Terms of Service
Effective date: October 29, 2026. These terms are an agreement between you (the business using zentroStack) and Zentro Technologies, a sole proprietorship owned by Subodh Banerjee (“zentroStack”, “we”). By creating an account or using the apps, you agree to them.
1. The Service
zentroStack provides software apps for small businesses, including AI call answering, AI messaging, CRM, online booking, quotes, e-signature and invoicing. Features may change as we improve the service.
2. Your Account
You must give accurate details, keep your login secure and be at least 18. You are responsible for everything done under your account, including by your team members.
3. Free Trial
New accounts get a 60-day free trial with no card needed. At the end of the trial, you choose a paid plan to keep using the apps. The trial includes up to 3 users and 1,000 contacts. WhatsApp replies need a paid plan. On request, the trial can include a US phone number with 60 AI call minutes.
4. Plans and Payment
Paid plans are billed monthly or yearly in advance at the prices shown for your plan on our website. Each plan includes the AI call minutes and AI chat conversations shown for that plan. Use above those amounts is charged at the rates shown for your plan. Prices may change with 30 days’ notice by email. Fees are non-refundable except where the law requires.
5. Your Responsibilities When Using AI
- You decide what information the AI uses and you keep it accurate.
- You must tell your customers where the law requires that they are speaking with an AI and that calls or messages may be recorded or stored.
- You must follow the laws that apply to your calls and messages, including consent and marketing rules such as the TCPA in the US, PECR and UK GDPR in the UK, GDPR in the EU and the Spam Act in Australia, and the policies of WhatsApp, Meta and your phone provider.
- You check important answers, prices and commitments. The AI takes details for you to confirm and is not a substitute for your own judgement.
6. Acceptable Use
You may not use zentroStack to send spam, harass people, break the law, impersonate others, collect data without consent or try to break or misuse the service.
7. Your Data
You own your data and your customers’ data. You give us permission to process it only to provide and improve the service, as described in our Privacy Policy. You can export your data while your account is active. We keep your data for 90 days after your account closes, then delete it.
8. Third-Party Services
zentroStack connects to services such as WhatsApp, Instagram, Messenger, Stripe and phone networks. Their own terms apply, and we are not responsible for their availability or changes.
9. Availability
We work to keep zentroStack running, but we do not promise it will be uninterrupted or error-free. Planned maintenance will be announced where possible.
10. Limitation of Liability
To the extent the law allows, zentroStack is not liable for indirect or consequential losses, including lost profits or lost business, and our total liability is limited to the fees you paid in the 12 months before the claim.
11. Cancellation
You can cancel any time from your account. Access continues until the end of the paid period. We may suspend or close accounts that break these terms.
12. Changes to These Terms
We may update these terms and will tell you about important changes by email before they take effect.
13. Governing Law
These terms are governed by the laws of the State of California, USA.
