Privacy Policy
Last updated September 2026
The short version: This calculator doesn't collect, store, or send any of your data anywhere. Everything runs in your browser, and your settings stay on your device.
What this app does with your data
Nothing — because there's no server for it to send data to. Graphing Calculator is a single, self-contained page: your keystrokes, graphs, and calculations are all computed directly in your browser and never transmitted to us or anyone else.
What's stored on your device
Your Look, Zoom, and Layout choices, saved view presets, and Tutorial/Notebook progress are saved using your browser's built-in localStorage. This data stays on your device, is never sent to a server, and is only readable by this app. Clearing your browser's site data for mintyfreshapps.com will erase it.
"Share this state" links
The Share button encodes your current screen, functions, window, and variables directly into a URL. Nothing is uploaded — the link itself contains the data. It's only shared with whoever you choose to send that link to.
Cookies & third-party resources
This app itself does not set cookies. Loading the page does load two things from other companies' servers over HTTPS: fonts from Google Fonts, and the KaTeX math-rendering library from the jsDelivr CDN. Like any request to a website, these involve your browser sending its IP address and standard request headers to those services. We don't control what they do with that; see Google's and jsDelivr's own privacy policies.
Advertising
The one promotional item on this page — a small card for our own word game, Lexitaire — links to another MintyFreshApps site but doesn't track you or set any cookies here. This app doesn't currently show ads from any third-party ad network. If that changes (for example, by adding Google AdSense), we'll update this section to describe what data those ads collect and link to the relevant provider's privacy policy.
Children's privacy
This app is often used for school homework, including by students under 13. Since it doesn't collect any personal data from anyone, it doesn't knowingly collect data from children either — there's simply nothing here to collect.
Changes to this policy
If anything here changes — like adding ads or an account system — we'll update this page and the "Last updated" date above.
