Terms of Service

Last updated: July 20, 2026
Service: Chamter (https://chamter.com)
Provider: Tengri Vertex (doing business as Chamter)

These Terms are written for production use (including Google OAuth app verification) and should be reviewed by counsel before you rely on them for paid enterprise deals or regulated markets. They are not legal advice.

1. Agreement to these Terms

These Terms of Service ("Terms") form a binding agreement between you and Tengri Vertex ("Tengri Vertex," "we," "us," or "our"), operating the Chamter service. By creating an account, accessing the Service, or clicking to accept, you agree to these Terms and to our Privacy Policy, which is incorporated by reference.

If you use the Service on behalf of an organization, you represent that you have authority to bind that organization, and "you" means that organization.

If you do not agree, do not use the Service.

2. The Service

Chamter provides software tools for go-to-market work, including without limitation:

  • Ingesting and analyzing owned web content
  • Helping form evidence-backed answers and buyer intents (GEO)
  • Publishing public answer pages designed to be machine-findable and citable
  • Inbound contact collection and workspace Inbox features
  • Outbound campaign research and account tooling
  • Email Sequences that send from a mailbox you connect, on your instruction

Features may change, and some capabilities may be limited by plan, geography, beta flags, or third-party platform rules (for example Google OAuth verification status).

3. Accounts and workspaces

  • You must provide accurate registration information and keep it current.
  • You are responsible for activity under your accounts and for safeguarding credentials.
  • Workspace owners are responsible for members they invite and for data those members upload.
  • We may require a work email domain and may refuse personal email domains where the product is designed for organizations.
  • You must be at least 16 years old (or the higher age of digital consent in your jurisdiction) and able to form a binding contract.

4. Your content and customer data

"Customer Content" means content and data you or your users submit to the Service, including websites you connect, lists, templates, campaign materials, and messages you choose to send.

You retain ownership of Customer Content. You grant us a worldwide, non-exclusive license to host, process, transmit, display, and create derivative works from Customer Content solely to provide, secure, maintain, and improve the Service, and as otherwise described in the Privacy Policy.

You represent and warrant that you have all rights and lawful bases needed to submit Customer Content and to process any personal data of third parties (including sequence recipients and inbound leads) through the Service. You are responsible for notices, consents, and suppression obligations under laws that apply to your campaigns (including, where applicable, U.S. CAN-SPAM, Korea's Network Act, Japan's Act on Regulation of Transmission of Specified Electronic Mail and related commercial-email rules, GDPR, and similar laws).

5. Email, Gmail connection, and Sequences

  • When you connect Gmail or another provider, you authorize us to send email as you using the scopes you grant. Default Sequences design uses send capability, not full mailbox surveillance.
  • You are the sender of commercial or outreach email initiated through Sequences. We provide software tools; we are not the originator of your marketing claims to recipients.
  • You must only enroll addresses you may lawfully contact. Cold outreach to scraped Korean lists without prior consent is prohibited. You must honor opt-outs and maintain suppression.
  • You must not use the Service to spam, phish, spoof, harvest, or send malware, or to evade provider limits and reputation systems.
  • Deliverability is not guaranteed. Provider policies (Google, Microsoft, and others) can delay, filter, or block mail. Domain reputation risk from your sending practices remains yours.
  • You can disconnect mailbox access at any time. We may suspend sending features for abuse, legal risk, or platform policy violations.

6. Public pages and GEO

If you publish public answer pages or other public content through the Service, you understand that such content is intended to be available on the open web and may be fetched, indexed, summarized, or cited by third parties, including AI systems. We do not control those third parties and do not guarantee citation, ranking, or discovery outcomes. Any estimates or measurements we show are informational and may be incomplete.

7. AI features

The Service uses artificial intelligence and automated systems. Outputs may be inaccurate, incomplete, or unsuitable. You must review outputs before publishing, sending, or relying on them for business decisions. Outputs are not legal, financial, tax, or other professional advice.

8. Acceptable use

You will not, and will not allow others to:

  • Violate law or third-party rights
  • Upload unlawful, infringing, defamatory, or deceptive content
  • Attempt unauthorized access, probe, or disrupt the Service
  • Reverse engineer the Service except where non-waivable law allows
  • Resell or provide the Service to third parties except as we expressly permit
  • Use the Service to build a competing product by systematically extracting non-public features or data
  • Misrepresent affiliation with us or with third parties
  • Bypass plan limits, rate limits, or safety controls

We may investigate violations and suspend or terminate access, remove content, or report conduct to authorities.

9. Third-party services

The Service depends on third parties (hosting, databases, AI model providers, Google, analytics, and others). Their terms and privacy policies apply to their services. We are not responsible for third-party outages, policy changes, or decisions (including OAuth verification, mailbox limits, or model provider refusals).

10. Fees, credits, and taxes

Some features may require payment or usage credits. Prices, credit consumption, and plan limits will be shown in the product or order form at the time of purchase. Unless stated otherwise, fees are non-refundable except where required by law. You are responsible for applicable taxes. We may change pricing with notice for renewal periods; continued use after a change takes effect constitutes acceptance where permitted.

11. Intellectual property

We and our licensors own the Service, including software, designs, brand, documentation, and aggregated insights that do not identify you. These Terms do not transfer our IP to you. We grant you a limited, non-exclusive, non-transferable right to use the Service during the term in accordance with these Terms.

Feedback you provide may be used by us without restriction or compensation.

12. Confidentiality

Each party may receive non-public information from the other that is marked confidential or should reasonably be understood as confidential. The receiving party will use that information only to perform under these Terms and will protect it with reasonable care. Exceptions include information that is public, independently developed, or rightfully received from a third party without duty of confidentiality, and disclosures required by law (with notice where legally allowed).

13. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT RESULTS (INCLUDING CITATIONS, RANKINGS, DELIVERABILITY, LEAD QUALITY, OR BUSINESS OUTCOMES) WILL MEET YOUR EXPECTATIONS.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TENGRI VERTEX AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, COVER, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY.

OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY, OR (B) ONE HUNDRED U.S. DOLLARS (US $100).

Some jurisdictions do not allow certain limitations; in those cases our liability is limited to the maximum extent permitted.

15. Indemnification

You will defend, indemnify, and hold harmless Tengri Vertexand its affiliates, officers, and employees from and against claims, damages, losses, and expenses (including reasonable attorneys' fees) arising from: (a) Customer Content; (b) your emails, lists, and outreach; (c) your violation of these Terms or law; or (d) your use of the Service in a manner that infringes third-party rights.

16. Term and termination

These Terms start when you first accept them or use the Service and continue until terminated. You may stop using the Service at any time. We may suspend or terminate access immediately if you breach these Terms, create risk, or if required by law or a platform partner. Upon termination, your license ends. Sections that by nature should survive (including IP, disclaimers, liability limits, indemnity, and governing law) will survive.

17. Governing law and disputes

These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-law rules. Except where prohibited, exclusive venue for disputes lies in the state or federal courts located in San Francisco County, California, and you consent to personal jurisdiction there.

Before filing a claim, you agree to try to resolve the dispute informally by contacting legal@chamter.com. Nothing in these Terms limits either party's right to seek injunctive relief for IP or unauthorized access.

18. General

  • Changes: We may update these Terms by posting a revised version. Material changes will be indicated by updating the date and, where required, additional notice. Continued use after the effective date constitutes acceptance where permitted.
  • Export and sanctions: You must comply with applicable export and sanctions laws and may not use the Service if you are prohibited from receiving U.S. services.
  • Force majeure: We are not liable for delays or failures caused by events beyond our reasonable control.
  • Assignment: You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets.
  • Severability: If a provision is unenforceable, the remainder stays in effect.
  • Entire agreement: These Terms and the Privacy Policy are the entire agreement regarding the Service and supersede prior proposals on the same subject. Enterprise order forms, if any, control over these Terms for conflicting commercial terms only.
  • No waiver: Failure to enforce a provision is not a waiver.
  • Notices: We may notify you via the Service, account email, or the addresses below. Legal notices to us must go to legal@chamter.com and the postal address below.
