How Recipients Receive SMS Messages
Calc+ Vault allows registered users to send end-to-end encrypted messages to any phone number. When a sender composes a message and manually enters a recipient's phone number inside the app, a single SMS notification is delivered containing a one-time secure link.
No bulk messaging. Every SMS is a deliberate, one-to-one action initiated by a human user. Recipients are never added to a list or subscribed to any recurring communications.
Sample Message
Every SMS sent from this number includes STOP opt-out instructions:
Opt-In Method — Web Form (Primary)
Recipients can proactively opt in to receive secure message notifications via the form at cloudstrategy.ai/join. The form collects the recipient's phone number and an explicit consent checkbox before submitting:
Upon submission, a confirmation SMS is sent immediately and the opt-in is recorded in a timestamped audit log with IP address.
Opt-In Method — Consent Gate (Secondary)
When a recipient opens a secure message link for the first time, a consent gate appears before any message content is decrypted or displayed. The gate requires an explicit tap to proceed:
No message content is revealed without this affirmative action. The consent gate is shown on every new message link received.
Opt-Out Instructions
Recipients can opt out at any time by replying STOP to any message from this number. No additional messages will be sent after an opt-out is received. Recipients can reply HELP for support contact information.
- Opt-out keywords: STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT
- Help keyword: HELP
- Opt-outs are honoured immediately — no further messages sent
Message Frequency
Message frequency varies. Recipients only receive an SMS when a registered Calc+ Vault user explicitly sends them a secure message. There are no scheduled, automated, or recurring messages. Most recipients receive fewer than 3 messages per month.
