Providing chat services: compliance and regulations

• Note that providing services via chat (in either integration scenario) underlies country-specific regulations your service needs to follow. This can involve details on the use of shortened-URLs (scam regulations), automated message generation (spam regulations), possibility for customers to opt-out of communications, privacy, data-security and retention. Breaking these regulations may result in your numbers being blacklisted or cancelled by Twilio or the mobile carriers without further notice.
• WhatsApp and SMS data residency is determined by Twilio, which currently hosts data centers primarily in the US.

Note that Luware does not provide any assistance in being compliant with local laws and regulations.
