The current SleepPrism approach to cookies, local storage, analytics, and advertising technologies.
Last reviewed: August 11, 2026
Current use
The current public-tool design does not require advertising cookies or an account. The calculator can operate without storing the time you enter on a server.
Essential technologies
Our hosting and security systems may use strictly necessary technologies to deliver the site, balance traffic, prevent abuse, or preserve a security choice. These are not used to build a health profile.
Future analytics or advertising
Non-essential analytics, personalization, or advertising technologies will not be activated in regions requiring prior consent until an appropriate consent mechanism is live. This page will list the provider, purpose, duration, and controls before activation.
Managing choices
Browser controls can remove or block stored data. When a consent manager is introduced, a persistent privacy link will let you revisit your choice.
