Terms of Service

These Terms of Service ("Terms") are a binding agreement between Stella Growth Intelligence ("Stella," "we," "us") and the individual or entity that uses the Service ("you," "Customer"). The Service is Stella's causal marketing-measurement platform and related websites, APIs, and integrations.

1. Acceptance of terms

By accessing or using the Service, creating an account, or connecting a third-party platform, you agree to these Terms and to our Privacy Policy. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization.

2. Description of service

Stella provides incrementality testing, geo holdout experiments, media mix modeling, multi-touch attribution, and related measurement and analytics. Measurement outputs are statistical estimates, not guarantees of outcomes, and should not be relied on as financial, legal, or investment advice (see Section 14).

3. Account registration and security

You must provide accurate information and keep your credentials confidential. You are responsible for activity under your account. Notify us promptly of any unauthorized use.

4. License grant and restrictions

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your internal business purposes. You may not: copy, modify, reverse engineer, or create derivative works of the Service; resell or sublicense it; use it to build a competing product; or access it to benchmark or for any unlawful purpose.

5. User responsibilities and acceptable use

You will not use the Service for fraudulent, illegal, infringing, or harmful activity; transmit spam or malware; harass or impersonate others; or interfere with the Service's operation or security. You are responsible for your data and your end users' data as described in Sections 6 and 8.

6. Connected platforms and third-party integrations

The Service connects to third-party advertising and e-commerce platforms (such as Meta, Google, Pinterest, Snapchat, TikTok, Shopify, and Amazon) through their APIs. By connecting a platform, you authorize Stella to access and process data from that platform on your behalf to provide the Service, including, where you enable it, sending conversion events back to that platform for your campaigns.

You represent and warrant that:

• you have the right to connect each platform account and to authorize Stella's access;
• you will comply with each platform's own terms, policies, and applicable laws;
• you have provided all required notices to, and obtained all required consents from, your end users for the collection, processing, and transmission of their data (including via Stella's tracking pixel and the sending of hashed identifiers to advertising platforms).

Your use of each platform is governed by that platform's terms; Stella is independent and is not endorsed by, affiliated with, or sponsored by these platforms, and is not responsible for their acts, omissions, availability, or changes to their APIs.

7. Fees, payment, and subscription terms

Paid plans are billed in advance on a recurring monthly or annual basis and renew automatically until cancelled. We will give at least 30 days' notice of price increases. Fees are non-refundable except as expressly stated or required by law. Late amounts may accrue interest at 1.5% per month or the maximum permitted by law. You authorize us and our payment processor to charge your payment method.

8. Data ownership and customer data

As between the parties, you own your Customer Data (the data you upload or connect, and data collected through your deployment of the Service). You grant Stella a limited, non-exclusive, royalty-free, worldwide license to host, process, and use Customer Data to provide and secure the Service, and to create aggregated and de-identified data that does not identify you or any individual. For Customer Data that includes personal information, you are the controller and Stella is the processor or service provider, as described in our Privacy Policy.

9. Intellectual property

Stella retains all rights in the Service, including its software, models, algorithms, and trademarks. No rights are granted except as expressly set out in these Terms.

10. Service availability

We aim for high availability but do not guarantee uninterrupted Service, and we may modify, suspend, or discontinue features. Third-party platform changes may affect functionality.

11. Data security and privacy

We maintain reasonable technical and organizational safeguards as described in our Privacy Policy, which is incorporated into these Terms.

12. Confidentiality

Each party will protect the other's non-public information disclosed in connection with the Service and use it only to perform under these Terms.

13. Free trial

We may offer a free trial (one per organization). We may change or end trials at any time. At the end of a trial, paid fees apply unless you cancel.

14. Warranties and disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. Measurement results are estimates and we do not warrant any specific business, revenue, or marketing outcome.

15. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, STELLA WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR LOST PROFITS OR REVENUE. STELLA'S TOTAL LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID IN THE 12 MONTHS BEFORE THE CLAIM, OR (B) ONE HUNDRED DOLLARS ($100).

16. Indemnification

You will indemnify and hold Stella harmless from claims arising out of your Customer Data, your use of the Service, your breach of these Terms, or your violation of a third-party platform's terms or of applicable law (including data-protection and consent requirements).

17. Termination and suspension

Either party may terminate for material breach not cured within 30 days. We may suspend or terminate immediately for illegal activity, fraud, security risk, or non-payment. On termination you have 30 days to export your Customer Data, after which we may delete it per our Privacy Policy.

18. Changes to terms and service

We may update these Terms by posting a revised version with a new "Last updated" date. Continued use after changes take effect constitutes acceptance.

19. Dispute resolution and governing law

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws rules. The state and federal courts located in Delaware have exclusive jurisdiction over disputes not subject to arbitration.

20. General

These Terms, with the Privacy Policy, are the entire agreement between the parties. If any provision is unenforceable, the rest remains in effect. We may assign these Terms in connection with a merger or sale of assets. Failure to enforce a provision is not a waiver.
