Privacy Policy

The short version

PlainTally's calculators run entirely in your browser. There are no accounts, no logins, and no server that stores the numbers you type in. This page explains the few things that are outside our direct control: advertising cookies and the infrastructure that serves this site.

What we don't collect

We don't require or offer account creation. We don't ask for your name, email address, or any financial account information. Every calculator on this site does its math with JavaScript that runs on your device — the numbers you enter are never transmitted to us or stored anywhere.

Advertising cookies (Google AdSense)

This site shows ads served by Google AdSense. Google and its partners use cookies (including the DoubleClick/DART cookie) to serve ads based on your visits to this and other sites, and to measure ad performance. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet.

You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info. You can also block or delete cookies entirely through your browser's settings, though this may affect how ads and some site features display.

Infrastructure & logs (Cloudflare)

PlainTally is served through Cloudflare's network. Like most web infrastructure providers, Cloudflare may process standard technical data — such as IP address, browser type, and request timestamps — for security, performance, and abuse-prevention purposes. This is infrastructure-level logging, not something PlainTally itself collects or has access to for tracking individual visitors. See Cloudflare's privacy policy for details.

Analytics

We don't run any first-party analytics or visitor-tracking scripts on this site beyond what's described above for advertising.

Changes to this policy

If this policy changes, we'll update this page and revise the "last updated" date above.
