Phone number verification and SMS opt-in

SimplyTalk sends exactly one kind of text message: a one-time verification code, and only when the person has just asked for it inside the app. This page documents that flow for carriers and for our users.

How a person opts in

There is no list to join and no way to be enrolled by someone else. The only path is the person entering their own number, on their own device, in the SimplyTalk app.

The user opens SimplyTalk and reaches the screen shown below.
The screen states plainly that a one-time code will be sent by SMS to confirm the number belongs to them, and that standard message and data rates may apply.
The user types their own phone number and taps Send code. That tap is the opt-in.
One SMS is sent, containing only the code.
The user types the code back into the app to finish.

Confirm your phone number

We will text you a 6-digit code to confirm this number is yours. It lets the people you already know find you on SimplyTalk. Message and data rates may apply.

[ +1 · phone number ] [ Send code ]

The block above quotes the consent wording of the in-app screen word for word, from PhoneIdentityView.swift, and names its two controls. It is a transcription, not a screenshot. STOP, HELP and START are answered by the SMS service, described below; they do not appear on this screen.

The only message we send

SimplyTalk: 123456 is your verification code. It expires in 10 minutes. If you did not request it, ignore this message. Reply STOP to opt out, HELP for help.

No marketing, no promotions, no newsletters, no recurring messages. A number receives a message only in the minutes after its owner requested one.

What we do with the number

It confirms the account belongs to a real, reachable person.
It lets someone the user already knows find them in the app.
It is never sold, rented or shared with third parties for their own purposes, and never used for marketing. It is passed to Twilio, through Supabase, for the sole purpose of delivering the verification code you asked for.

See the privacy policy for how the data is stored and how to have it deleted, and the terms of service for the messaging terms.
