Privacy
Effective 8 October 2026
The Short Version
Psychrometry collects nothing about you. There is no account, no cookie, no analytics script, no advertising and no third-party code on the page. Every temperature, ratio and load is computed by the page itself, in your browser, and nothing you type or tap is sent to us or to anyone else.
Who Publishes It
Psychrometry is published by PaintedApp, LLC. Questions about this policy, or about anything the page does with your information, go to support@painted.app, and a person reads every message.
What the Page Does With Your Readings
When you set a dry-bulb, a second reading, an altitude or a process, the page writes those numbers into its own address (for example ?t=30&v=60 or ?z=1600) so that you can bookmark or share the view. They therefore appear in your browser history and in any link you choose to send. They never reach a server as data we keep: the address is read by your browser, and the page is the same file for every visitor.
An altitude is a number you type. The page never asks for your location and has no permission to read it.
What Is Stored on Your Device
After your first visit, the page keeps a copy of its own files (the page, its stylesheet, its script, its fonts and its icons) in your browser's cache storage, so that it opens and computes without a network connection. That copy holds no personal information. You can remove it at any time by clearing this site's data in your browser's settings. The page sets no cookies and uses no local storage.
The Host
The page is served by Vercel Inc. Like every web host, Vercel receives the technical details that any request carries, such as your IP address, your browser's name and the time, in order to deliver the page and protect it from abuse. We have not turned on any analytics or tracking product, and we do not use those details to identify or follow anyone. Vercel's own privacy policy governs what Vercel keeps.
Children
The page collects nothing from anyone, children included. Nothing about using it asks for a name, an email address or an age.
Your Requests
Because the page holds no personal information about you, there is nothing for us to give you, correct or delete. If you believe otherwise, or you have any other question, write to support@painted.app and we will answer.
Changes
If this policy changes, the new text will be published on this page with a new effective date at the top. A change that collects anything at all would be stated here before it took effect.
