# Privacy Policy

Canonical: https://halfonadouble.com/privacy
Data through: 2026-10-02 close
Publisher: Half on a Double

_Last updated_: September 12, 2026

This policy explains what information halfonadouble.com (the "Site")
collects about visitors and how it is used. The Site has no user accounts,
no login, no comment system and no contact forms, so the information
involved is limited to what your browser sends when it loads a page.

## What is collected

**Usage data.** When you visit, the Site's hosting and analytics providers
record standard technical information: your IP address, browser type and
version, device type, operating system, the pages you visit, the referring
page, and the date and time of each request. This is used to understand
which pages are read, to keep the Site running, and to detect abuse.

**Chart data requests.** The interactive chart fetches per-ticker data files
from `data.halfonadouble.com`. Those requests are logged by the content
delivery network and storage provider in the same way as page views.

The Site does not collect names, email addresses or payment details.

## Third-party services

- **Cloudflare** hosts the Site and its data files, provides the content
  delivery network, and runs privacy-focused web analytics that do not use
  cookies or track visitors across sites.
  [Cloudflare privacy policy](https://www.cloudflare.com/privacypolicy/).
- **Google Analytics 4** is used to measure traffic. Google sets cookies to
  distinguish visitors and may process data in the United States.
  [How Google uses data from sites that use its services](https://policies.google.com/technologies/partner-sites).
- **Backblaze** stores the data files served through `data.halfonadouble.com`.
  [Backblaze privacy notice](https://www.backblaze.com/company/policy/privacy).

## Cookies

The Site itself sets only a preference cookie for light or dark mode.
Google Analytics sets its own cookies (typically `_ga` and `_ga_*`) to
count visitors. You can block or delete cookies in your browser settings;
the Site works without them.

## Advertising

The Site does not currently display advertising. If advertising is added,
this policy will be updated before it goes live to name the advertising
partners, describe the cookies and identifiers they use, and explain how to
opt out of personalised ads.

## Your choices and rights

You can prevent analytics collection with a browser extension such as the
[Google Analytics opt-out add-on](https://tools.google.com/dlpage/gaoptout)
or a content blocker. Depending on where you live, you may have the right
to ask what personal data is held about you and to have it corrected or
deleted. Because the Site does not identify visitors, such requests can
normally be met only by the analytics providers themselves, but you are
welcome to ask through the [contact page](/contact).

## Children

The Site is not directed at children under 13 and does not knowingly
collect information from them.

## Links to other sites

The Site links to third-party websites whose privacy practices are their
own. Read their policies before providing them with any information.

## Changes

This policy may be updated from time to time. The date at the top shows the
current version.
