Affiliate Disclosure
What this means
SleepCycle Calc 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. As an Amazon Associate, this site earns from qualifying purchases.
We may also participate in other affiliate programs with other retailers. Affiliate links may appear in our content, guides, and tool recommendations.
How affiliate links work
When you click an affiliate link on this site and make a qualifying purchase on the retailer's site, the retailer pays us a small commission. You pay the same price you would normally pay — the commission comes from the retailer, not from you.
Our promise to you
- We only recommend products we believe are genuinely helpful for better sleep.
- Affiliate relationships never influence our calculator results — the math is based purely on sleep cycles.
- Our content is independent; we do not write sponsored reviews disguised as editorial content.
