The nations set the consumer laws and the companies follow it; the most restrictive case is no unauthorised tracking, no unauthorised analytics, local warehousing. If your system can cope with the most restrictive case, you can tag the data with the jurisdictions (easy), and then enable tracking / analytics / shared warehouses for more complex data. It sounds like a reasonable startup idea to help manage this.
