About

The short version

Keirsdad is a small collection of productivity tools. They are built by one person. They work offline. They are designed to be useful and then get out of the way.

Why this exists

Most productivity software is built to maximise engagement — notifications, streaks that guilt you, dashboards full of metrics about your metrics. The tools get in the way of the work.

Keirsdad tools are built on a different assumption: the best tool is the one you barely notice. It should do what you need, hold your data safely, and never demand your attention.

How it is built

Each tool is a standalone web app that runs entirely in your browser. Data is stored in IndexedDB on your device. There is no server involved unless you opt into sync.

The sync layer uses Dexie Cloud for real-time data synchronisation. When sync is enabled, your data is encrypted in transit and stored on Dexie Cloud's servers. It is not end-to-end encrypted.

The tools are built with React, Tailwind CSS, and TypeScript. The website you are reading now is built with Next.js, and also runs the subscription checkout.

Privacy stance

What you put into the tools stays on your device unless you turn on sync. We do measure how the tools are used, with PostHog, and we monitor errors with Sentry, so we can find what is broken and what is useful. This website only loads Google Analytics if you accept cookies. Keirsdad is a trading name of Rabblepop Ltd.
