Not on this list
Virus scanning of uploaded files runs on our own servers, so no file leaves SmartDuke for it. Services a business connects itself, such as its own WhatsApp number, its own Stripe, PayPal, Razorpay or PayU account for its customers' payments, or its own AI key, work under the business's own agreement with them.
We tell account owners by email at least 30 days before adding or replacing a subprocessor, as set out in our Data Processing Agreement.
