Terms of Service

These Terms govern the use of volai - a platform for phone numbers, calls, SMS and an AI voice agent, available through the web interface, REST API and MCP server at volai.cz (the "Service"). By registering an account or using an API key, you agree to these Terms.

1. Who operates the Service

volai is operated by ANOVIA Finance s.r.o. (Company ID 01757237, VAT ID CZ01757237), with its registered office at Na Zámku 636, 250 81 Nehvizdy, Czech Republic, entered in the Commercial Register maintained by the Municipal Court in Prague (Městský soud v Praze), Section C, Insert 266323 (the "Operator"). Contact: podpora@volai.cz. The Operator complies with the obligations under Act No. 127/2005 Coll., on Electronic Communications.

The volai connector for OpenAI is published by Fabikonam, s.r.o. (Company ID 23918560), with its registered office at Dominikánské náměstí 656/2, Brno-město, 602 00 Brno, Czech Republic, with authorization from ANOVIA Finance s.r.o. Fabikonam acts solely as the connector publisher. ANOVIA Finance s.r.o. remains the operator of the volai account, telephony and related AI services, and the customer's contracting party. Connecting the connector does not transfer the customer's account, credit or contract to Fabikonam.

2. Registration and account

Creating an account requires only a valid email address and a password. You agree to provide accurate information and to keep your login credentials and API keys safe from misuse - you are responsible for all activity under your account until you notify us that a key has been lost or compromised. When you purchase a geographic phone number, we store your address, since it is tied to emergency-calling requirements.

3. How the Service works

volai provides phone numbers and carries calls and SMS through a contracted partner - a Czech telecommunications operator - and runs the voice AI agent through a voice technology provider. For the SMS number add-on, the number and SMS transport are provided by Twilio (USA), not by a Czech operator. The SMS number is meant for texting with people: we do not guarantee verification codes from services, or the delivery of SMS from every sender. For the calls and SMS number, the number, calls and SMS are provided by DIDWW Ireland Limited (Ireland), not by a Czech operator. The number is registered with the number supplier in the name and at the address of the Operator, and the customer only uses it for as long as the add-on lasts. The same applies to this number: we do not guarantee verification codes from services, or the delivery of SMS from every sender. For a number in another country the supplier of the number and calls is likewise DIDWW Ireland Limited (Ireland). The number is registered with the supplier in the name of the provider with its address in that country, and the customer only uses it for as long as it lasts. The number is for calls only, with no SMS: it neither receives nor sends them, and it calls out only to the country of the number and to Czechia. Registration usually takes up to 1 business day and no longer than 3 business days (within the hour for countries without registration). The Service is currently in beta, without a guaranteed SLA. We aim for continuous, reliable operation, but we cannot guarantee full uptime or error-free operation. For emergency calls (112, 150, 155, 158), always use your mobile operator as the primary line - volai is not intended as your sole line for emergency calls.

4. Call recording

Calls handled by the voice agent are recorded by default. You can play a recording from the call's detail view in the portal; we keep it for 90 days after the call and then delete it - the call transcript stays in your account. Access to a recording is limited to you and our support team, when helping you with a specific call. You can turn recording off with a toggle on the agent - calls made by that agent stop being recorded from that point on. By default, the agent does not tell the caller that the call is recorded. If you turn on the recording notice for the agent, it says so at the end of its first line. Informing the caller as required by law remains your responsibility as the data controller. In addition, once a week we use calls handled by the own voice engine, in pseudonymized form (names, companies, places, contact details and sensitive numbers replaced with placeholders or random digits), for internal quality control of the voice agent. You will find the details, including how to opt out of the evaluation, in the privacy policy.

5. Voice agent tools

You can configure a tool for your agent - the address of your own endpoint, which it calls during the call and uses the response in speech. You determine the address, request headers, and the list of parameters sent, and you are therefore responsible for what your endpoint does and what data we send it - which may include the caller's number and information the agent gathers during the call. We only relay the call: we send the request and pass the response to the agent. We are not responsible for the availability, content, or security of your endpoint.

6. Credit and payments

The Service runs on prepaid credit. Prices for individual actions (calls, SMS, phone numbers, the voice agent) follow the current pricing page, always available on the website. You top up credit by card, and it is drawn down as you actually use the Service; topped-up credit never expires and does not lapse. You can also choose the optional monthly plan under Section 11, whose monthly credit follows its own rules and expires at the end of its period. Once your email is verified, a new account receives a one-time free welcome credit. A phone number obtained only with the welcome credit stays yours while you use the account. If you have not topped up and do not use the account for an extended period (no sign-in, no outgoing calls, no API use), we release the number back to the offer after an e-mail notice; your account, agent and remaining credit stay, and you can get a new number again. The SMS number add-on costs 390 CZK per 30 days excluding VAT; the fee is charged from your credit when you buy the number and then every 30 days. Received SMS are included in that price within normal use (fair use), and an SMS sent from the number costs 1.90 CZK per segment excluding VAT. We may release the SMS number in case of obvious abuse, or when your credit does not cover the fee and you do not top it up even after an e-mail notice. The period already paid for is not refunded when a number is released. The calls and SMS number costs 49 CZK per 30 days excluding VAT. After you order it, the number is registered with the number supplier, usually within 1 business day, and the fee is charged from your credit only after the number is activated and then every 30 days. You can cancel an order free of charge until the registration is approved, and if the number supplier rejects the registration, nothing is charged. Received SMS are included in that price within normal use (fair use), and an SMS sent from the number costs 2.50 CZK per segment excluding VAT, goes only to Czech numbers and has no delivery reports; calls are billed at the prices on the pricing page. We may also release this number in case of obvious abuse, or when your credit does not cover the fee and you do not top it up even after an e-mail notice. The period already paid for is not refunded when a number is released. A number in another country costs the same as the calls and SMS number and the same rules apply: the fee is charged from the credit only once the number is active and every 30 days after that, the order can be cancelled free of charge until the registration is approved, calls are billed at the price list, and the paid period is not refunded when the number is released. The number has no SMS. An account can hold at most 2 such numbers in one country and at most 4 numbers from the supplier of the number in total. Any remaining topped-up credit is refunded on request through support.

7. Prices, VAT, and invoices

The Operator is registered for VAT. Prices listed on the pricing page are exclusive of VAT. Topping up credit and the price of the monthly plan add VAT at the statutory rate (21%) - so you pay more than the price listed or the amount credited to your balance.

If you are registered for tax in another EU member state and provide your VAT number, the place of supply is your own country (§ 9(1) of the Czech VAT Act). In that case we invoice without Czech VAT and you self-assess and pay the tax in your own country; the invoice states "Tax to be paid by the customer" (reverse charge). This only applies once your VAT number is confirmed by the EU's VIES register - we verify it the moment you save it, and until confirmed we charge Czech VAT.

We issue a tax invoice automatically for every credit top-up made by card and for every paid period of the monthly plan, and you'll find it in the portal under Credit, where you can download it as a PDF. It is issued using the billing details you have set in your account settings at the moment of payment - an invoice already issued is not amended retroactively, so add your details before you top up. For payers outside the EU we issue the invoice manually - email us at podpora@volai.cz.

8. Liability and limitations

The Service is provided "as is", in beta, and without an SLA. We are not liable for damage caused by third-party outages (telecommunications network, voice technology, payment gateway), for the content of calls and SMS sent from your account, or for indirect or consequential damages. In any event, our liability is limited to the amounts you paid us for topped-up credit and for the monthly plan over the preceding 12 months.

9. Termination and account cancellation

You may cancel your account at any time, with no notice period and no reason required - any remaining topped-up credit is refunded on request. The monthly plan credit is non-refundable (Section 11). The Operator may suspend or terminate an account for breach of these Terms, misuse of the Service (spam, fraudulent calls, harassment), or a persistently negative credit balance following prior notice.

10. Prohibited use

• Mass unsolicited calling or SMS (spam, telemarketing without consent).
• Fraudulent, threatening or harassing calls and messages.
• Spoofing caller identification or impersonating another person or company.
• Mass creation or verification of accounts with third parties and circumventing their protections against abuse.
• Any conduct contrary to the applicable law of the Czech Republic.

11. Monthly plan

What you get. The monthly plan is an optional subscription. For the monthly price of the tier you choose, shown on the pricing page, we add a monthly credit in CZK to your account for each period. The monthly credit is spent at the standard price list and is used first for every charge; only once it is used up is topped-up credit drawn down under Section 6. The balance you see on the account is the sum of both kinds of credit.

Expiry and non-refundable credit. The unused rest of the monthly credit expires at the end of the period and is not carried over to the next one. The monthly credit is non-refundable and cannot be paid out; for a consumer who withdraws from the contract before the service has been fully provided, the proportional payment under the Consumers paragraph below applies. Topped-up credit stays separate: it does not expire and is refundable under Sections 6 and 9.

Cancellation. You can cancel the plan at any time in the portal, through the API or over MCP. Canceling ends the plan at the end of the period already paid, and until then you keep spending the monthly credit. No prorated part of the paid period is refunded on cancellation; a consumer's right to withdraw under the Consumers paragraph below is not affected. You can undo a cancellation until the end of the period.

Changing tier. You can change tier at any time. The change takes effect from the next period: the next charge is already at the new price and adds the new tier's credit, and nothing is adjusted within the current period.

Renewal and payment. The plan renews every month. On the renewal day we charge the price of your tier to the saved payment card you entered when you turned on the plan, and after a successful charge we add the new monthly credit; the unused rest of the previous one is cancelled at that moment. The price of the tier is the price in the price list valid on the day of the charge. We notify you of a price change by email at least 30 days before the first charge at the new price; until then you can cancel the plan and the new price does not affect you. VAT is added under the regime that applies on the day of the charge: Czech VAT, or none for a business registered in another EU member state with a verified VAT number (Section 7). We issue a tax invoice for every paid period automatically and you will find it in the portal.

Unpaid renewal. If a charge fails we try again, three times in total: on the renewal day, after 2 days and after 4 days. After the first failed attempt we email you a link to pay manually and to change the card. Until it is paid no monthly credit is added and the account keeps running on topped-up credit. If the third attempt fails as well, the plan ends.

Consent to recurring charges. By turning on the plan and ticking the consent, you agree to recurring monthly charges of the price of your tier to the saved card. You can withdraw it by canceling the plan; no further charge for the plan is made afterwards. Auto top-up, if you chose it, does not end with the plan and is turned off separately in the portal.

After the monthly credit runs out. When you turn on the plan you choose what happens once the monthly credit is used up: either topped-up credit is bought from the saved card in steps of 200 CZK (auto top-up, which requires your separate consent and has its own limits), or a cap applies, where nothing is bought: once both the monthly and the topped-up credit are used up, outbound calls, SMS and purchases are refused until the next renewal or until you top up by hand, inbound calls are still answered up to a debt of 50 CZK, and that debt is settled from the next monthly credit. You can change the choice at any time.

Consumers. If you are a consumer (an account without a company ID, VAT ID or company name), turning on the plan requires your express request that we start providing the service (adding the monthly credit to your account) before the 14-day withdrawal period for a contract concluded at a distance has expired; only you make that request yourself, in the form in the portal. By ticking the request you also acknowledge that once the service has been fully provided (the monthly credit is used up or the paid period has passed) the right to withdraw lapses (Section 1837(a) of the Czech Civil Code), and that if you withdraw earlier you pay a proportional part of the price for the service provided until then (Section 1834) and we refund the rest. The plan cannot be turned on without it.

Consumer withdrawal. As a consumer you may withdraw from the plan contract within 14 days of paying the first period without giving a reason, preferably by email to podpora@volai.cz from the email address of your account; you may use the model form below, but you do not have to. The proportional part of the price for the service provided until withdrawal is calculated from the monthly credit used up: the tier price excluding VAT multiplied by the monthly credit used up and divided by the tier's monthly credit, plus VAT under the same regime you paid in. We refund the rest of the amount paid within 14 days of the withdrawal by the same means you used to pay, that is to your payment card. Withdrawal ends the plan and cancels the remaining monthly credit; topped-up credit and the account stay.

Model withdrawal form. Complete and return this form only if you wish to withdraw from the contract. To: ANOVIA Finance s.r.o., Na Zámku 636, 250 81 Nehvizdy, Czech Republic, podpora@volai.cz. I hereby give notice that I withdraw from my contract for the provision of the volai monthly plan service. Date of payment of the first period: … Email address of the volai account: … Name of consumer: … Address of consumer: … Date: … Signature of consumer (only if this form is notified on paper): …

12. Changes to these Terms

We may amend these Terms from time to time, in particular as the Service evolves. We will notify you of material changes by email or an in-app notice at least 30 days before they take effect. You do not have to accept a change: until the day it takes effect you may cancel your account and the monthly plan without notice, we refund the remaining topped-up credit under Section 9, and the change does not affect you. Continuing to use the Service after such changes take effect constitutes your agreement to them.

13. Final provisions

These Terms are governed by the laws of the Czech Republic. We aim to resolve any disputes amicably wherever possible. Questions about these Terms or about the processing of personal data (see the Privacy Policy) should be addressed to podpora@volai.cz.
