Your choice about analytics

Tallybuy asks before it measures how the site is used. Declining changes nothing about the offers, their order or their prices.

  • Analytics with Google Analytics. Counts visits and page views so Tallybuy can see what is used. If you allow it, Google Ireland Limited sets cookies on your device and receives your usage data, which can be processed in the USA. If you decline, nothing is sent to Google. With your consent Tallybuy also counts for itself how often a product page is opened and a shop link is followed: plain totals per product, without cookies and without anything that identifies you.
