Who runs it
This site is built and written by Paul Gunder, founder of Rocky Mountain Apps, which makes calculators and reference tools. He kept a saltwater pool himself for a couple of years, years ago, and that is the whole of the pool experience behind these pages. Nothing here rests on it. Each figure is either taken from a document that is named and linked where it is used, or computed on this site from figures that are, and the pages mark which is which.
What it's for
The calculators answer one pool's question at a time — how much to add, how much water it holds, where its balance sits — out of the readings you took, and they show the arithmetic rather than a verdict. The log is for the other half of the job: a dated column of tests, so a reading can be read as a direction of travel instead of a single number. Codes written for public pools turn up on these pages where they carry the most specific published figure for something, and every page that names one labels it as a code for public pools. No page here is a compliance check on anybody's pool, and none of it is medical or professional advice.
How it's paid for
Today the site sells nothing, carries no advertising and has no affiliate links in it. A printable pack of worksheets may be offered for sale later on, and advertising may appear on the pages later on. Either change would be recorded, with its date, on what changed.
What the site keeps
The calculators run in your browser, and what you type into one is written into the page address so a result can be bookmarked, printed or sent to someone. That means your entries travel with the link: anything that keeps URLs — your browser history, the copy of the link you paste somewhere, the request log of whoever serves the page — keeps them too.
The chemistry log works the other way round. Its pools and readings are kept in local storage, in this browser on this device; nothing about them goes into the page address, and the page makes no network request to store them. Clearing this site's data deletes them, which is why the log has an export button. What the site's host records, for that page and every other one, is the ordinary request log — your IP address, your browser and the page you asked for — alongside the page-view counting the privacy policy describes.
