Effective date: August 25, 2026
Zvonko is a software service operated by Filip Stanojević, a sole proprietor registered in Austria ("Zvonko", "we", "us"). Contact: filip@filipgrowthlab.com.
These terms form the agreement between us and the business that uses the service ("Client", "you"). By connecting a messaging account to Zvonko or by using the service in any way, you accept these terms.
People who message a Client's business are not parties to this agreement. Their conversations are handled by the Client, who remains the business they are talking to. How we process their data is described in our Privacy Policy.
Zvonko receives new customer inquiries arriving on a Client's connected messaging channels, such as WhatsApp, Facebook Messenger, Instagram and email. It answers first questions, gives rough price estimates based on information the Client supplies, and hands the conversation to the Client.
Depending on the Client's settings, Zvonko either drafts replies for the Client to review and send, or sends them automatically. Every conversation remains visible to the Client, who can take over at any time.
The service is for business use only. You must be at least 18 years old and authorised to act for the business you register. You are responsible for the accuracy of the information you give us, for keeping your login credentials secure, and for everything done through your account.
To use the service you authorise us to access and act on your business messaging accounts on your behalf. For WhatsApp this happens through Meta's official onboarding flow, in which we act as a Tech Provider and you remain the owner of your WhatsApp Business Account and phone number.
Your use of those channels is also governed by the platform's own rules, including Meta's terms, the WhatsApp Business Messaging Policy and the WhatsApp Commerce Policy. You are responsible for complying with them, including obtaining valid opt-in from the people you message. You can disconnect a channel at any time.
You may not use Zvonko to:
We may suspend the service immediately if we believe it is being used in breach of this section, or if a messaging platform requires us to.
Zvonko generates replies automatically using AI language models. Automated output can contain errors, and prices produced by the service are indicative estimates based on the catalogue and rules the Client provides. They are not binding offers, quotes, or contracts.
You are responsible for the content sent from your business accounts, including automated content, for keeping the pricing and product information you give us accurate and current, and for confirming final prices with your customers yourself.
Fees, the billing period and the payment method are agreed in writing with each Client before the service starts. Unless agreed otherwise, subscription fees are payable monthly in advance and are exclusive of any applicable taxes.
Charges billed by third parties for your own messaging usage, such as Meta's per-conversation fees, are separate from our fees and are set by those providers. If an invoice remains unpaid after a reminder, we may suspend the service until it is settled.
The agreement runs until either side ends it. You may end it at any time with 30 days' notice; so may we. We may terminate immediately for a material breach of these terms.
On termination we disconnect your messaging accounts from the service. Your data is deleted in line with our Privacy Policy, and you can request deletion earlier or ask for an export before you leave. See also our data deletion instructions.
We work to keep the service running reliably, but we do not guarantee uninterrupted availability. The service depends on third parties, including messaging platforms, hosting providers and AI model providers, and it can be interrupted by their outages, by maintenance, or by changes they make to their own products.
We own the software, its configuration and any improvements to it. You own your business content, your customer conversations and the product and pricing information you supply. You grant us the limited right to process that material only as needed to run the service for you.
Neither side will disclose the other's non-public business information to third parties, except to providers required to run the service or where disclosure is required by law.
The service is provided "as is". To the extent permitted by law, we make no warranty that it will be error-free, that automated replies will be accurate, or that it will produce any particular commercial result.
To the extent permitted by law, we are not liable for indirect or consequential loss, including lost profits, lost business or lost data. Our total liability arising out of the service is limited to the fees you paid us in the twelve months before the event giving rise to the claim.
Nothing in these terms excludes liability that cannot be excluded under Austrian law, including liability for intent, gross negligence, or personal injury.
You will hold us harmless against claims brought by third parties, including messaging platforms and regulators, that arise from your content, from the messages sent from your business accounts, or from your breach of these terms or of a platform's policies.
When we process personal data contained in your customers' conversations, we act as a processor on your behalf and you act as the controller. We process that data only to provide the service. A data processing agreement is available on request. Details are in our Privacy Policy.
We may update these terms as the service develops. We will give notice of material changes at least 30 days in advance by email or in the product. If you do not accept a change, you may end the agreement before it takes effect. The current version is always available at this address, with the effective date shown above.
These terms are governed by Austrian law, excluding its conflict of law rules and the UN Convention on Contracts for the International Sale of Goods. The courts competent for Vienna, Austria have exclusive jurisdiction, to the extent permitted by law.
