I don't know how many of you know this company- Gokwik. They sit on the majority of checkouts on Indian D2C websites. I placed an order on Boat and gave them my number and address. And voila, it is present across all other D2C using the same checkout. And yesterday, I just browsed a company called Saada and someone from their team called me and emailed me. I never signed up for sharing my details, or at least didn't see any opt-out option. This is in the face of Data privacy and they have been funded for this Business model.
