Platform Terms of Use
These Terms are the agreement between you and One Horizon BV. They apply when you create an account, use One Horizon, or pay for a plan. Please read them before you sign up.
1. Who we are and who these Terms cover
One Horizon is a work platform at onehorizon.ai. Teams define how work should be done as reusable workflows, delegate that work to AI agents, and keep people in the loop through review and approval steps. Agents can run through external model providers or on hardware you control, and One Horizon connects to the delivery and collaboration tools you already use.
One Horizon is not itself a coding agent. It orchestrates the agents and people doing the work, and keeps a record of what happened.

These Terms cover both businesses and consumers. Where the law gives consumers rights that these Terms cannot limit, those rights apply and the rest of these Terms stay in force.
If you sign up for an organisation, you confirm you are allowed to accept these Terms for it. In that case "you" means both you and that organisation.
Enterprise customers contract with us directly. A signed enterprise agreement takes precedence over these Terms for anything it covers, such as billing, service levels, liability, data protection, or security. These Terms apply to everything the signed agreement leaves open.
Our Privacy Policy forms part of this agreement and explains how we handle personal data. The data processing agreement at the end of these Terms applies when we process personal data for you.
Questions about these Terms: Send us a message.
2. Your account
You must be at least 18 and able to enter into a contract. You need to register with accurate contact details and keep them current.
You are responsible for your account and for everything done through it. That includes sign-in through Google, GitHub, Apple, or Slack.
We never hold your password at those providers and can't reset it for you. Keep that account secure, turn on the protections it offers, and tell us through Send us a message the moment you think someone else has access.
We do not settle disputes about who owns an account. Where several people claim the same account, we rely on the registered contact and billing details.
3. Plans, payment, and tax
Plans. There's a free plan and there are paid plans. Current prices and limits are on our pricing page.
What you pay. Before you confirm, checkout shows your plan, seats, billing interval, currency, any trial, and the final amount including tax. That screen sets your price for the first billing period. Published prices exclude tax.
Payments. We partner with Stripe to handle all payments. You may need to accept Stripe's own terms when you pay.
Renewal. A paid subscription renews automatically for the same interval until it is cancelled.
Seats and plan changes. Adding seats or upgrading can be charged straight away, prorated for the rest of the period you've paid for. Removing seats or downgrading takes effect at your next renewal.
Price changes. We may change prices. A new price applies from your next renewal, and we will tell you in advance. We never reprice a period you have already paid for.
Failed payments. If a payment fails, we may retry it and ask you to update your payment method. If payment keeps failing, we may suspend the paid plan or move the workspace to the free plan.
Where we sell. We sell where the law and Stripe allow it. We may decline or stop a sale in a country for legal, tax, or payment reasons.
4. Refunds and cancellation
Your first purchase. You can cancel your first paid subscription within 14 days of the first payment and get that payment back in full. This applies to businesses and consumers. It applies once, to that first purchase, and does not start again at renewal.
Monthly plans after the first 14 days. You can cancel at any time. The plan runs until the end of the month you have paid for, and that month is not refunded.
Yearly plans after the first 14 days. You can cancel at any time. Ask us to end the year early and we refund the unused remainder pro rata from the date we process it, with paid access ending that day. Or let the year run out as normal, without a refund.
How to cancel. The billing owner cancels from Settings → Billing, which opens Stripe. For a refund under this section, contact Support.
Cancelling is not deleting. When a paid plan ends, the workspace moves to the free plan where the free plan is available, and existing members and work stay in place subject to free plan limits. Deleting your account or workspace is a separate action described in the Privacy Policy.
Consumers in the EU have a statutory right of withdrawal for distance contracts. Nothing in this section limits that right where it applies.
5. Your content
You own everything you upload, connect, or create in One Horizon. You give us permission to host, process, transmit, and display it, so we can run the service for you and for the people you share it with. That permission ends when the content is deleted, apart from copies kept under the retention rules in the Privacy Policy.
You confirm you have the rights to the content you bring into One Horizon, including content pulled in from services you connect.
Anything you deliberately publish or share outside your workspace is your responsibility. The content standards in section 7 apply to everything you bring into One Horizon, whether you keep it to yourself or share it. We may remove content that breaks these Terms or the law, and we may review content when we need to investigate abuse, a security problem, or a legal request.
If you believe content on One Horizon infringes your intellectual property, tell us through Send us a message with enough detail to identify the content and your rights. We may remove the content and may suspend accounts that infringe repeatedly.
6. AI features and services you connect
One Horizon runs AI agents against your work and includes AI features such as planning, review, summaries, and writing assistance. AI output can be wrong, incomplete, or out of date. That applies to code and any other work an agent produces for you. Review it before you rely on it, and do not treat it as legal, financial, medical, or other professional advice. We do not guarantee any particular result.
We do not use your content to train AI models.
The content standards in section 7 apply to material produced by AI features in the same way they apply to anything else you put into One Horizon.
You choose which external services to connect, such as GitHub, Google, Slack, Jira, Linear, coding agents, and MCP servers. Those services run under your own agreements with their providers, they may process your data outside the EU, and you are responsible for what you connect and what you instruct those services to do. To the extent the law allows, we are not liable for the acts, failures, charges, or data handling of services you choose to connect.
7. Acceptable use and content standards
Security and integrity. Do not use One Horizon to break the law, to harm people, or to attack systems. In particular, do not upload or distribute malware, try to gain unauthorised access to any account or system, interfere with the service or its security controls, send spam or abusive messages, or scrape or resell the service.
Prohibited content. One Horizon is a product for professional work. Do not upload, store, share, publish, or distribute any of the following through it:
- nudity, sexually explicit material, and pornography
- material that sexually exploits or abuses a child
- intimate or sexual imagery of a real person shared without that person's consent
- graphic real-world violence, gore, or the aftermath of a real injury or death
- material that incites, promotes, or glorifies violence, terrorism, or violent extremism
- threats of violence or serious harm against any person
- harassment, bullying, or stalking directed at a person
- content that attacks or degrades people because of race, ethnicity, national origin, religion, caste, sex, gender identity, sexual orientation, disability, or serious illness
- material that encourages or gives instructions for suicide, self-harm, or disordered eating
- instructions for making weapons, explosives, or anything else intended to cause serious physical harm
- content or activity that is illegal under the law that applies to you or to us
Where these rules apply. They apply to everything you put into One Horizon, at every level of visibility. That includes task and initiative titles, descriptions, comments, documents, workspace and profile names, images, video, file attachments, and anything One Horizon sends on to a service you connect. Content you keep to yourself is covered as well as content you share with your workspace, and so is anything the product lets you make available outside your workspace. Keeping the material private does not make it acceptable here, apart from the narrow professional and scientific exception set out below.
AI features. These rules cover material produced by One Horizon's AI features exactly as they cover material you write or upload yourself. Do not use AI features to try to produce anything listed above, and do not keep, share, or distribute AI output that falls under that list.
Professional and scientific exception. Some legitimate work involves material that would otherwise be prohibited: medical and forensic imagery, safety and incident investigation, security research, legal casework, journalism, and academic research.
This exception is limited to four items on the list above, and to nothing else on it:
- nudity, sexually explicit material, and pornography
- graphic real-world violence, gore, or the aftermath of a real injury or death
- suicide, self-harm, and disordered eating
- weapons, explosives, and other things intended to cause serious physical harm
Where the exception applies, the material is allowed only where it genuinely serves work of the kind described above, where it is lawful, and where you limit it to the people who need it for that work. It is not allowed where it is published, circulated, or kept for any other purpose.
Every other item on the list above is prohibited whatever the purpose. No professional, journalistic, research, or investigative claim makes any of them acceptable.
Other terms and laws. You must also comply with the terms of any service you connect and with the laws that apply to the data you bring into One Horizon.
Fair use. We apply reasonable usage and rate limits so the service stays reliable for everyone, including on plan features described as unlimited. We will act proportionately and will not use these limits to avoid what you have paid for.
Reporting a breach. Report content or behaviour that breaks this section through Send us a message on our Support page. Tell us where the content is and what is wrong with it. We do not monitor, scan, or automatically filter the content you put into One Horizon, so reports are how we learn that something here has been broken.
What we do about it. Where we find a breach of this section we may remove the content or disable access to it, and we may suspend or end access under section 12. We act in proportion to how serious the breach is, and where the situation allows we tell you first and give you the chance to put it right. Where someone is at immediate risk, or where the material is child sexual abuse material, we act straight away and report it to the authorities where the law requires it or where reporting is needed to protect someone.
8. Confidentiality
Each of us may receive non-public information from the other. Both of us will keep that information confidential, use it only for this agreement, and protect it with reasonable care. This does not cover information that is already public, that the receiving party already had, or that the law requires to be disclosed.
9. Data protection and compliance
We handle personal data as described in our Privacy Policy, which lists the subprocessors we use.
Where we process personal data on your behalf, we act as processor and you act as controller. The data processing agreement at the end of these Terms applies automatically. You do not need to sign a separate document. Enterprise customers may agree different data processing terms with us.
You are responsible for the lawfulness of the data you put into One Horizon, including having a legal basis for it, giving the people concerned the information they are entitled to, and honouring their rights.
You will use One Horizon in line with the laws that apply to you. You will not use it in breach of applicable sanctions or export controls, and you confirm you are not subject to them.
10. Using your name and logo
If you are on a free plan, we may name you as a customer and show your logo on our website and in presentation material. Tell us through Send us a message or your account settings and we'll remove it within 30 days.
If you are on a paid or enterprise plan, we ask first and only use your name or logo if you agree.
We never publish your usage data, your content, or your business information as part of this.
11. Support, changes, and availability
Free and self-service paid plans come with best-effort support through the channels on our Support page. There is no service level commitment for these plans. Enterprise customers can agree service levels with us.
We keep changing One Horizon, so features change with it. We may add, alter, or withdraw them, and previews and beta features can change or stop at any time.
If we withdraw a feature you paid for and that materially reduces what you bought, you can cancel. That's an ending that isn't your fault, so section 12 applies and we refund the unused part of what you've paid.
We may change the free plan, including its limits.
12. Suspension, termination, and inactivity
You can stop using One Horizon and cancel or delete your account at any time.
We may suspend or end access where it is reasonably necessary, including for serious abuse, a security or legal problem, non-payment, or a material breach of these Terms. Where the situation allows, we tell you first and give you a chance to put it right. For serious abuse or a security or legal risk, we may act immediately.
If we end your paid plan because of something you did, you are not entitled to a refund unless the law says otherwise. If we end it for our own reasons, or for something that is not your fault, we refund the unused part of what you have paid.
If a free workspace has had no workspace or system activity for 12 months, we may delete it and its data after giving the workspace owner reasonable notice. Any workspace or system activity resets that period. We do not delete workspaces with an active paid subscription for inactivity.
13. Warranty position
One Horizon is provided as it is and as available. To the extent the law allows, we do not give warranties that the service will be uninterrupted, error free, or fit for a particular purpose, and we do not warrant the accuracy of AI output.
This does not affect the guarantees consumers have by law, and it does not limit our liability where the law does not allow us to.
14. Liability
Neither of us is liable for indirect or consequential loss, loss of profit, loss of revenue, loss of goodwill, or loss of data beyond the cost of restoring it from your own sources.
Our total liability for all claims under this agreement is limited to the fees you paid us for One Horizon in the 12 months before the event that caused the claim.
Nothing here limits liability for death or personal injury, for intent or wilful recklessness, for fraud, or for anything else that the law does not allow to be limited. If you are a consumer, your mandatory rights come first.
15. Your indemnity
You will cover our losses, including reasonable legal costs, from third-party claims caused by your content being unlawful or infringing, by your misuse of One Horizon, or by unauthorised use of the services you connected.
We do not give an indemnity on free or self-service paid plans. Enterprise customers can agree one with us.
16. Feedback
If you send us ideas or suggestions about the product, we may use them freely and without owing you anything. This gives us no rights over your content, your code, or your data.
17. Changes to these Terms
We may update these Terms. For material changes we give reasonable advance notice by email or in the product. If you keep using One Horizon after a change takes effect, you accept it, unless the law requires us to ask for your consent again. If you do not accept a change, cancel before it takes effect.
18. General
Notices. We contact you at the email address on your account or through the product. You reach us through Send us a message or at our registered address above.
Assignment. You may not transfer this agreement without our written consent. We may transfer it to a group company or in connection with a merger, acquisition, or sale of assets.
Events outside our control. Neither of us is liable for a delay or failure caused by something beyond reasonable control, such as war, natural disaster, industrial action, power or network failure, or the failure of a major third-party provider.
Severability. If any part of these Terms cannot be enforced, the rest stays in force and that part applies to the fullest extent the law allows.
Entire agreement. These Terms, the data processing agreement, the Privacy Policy, and any terms you accept for a specific feature form the whole agreement between us. A signed enterprise agreement prevails over all of them.
Survival. Sections 5, 8, 9, 13, 14, 15, 16, and 18 survive the end of this agreement.
19. Governing law
Dutch law governs these Terms, and the courts of the Netherlands have jurisdiction.
If you are a consumer, this does not take away the protection of the mandatory law of the country where you live, and you may bring proceedings in the courts there. You can also use the European Commission's online dispute resolution platform.
Data processing agreement
This agreement applies where we process personal data on your behalf. You are the controller and we are the processor. Where we decide ourselves why and how personal data is processed, such as for our own account administration, billing, security, and marketing, we act as controller and our Privacy Policy applies instead.
Scope. The subject matter is the provision of One Horizon. Processing lasts for as long as your account is active, plus the retention periods in the Privacy Policy. The nature and purpose are hosting, storing, analysing, summarising, and transmitting the content and account data you bring into the platform, and the integrations you connect. The personal data concerns your team members and anyone whose details appear in the content or the systems you connect. Categories are described in the Privacy Policy.
Our instructions. We process personal data only on your documented instructions, which include these Terms and your use of the product's features. If we think an instruction breaks applicable data protection law, we will tell you without delay and may pause that processing until it is resolved.
Confidentiality. Everyone we allow to process your personal data is bound by confidentiality obligations.
Security. We take appropriate technical and organisational measures under Article 32 GDPR. The measures in place are described on our Security page. We may update them as long as protection is not reduced.
Subprocessors. You give us general authorisation to use subprocessors. The current list is in the Privacy Policy. We will give you notice before adding or replacing one, and you may object on reasonable data protection grounds; if we cannot resolve your objection, you may cancel the affected part of the service. We impose data protection obligations on each subprocessor that are equivalent to those here, and we remain responsible to you for their performance.
Helping you. Taking into account the nature of the processing, we help you respond to requests from individuals exercising their rights, and we help you with data protection impact assessments and prior consultations, using the information reasonably available to us.
Personal data breaches. We notify you without undue delay after becoming aware of a personal data breach affecting your personal data. Where we cannot provide all the details at once, we provide them in phases as the investigation develops.
Deletion or return. When the service ends, we delete or return your personal data at your choice, and delete existing copies unless the law requires us to keep them. Tell us your choice within 30 days of the end of the service; if you do not, we delete the data.
Information and audits. We give you the information you reasonably need to show compliance with Article 28 GDPR, and we allow audits, including inspections, by you or an auditor you appoint. Audits happen at reasonable intervals, on reasonable notice, during business hours, and under confidentiality. We may first offer existing reports and documentation where these answer your questions.
International transfers. We process your data in the EU by default. Where a transfer outside the EEA is needed, we rely on an adequacy decision or on the European Commission's standard contractual clauses, together with any additional measures required.
Enterprise customers. A signed enterprise data processing agreement replaces this one.
