Privacy

There is nothing to opt out of. This site sets no cookies, runs no analytics, loads nothing from a third party, and has no backend that could store anything about you.

In detail

Cookies
None. Not for preferences, not for analytics, not for anything. There is no banner because there is nothing to consent to.
Analytics
None. No Google Analytics, no Cloudflare Web Analytics, no self-hosted counter. The content security policy on every response is set to load scripts from this origin only, which is what makes that a structural fact rather than a policy statement.
Third-party requests
None. No web fonts, no CDN-hosted libraries, no embedded media, no social widgets, no advertising. The font stack is the one your device already has; the scripts are served from this domain.
Accounts
There is no login, no account and no user profile, because nothing on the site needs one.
Local storage
Not used. The calculators hold their state in memory for the life of the page and transmit nothing.

What your browser does send

The site is served by a hosting provider, and like any web server it receives the ordinary request information needed to deliver a response: your IP address, the URL requested, the user-agent string and a timestamp. That is inherent to HTTP rather than something added here, and it is retained by the provider under its own policy — not aggregated into a profile by this site, which has no facility to do so.

The on-site search runs entirely in your browser. The index is a static file fetched from this domain when you start typing, and your query is never transmitted anywhere: it is matched against the file locally, and the ?q= parameter in the address bar is read by the page rather than sent to a server.

If you email us

Writing to semseoueo@gmail.com means your address and message exist in an ordinary mailbox, and a correction you report may be described in the dataset version notes. Nothing else is done with it, and it is not added to any list — there is no list.

Downloads

The CSV files at /downloads/ are static files. Downloading one is an ordinary HTTP request and nothing more; nothing is logged against your session, because there is no session.

Changes

If this ever changes — if analytics is added, or a hosted font — it will be stated here and the content security policy will have to change with it, which is a visible edit in the site’s response headers. Until then, this page is the whole policy.
