SMS Opt-In
Sigma Synapses is committed to ensuring that all marketing SMS messages are sent only to users who have knowingly opted in to receive them. We maintain a transparent, consent-based process in line with industry and legal requirements.
How Users Opt In
On our sign-up and contact pages, next to the phone number field, we present a clear disclosure that customers must explicitly agree to before submitting their information:
"Yes, I agree to receive marketing updates and offers via SMS from Sigma Synapses at the phone number provided. Message and data rates may apply. Reply STOP to unsubscribe at any time."
We only send marketing SMS to phone numbers whose owners have knowingly given this consent.
Opting Out
Every SMS message includes clear instructions to unsubscribe, e.g., "Reply STOP to opt out."
Opt-out requests are processed immediately and users will no longer receive marketing SMS from us.
Record Keeping
For each opt-in we log and securely store the date and time of consent, the source of the opt-in, the phone number provided, and the exact consent language presented.
Message and data rates may apply. For full detail on how we handle SMS consent and your data, see our Privacy Policy.
