When's It Due is a static website. It does not set advertising cookies. It does use local storage and may load anonymous analytics scripts described below.

Local storage (similar to cookies)

Your list, reminder preferences, theme, browse favourites, and similar settings are stored in this browser so the site works when you come back. That is strictly necessary for the list. You can clear it via the browser, or export/replace the list in Settings.

Vercel Web Analytics and Speed Insights

We load Vercel Web Analytics for anonymous, cookieless page views, and Vercel Speed Insights to measure how quickly pages load. Neither is used for ads. If Vercel sets a technical cookie or similar identifier for Speed Insights, it is only for performance. You can block these scripts with browser privacy tools or by clearing site data.

Amazon

When you tap Buy on Amazon, Amazon UK may set its own cookies. Those are Amazon’s, not ours. Buy links may include our Associates tag.

Chrome extension

The extension stores a copy of your list in Chrome’s extension storage on this device. It does not set website cookies on other sites.
