What this site stores, what it sends, and what it does not. Written to describe how the site works today, and updated when that changes.
Last updated
The short version
- No accounts and no sign-in.
- Your test results stay on your device. Nothing you measure is transmitted.
- The site currently loads no analytics, no advertising and no third-party scripts.
- A small amount of data is kept in your browser for your own convenience, listed below.
Why results cannot leave your device
The site is a set of static files. There is no application server and no database, so every test runs inside your browser on your own hardware. When you measure a refresh rate or record a verdict in the guided check, that information exists in your browser and nowhere else. This is a property of how the site is built rather than a policy decision, which is why it is stated first.
What is stored in your browser
Local storage, on your device only. It is never transmitted and no other site can read it.
| Key | What it holds | Why |
|---|---|---|
dp-theme | The word "light" or "dark" | So your theme choice survives a reload. |
dp-last-colour | A hex colour value | So the colour tool reopens on the colour you were using. |
dp-monitor-test | Your answers in the guided check | So you can stop part-way and come back without losing them. |
Clear it at any time through your browser's site data controls. The site works exactly as before with default settings. If your browser blocks storage, nothing breaks; the preferences simply do not persist.
Offline caching
A service worker stores a copy of the pages and code on your device so the tools keep working without a network connection. That is a cache of this site's own public files. It holds no personal information and sends nothing anywhere. Clearing site data removes it.
Server logs
The site is served by a web host, and like any web server it produces standard access logs containing the requested address, a timestamp, an IP address and a user agent string. That is the hosting provider's ordinary operation. No analytics layer sits on top of it and no profile is built from it.
Advertising
There is no advertising on the site today, and no advertising or analytics code is loaded. Advertising may be added in future to cover hosting costs. If it is, this page will be updated before it goes live, and the update will say plainly what the advertising partner receives, whether it sets cookies, and what choices you have. The changelog will record the date.
Whatever changes, one thing will not: the tests run on your device, and what you measure is not something this site collects or has any way to see.
Children
The site collects no personal information from anyone, of any age.
