Affiliate disclosure

How PeriodFinder earns revenue

PeriodFinder is free to use, with no account and no paywall. When you click through to a brand's store and buy something, that brand or its affiliate network may pay us a commission. This is our revenue model; it funds the data verification work the site exists for.

As an Amazon Associate, PeriodFinder earns from qualifying purchases. Amazon links appear only as a second option, on brands that run no affiliate program of their own, and we never show Amazon prices or stock.

In line with FTC guidance, assume any link from this site to a retailer or brand store is an affiliate link. Affiliate links on this site carry a rel="sponsored" attribute, and every page carries the disclosure in its footer.

What it costs you

Nothing. The price you pay is the same whether you click through PeriodFinder or go to the brand directly. The commission comes out of the brand's marketing budget, not your pocket.

Why the data doesn't bend

The site's entire value is that the comparison is neutral, so the wall between revenue and data is structural:

• Size charts and absorbency figures come from each brand's published claims and are graded by the same A/B/C rules for every brand, affiliated or not - the methodology is public.
• Tool results are computed from that data in your browser; there is no mechanism for a paying brand to rank higher in a size or absorbency answer.
• Catalog ordering defaults to objective keys (closest coverage, data-quality grade, price) - never commission rate.
• Brands we have no affiliate relationship with appear in the data on equal footing, and brands with nothing in our live catalog (Proof, Bambody, Skims, Rael) keep their pages whether or not a link on them can earn.

Who pays us

The list below is generated from the same registry that builds every buy link, so it cannot drift from what the site actually does. Where a brand link is not yet part of a program, it is a plain link to the brand's own store; the comparison data is published either way, and the data grades never depend on who pays.

• The Period Company: a live affiliate program (code-based; the 10% off code is shown at buy moments). We earn a commission on purchases made through our links.
• Bambody: no program yet; a "Search Amazon" link appears as a second option and earns a small commission through Amazon Associates.
• Hanky Panky: no program yet; links go straight to the brand and earn nothing.
• Knix: no program yet; a "Search Amazon" link appears as a second option and earns a small commission through Amazon Associates.
• Modibodi: no program yet; links go straight to the brand and earn nothing.
• Proof (Proof by Always): no program yet; a "Search Amazon" link appears as a second option and earns a small commission through Amazon Associates.
• Rael: no program yet; a "Search Amazon" link appears as a second option and earns a small commission through Amazon Associates.
• Ruby Love: no program yet; links go straight to the brand and earn nothing.
• Saalt: no program yet; links go straight to the brand and earn nothing.
• Thinx: no program yet; a "Search Amazon" link appears as a second option and earns a small commission through Amazon Associates.
