Privacy
This site has no accounts or forms, and it doesn't ask you for personal details.
Advertising
We show ads through Google Ad Manager and our advertising partner MagicBid. These services and their partners may use cookies or similar technology, your IP address and your device details to show and measure ads, including ads based on your interests.
You can manage personalised Google ads in Google Ads Settings, and you can block or delete cookies in your browser settings.
Server logs
Our web server keeps standard logs, such as IP address, browser and pages requested, for security and maintenance.
Unlocked checklists
If you choose to watch an optional ad for a checklist, your browser stores a note of which checklists you unlocked. It stays on your device.
Campaign links
If you arrive from an advertisement, the link may carry campaign details such as utm_source. We keep these on links between our pages so we can tell which campaigns are useful.
