Privacy policy

Last updated: August 9, 2026

Tank and Tail respects your privacy. This policy explains what information the site does and does not collect when you use our aquarium calculators.

The short version

The calculators run entirely in your browser. The numbers you type are used only to show your result on your own device. They are not sent to us, and we do not store them. You do not need an account to use any tool on the site.

Information we do not collect

We do not ask for your name, email or any personal detail to use the calculators. We do not build a profile of you, and we do not sell or share personal information, because we do not collect it in the first place.

Server logs

Like most websites, our hosting provider keeps standard access logs. These may record technical details such as your IP address, browser type and the pages you request. This information helps keep the site running and secure, and it is not used to identify you personally.

Cookies and analytics

At the time of writing, Tank and Tail does not set advertising cookies and does not run third party analytics. If we add analytics in the future, we will update this policy to describe what is collected and how you can opt out.

Third parties

The site is served by a third party hosting provider that processes requests so the pages can load. We do not pass your calculator inputs to any third party.

Your choices

Because we do not collect personal data through the calculators, there is nothing for us to update or delete on your behalf. You can browse the site without providing any personal information.

Children

Tank and Tail is a general interest hobby site and is not directed at children. We do not knowingly collect personal information from anyone.

Changes to this policy

We may update this policy as the site changes. The date at the top shows when it was last revised.
