Privacy policy

Who we are

Big Mac Time Machine is operated by Afterwork Studios, LLC, the controller responsible for this site. "We" and "us" below mean that company. You can reach us at [email protected].

The short version

Big Mac Time Machine is a free static website. There are no accounts, no logins and no server that receives your inputs. Every calculation runs inside your own browser. We do not ask for, collect or store personal information about you.

Information we collect

Explorer inputs. The year, product, basket and income you enter are processed by JavaScript on your device. To make views shareable, the year, product and basket are written into the page URL. The income figure, and whether it is hourly or annual, is never written into the URL: it is saved only in your browser's local storage so it is remembered on your next visit, and a link you share shows the recipient their own income (or the default), not yours. Nothing is transmitted to us. Clearing your browser's site data removes it.

Accounts and contact details. None. There is no sign-up, newsletter or contact form.

Server logs. The site is served as static files by Cloudflare. Like any web host, Cloudflare processes standard technical request data (IP address, user agent, requested URL, timestamp) to deliver pages and protect against abuse. We do not use this data to identify individuals. Cloudflare's handling of it is governed by its own privacy policy.

Cookies and advertising

The Big Mac Time Machine itself sets no cookies and runs no analytics.

No advertising is currently served. If advertising is added in future, this page will be updated to describe which partners are involved and how to control personalised ads.

Children

The site is not directed at children under 13 and we knowingly collect no information from them.

Changes

Any change to this policy will be posted on this page with a new "last updated" date.
