Affiliate Disclosure

Last updated: April 2026

As an Amazon Associate, DueDateLab earns from qualifying purchases.

This page explains how affiliate links work on DueDateLab, what we receive when you click one, and what we do not see.

What we participate in

DueDateLab is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Our Amazon tracking ID is duedatelab-20. When you click an affiliate link on our site and make a qualifying purchase on Amazon, DueDateLab may receive a small referral commission, at no additional cost to you.

How we choose what to feature

We only mention products that we consider relevant to the topic of the page. We do not feature a product solely because it pays a commission. Our calculators and articles remain the primary value of the site, and any product mention is intended as optional supplementary reading or supplies, never a substitute for medical, dietary, or developmental advice from a qualified clinician.

What data we receive

DueDateLab does not receive your order details or any personal purchase information. Amazon may provide aggregate referral reports, which can include the number of clicks our links generated, the kinds of items purchased, and the total commission. We never receive names, addresses, payment details, account information, or any data that could identify you personally.

How tracking works

When you click an affiliate link on DueDateLab, you leave our site and arrive on Amazon. From that point, Amazon's own cookies and tracking technologies apply, governed by Amazon's privacy practices. You can read Amazon's privacy notice at amazon.com/privacy. Affiliate clicks do not change how the calculators on DueDateLab handle your inputs. Calculator inputs continue to be processed in your browser and are not sent to DueDateLab.

How we mark affiliate links

Pages on DueDateLab that contain an affiliate link include a visible disclosure directly above or beside the link, in addition to the disclosure in our footer. Affiliate links carry the standard rel="sponsored nofollow noopener" attribute and open in a new tab so your DueDateLab session is preserved.

No medical claims through affiliate placements

Featured products are never positioned as treatment, diagnosis, prevention, or cure for any pregnancy or parenting condition. For health decisions, follow the guidance of your OB, midwife, pediatrician, or other licensed clinician.

Other programs

If DueDateLab joins additional affiliate programs in the future, this page will be updated with the new program names, their disclosure language, and any additional data-handling notes. The footer disclosure will be updated alongside.
