Privacy
This page describes, accurately, what happens to information on this site. It is written to be true rather than long. Where a third party (Google) does collect data, that is stated plainly rather than glossed over.
The calculator: nothing is collected
The calculator runs entirely in your browser. The numbers you enter — savings, expenses, how you feel about your job — are processed on your own device by code running on the page. They are:
- not sent to this site’s server (there is no application server receiving them),
- not stored — not in a database, not in cookies, not in your browser’s local storage,
- not logged, shared, or sold.
When you close or reload the page, the inputs are gone. There is no account, no login, and nothing to delete, because nothing was kept. You can verify this: the page works with your network disconnected after it loads, because there is nothing for it to send.
Advertising: Google AdSense (this part does collect data)
This site shows display advertising through Google AdSense to cover its running costs. This is the part of the site that is not zero-data, and it would be dishonest to imply otherwise.
To serve and measure ads, Google and its partners:
- may set and read cookies or similar identifiers in your browser,
- may collect data such as your IP address, device and browser information, and your interaction with ads,
- may use this to show ads that are more relevant to you, and to limit how often you see the same ad.
This processing is done by Google, not by this site — the site owner does not receive your personal data from it and cannot see who you are. What Google collects and how it uses it is governed by Google’s own policies, which you can read at policies.google.com/technologies/ads and policies.google.com/privacy.
Your choices
- You can manage or opt out of personalised advertising at myadcenter.google.com and www.aboutads.info.
- Depending on where you live (for example the EU/UK or California), you may have additional rights over this data, and you may see a consent prompt before non-essential cookies are set. Where such a prompt is shown, ad cookies are set according to your choice in it.
- Most browsers also let you block or delete cookies directly in their settings.
Analytics
This site does not use Google Analytics or behavioural tracking analytics. If a privacy-light, cookie-free measurement tool is ever added, this section will be updated to name it and say exactly what it counts. As of the date below, there is none.
What this site’s owner can and cannot see
The site owner cannot see your calculator inputs, identify you, or track you across pages — none of that is collected. Standard web-server request logs (the kind almost every website’s host keeps automatically, such as IP address and page requested) may exist at the hosting-provider level for security and operation; these are not used to build profiles and are not combined with anything from the calculator.
Children
This site is intended for adults making decisions about their own working lives. It is not directed at children and does not knowingly collect information from them.
Changes
If what the site does with data changes, this page changes with it, and the date below is updated. Material changes will be reflected here rather than made quietly.
Contact
Questions about this policy can be sent to the site owner at the contact address published on the site.
