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:

John sent you a secure message. Tap to read (expires in 24h): https://cloudstrategy.ai/m/example123 Reply STOP to opt out.

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:

I agree to receive secure message notifications from Calc+ Vault (Cloud Strategy, Inc.) via SMS. Message frequency varies. Message & data rates may apply. Reply STOP to unsubscribe, HELP for support.

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:

🔒 Secure Message Someone sent you a private encrypted message via Calc+ Vault. By tapping "Read Message" you agree to receive secure message notifications from this contact via SMS. [ Read Message ] Reply STOP to any SMS to stop receiving messages. Reply HELP for support.

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.

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.
