Stello

Terms of Service

Last updated: April 6, 2026

These Terms of Service (“Terms”) govern your access to and use of Stello (the “Service”), a software-as-a-service product operated by Thomas Mitchell, a sole proprietor based in Illinois, United States (“Stello,” “we,” “us,” or “our”).

By creating an account or otherwise using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. The Service

Stello helps small businesses request reviews from their customers. The owner of a business (“you”) provides Stello with the contact information of customers you have an existing service relationship with, and Stello sends those customers a short SMS asking about their experience. Customers who report a positive experience are directed to a public review platform (such as Google); customers who report a negative experience are directed to a private feedback form visible only to you.

2. Eligibility

You may use the Service only if all of the following are true:

  • You are at least 18 years old.
  • You operate or are authorized to act on behalf of a legitimate business.
  • You will only enter contact information for individuals from whom your business has an existing service relationship and who have provided appropriate consent to receive communications from your business (see Section 5).
  • You are not located in a jurisdiction subject to U.S. embargoes or otherwise prohibited from using U.S.-based services.

3. Your Account

You are responsible for the information you provide during account creation, for keeping your account credentials secure, and for all activity that occurs under your account. Notify us promptly at support@usestello.com if you suspect unauthorized use of your account.

4. Acceptable Use

You agree that you will not, and will not permit others to:

  • Use the Service to send messages to anyone who has not consented to receive communications from your business, or who has revoked such consent.
  • Send unsolicited marketing, promotional, or advertising messages, or any content prohibited by applicable law.
  • Use the Service to send messages on behalf of a business other than your own without that business's authorization.
  • Misrepresent your identity, your business, or your relationship to a customer.
  • Send messages that are harassing, threatening, defamatory, obscene, or unlawful.
  • Attempt to interfere with, disrupt, reverse engineer, or gain unauthorized access to the Service or its underlying infrastructure.
  • Use the Service in a manner that violates the Telephone Consumer Protection Act (TCPA), the CAN-SPAM Act, the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), or any other applicable law or regulation.
  • Resell, sublicense, or otherwise commercially exploit the Service without our express written permission.

We may suspend or terminate your account at any time, without notice, if we reasonably believe you have violated these Terms.

5. SMS Compliance and Consent

You are the legal sender of every SMS message sent through your Stello account. Stello provides the technical infrastructure but does not originate the messages and is not responsible for their content or for obtaining consent from recipients.

Before entering a customer's phone number into Stello, you must have a documented basis for contacting that customer by SMS. Examples of acceptable bases include:

  • The customer signed a service agreement or intake form that mentions SMS communication.
  • The customer verbally agreed to receive a follow-up message during your service interaction.
  • The customer provided their phone number for the purpose of receiving service updates from your business.

At each send, you must affirm via the in-app checkbox that you have such consent. If a recipient replies STOP, UNSUBSCRIBE, CANCEL, END, or QUIT, you must immediately cease sending messages to that recipient and remove them from any future sends.

Stello's separate SMS Terms & Acceptable Use page contains additional details that apply to all SMS messages sent through the Service.

6. Customer Data

“Customer Data” means the information you provide to Stello about your business and your customers, including names, phone numbers, email addresses, service descriptions, and the sentiment ratings and feedback your customers submit.

You retain ownership of all Customer Data. You grant Stello a worldwide, non-exclusive, royalty-free license to host, process, transmit, and display Customer Data solely for the purpose of providing the Service to you. We do not sell Customer Data, do not use it to train AI models, and do not share it with third parties except as described in our Privacy Policy.

You represent and warrant that you have the legal right to provide all Customer Data to Stello and that doing so does not violate any law, contract, or third-party right.

7. Subscriptions, Billing, and Refunds

Stello offers a Free plan and a paid Pro plan. Pro is billed monthly or annually in advance through Stripe. By subscribing to Pro, you authorize us (through Stripe) to charge the payment method you provide for the applicable fees, including any applicable taxes, on a recurring basis until you cancel.

You may cancel your Pro subscription at any time from the Billing page. Cancellation takes effect at the end of your current billing period; you will retain access to Pro features until that date. We do not offer prorated refunds for partial billing periods, except where required by law.

We may change pricing with at least thirty (30) days' notice. Price changes apply to billing periods beginning after the notice period.

8. Free Plan Limits

The Free plan limits you to ten (10) review requests per calendar month. Once you reach the limit, you will not be able to send additional review requests until the next month begins or you upgrade to Pro. We may change the Free plan limit with reasonable notice.

9. Termination

You may terminate your account at any time by contacting support@usestello.com. Upon termination, your access to the Service will end and your Customer Data will be deleted in accordance with the retention schedule in our Privacy Policy.

We may terminate or suspend your account immediately, with or without notice, if you violate these Terms, if your account is compromised, if we are required to do so by law, or if we discontinue the Service.

10. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. WE DISCLAIM ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS, OR THAT ANY MESSAGE SENT THROUGH THE SERVICE WILL BE DELIVERED.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL STELLO BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

12. Indemnification

You agree to indemnify, defend, and hold harmless Stello from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any law or third-party right, including the rights of any recipient of an SMS sent through the Service; or (d) any Customer Data you provide.

13. Governing Law and Disputes

These Terms are governed by the laws of the State of Illinois, United States, without regard to its conflict of laws principles. Any dispute arising out of or related to these Terms or the Service will be resolved exclusively in the state or federal courts located in Illinois, and you consent to the personal jurisdiction of those courts.

14. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by posting a notice in the Service at least seven (7) days before the changes take effect. Your continued use of the Service after changes take effect constitutes your acceptance of the updated Terms.

15. Miscellaneous

These Terms, together with our Privacy Policy and SMS Terms & Acceptable Use, constitute the entire agreement between you and Stello regarding the Service. If any provision of these Terms is found to be unenforceable, the remaining provisions will remain in full force and effect. Our failure to enforce any right or provision of these Terms is not a waiver of that right or provision. You may not assign or transfer these Terms without our prior written consent; we may assign these Terms freely. There are no third-party beneficiaries to these Terms.
