sms messaging

sign-in links: a one-time URL we text you after you tap "send magic link" in the app. tapping the link signs you in. links expire 24 hours after issue and can be used only once.

event invites: when a friend who already uses planet invites your phone number to an event, we send a one-time URL that opens the event. invite links expire 14 days after issue.

we do not send marketing, promotional, or recurring messages. every SMS is triggered by a specific user action.

low and bounded. a typical planet user receives fewer than five SMS messages per month — usually one sign-in link when they switch devices, plus the occasional event invite from a friend.

open the planet app, enter your phone number, and tap "send magic link". this is the only opt-in path for sign-in messages.

event invites are opt-in by virtue of someone you know choosing to invite your phone number to an event. you can reply STOP at any time to stop receiving them.

reply STOP to any planet SMS to unsubscribe immediately. you will not receive further sign-in links or event invites at that number.

you can also email the address below and the operator will remove your number by hand.

opting out of SMS does not delete your planet account. to delete the account itself, email the address below.

reply HELP to any planet SMS for a short auto-reply with contact information.

message and data rates may apply. planet does not charge you for SMS, but your mobile carrier may. check your plan if you are unsure.
