Terms of Service
Last Updated: April 9, 2026
Welcome to Charts AI for Slack (“we,” “us,” or “our”). These Terms of Service (“Terms”) govern your access to and use of the Charts AI Slack application and related services available at chartsai.pro (collectively, the “Service”). By installing, accessing, or using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of an organization, you represent that you have the authority to bind that organization to these Terms.
1. Acceptance of Terms
By installing Charts AI in your Slack workspace, clicking “Add to Slack,” or using any feature of the Service, you acknowledge that you have read, understood, and agree to these Terms and our Privacy Policy. If you do not agree, you must uninstall the app and cease all use of the Service.
2. Description of Service
Charts AI is a Slack application that uses artificial intelligence (large language models) to generate charts and data visualizations based on text prompts, images, audio recordings, and PDF documents that you provide. The Service operates through direct messages, @mentions in channels, slash commands (/chart, /billing, /settings, /support), and message shortcuts within Slack.
3. Eligibility
You must be at least 16 years old to use the Service. By using the Service, you represent and warrant that you meet this age requirement and have the legal capacity to enter into these Terms.
4. User Accounts & Workspaces
The Service is provisioned at the Slack workspace level. One active installation covers all users within that workspace. You are responsible for maintaining the security of your Slack workspace and all activity that occurs under your installation.
5. Acceptable Use Policy
You agree not to use the Service to:
- Generate content that is illegal, harmful, threatening, abusive, harassing, defamatory, obscene, or otherwise objectionable.
- Create misleading or fraudulent data visualizations intended to deceive others.
- Upload or process files that contain malware, viruses, or any harmful code.
- Attempt to reverse-engineer, decompile, or extract source code from the Service.
- Circumvent, disable, or interfere with security features of the Service, including token limits or billing controls.
- Violate any applicable local, state, national, or international law or regulation.
- Send content that violates Slack’s Acceptable Use Policy.
We reserve the right to refuse service, throttle usage, or remove content that violates this policy without prior notice.
6. Subscriptions, Tokens & Payments
6.1 Token System
Chart generation consumes tokens. Each chart generated costs 6 tokens. If you generate multiple charts in a single request, the cost is 6 tokens per chart. Tokens are deducted from your workspace’s balance upon successful generation.
6.2 Plans
We offer two types of plans:
- Subscription Plans (Starter, Pro, Agency): Billed monthly. Subscription tokens refresh each billing cycle and expire at the end of each period. Unused subscription tokens do not roll over.
- One-Time Token Packs (Mini, Standard, Mega): Purchased once. Permanent tokens never expire and persist until used.
When tokens are consumed, subscription tokens are deducted first, followed by permanent tokens.
6.3 Payment Processing
Payments are processed by Lava.top using Unlimit as the payment backend. You agree to provide accurate billing information. We do not store or have access to your credit card or payment method details.
6.4 Cancellation & Refunds
You may cancel your subscription at any time via the /billing command in Slack. Upon cancellation, your subscription remains active until the end of the current billing period, and no further charges will occur. Subscription payments are non-refundable except where required by applicable law. One-time token purchases are non-refundable once tokens have been delivered to your workspace.
If you believe you were charged in error, please contact us at [email protected] within 14 days of the charge and we will review your case.
7. Intellectual Property
7.1 Your Content
You retain all rights to the prompts, data, files, and other content you submit to the Service (“Your Content”). By using the Service, you grant us a limited, non-exclusive license to process Your Content solely to provide the Service.
7.2 Generated Charts
Charts and visualizations produced by the Service (“Output”) are generated using AI. Subject to your compliance with these Terms, you may use Output for any lawful purpose, including commercial use. We do not claim ownership of Output. However, due to the nature of AI-generated content, we cannot guarantee that Output is unique or free from similarities to other AI-generated works, and we make no representations regarding copyright eligibility of Output.
7.3 Our Intellectual Property
The Service, including its code, design, branding, documentation, and underlying technology, is owned by us and protected by intellectual property laws. Nothing in these Terms grants you any right to use our trademarks, logos, or brand assets.
8. AI Disclaimer & Accuracy
The Service uses generative AI (large language models) to interpret your requests and produce charts. AI-generated output may contain errors, inaccuracies, or unexpected results. You are solely responsible for reviewing and verifying all charts before relying on them for business, financial, medical, legal, or any other decisions. We are not liable for any consequences arising from reliance on AI-generated output.
9. Service Availability
We strive to keep the Service available and functional, but we do not guarantee uninterrupted or error-free operation. The Service may be temporarily unavailable due to maintenance, updates, or factors beyond our control (including third-party API outages from Slack, Google, or others). We will make reasonable efforts to notify users of planned downtime when possible.
10. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE, OUR OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATED TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR USD $50, WHICHEVER IS GREATER.
11. Disclaimer of Warranties
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS, BE ACCURATE, RELIABLE, OR ERROR-FREE, OR THAT ANY DEFECTS WILL BE CORRECTED.
12. Indemnification
You agree to indemnify, defend, and hold harmless Charts AI and its operators from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or relating to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any third-party rights; or (d) Your Content submitted to the Service.
13. Termination
We reserve the right to suspend or terminate your access to the Service at any time, with or without cause, particularly in cases of:
- Violation of these Terms or the Acceptable Use Policy.
- Fraudulent, abusive, or suspicious activity.
- Non-payment of subscription fees.
- Requests by law enforcement or government agencies.
You may terminate your use at any time by uninstalling the app from your Slack workspace. Upon termination, your right to use the Service ceases immediately. See our Privacy Policy for details on data retention after termination.
14. Changes to These Terms
We may modify these Terms at any time. When we make material changes, we will update the “Last Updated” date and make reasonable efforts to notify you (e.g., via a Slack message to installed workspaces or a notice on our website). Your continued use of the Service after changes take effect constitutes your acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the Service.
15. Governing Law & Dispute Resolution
These Terms shall be governed by and construed in accordance with applicable laws, without regard to conflict-of-law principles. Any disputes arising from or relating to these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If a resolution cannot be reached within 30 days, either party may pursue binding arbitration or litigation in the courts of competent jurisdiction.
16. Severability
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
17. Entire Agreement
These Terms, together with our Privacy Policy, constitute the entire agreement between you and Charts AI regarding the Service and supersede all prior agreements and understandings.
