All proactive messages are individually toggleable in your dashboard at app.askcalvin.ai/dashboard/settings.

3. How you opt in

Opt-in is web-based and explicit. There are two ways to enroll, both of which require you to enter your phone number on a public page on askcalvin.ai:

Option A: Direct sign-up on this page. Use the sign-up form above. Enter your phone number and email, check the consent box, and submit. You'll receive a welcome SMS at the number provided and a follow-up email with a link to connect your Google Calendar.

Option B: Apply for full Calvin access. Submit an application at https://askcalvin.ai/request-access. The form requires your phone number and includes the SMS-consent box. If accepted, you'll receive a welcome email confirming SMS program enrollment plus a one-click Google authorization link, and you complete setup at https://app.askcalvin.ai. Option B unlocks the full Calvin product (calendar, email, memory, briefings); Option A is SMS-only.

By submitting your phone number on the form above, or on askcalvin.ai/request-access, you agree to receive recurring SMS messages from AskCalvin at +1 (848) 285-5733. Message frequency varies (typically 5 to 30 messages per day for an active subscriber, fewer if you have disabled most proactive messages). Message and data rates may apply. Consent is not a condition of any purchase. Text STOP at any time to unsubscribe. Text HELP for help, or email hello@askcalvin.ai. See our Privacy Policy and Terms of Service.
