Tatzel Labs LLC · Client Portal

Text Message Program

Effective August 10, 2026 · Massachusetts, USA

This page describes every text message the Tatzel Labs client portal sends, who can receive one, and how consent is collected. It is published so that the program can be read in full by anyone — a client, a mobile carrier, or a reviewer — without needing an account or an invitation.

1. The program

2. How somebody opts in

On the booking form, after entering a name and email, the reader chooses how they would like to be reminded. The control is a menu offering three answers — Email me, Text me, and No thanks — and it starts on Email me. Nothing about a text is pre-selected, and leaving the form alone results in an email.

Choosing Text me does three things on screen: it reveals a field for a mobile number, it shows the notice below, and it presents a separate consent checkbox that starts unticked and must be ticked before the appointment can be booked by text. Declining to tick it does not block the booking — it means the reminder arrives by email instead. The checkbox carries this label, directly above the button that books the appointment:

I agree to receive text messages from Tatzel Labs LLC: one appointment reminder per booking, sent to the number above. Msg & data rates may apply. Reply STOP to cancel, HELP for help.

The wording above is not a summary of the notice — it is the notice, character for character. When somebody books, that sentence is stored verbatim on their appointment alongside the number they entered and the moment they chose, so the question “what did this person actually agree to?” has one answer that can be read years later without reference to anything else.

Links to this page, the Privacy Policy and the Terms of Service sit beside the notice, outside it. They are a way out of the disclosure, deliberately not part of the sentence being agreed to.

3. The other two ways a number is texted

Neither of these involves the form in section 2, and both rest on the same single basis: an existing client or contact gave us their mobile number in the course of our working relationship. Both are decided one person at a time and sent by hand — never a list, never a bulk send, and never a number obtained any other way. In each case the person sending it records that basis for that individual, with their user id and the date.

An invitation to book. We may send a single text with a link to our booking page so they can pick a time. At most one per person.

A reminder for an appointment we scheduled for them. Sometimes we book an appointment on somebody's behalf rather than asking them to fill in the form — agreed in a call, or in an email. Where we do, we may send them the same single reminder by text. It is the same one message per appointment described in section 5, and it is off unless it is deliberately turned on for that particular appointment.

Because that person never saw the checkbox in section 2, its wording is not stored against their appointment. Storing a sentence somebody was never shown would produce a record of a consent that did not happen, indistinguishable afterwards from one that did. What is recorded instead is the basis above, in exactly these words:

Tatzel Labs LLC scheduled this appointment for this person and is sending one appointment reminder by text to a number they gave in the course of an existing business relationship, for the purpose of contacting them about our work together. Msg & data rates may apply. Reply STOP to cancel, HELP for help.

An opt-out overrides the relationship. A number that has replied STOP is never texted again — invitation, reminder, or otherwise — whoever booked the appointment.

4. What the messages say

There are three, and these are the real ones:

5. How often

One message per appointment booked, plus at most one invitation per person when we ask them to book. Nothing is sent on a schedule of our choosing: every message is the consequence of an appointment that was made — by the person on the form, or by us for them as described in section 3. Cancellations, confirmations and rescheduling all go by email, because a single reminder is what the notice in section 2 promises and we do not send more than the words somebody read.

6. Stopping

Reply STOP to any message. That applies to your number across every future booking, not only the appointment you replied about, and it takes effect immediately. Reply HELP for help, or email privacy@tatzel-labs.com.

An opt-out is recorded against the number itself and kept indefinitely, because forgetting it is exactly how somebody who asked us to stop gets texted again. Any appointment still expecting a text quietly moves back to email — nothing is cancelled and nobody is dropped.

If you have stopped messages and want them back, email us. We do not offer a self-service way to re-subscribe a number, because phone numbers are recycled and the person holding one today is not necessarily the person who opted out.

7. Your information

We do not share or sell mobile numbers, opt-in information, or consent records to third parties or affiliates for their own marketing purposes. They are used only to deliver the reminder you asked for. Messages are carried by Twilio Inc. and the mobile networks, acting on our behalf.

The full account is in the Privacy Policy, which governs everything the portal holds.
