Tatzel Labs LLC · Client Portal

Terms of Service

Effective August 9, 2026 · Massachusetts, USA

These terms cover the Tatzel Labs client portal at portal.tatzel-labs.com. Using it — booking a time, following a share link, or signing in — means accepting them. How we handle your information is in the Privacy Policy.

1. What the portal is

A private working surface between Tatzel Labs LLC and its clients: scheduling, appointments, files, invoices and a work tracker. It is not a public service and there is no self-service sign-up. Access comes from us, either as an account or as a share link sent to you.

2. Text message reminders

If you book an appointment you may choose to receive one reminder by text instead of by email. Participation is optional, is never pre-selected, and applies only to the number you enter on the booking form.

Reply STOP to any message to opt out. That stops all future reminders to that number, on every booking, not only the one you replied about. Reply HELP for help, or email privacy@tatzel-labs.com.

Opting out of text messages does not cancel an appointment and does not stop the corresponding email, which remains the primary record of any booking.

3. Share links

A share link lets somebody without an account see the times we have open and book one. Treat it as private. Anyone holding the link can book against it and see the appointment it produced. Links expire, and we can withdraw one at any time — a withdrawn link stops working and says so rather than failing silently.

4. Appointments

Booking a time reserves it. Either side may move or cancel an appointment through the portal, and both sides are notified when that happens. A confirmation carries a calendar invitation; for video meetings it includes the join link, which should be treated as private for the same reason a share link is.

5. What you upload

You keep ownership of files and text you put into the portal. You grant us only the permission needed to store them, show them to the people entitled to see them, and back them up. Do not upload anything you do not have the right to share, and do not use the portal to store material you are legally required to keep somewhere specific.

6. Acceptable use

Do not attempt to reach another client's data, probe or disrupt the service, or use it to send unlawful or abusive material. Access is a working arrangement between us and may be withdrawn if it is misused.

7. Availability

We run this ourselves and keep it up, but it is provided "as is" and "as available," without warranties of any kind to the fullest extent permitted by law. We do not warrant that it will be uninterrupted or error-free. The portal is a convenience, not a system of record — keep your own copy of anything you cannot afford to lose.

8. Limitation of liability

To the fullest extent permitted by law, Tatzel Labs LLC is not liable for indirect, incidental, special or consequential damages, or for lost profits or data, arising from use of the portal. Nothing here limits liability that cannot be limited by law.

9. Governing law

These terms are governed by the laws of the Commonwealth of Massachusetts, without regard to conflict-of-law rules. Any dispute belongs in the state or federal courts of Massachusetts.

10. Changes

We may update these terms and will revise the effective date above. A change to the text messaging program applies to new bookings only — a booking keeps the terms its reader actually saw.
