Why don't Zomato and Swiggy give me my customers' phone numbers?

Restaurants told India's competition regulator the apps hide customer numbers behind a temporary landline. Zomato's terms say you may use customer data only to fulfil the order.

• In the competition case, the restaurant body alleged 'data masking': restaurants get a temporary landline, not the customer's number.
• Zomato told the regulator it stopped sharing personal details in October 2018 after negative user feedback.
• Zomato's terms bar adding customer data to a list, reselling it or sending unsolicited marketing.
• The limits do not cover people who were already your customers or who give you their data directly and opt in.
• Orders on your own link give you the customer's details directly, so you can build your own list.
