Terms of Service

Last updated: March 10, 2026

These Terms of Service, as amended from time to time ("Terms"), constitute a legally binding agreement between SheetEngine, Inc. ("us", "our", "we", "Company") and the user accepting these Terms ("Customer"). These Terms govern access to and use of the SheetEngine platform available at sheetengine.app and any related services (the "Platform" and "Website"), provided on a Software-as-a-Service model with credit-based usage billing.

Use of the Platform constitutes acceptance of these Terms. If a User accepts the Terms on behalf of another entity, that User must have authority to do so. The Platform may also be subject to additional guidelines posted on the Website, including our Pricing page, Privacy Policy, and Acceptable Use Policy, all of which are incorporated by reference.

Note: These Terms contain a dispute resolution and arbitration provision, including a class action waiver, that affects your legal rights. You may opt out of binding individual arbitration as described below.

1. Right to access and use

Subject to Customer's compliance with these Terms and maintenance of sufficient credit balance or active Subscription, Company grants Customer and its Users a limited, non-exclusive, non-transferable right to access and use the Platform in accordance with applicable documentation, solely for Customer's internal business use.

The Company may update, change, or discontinue any part of the Platform at any time, including AI models, features, and integrations, with or without notice. We will make reasonable efforts to notify Customers of material changes in advance where practicable.

2. Credits and usage limits

Use of AI chat features consumes credits from Customer's balance based on token usage (input and output tokens) and the AI model used. Credit rates are published on the Pricing page. Deploys, file edits, project creation, and code review do not consume credits. The Company may change credit rates and usage limits from time to time with reasonable notice.

3. Trial credits and pre-released services

The Company may offer starting balances or trial credits ("Trial Credits") and alpha or beta features ("Pre-Released Services"). Trial Credits and Pre-Released Services are provided at Company's sole discretion and may be modified or discontinued at any time without liability. Pre-Released Services are made available on an "as-is" and "as-available" basis with no warranties of any kind, and Company's aggregate liability for claims arising from them shall not exceed US $100.

4. Accounts and customer obligations

To use the Platform, Customer registers via Google OAuth sign-in. Users must be at least 13 years old (16 within the EU) or the minimum age required in their jurisdiction. Customer shall: (a) not allow unauthorized individuals to access the Account; (b) not register via automated means; (c) keep all credentials secure; (d) ensure login details are not shared between individuals; and (e) promptly notify the Company of any unauthorized access.

Customer is responsible for all acts and omissions of its Users and their compliance with these Terms. Customer must provide reasonable cooperation with the Company in relation to these Terms.

5. Google account and infrastructure responsibility

Customer is solely responsible for obtaining and maintaining all Google Workspace configurations, credentials, and API access necessary to use the Platform, including the Google Apps Script API, Google Drive access, and Google Sheets. SheetEngine deploys code directly to Customer's bound Google Apps Script projects using OAuth credentials Customer grants at sign-in.

Customer is also responsible for the security and compliance of Customer-managed Google Sheets and Apps Script projects, for reviewing all deployed code, and for maintaining independent backups of Customer data.

6. Google OAuth registration

By registering via Google SSO, Customer represents that it is entitled to grant the Company access to the relevant Google account, including Drive, Sheets, and Apps Script scopes, without breach of any Google terms. Customer may revoke SheetEngine's Google account access at any time via Google Account settings.

7. Customer data

While using the Platform, Customer may upload or transfer data, including prompt text, script files, and configuration data ("Customer Data"). All rights in Customer Data remain with Customer.

SheetEngine does not access, read, or store the content of Customer's Google Sheets cells or spreadsheet data. SheetEngine's access is limited to reading and writing Apps Script project files (.gs, .html, appsscript.json) bound to Customer's sheets.

Customer grants the Company a non-exclusive, worldwide, royalty-free license to access, process, and store Customer Data solely as necessary to provide and maintain the Platform and to comply with legal obligations. This license terminates when Customer Data is deleted or the account is closed, subject to the Company's standard data retention obligations.

Customer represents and warrants that: (i) it has all necessary rights to share Customer Data with the Platform without infringing any third party's rights; (ii) Customer Data does not violate any applicable laws; and (iii) no sensitive data (such as health information, payment card data, or government ID numbers) will be shared without prior express written agreement with the Company.

8. Intellectual property

All right, title, and interest in the Platform, Website, and Company documentation - including software, code, design, text, logos, and trademarks (excluding Customer Data and Generated Output) - are the sole property of the Company and its licensors.

As between the Company and Customer, Customer owns all rights in the Apps Script code, HTML files, and related scripts generated by the Platform ("Generated Output") resulting from Customer's prompts or Input Data. The Company relinquishes all rights, title, and interests it might have in the Generated Output, without making any representation or warranty as to the nature of such rights.

Customer acknowledges that due to the nature of AI, Generated Output may not be unique and other users may receive similar output. Customer is solely responsible for reviewing, testing, and validating all Generated Output before deploying it to production environments.

9. Acceptable use

Customer and its Users may not, and may not aid others to:

  • Use the Platform in violation of these Terms or our Acceptable Use Policy.
  • Copy, modify, or create derivative works of the Platform or Company documentation (other than Generated Output).
  • Sell, sublicense, rent, or otherwise transfer Platform rights to any third party.
  • Reverse engineer, decompile, or extract source code from the Platform.
  • Use the Platform to build, train, or improve a competing product or service.
  • Create multiple accounts to circumvent credit limits or usage restrictions.
  • Access the Platform via automated means other than through the provided interface or official API.
  • Upload malicious code or take any action that interferes with the integrity or proper working of the Platform.
  • Remove or alter any copyright notices, trademarks, or proprietary rights notices.
  • Use the Platform to send unsolicited or unauthorized communications.
  • Use the Platform in high-risk or safety-critical environments (aviation, healthcare, nuclear, weapons, etc.) where failure could lead to severe harm.
  • Use Generated Output to provide regulated professional services (legal, medical, financial advice) without the required license or permit.

The Company may collect and use anonymous, non-identifiable usage data to maintain, improve, and market the Platform.

10. Feedback

Customer may provide design or functional feedback, suggestions, or comments regarding the Platform ("Feedback"). Customer assigns to the Company all rights in the Feedback. Feedback is not considered Customer Data or Confidential Information, and the Company may use it for any purpose without restriction or compensation.

11. Privacy

Use of the Website and Platform is governed by the Company's Privacy Policy, as amended from time to time. If the Company processes personal data as defined under applicable law, and to the extent required by law, the parties will enter into a Data Processing Agreement (DPA) regarding such data.

12. Copyright

If you believe your copyright or other intellectual property right is being infringed by a user of the Platform, please provide written notice to: compliance@sheetengine.app.

Your written notice must:

  • Contain your physical or electronic signature.
  • Identify the copyrighted work alleged to have been infringed.
  • Identify the allegedly infringing material in sufficient detail to allow us to locate it.
  • Contain adequate contact information (postal address, telephone number, and email address).
  • Contain a good faith belief statement that the use is not authorized by the owner, the owner's agent, or the law.
  • Contain a statement that the information is accurate and, under penalty of perjury, that you are authorized to act on behalf of the rights owner.

13. Third-party services and Google integrations

The Platform integrates with third-party software, products, and services, including Google Drive, Google Sheets, Google Apps Script, and AI model providers, accessible via API ("Third-Party Services"). Each Third-Party Service is subject to its own terms and conditions. The Company does not endorse and shall not be responsible or liable for any Third-Party Service. The Company may replace Third-Party Services at its discretion.

Google Services. Customer's use of the Platform requires OAuth access to Google Drive, Google Sheets, and Google Apps Script. Customer's Google account data is subject to Google's Terms of Service and Privacy Policy. SheetEngine's access is limited to the scopes Customer explicitly authorizes at sign-in. Customer access tokens are encrypted using AES-256-GCM encryption at rest.

Generative AI. The Platform uses third-party AI and large language model services, including Google Gemini, Anthropic Claude, and OpenAI GPT. These services may produce errors, omissions, or inaccurate code ("hallucinations"). It is Customer's sole responsibility to verify the accuracy, safety, and suitability of any AI-generated code before deployment.

14. Credits, subscriptions, and payments

The Platform uses a credit-based billing model. AI chat interactions consume credits from Customer's balance based on token usage. Credit rates are published on the Pricing page. Deploys, file edits, project creation, and code viewing do not consume credits.

The Company may offer optional subscription plans that provide recurring monthly credit allowances, top-up bonuses, and additional features. Subscription Fees are stated in US dollars and charged via Customer's selected payment method at the beginning of each Subscription Term.

Credits are non-refundable once purchased. Fees are exclusive of applicable taxes (including VAT, sales tax, GST, etc.). The Company will charge applicable taxes where legally required. Delinquent payments may bear interest at a rate equal to the lower of 1.5% per month or the highest rate permitted by law.

Stripe processes all payments. Your payment card details are never stored on SheetEngine's servers.

15. Subscription auto-renewal

Subscription plans automatically renew at the end of each term unless canceled at least 30 days before expiration. Renewals are charged at then-current rates, excluding any introductory discounts from prior terms. You may turn off auto-renewal or cancel at any time via Account settings or by contacting compliance@sheetengine.app.

Renewal charges are non-refundable once a renewal term begins, except as required by mandatory local law. Customer is solely responsible for verifying that Subscriptions renew successfully. The Company is not liable for interruptions resulting from payment failures or disabled auto-renewal.

16. Term and termination

The Company may terminate or suspend Customer's access to the Platform immediately, without prior notice or liability, where: (i) Company believes Customer is using the Platform in a manner that poses a security risk or may cause harm to the Company or any third party; (ii) Customer is using the Platform in breach of the "Acceptable Use" section; or (iii) Customer's credit balance is depleted or payment cannot be processed.

Customer may terminate access at any time by turning off auto-renewal in Account settings or by contacting Support. Upon termination, all licenses and rights granted hereunder shall immediately expire.

If requested in writing within 15 days of termination, the Company shall provide Customer with Customer Data then held by the Company in a standard format. Following that 15-day period, the Company may permanently delete all Customer Data. Note: code already deployed to your Google Sheet lives in your Google account and is not affected by account deletion.

17. Warranty disclaimer

The Platform is provided "as is," "as available," and "with all faults." To the fullest extent permitted by applicable law, the Company disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, availability, security, or non-infringement. The Company does not warrant that the Platform will be uninterrupted, error-free, timely, secure, or free of vulnerabilities.

The Company further disclaims all warranties in connection with third-party services and AI services, including Google Drive, Google Sheets, Google Apps Script, and all AI model providers.

Customer is solely responsible for reviewing, testing, and validating all Generated Output - including all Apps Script code deployed to Customer's Google account - before use in production. AI-generated code may contain errors, security vulnerabilities, or logic defects. Deployment of Generated Output is at Customer's sole discretion and risk.

18. Limitation of liability

To the fullest extent permitted by applicable law, and other than in cases of fraud, gross negligence, willful misconduct, or infringement of intellectual property rights, in no event shall either party be liable for: (i) special, incidental, punitive, consequential, or indirect damages; (ii) loss of data, goodwill, profits, revenue, or business; or (iii) the cost of procuring substitute goods, services, or technology; regardless of whether the party had been advised of the possibility of such damages or the theory of liability.

Either party's aggregate and cumulative liability for all direct claims is limited to the fees or credits paid by Customer to the Company in the twelve (12) months preceding the last event giving rise to the claim.

19. Indemnification

Customer agrees to defend and indemnify Company, its affiliates, and their respective employees and agents against any and all liabilities, damages, and costs (including reasonable attorneys' fees) arising out of any third-party claim: (i) alleging that Customer Data, Input Data, Generated Output, or Customer's use of the Platform infringes any third party's intellectual property rights; (ii) alleging that Customer Data or Customer's use of the Platform violates applicable law or any privacy rights; (iii) arising from misuse of the Platform or Account; or (iv) arising from a third party's use of applications or automations created via Generated Output.

20. Dispute resolution and arbitration

Please read this section carefully - it may significantly affect your legal rights, including your right to file a lawsuit in court and to participate in class actions.

Unless prohibited by applicable law, all disputes between you and the Company shall be resolved only on an individual basis. You do not have the right to bring any claim as a plaintiff or member of a class, consolidated, collective, or representative action.

Arbitration. If you reside in the United States or any jurisdiction where the following is not prohibited, any dispute, controversy, or claim relating to the Company's services, Website, or Platform will be resolved by final and binding arbitration, administered by JAMS under its Comprehensive Arbitration Rules and Procedures, using the English language. Judgment on the arbitration award may be entered in any court with jurisdiction. The following disputes will be resolved in a court of proper jurisdiction rather than arbitration: (i) disputes within small claims court jurisdiction maintained as an individual dispute; (ii) disputes where the sole relief sought is injunctive relief; and (iii) intellectual property disputes.

Mass Arbitration. If 10 or more substantially similar arbitration demands are filed, they will be treated as a Mass Arbitration and conducted pursuant to JAMS Mass Arbitration Procedures.

Opt Out. You have the right to opt out of binding arbitration by emailing compliance@sheetengine.app within 30 days of first registering for the Platform or first agreeing to these Terms. Your opt-out email must be sent from your Account email address and must include your full name, mailing address, and a clear statement that you are opting out of arbitration.

Class action waiver: To the fullest extent permitted by applicable law, you and the Company each agree that any proceeding will be brought only in your individual capacity and not as part of any class, consolidated, multiple-plaintiff, or representative action. You waive the right to participate as a plaintiff or class member in any class action. The arbitrator may not combine or aggregate claims or conduct a class action.

21. Miscellaneous

  • Amendments. The Company may change these Terms from time to time. Changes become effective upon posting to the Website or notification via the Platform. Continued use of the Platform constitutes acceptance of the revised Terms. Subscription Fee increases take effect at the end of the then-current Subscription Term.
  • Export Control. Customer agrees that it is not located in, or using the Platform in violation of, U.S. or foreign export controls, laws, and regulations. Customer is solely responsible for complying with applicable export controls.
  • Customer Reference. During any active use of the Platform, the Company may use Customer's name and logo to identify Customer as a user of the Platform on the Company's Website or marketing materials. Case studies or additional content require Customer's prior written approval.
  • Force Majeure. Neither party will be liable for failure or delay due to events beyond reasonable control, including internet failures, AI service outages, denial-of-service attacks, fires, acts of God, war, pandemic, or governmental action. This provision does not relieve Customer of payment obligations.
  • Relationship of the Parties. The parties are independent contractors. These Terms do not create a partnership, franchise, joint venture, agency, fiduciary, or employment relationship.
  • Entire Agreement. These Terms (together with all terms, agreements, and policies referenced herein) constitute the entire agreement between the parties and supersede all prior understandings.
  • Assignment. The Company may assign these Terms and any of its rights to any third party without Customer's consent. Customer may not assign any rights or delegate obligations without the Company's prior written consent. Unauthorized assignments are null and void.
  • Enforceability. If any provision of these Terms is found to be unlawful or unenforceable, it will be deemed severable and will not affect the validity of any remaining provisions.
  • No Waiver. The failure of either party to enforce any right or provision will not constitute a waiver unless acknowledged in writing.
  • Governing Law; Jurisdiction. These Terms are governed by the laws of the State of New York, without regard to conflict of laws provisions. The parties submit to the exclusive jurisdiction of the competent courts of New York County, New York. The UN Convention on Contracts for the International Sale of Goods shall not apply.
