Terms
What you agree to when you use Calendar Agreement, and what this closed beta does and does not promise. Last updated 24 August 2026.
This is a closed beta. Read this part first.
Calendar Agreement is not a finished product and is not open to the public. It is being tested by a small group of people who were invited directly. If you are reading this, you are almost certainly one of them, or you found the page from a link.
Everything in the beta will be deleted. When this moves to its permanent home, the accounts, the businesses, the bookings and the customer records created during the beta are destroyed rather than carried across. That is deliberate, it is planned, and it is not a failure. Do not use this beta as the only record of anything you would be upset to lose, and do not use it to schedule work you cannot reschedule by hand.
Real calendar invitations go to real people. This is the one part of the beta that is not contained. When a booking is confirmed, a genuine Google Calendar invitation is delivered to the customer, and that invitation is an ordinary calendar entry on their calendar from then on. Deleting your beta account does not un-send it. Treat anything that reaches a customer as real, because to them it is.
Things will break, features will change without warning, and the service may be unavailable at any time. That is what a beta is. If something breaks in a way that matters, write to privacy@tributarylabs.com.
Who you are agreeing with
These terms are between you and the team operating calendar.tributarylabs.com. A company is being formed to operate this service. When it exists, these terms move to it, this page is updated to name it, and the date at the top changes. We are saying so here rather than naming a company that does not exist yet.
There are two kinds of people here and it changes what these terms mean for you. An operator signs in with Google, connects a calendar and publishes a booking page. A customer books a time on an operator’s page and never signs in at all. If you are a customer, most of what follows does not apply to you, and the section on bookings being between you and the operator is the one to read.
Your account
You sign in with Google. You need a Google account, you must be old enough to hold one, and you must keep control of it. Anything done through your account is treated as done by you, so if you lose control of it, tell us at privacy@tributarylabs.com and revoke this app in your Google account permissions.
This service is not directed at children and we do not knowingly let anyone under 16 hold an account, which matches what the privacy policy says about data.
Bookings are between the operator and their customer
We are not a party to the appointment. When a customer books an operator, the agreement about what will be done, what it costs, when it happens and what the cancellation rules are is between those two people. Calendar Agreement schedules it and delivers the calendar invitation. It does not supply the service being booked, does not vouch for either side, and does not take payment.
So: if you are a customer and something goes wrong with the appointment itself, the operator is who you deal with. If you are an operator, the terms your customers agree to at booking time are yours, and so is the responsibility for them being lawful, accurate and something you can actually honour.
If you are an operator
You are responsible for:
- The accuracy of what your booking page says, including your services, prices shown, hours and your own terms.
- The personal data of your customers that passes through this service. You decide what to collect and why, and you deal with your customers’ requests about it. The privacy policy describes what happens to it here.
- Anyone you invite into your business on this service, and what they can see and do once they are in it.
- Complying with the law that applies to your business, which we make no judgement about.
Google Calendar
This service only works because you connect a Google Calendar, and your use of Google’s own products stays governed by your agreement with Google. Two consequences worth stating plainly.
We ask for the narrowest access that makes the product work, and the privacy policy lists each permission and what it is used for, in full. We can read when you are busy and write to the one calendar this app creates. We cannot read the contents of your other calendars.
You can disconnect at any time from your Google account permissions, and the service stops reading and writing immediately. Calendar entries already delivered stay where they were delivered, including on your customers’ calendars, because by then they are ordinary calendar entries and not ours to withdraw.
What you may not do
Do not use this service to:
- Break the law, or help somebody else break it.
- Send unsolicited invitations, or invite people into a business who have not agreed to be invited.
- Impersonate somebody else, or misrepresent who you are or what you are offering.
- Attack the service or the people using it: probing for holes, scraping, overwhelming it with traffic, or trying to reach data that is not yours.
- Resell or rebrand the service as your own.
We may suspend or remove an account that does any of this, and during a closed beta we may do so immediately and without notice, because the alternative is leaving other testers exposed.
What we do not promise
The service is provided as it is, with no warranty of any kind. We do not promise it will be available, that it will be free of faults, that it will keep your data safe from every possible failure, or that it is fit for any particular purpose. During the beta we specifically do not promise continuity: see the first section.
To the fullest extent the law allows, we are not liable for lost bookings, lost income, lost data or any indirect loss arising from using this service. Some places do not allow those limits to be excluded, and where that is true, this paragraph applies only as far as it lawfully can.
This is stronger language than a finished product would use, and it is honest rather than defensive: you are testing something unfinished at our invitation and at your own risk.
Ending it
You can leave whenever you like. Deleting your account is self-serve and the privacy policy describes exactly what it destroys and what it cannot reach. You can also simply disconnect Google and stop using it.
We can end it too. We may suspend or close an account that breaks these terms, and we may end the beta itself at any time. When the beta ends, beta data is deleted, which is what the first section says and is worth reading twice.
Changes to these terms
If these terms change we update the date at the top. Where a change is material, and the move to the new operating company will be one, we update this page before the change takes effect. During a beta this page will change more than a settled product’s would.
Governing law
No governing law is named yet, and that is deliberate rather than an oversight. The company that will operate this service does not exist yet, so naming a jurisdiction now would be picking one on behalf of an entity that has not been formed. This section is completed when the company is, in the same edit that names it above. If that matters to your decision to use the beta, the honest answer is that it should, and you should wait.
