responsible
The Chahua family. Questions, requests, and complaints go to family@chahua.us.
What the site collects automatically
Like any website, chahua.us is served by a hosting provider whose servers record ordinary request data: the IP address the request came from, the date and time, the page requested, the referring page, and the browser's user-agent string. We use this only to understand whether and when a document reference number has been looked up.
What the site collects when you look up a reference number
The verification page at /v exists so that an organization holding one of our documents can confirm it is genuine. When a reference number is looked up, we record the number checked, whether it matched a record, the time, the referring page, and the browser's reported user agent, language, and time zone. We record this because each reference number is issued to exactly one organization, and a lookup we cannot account for is the signal this register was built to catch. Nothing recorded persists between visits or identifies you as an individual.
What the site does not do
chahua.us has no user accounts, no newsletter, no shopping cart, and no advertising. We do not use tracking pixels, advertising cookies, session recording, device fingerprinting, or any third-party analytics service. We do not sell, share, rent, or trade information about visitors, and we never will.
Fonts served by Google
This site loads its typefaces from Google Fonts. When your browser requests those files, your IP address is visible to Google in the ordinary course of serving them. We have no access to that request and receive nothing from Google about it. Google's handling of it is governed by Google's own privacy policy.
Where lookup records are kept
Lookup records are stored in a private spreadsheet held in a Google account controlled by our household. They are not published, and they are not shared with anyone outside the family except where disclosure is required by law or is necessary to pursue a claim arising from misuse of one of our documents.
How long we keep it
Lookup records are kept for as long as the corresponding document reference remains in use, plus twenty-four months. After that they are deleted.
What we never put on this site
Social Security numbers. Full dates of birth. Certificate or record numbers. Images or scans of any document. Home addresses. Minors' full names. Verification records show initials, document type, recipient, date, and conditions, and nothing that could be used to impersonate a member of our family.
Children
This site is not directed to children and asks nothing of them. We do not knowingly collect information from anyone under 13.
Your rights
If you are a California resident, the California Consumer Privacy Act as amended by the California Privacy Rights Act gives you the right to know what personal information is collected about you, to have it deleted, to have it corrected, and to opt out of its sale or sharing. We do not sell or share personal information, so there is nothing to opt out of. To exercise the other rights, write to family@chahua.us. We will not treat you differently for asking.
Security
Lookup records sit behind the ordinary access controls of the account that holds them. No system connected to the internet is perfectly secure, and we make no guarantee that it is.
Changes
We may revise this notice. The date at the top is the date of the current version, and we do not backdate it.
