1. Program Description
Lumenix.ai (operated by Lumenix AI Ltd, UK company number 15711110, 86–90 Paul Street, London, England, EC2A 4NE) operates a transactional and support messaging program (the "Program") that delivers operational, conversational, and informational communications to subscribers who have provided express, channel-specific consent.
The Program covers three channels, and you can opt in to any combination of them independently:
- SMS — text messages delivered via Twilio.
- WhatsApp — messages delivered via the WhatsApp Business API (Twilio for WhatsApp).
- Voice calls — outbound support and onboarding telephone calls made by Lumenix.ai staff (or via Twilio Voice).
Topics for all three channels include:
- Responses to your support inquiries;
- Transactional notifications related to your account;
- Interactions with our AI agents;
- System and service updates relating to our AI and software solutions;
- Important announcements relating to your subscription or the Program itself.
2. How to Opt In
You opt in by completing the sign-up form at lumenix.ai/#sms-optin. The form contains three independent consent checkboxes — one for SMS, one for WhatsApp, and one for voice calls. You may tick any combination; consent for one channel is never bundled with another.
Opt-in for WhatsApp specifically requires that you tick the WhatsApp consent box (in line with the WhatsApp Business Messaging Policy). Opt-in for voice calls specifically requires that you tick the voice-call consent box.
By opting in to any channel, you confirm that you are the subscriber or customary user of the mobile number provided, you are at least 18 years old, and you agree to these Terms.
You may also confirm or re-confirm opt-in by replying YES, START, or SUBSCRIBE to a confirmation message we send you via the relevant channel.
3. SMS Messaging
SMS
Provider: Twilio Inc.
Frequency: recurring messages, approximately 1 msg/month.
Cost: Lumenix.ai does not charge you for receiving SMS. Standard message and data rates from your mobile carrier may apply.
Opt-out: reply STOP, END, QUIT, CANCEL, or UNSUBSCRIBE to any SMS we send. You will receive one final confirmation, after which all SMS communications will cease.
Help: reply HELP to any SMS to receive contact details.
Carriers: compatible with major UK, US, and international mobile carriers. Carriers are not liable for delayed or undelivered messages.
4. WhatsApp Messaging
Provider: Twilio for WhatsApp (delivered via the WhatsApp Business API operated by Meta Platforms Ireland Ltd).
Frequency: recurring messages, approximately 1 msg/month.
Cost: WhatsApp messages are delivered over your data connection. WhatsApp does not charge for receiving messages, but your mobile data plan may apply.
Message types: we send only the message templates approved by Meta for our account. We do not send messages outside of approved templates.
Opt-out: reply STOP in any WhatsApp message we send, or block our number from within WhatsApp. You will receive one final confirmation, after which all WhatsApp communications will cease.

Compliance: we operate this channel in line with the WhatsApp Business Messaging Policy and the WhatsApp Commerce Policy. We do not send unsolicited bulk messages.
5. Voice Calls
Voice
Provider: calls are placed by Lumenix.ai staff or via Twilio Voice on our behalf.
Frequency: approximately 1 call/month or fewer.
Cost: Lumenix.ai does not charge you for receiving calls. Standard call rates from your mobile or landline carrier may apply if you return our call.
Calling hours: we only place support or onboarding calls between 09:00 and 19:00 local time on weekdays. We do not place automated calls outside these hours.
UK Telephone Preference Service (TPS): we screen all UK call lists against the TPS register before dialling. If your number is registered on the TPS, we will not call you regardless of any consent you provide here, unless you have explicitly notified us in writing that you wish to be called despite your TPS registration.
Opt-out: tell our caller during any call that you no longer wish to receive calls, or email info@lumenix.ai with the subject line "STOP CALLS". Your number will be added to our internal Do-Not-Call list within 28 days.
Caller ID: our calls display a UK number associated with Lumenix AI Ltd; we do not spoof caller ID.
6. How to Opt Out
You can revoke consent for any channel at any time, independently of the others. Revoking SMS consent does not affect WhatsApp or voice consent, and vice versa.
- SMS — reply STOP/END/QUIT/CANCEL/UNSUBSCRIBE to any SMS.
- WhatsApp — reply STOP in any WhatsApp message, or block our number.
- Voice — tell the caller, or email info@lumenix.ai with subject "STOP CALLS".
