A quieter kind of comparison.

Calculator information

The calculator runs in your browser. We do not send your balance, bill, contribution, or preferences to our catalog API. Your selections appear in your comparison URL so you can share or revisit it. A link you share reveals those selections to anyone who receives it.

Hosting and request logs

When hosted, the site’s infrastructure provider can process request information such as IP address, time, user agent, and URL for delivery and security. Because your preferences can be in the URL, infrastructure access logs may contain them. Avoid sharing a comparison link if you do not want its amounts visible. There are no advertising trackers or analytics scripts in this preview.

Cookies and storage

This build does not set advertising cookies or persist calculator values in local storage. The owner’s admin token stays in the current page’s memory and is sent only to authenticated administration endpoints.

Email alerts

Email alerts are not active in this preview. We do not collect email addresses or promise notifications. Before enabling alerts, we will publish the sender’s identity and contact details, the purpose of collection, consent and unsubscribe process, retention period, and the email service provider.

Provider websites

Following a source link takes you to another site whose privacy practices and terms apply. Source links open with no referrer, so the provider does not see which comparison page you came from.

Before a public launch

The operator’s legal identity, privacy contact, access/correction process, infrastructure providers, and retention practices must be finalized before this preview launches publicly. This notice describes the current build; it does not claim a completed legal compliance review.
