YOUR REST, YOUR BUSINESS
Simple by design.
Private by default.
The Snoozely calculator runs in your browser. You do not need an account, and your sleep calculations are not sent to a Snoozely application server.
Saved preferences
If you select “Remember settings on this device,” your calculator settings are saved in your browser’s local storage. Uncheck it to remove the saved settings. Clearing site data also removes them. Saving is optional, and the calculator works without it.
Appearance
Snoozely follows your device’s light or dark appearance until you use the theme toggle. Your chosen appearance is saved in local storage so it stays consistent between visits. Clear site data to return to your device’s default.
Shared links
“Copy a link to this plan” puts your chosen mode, time and preferences in a link. Anyone you share it with can see those settings. Links may appear in browser history and hosting request logs. Opening a plan uses the next occurrence of the selected time; Sleep now and nap links calculate from the time they are opened.
Analytics
We use Google Analytics on snoozely.lol to understand website visits, popular pages and traffic sources. Google Analytics uses cookies and processes information such as browser and device details, approximate location and page visits. We exclude query strings and fragments from the page and referrer URLs we send, so shared sleep-plan settings are not included. We do not send calculator inputs or results, and advertising personalization and Google signals are disabled. Enhanced measurement is turned off.
You can block analytics with your browser’s privacy tools or use Google’s Analytics opt-out browser add-on. See Google’s privacy policy for details about its processing.
