Privacy policy
Calculators run in your browser and do not need an account. This site does not currently set advertising cookies or load advertising scripts. The contact form is not connected to a mailbox, so a submission is not sent or stored. When ads are later enabled, you can use Google ad settings or the aboutads.info choices tool.

What this site collects now
The calculators run in your browser. They do not need an account. This site does not currently set advertising cookies. If you type numbers into a tool, those numbers stay on your device unless you copy them elsewhere.
Contact form
The contact form is not connected to a mailbox or a database. Submitting it does not send a message and does not store your name or email on our servers.
Advertising, cookies, and third-party vendors
This site does not currently load advertising scripts or advertising cookies. When advertising is enabled, ads may be served by Google AdSense and other display vendors. Those vendors may use cookies or similar technology to show ads, measure visits, limit how often you see an ad, and estimate a general location and device type.
You can review or adjust Google ad settings at adssettings.google.com. You can also use the industry opt-out tool at aboutads.info/choices.
Consent in the European Economic Area and the United Kingdom
Before personalized ads are shown to visitors in the EEA or the United Kingdom, a Google-certified consent management platform will be used to collect and record a choice. Until that platform is installed and advertising is turned on, no advertising cookie is set by this site for that purpose.
Hosting and logs
Whatever company hosts the site may keep ordinary server logs such as IP address, browser type, and the pages requested. We do not sell those logs.
Common questions
Does this site use advertising cookies right now?
No. The site does not currently load advertising scripts or set advertising cookies. A consent tool for the European Economic Area and the United Kingdom will be installed before personalized ads are shown there.
What happens to numbers I type into a calculator?
Those numbers stay on your device unless you copy them elsewhere. The tools do not require an account and do not send your entries to a login system.
What happens if I submit the contact form?
Nothing is sent. The form is not connected to a mailbox or a database, and you will see a short note that no message was sent.
How can I opt out of interest-based ads later?
When advertising is enabled, you can review Google ad settings at adssettings.google.com and use the industry choices tool at aboutads.info/choices.
