Terms of Service
Who you are contracting with: ZANTEMARK LIMITED, Arch. Makariou III, 195, NEOCLEOUS HOUSE 3030, Limassol, Cyprus, registration number HE 426044 (“vbtnl”, “we”, “us”). Contact: [email protected]
These Terms have four parts. Part A applies to everyone. Part B applies only if you are a consumer (a private person using vbtnl for purposes outside your trade, business or profession). Part C applies only if you use vbtnl for a business, including as a freelancer. Part D adds country-specific provisions that apply if you live or are established in the country named. Where Part B, C or D conflicts with Part A, Part B, C or D prevails for the people it applies to.
The Acceptable Use Policy and, where you process other people’s personal data with vbtnl, the Data Processing Agreement are part of these Terms. You accept all of them together.
Part A: Terms for everyone
1. Scope, language and your account type
1.1 These Terms govern your use of vbtnl: the website, the dashboard, the API, the MCP server and the hosting platform (together, the “Service”).
1.2 The contract language is English. We may provide summaries or translations for convenience; the English text prevails.
1.3 When you create an account you tell us whether you use vbtnl as a consumer or for a business. That choice decides whether Part B or Part C applies to you. You can ask us to change it if your use changes. If you tell us you are a business, we rely on that.
1.4 You must be at least 18 years old. By creating an account you confirm this. Businesses confirm that the person accepting these Terms is authorised to bind them.
1.5 Where we offer the Service. We do not offer the Service to people or companies in the United Kingdom, France, Russia or Belarus, or in a country under comprehensive EU or US sanctions (currently Cuba, Iran, North Korea and Syria). You confirm that the country you give when you sign up is where you live or, for a business, where it is established. If we learn that it is not, or that you are in one of these countries, we may end the contract under Section 13.3.
2. Definitions
“Account” is your registration with vbtnl. “Project” is an application you build and host with the Service, including its code, configuration, databases and domains. “Your Content” is everything you upload to or create in a Project, including code, data, and the personal data of the people who use your applications (“End Users”). “Plan” is the set of limits and prices you have chosen, including the free plan. “AI Assistant” is any AI coding agent you connect to the Service, such as Claude, through the MCP server or an access token.
3. The Service
3.1 vbtnl lets you write, run and publish web applications on our infrastructure through an AI Assistant or the dashboard: a sandbox for development, a production deployment, managed databases, secrets, logs, subdomains and your own domains. The features and limits of each Plan are described on the pricing page at the time you choose it.
3.2 Your AI Assistant is yours. You connect it with your own account at its provider (for example Anthropic for Claude). We are not a party to that relationship. What your AI Assistant sends to its provider is governed by that provider’s terms and privacy policy, not ours. We receive the instructions your AI Assistant gives to the Service and act on them as if they came from you.
3.2a Production data and your AI Assistant. Everything the Service returns to your AI Assistant, it sends to its provider. Your production databases and logs usually hold your End Users’ personal data, so by default your AI Assistant cannot read them: it can read the structure of a production database (tables, columns, row counts) but not its contents, and it gets production logs with email addresses, IP addresses, phone numbers, card-like numbers and secrets masked. The masking is best effort and does not catch every kind of personal data your application may write to its logs. You can allow your AI Assistant to read production data for a Project in the dashboard and switch it off again at any time; we record who changed it and when. If you allow it, you are responsible for having a lawful basis to disclose that data to your AI Assistant’s provider, including for any transfer outside the EEA, and for telling your End Users about it where the law requires. The sandbox and its development database are always available to your AI Assistant; do not copy production personal data into them.
3.3 You review what gets deployed. Code written by an AI Assistant is published under your account and is your responsibility, including its security, its legality and the data it processes.
3.4 The Service changes. We may add, change or remove features. If a change removes or materially reduces something you pay for, we will tell you at least 30 days in advance by email and in the dashboard, and you may terminate before the change takes effect; if you have prepaid, we refund the unused part. Changes needed for security, legal compliance or to keep the Service in conformity may be made without notice.
3.5 Early-stage service. vbtnl is a young product. We do not promise uninterrupted availability or that every feature works perfectly. Part B describes the rights consumers have in any case; Part C describes what businesses can expect.
4. Plans, fees and payment
4.1 The free plan costs nothing and may be limited or changed; Section 3.4 applies. Paid Plans are billed in advance, monthly or yearly, through our payment provider Stripe. We do not see or store your card details.
4.2 Prices and taxes. Prices are shown before you order. For consumers in the EU, the price shown includes VAT at the rate of your country. For businesses, prices exclude VAT; VAT is added, or reverse-charged if you give us a valid VAT number. Sales tax may be added for US customers where applicable.
4.3 Renewal. Paid Plans renew automatically for the same period until cancelled. You can cancel at any time in the dashboard (Billing → Manage subscription) or through the cancellation button; cancellation takes effect at the end of the current period and you keep access until then. We send a reminder email before a yearly Plan renews.
4.4 Price changes. We may change prices for future periods with at least 30 days’ notice by email. If you do not agree, cancel before the new price applies; the current period is unaffected.
4.5 Failed payments. If a payment fails we retry and notify you. If it keeps failing we may downgrade your Account to the free plan or suspend paid features after notice. Your Projects stay available for export (Section 8) for at least 30 days after suspension.
4.6 Refunds. Except as stated in Part B (consumers), in Section 3.4 and 4.4, or where the law requires, fees are not refundable.
4.7 Promotional codes are subject to the conditions stated when they are issued and may be withdrawn for misuse.
5. Your Content and End Users
5.1 You own Your Content. You give us only the rights we need to run the Service: to store, copy, transmit, build, execute and display Your Content for the purpose of providing, securing and supporting the Service and complying with law. We claim no other rights in your code or data.
5.2 You are responsible for Your Content, for having the rights to use it, and for the applications you publish, including what they do to End Users and what they collect from them.
5.3 End User personal data. If your applications process personal data of End Users, you are the controller of that data and we are your processor. The Data Processing Agreement governs that processing. You are responsible for the legal basis, the privacy notices your application shows and for answering End Users’ requests; the Service gives you the tools to export and delete their data.
5.4 Backups. We back up managed databases daily and keep the backups for 14 days. Backups protect the platform; they are not a substitute for your own exports. Backups cannot be restored selectively on request except where the dashboard offers it.
6. Acceptable use and enforcement
6.1 You must follow the Acceptable Use Policy. In short: nothing illegal, nothing that harms others or the platform, no abuse of the AI tooling or of the free plan.
6.2 Hosting provider. We host content for you and do not review it before it goes live. We act when we become aware of illegal content or a breach of these Terms, including through reports sent to [email protected] or the abuse form. We may use automated tools to detect malware, phishing and resource abuse.
6.3 What we may do. Depending on the severity, we may ask you to fix a problem, restrict visibility of content, suspend a Project or the Account, or terminate the contract. Where we restrict or remove content we tell you what we did and why, the facts and the rule or law relied on, whether automated tools were involved, and how to complain; urgent action to protect people or the platform may come first and be explained right after. You can object within 6 months by email; a person, not a tool, reviews objections.
6.4 Reports from others. Anyone can report content they consider illegal by email to [email protected] or through the abuse form, giving the location of the content, the reason, their name and email, and a statement that the report is made in good faith. We confirm receipt, decide without undue delay and tell the reporter the outcome.
6.5 We may suspend immediately, without notice, where there is a risk to people, to other customers or to the platform, or where the law requires.
7. Security and incidents
7.1 We protect the platform with measures described in the Data Processing Agreement, Annex II. You protect your Account: keep your credentials and access tokens secret, enable the security options we offer, and tell us at [email protected] if you suspect unauthorised access.
7.2 If a security incident affects Your Content or your Account we tell you without undue delay, with what we know and what you may need to do.
7.3 Security research. You may test the security of your own Projects. You may not test the platform or other customers’ Projects without our written agreement. Report platform vulnerabilities to [email protected]; we do not pursue good-faith reporters.
8. Switching, export and leaving
8.1 Export at any time. You can export your Project’s source code, configuration and database contents at any time in commonly used, machine-readable formats (source tree, SQL dump), free of charge, through the dashboard, the API or your AI Assistant.
8.2 Switching to another provider. You may terminate at any time with effect at the end of the paid period; no notice period longer than two months applies. After termination we keep your Projects available for export for a transition period of 30 days, running if you ask us to. If exporting within 30 days is technically not feasible for a specific Project we tell you why within 14 days of your request and extend the period once, by what is needed and at most 7 months. We charge no switching or data-egress fees.
8.3 Domains. Your own domains are yours. On termination we release them from our platform; your DNS stays under your control at your registrar.
8.4 After the transition period we delete Your Content from live systems and, within the backup cycle, from backups. Section 15 describes what we must keep.
9. Intellectual property and feedback
9.1 The Service, its software and documentation belong to us or our licensors. These Terms give you a non-exclusive, non-transferable right to use the Service according to your Plan while the contract lasts.
9.2 Open-source components are licensed under their own terms, which prevail for those components.
9.3 If you give us feedback or suggestions we may use them without obligation to you.
10. Third-party services
The Service relies on third parties: our infrastructure provider, Cloudflare (network, DNS and protection), Stripe (payments), Resend (email), Google (optional sign-in) and others listed in our Subprocessor list. Where you use their services directly (for example when you pay through Stripe’s checkout or sign in with Google), their terms also apply to that interaction.
11. Warranties and disclaimers
11.1 We provide the Service with reasonable care and skill and as described. We do not promise that it will be uninterrupted, error-free or suitable for every purpose, or that content produced by an AI Assistant is correct or secure.
11.2 Nothing in these Terms limits rights that the law gives you and that cannot be excluded. For consumers, Part B sets out the conformity remedies that apply.
12. Liability
12.1 For everyone. We are liable without limit for death or personal injury caused by our negligence, for fraud, for intent and gross negligence, and where the law does not allow limitation.
12.2 Consumers. Our liability to consumers follows the law of your country of residence to the extent it is mandatory; Part B applies. We are liable for foreseeable damage caused by our breach of these Terms.
12.3 Businesses. Part C, Section C.4 limits our liability to businesses.
12.4 We are not liable for damage caused by Your Content, your applications, your End Users, your AI Assistant or its provider, or by your failure to keep your credentials secure or to export your data when we asked you to.
13. Term, termination and account deletion
13.1 The contract starts when you create your Account and lasts until either of us ends it.
13.2 You may end it at any time by deleting your Account in the dashboard (Account → Delete account) or by emailing [email protected]. Deletion is scheduled 7 days ahead so you can change your mind; then we delete your Projects, databases, domains, tokens and personal data, except what Section 15 says we keep. A paid period already started is not refunded unless Part B or the law says otherwise.
13.3 We may end it with 30 days’ notice by email for any reason, and immediately for a serious breach of these Terms or the Acceptable Use Policy, for non-payment after notice, where we must by law, or if we stop offering the Service (then we refund prepaid fees for the unused period).
13.4 On termination Section 8 (export and transition) applies.
14. Changes to these Terms
14.1 We may change these Terms for legal, regulatory, security, technical or business reasons, including a change of the contracting entity.
14.2 Material changes take effect no earlier than 30 days after we notify you by email and in the dashboard, with a summary of what changed. You will be asked to accept the new version. If you do not agree, you may terminate free of charge before the change takes effect and export your data; if you keep using the Service after that date without accepting, we may suspend your Account until you decide. Prepaid fees for a period you cannot use because you terminated over a material change are refunded.
14.3 Editorial changes (corrections, clarifications that do not change rights or obligations) take effect on publication; we tell you about them but do not ask you to accept again.
14.4 Every version is kept, dated and identified by a hash. You can see and download every version you accepted in the dashboard under Legal.
15. What we keep after you leave
To meet legal duties and to be able to prove what was agreed, we keep after Account deletion: invoices and payment records for the period required by tax law (7 years); the record of the documents you accepted, with the request details, for the limitation period for contract claims (6 years); and a minimal record that an account existed and was deleted, so that we do not restore it from backups. The Privacy Policy explains this in detail.
16. Governing law, disputes
16.1 These Terms are governed by the law of the Republic of Cyprus. If you are a consumer, this choice does not deprive you of the protection of the mandatory consumer law of the country where you live, and you may bring proceedings in the courts of that country as well as in Cyprus.
16.2 Businesses agree that the courts of Limassol, Cyprus have exclusive jurisdiction.
16.3 Before going to court, write to [email protected]; we try to resolve complaints within 30 days.
16.4 Alternative dispute resolution. We are not obliged to, and do not, participate in dispute resolution before a consumer arbitration body.
17. General
17.1 Assignment. You may not transfer the contract without our consent. We may transfer it to a successor of our business or an affiliate: for consumers only with your agreement, which we request through a new version of these Terms under Section 14 (a change of the contracting entity is always a material change); for businesses with 30 days’ notice, after which you may terminate.
17.2 Notices to you go to the email address of your Account and the dashboard; notices to us go to [email protected] or the postal address above.
17.3 Severability. If a provision is invalid, the rest stays in force; the invalid provision is replaced by what the law provides.
17.4 Entire agreement. These Terms, the Acceptable Use Policy, the Data Processing Agreement, the Plan you chose and the documents referred to here are the whole agreement between us about the Service.
17.5 Export controls and sanctions. You may not use the Service if you are a person or entity listed under sanctions of the European Union, the United Nations, the United Kingdom or the United States, if you are owned or controlled by one, or if providing the Service to you would be prohibited by those sanctions, including because of where you are located or established. You may not use the Service for the benefit of anyone in that position. We may refuse, suspend or end the Service where we must comply with sanctions law; a refund is then given where the law allows it.
Part B: Additional terms for consumers
B.1 Who this applies to. You are a consumer if you use vbtnl for purposes outside your trade, business, craft or profession. If you use it for your own small business or freelance work, Part C applies instead.
B.2 Pre-contract information. Before you pay we show you: the main features of the Plan, the total price including taxes, the billing period and the automatic renewal, how to cancel, and your right of withdrawal. After you order we send you a confirmation email with these Terms, the version you accepted and the withdrawal information, as a copy on a durable medium.
B.3 Right of withdrawal. You may withdraw from a paid Plan within 14 days of ordering it without giving a reason, by using the “Withdraw from contract” button in the dashboard, the model form in the Withdrawal Information, or an email to [email protected]. The details, including the model form, are in the Withdrawal Information, which is part of these Terms.
B.4 Starting immediately. When you order, we ask you to expressly request that the Service starts right away, during the withdrawal period, and to acknowledge that if you then withdraw you pay a proportionate amount for the time used.
B.5 Free plan. The free plan is also a contract, for which you pay with your attention and data rather than money. You can end it at any time by deleting your Account; there is nothing to refund.
B.6 Yearly Plans. After the initial year a yearly Plan continues until you cancel. If you cancel after a renewal, we refund the unused full months of that year.
B.7 Cancellation button. You can cancel a paid Plan with the “Cancel subscription” button in the dashboard, which asks you to confirm and then sends you a confirmation by email with the date and time.
B.8 Conformity. The Service must match its description and work as a service of this kind reasonably can be expected to. If it does not, you may ask us to fix it; if we cannot within a reasonable time, you may ask for a proportionate price reduction or terminate. If we change the Service in a way that negatively affects you more than minimally, you may terminate free of charge within 30 days of our notice or of the change.
B.9 Liability. We are liable to you under the mandatory law of your country of residence. We are not liable for damage you could have avoided by following our reasonable instructions, such as exporting your data when asked.
B.10 Complaints. Write to [email protected]. If you are in Cyprus you may also contact the Consumer Protection Service of the Ministry of Energy, Commerce and Industry. Consumers elsewhere in the EU can get free help with a cross-border complaint from the European Consumer Centres Network (ECC-Net).
Part C: Additional terms for businesses
C.1 Authority. You confirm that you are entering into these Terms on behalf of a business (company, organisation, sole trader or freelancer) and that you are authorised to bind it. “You” means that business.
C.2 Data Processing Agreement. The Data Processing Agreement is incorporated and applies whenever your applications process personal data. It is accepted with these Terms; no separate signature is needed, though we will countersign a copy on request.
C.3 Taxes. Prices exclude VAT and similar taxes. EU businesses outside Cyprus with a valid VAT number are reverse-charged; you account for VAT yourself. You will give us accurate billing details and tell us when they change.
C.4 Limitation of liability. Except for the cases in Section 12.1, our total liability for all claims in any 12-month period is limited to the fees you paid us in that period (for breaches of the Data Processing Agreement: three times those fees), and we are not liable for loss of profit, revenue, business, goodwill or data, or for indirect or consequential loss. The Service is provided “as is” beyond the express commitments in these Terms.
C.5 Indemnity. You indemnify us against claims by third parties, including your End Users and authorities, arising from Your Content, your applications or your breach of these Terms, including reasonable legal costs.
C.6 No consumer rights. Part B and the consumer protections it refers to do not apply to you.
C.7 Service levels. We do not offer a service level agreement on the standard Plans. We publish availability information and incident reports in the dashboard.
C.8 Switching (Data Act). Section 8 implements our obligations as a provider of a data processing service under Regulation (EU) 2023/2854. In addition: we will provide reasonable assistance with migration, at no charge for the standard export tools and at our standard rates for bespoke work; we maintain documentation of the export formats; and we do not stand in the way of your contracting with another provider.
Part D: Country-specific terms
D.1 Germany. (a) Consumers can terminate a paid Plan through the cancellation button (“Verträge hier kündigen”) available on every page of the dashboard, which leads to a confirmation page and an acknowledgement by email with date and time (§312k BGB). (b) For consumers, after the initial term a yearly Plan continues for an indefinite period and may be terminated at any time with one month’s notice; Section B.6 applies to refunds. (c) We do not participate in dispute resolution before a consumer arbitration board (§36 VSBG). (d) Our Legal Notice contains the information required by §5 DDG.
D.2 United States. For US customers: (a) Plans renew automatically as described in Section 4.3; you consented to the renewal terms when ordering and received a confirmation email; you can cancel online at any time through the same dashboard you used to subscribe; for yearly Plans we send a reminder 30 days before renewal. (b) Sales tax is added where we are required to collect it. (c) Nothing in these Terms limits rights under the law of your state that cannot be waived. (d) California residents: see the “US State Privacy Rights” section of our Privacy Policy.
