PRIVACY · CURRENT RELEASE

A local calculation.
Optional exports.

NDtime’s own calculator code processes the starting shutter duration and entered filter strengths locally in your browser.

Calculator data

No photograph or camera connection is requested. The calculator does not submit inputs or results to an application server, analytics event or browser-storage record. Refreshing restores the example. Copy uses your browser clipboard after you choose it. Download creates a text file on your device.

Hosting and technical requests

Cloudflare Pages delivers these static pages. Website delivery and security can involve technical information including an IP address, requested URL, time and browser details under Cloudflare’s policies. This notice does not claim that using a public website creates no network records. Read Cloudflare’s privacy policy.

Advertising and analytics

This release does not load advertising, third-party analytics or optional tracking scripts. Publisher metadata and ads.txt identify the intended publisher account. They do not mean that this host has advertising approval, active ads, consent coverage, measured visitors or earnings. A later host-specific setup requires an updated notice before activating those services.

Email enquiries

yardfill.helpful594@aleeas.com is an existing shared portfolio alias also used by Yardfill. SimpleLogin forwards enquiries to the operator’s receiving mailbox. Sender details, messages and attachments pass through those email services. Include only information needed for the enquiry. Read SimpleLogin’s privacy policy.

Your choices

You can use the calculator without emailing or creating an export. To ask about an email you sent or records controlled by the operator, use the same alias. Hosting and email providers handle their own processing. Notice prepared 18 October 2026.
