Privacy notice

Privacy at Cylinder Atlas

Effective and last reviewed: 2026-11-05. This notice describes the supplied implementation; the owner must update provider names and retention periods before a custom production launch.

Calculator data

Calculator inputs are processed in your browser. The site does not require an account and does not send dimensions to a database in the supplied build. Normal hosting infrastructure may still receive request metadata such as IP address, browser information, requested path and timestamp for security and reliability logs.

Contact messages

If the owner configures the contact endpoint, it receives name, email, message, a honeypot field, submission timing and request IP for validation and rate limiting. Valid messages are sent through the configured email provider to the site owner. The sender email is used as Reply-To. Do not include sensitive information.

Cookies and local storage

The supplied public calculators do not set analytics or advertising cookies and do not use local storage. The hosting platform may use essential security or access cookies for a private preview. If analytics, consent tools or advertising are added, this notice and any required consent interface must be updated first.

Advertising

Pages include clearly labelled layout reservations where advertising could be added later. No ad network is enabled in the source. If an owner activates an ad provider, that provider may process identifiers according to its own policy, and jurisdiction-appropriate consent may be required.

Sharing and retention

Contact data is shared only with the configured hosting and email providers as needed to deliver and protect the service. The owner should keep messages only as long as necessary to answer, maintain records or meet legal duties. This project does not sell personal information.

Your choices

You can use every calculator without submitting personal information. To request access, correction or deletion of a contact message, use the contact form and identify the message. The owner must insert a working privacy contact identity before public launch.

Changes

Material processing changes will be reflected here with a new review date. This page does not override rights available under applicable law.
