Terms of Service

The terms governing access to and use of Tacet's services.

Last updated: September 2026 · Effective: February 2026

These Terms of Service (“Terms”) constitute a binding agreement between you (“Client,” “you,” or “your”) and Tacet, Inc. (“Tacet,” “we,” “our,” or “us”).

By accessing our website, authorizing data integrations, or engaging in a pilot or subscription service, you agree to be bound by these Terms.

1. The Service

Tacet provides an economic intelligence platform that analyzes transactional and related business data to calculate Forward CLV and related analytics and that, on your approval, carries out marketing actions through systems you connect (the “Service”).

Forward CLV is a predictive estimate of what a customer will contribute over the next 12 months, after product cost and expected returns, discounted to present value.

Tacet may provide the Service through:

  • Pilot engagements
  • Diagnostic analyses
  • Subscription access
  • Platform-based access

Specific service terms may be defined in a separate services agreement, pilot agreement, or order form.

2. License and Access

2.1 Limited License

Subject to these Terms and any applicable service agreement, Tacet grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your internal business purposes.

This license does not grant you ownership of the software or underlying technology.

2.2 Account and Data Access

To provide the Service, you may authorize Tacet to access certain business systems (such as your Shopify store, your Klaviyo account, or related data sources).

You represent and warrant that:

  • You have the legal right to provide such access
  • You have obtained any required permissions
  • The data provided does not violate applicable laws

By default, Tacet’s access to your ecommerce platform is read-only and is used for analysis.

In your email marketing platform, Tacet writes scores and related properties to customer profiles, records events on those profiles, and creates the lists and segments the Service uses. A flow you have built in your own account may act on those properties, lists, or events. That flow is yours and runs under your control.

Tacet does not send messages to your customers and does not create discounts except as set out in Section 2.3.

2.3 Actions Taken on Your Approval

Tacet may propose a specific marketing action (a “Play”). A proposed Play states its audience, its message, any offer, and its timing.

Tacet carries out a Play only after an administrator of your organization approves that Play in the Service (an “Approval”). Each Approval covers one Play, as shown to the administrator at the time of approval. Tacet personnel cannot give an Approval. A proposed Play that is not approved within seven (7) days expires.

After an Approval, Tacet may, through your own accounts and on your instruction:

  • Create, send, and cancel email campaigns, and create and run flows, in your Klaviyo account
  • Copy and edit your own email templates to prepare the message you approved
  • Load unique coupon codes into your Klaviyo account
  • Create discount codes in your Shopify store, only where you have separately granted Tacet the Shopify discount permission

Tacet creates discounts only within the limits you set in a written policy agreed with Tacet (the “Policy”), including maximum discount depth, one use per customer, expiry, and a ceiling on redemptions. Tacet does not change your prices, products, or orders.

Every send Tacet makes under an Approval excludes:

  • A persistent holdout group of your customers, which Tacet does not contact
  • A comparison group held back for that Play
  • Customers who do not have marketing consent recorded in your connected platforms

2.4 Pause, Undo, and Record

You may pause all Tacet actions at any time. You may cancel an approved send before it goes out, within the undo window set in your Policy. You may revoke Tacet’s access to a connected system at any time through that system.

Tacet keeps a permanent record of each Approval and of each action taken under it: who approved, what was approved, when, and what was sent.

3. Client Data

3.1 Ownership

You retain all ownership rights in your data, including transactional records, customer lists, and related business information (“Client Data”).

3.2 License to Tacet

You grant Tacet a limited, non-exclusive license to process Client Data solely to:

  • Provide the Service
  • Deliver analytics and reporting outputs
  • Carry out Plays you have approved under Section 2.3
  • Improve service performance using anonymized, aggregated data

Tacet does not sell Client Data.

Tacet does not contact your customers, except to carry out a Play you have approved under Section 2.3, through your own accounts.

Tacet does not use identifiable Client Data for its own advertising or marketing.

3.3 Roles

You are the controller of your customers’ personal data. Tacet processes that data as your processor, on your documented instructions. Your instructions are these Terms, any applicable service agreement, your Policy, and each Approval.

You are the sender of record for every message sent under an Approval. Those messages are sent from your own account, in your name.

3.4 Marketing Consent

You are responsible for obtaining and maintaining any consent required to send marketing messages to your customers. Tacet relies on the consent status held in your connected platforms, such as Klaviyo and Shopify, and does not verify it independently.

4. Intellectual Property

4.1 Tacet Technology

Tacet retains all rights, title, and interest in:

  • The Service
  • All software and source code
  • Algorithms and predictive models
  • Analytical methodologies
  • User interface designs
  • Documentation and related materials

These Terms grant you a right to use the Service, not ownership of Tacet technology.

You may not:

  • Reverse engineer the Service
  • Attempt to derive source code
  • Replicate Tacet’s models or methodologies
  • Resell or sublicense the Service

4.2 Output

Analytics outputs generated for you may be used internally for business decision-making.

You may not redistribute or commercially resell Tacet outputs without written permission.

5. Confidentiality

Each party agrees to treat non-public information disclosed by the other party as confidential.

Tacet will treat Client Data, revenue information, margin data, and related business information as confidential and will not disclose such information except:

  • As required by law
  • To provide the Service
  • To authorized personnel bound by confidentiality obligations

Confidentiality obligations survive termination of the relationship.

6. Data Security

Tacet implements commercially reasonable technical and organizational safeguards designed to protect Client Data from unauthorized access, disclosure, or misuse.

Additional details regarding data protection are available in our Privacy Policy and Data Processing Agreement where applicable.

7. Disclaimers

7.1 Predictive Nature of the Service

The Service provides predictive estimates and analytical models based on available data.

Forward CLV calculations and related outputs are estimates and do not constitute:

  • Accounting advice
  • Financial advice
  • Legal advice
  • Investment advice

You are solely responsible for business decisions made using the Service, including each decision to approve a Play.

7.2 No Warranty

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement.

Tacet does not guarantee specific business outcomes.

8. Limitation of Liability

To the maximum extent permitted by law:

Tacet shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits or business interruption.

Tacet’s total liability for any claim arising out of or relating to the Service shall not exceed the total fees paid by you to Tacet in the twelve (12) months preceding the event giving rise to the claim.

9. Indemnification

You agree to indemnify and hold harmless Tacet from any claims, damages, or liabilities arising from:

  • Your misuse of the Service
  • Your violation of these Terms
  • Your unlawful provision of Client Data

10. Termination

Unless otherwise specified in a separate agreement:

  • You may terminate access in accordance with your subscription terms
  • Tacet may suspend or terminate access if you materially breach these Terms

Upon termination:

  • Your access to the Service will cease
  • Data handling will be governed by the applicable service agreement and Privacy Policy

11. Governing Law

These Terms are governed by the laws of the State of Delaware, without regard to conflict of law principles.

Any disputes shall be resolved in the state or federal courts located in Delaware.

12. Changes to These Terms

Tacet may update these Terms from time to time. Updated versions will be posted on this page with a revised “Last Updated” date.

Continued use of the Service after changes become effective constitutes acceptance of the updated Terms.
