Cumulizer
This is a Make OpenData.ch Hackday Bern 2013 Finance-themed project with a focus on analyzing personal shopping data. We have started by aggregating data available from the Cumulus purchase points program run by Migros, but would be interested in expanding the concept to Coop Superpunkt and others.
Fundamentally, we believe that the data we help to collect when we make purchases is relevant and useful to us as individual shoppers, and we want to try provoking popular action to aggregate this (anonymously) with others in our community. We want to learn some of what the shops are already learning about us - what, when and where we make our purchases. Since their data is not open, we need to liberate our personal data by uploading it to a shared repository.
Data
Right now any customer who takes part in the Cumulus program can access detailed data about their purchases in CSV format. This is an excellent initiative from Migros, but the web site is not very user friendly so we would want to automate this process to make it easier for users.
Right now here are the steps to collect your data:
- Log into the Cumulus program using your customer number and a password on a paper mail-out to create an M-Connect account if you have not already
- Under Mein Konto - Kassenbons you can browse and view details of your shopping receipts
- Browsing month-by-month, and for every page, you need to click Alle, and then Ausgewählte Kassenbons als Excel-Liste (csv) to download a file with the details for those shopping trips
- You are now ready to share your personal data with us.. details on next steps forthcoming
