Terms of Use
I. Effective date
Updated on 7 June 2026.
By accessing Blekline, creating an account, installing or using the Blekline browser extension, connecting an MCP client, using our APIs, or placing an order for a paid subscription, you confirm that you agree to and are bound by these Terms & Conditions. These terms apply to the Blekline marketing website, web application, browser extension, MCP server and connectors, APIs, ingress proxy or sidecar components, documentation, and any email or other communication between you and us regarding Blekline.
II. Agreement
These Terms of Use are a contract between you and The Wall d.o.o. (referred to as “The Wal*”, “we”, “us” or “our”), the provider of the Blekline Services (defined below). If you do not agree to these Terms of Use, do not use the Services.
In these Terms of Use, “You” means you as an individual and, where applicable, the company or other legal entity you represent. If you breach these Terms of Use, we may suspend or terminate your access or account without notice, where permitted by law.
III. Corporate structure
Blekline is provided by The Wall d.o.o. (“The Wall”, “we”, “us”, “our”), a private limited company incorporated in the **Republic of Slovenia** (Mestni trg 10, 1000 Ljubljana, Slovenia).
The Wall d.o.o. is the legal entity that owns and operates Blekline worldwide. In English, *d.o.o.* (*družba z omejeno odgovornostjo*) is a private limited company — the Slovenian equivalent of a “Ltd” in the United Kingdom or a “LLC” in the United States. There is no separate UK company; references to “The Wall” or “we” mean The Wall d.o.o.
Slovenščina: Storitve Blekline zagotavlja The Wall d.o.o., Mestni trg 10, 1000 Ljubljana, Slovenija.

V. License to use the Services
Subject to these terms and your payment obligations (if any), we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Services for your internal business or personal purposes in accordance with your plan and documentation.
You must not: (a) sublicense, sell, rent, lease, distribute, or commercially exploit the Services except as expressly permitted; (b) use the Services to build a competing product or service; (c) probe, scan, or test the vulnerability of our systems without authorisation; (d) interfere with or disrupt the integrity or performance of the Services; (e) bypass or disable security, masking, or policy controls.
VI. Accounts, security, and acceptable use
You are responsible for maintaining the confidentiality of your credentials, workspace tokens, and API keys, and for activity under your Account. You must provide accurate registration information.
You agree not to, and not to permit others to: (a) use the Services unlawfully or in a way that infringes third-party rights; (b) attempt to gain unauthorised access to other users’ data, our systems, or third-party systems; (c) transmit malware or harmful code; (d) overload or attack the Services; (e) use the Services to send spam or unsolicited marketing without consent; (f) submit content you do not have the right to process.
We may suspend or restrict access if we reasonably believe you have violated these rules or pose a security risk.
VII. Restrictions
You agree not to, and you will not permit others to:
- License, sell, rent, lease, assign, distribute, transmit, host, outsource, disclose, or otherwise commercially exploit the Services except as these terms allow.
- Modify, create derivative works of, disassemble, decrypt, reverse compile, or reverse engineer any part of the proprietary SaaS Services, except to the extent mandatory law permits or except for open-source components governed by their own licence (Section VIII).
- Remove, alter, or obscure any proprietary notices (including copyright or trademark notices) of The Wall or its licensors.
VIII. Open-source software
Certain Blekline components may be offered under open-source licences (including **AGPL-3.0**) via our public repositories. Open-source components are **not** part of the proprietary SaaS licence in Section V and are governed solely by their applicable open-source licence.
Use of open-source packages does not grant rights to the hosted Blekline platform, enterprise features, or support unless separately agreed. We provide open-source software **without warranty** to the extent permitted by the applicable licence.
IX. MCP, Extension, and third-party AI clients
Extension: The Extension operates on supported AI web applications to apply workspace policy before content is sent. Host permissions are limited to supported sites and Blekline infrastructure as described in store listings and documentation.
MCP Services: MCP tools (e.g. `blekline_mask_prompt`, `blekline_evaluate_tool_call`) integrate with third-party AI clients. You are responsible for configuring clients securely and for compliance with each client’s terms.
Third-party AI tools and sandboxes: Blekline governs ingress to models and tools you connect; we do not control third-party models, sandboxes, or downstream MCP servers. You remain responsible for your use of those services and for data you send outside Blekline.
No guarantee of detection: Masking and policy enforcement are technical controls. They do not guarantee detection of all sensitive data and are not a substitute for legal, regulatory, or compliance advice.
X. Subscriptions, billing, trials, and refunds
Paid features may require a **Subscription** processed by a third-party payment provider (e.g. **Stripe**). By subscribing, you agree to that provider’s terms and our pricing presented at checkout. Invoices are issued by **The Wall d.o.o.**
**Trials and tryouts:** We may offer time-limited trials, tryouts, or usage-limited access (including without a payment card). Features and limits are described in the product or checkout flow. We may change or end trial programmes.
**Billing:** Fees are charged in the currency and cycle shown at purchase unless otherwise stated. Taxes may apply. Failed payments may result in suspension of paid features.
**Refunds:** Statutory rights apply where they cannot be waived. Otherwise, refund eligibility depends on your plan, jurisdiction, and what was presented at purchase. If you are not satisfied, contact us at the address in Section XXXV and we will review your case in good faith. Chargebacks may result in account suspension.
**Cancellation:** You may cancel according to the billing portal or instructions in the app. Cancellation stops future renewals; access may continue until the end of the paid period unless stated otherwise.
XI. EU consumers
If you are a consumer habitually resident in the European Union or United Kingdom, mandatory consumer protection laws of your country may apply in addition to these Terms.
Where applicable law grants a right of withdrawal for distance contracts, you may have 14 days from purchase to withdraw without giving reasons, subject to exceptions for digital content that has begun with your consent. Contact us at hello@blekline.com for withdrawal requests.
Online dispute resolution (EU): The European Commission provides an ODR platform: [https://ec.europa.eu/consumers/odr/](https://ec.europa.eu/consumers/odr/). We are not obliged to participate in alternative dispute resolution but will respond to lawful consumer inquiries in good faith.
XII. Your consent
By using our Website, registering an Account, using the Extension or MCP Services, or purchasing a Subscription, you consent to these Terms of Use and to our Privacy Policy and Cookie Policy (published at https://blekline.com/privacy and https://blekline.com/cookies), which describe how we process personal data and cookies.
XIII. Third-party websites and integrations
The Services may contain links to third-party sites or allow integrations with third-party products (including AI tools, identity providers, payment processors, or data sources). We do not control and are not responsible for third-party content, practices, or terms. Your use of third-party services is at your own risk and subject to their terms. When you leave our Services, these Terms of Use no longer govern that site or service.
XIV. Cookies
We use cookies and similar technologies as described in our [Cookie Policy](./BLEKLINE_COOKIE_POLICY.md). Non-essential cookies and scripts on the marketing site require consent where required by law. You can control cookies through our consent manager or your browser settings; disabling essential cookies may limit core features (e.g. staying signed in).
XV. Changes, suspension, and availability
We may modify, suspend, or discontinue the Services (or any feature) at any time, with or without notice, where permitted by law. We do not guarantee uninterrupted or error-free operation. Planned maintenance may cause downtime.
We may change these Terms of Use by posting an updated version and updating the effective date. Where required by law, we will provide additional notice. Continued use after changes constitutes acceptance unless you stop using the Services and, where applicable, cancel your Subscription.
XVI. Modifications to the Services
We may enhance, patch, or update the Services. Updates may change or remove features. We are not obliged to provide any specific feature indefinitely.
XVII. Third-party services (infrastructure and payments)
We may display or enable third-party content, APIs, or links (“Third-party services”). We are not responsible for Third-party services, including their accuracy, legality, or availability. Third-party services are provided as a convenience; you use them at your own risk under the third party’s terms. A current list of subprocessors is in our [Subprocessor List](./BLEKLINE_SUBPROCESSORS.md).
XVIII. Term and termination
These Terms of Use remain in force until terminated. You may terminate by closing your Account where the product allows, or by ceasing use and cancelling your Subscription. We may suspend or terminate your access or these Terms of Use at any time if you breach them, if we must comply with law, or for operational reasons, with or without notice where permitted.
Upon termination, your right to use the Services ceases. Provisions that by nature should survive (including intellectual property, disclaimers, limitation of liability, indemnity, and governing law) will survive.
XIX. Waiver
Failure to enforce any right or provision is not a waiver. No waiver is effective unless in writing and signed by an authorised representative of The Wall (where required).
XX. Copyright and trademark complaints
If you believe material on our Services infringes your copyright, contact us with: (a) identification of the work; (b) identification of the allegedly infringing material; (c) your contact details; (d) a good-faith statement that the use is not authorised; (e) a statement of accuracy under penalty of perjury where applicable; and (f) your signature (physical or electronic).
XXI. Indemnification
To the extent permitted by law, you agree to indemnify and hold harmless The Wall d.o.o. and its affiliates, officers, agents, and employees from claims, damages, losses, and expenses (including reasonable legal fees) arising out of: (a) your use of the Services; (b) your breach of these terms or applicable law; or (c) your violation of third-party rights.
XXII. No warranties
THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
We do not warrant that the Services will meet your requirements, be uninterrupted, timely, secure, or error-free, or that data will be accurate or loss-free. We do not warrant that the Extension, MCP integrations, or third-party clients will work with every site, model, or browser version.
Not legal or compliance advice: Blekline helps you manage how data is handled in workflows involving AI tools; it is not legal, regulatory, or compliance advice. You remain responsible for your own legal obligations and for how you configure and use the Services.
Some jurisdictions do not allow certain disclaimers; in those cases, disclaimers apply to the fullest extent permitted.
XXIII. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW:
- OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATED TO THE SERVICES OR THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) ONE HUNDRED EUROS (€100) IF NO FEES WERE PAID.
- WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS INTERRUPTION, EVEN IF ADVISED OF THE POSSIBILITY.
Mandatory consumer rights under the law of your country (including the EU) may not be excluded; nothing in these terms limits those non-waivable rights.
XXIV. Severability
If any provision is invalid or unenforceable, the remainder remains in effect and the invalid provision will be modified to reflect the parties’ intent as far as possible.
XXV. Governing law and disputes
These Terms of Use are governed by the laws of the Republic of Slovenia, without regard to conflict-of-law rules, except that if you are a consumer habitually resident in the European Union or United Kingdom, you may benefit from mandatory provisions of the law of your country of residence, and nothing in these terms deprives you of those protections.
Subject to mandatory law, the courts of Ljubljana, Slovenia shall have jurisdiction for disputes arising from these terms, except that consumers may bring proceedings in their home courts where EU/UK consumer law so requires.
We encourage you to contact us first (Section XXXV) to resolve disputes informally.
XXVI. Amendments
We may modify these terms. We will post the updated terms and the new effective date. Where we are required to give advance notice (e.g. for material changes under consumer law), we will do so. Continued use after the effective date constitutes acceptance.
XXVII. Entire agreement
These Terms of Use, together with the Privacy Policy, Cookie Policy, any plan-specific terms presented at purchase, and any applicable Data Processing Agreement for business customers, constitute the entire agreement regarding Blekline and supersede prior agreements on the same subject, except where mandatory law requires otherwise.
XXVIII. Intellectual property
The Services, including software, text, graphics, logos, and layout, are owned by The Wall or its licensors and are protected by copyright, trademark, and other laws. Except for the limited licence in Section V and open-source licences in Section VIII, no rights are granted. “Blekline” and related marks are trademarks of The Wall or its affiliates. You may not use our marks without prior written consent.
XXIX. Feedback
If you send us feedback, suggestions, or ideas about the Services, you grant us a perpetual, irrevocable, royalty-free licence to use them to improve and promote the Services without obligation to you, unless we agree otherwise in writing.
XXX. Promotions
Contests or promotions may have separate rules. If you participate, those rules apply in addition to these terms.
XXXI. Pricing and description errors
If a price or feature description is clearly incorrect due to error, we may refuse or cancel the relevant order or Subscription and refund any amount charged, or offer correction.
XXXII. Data protection
Processing of personal data is described in our Privacy Policy. Where we process personal data on behalf of your organisation, a separate Data Processing Agreement may apply if required by law — see [BLEKLINE_DPA_OUTLINE.md](./BLEKLINE_DPA_OUTLINE.md) or contact us for enterprise terms.
XXXIII. Export and sanctions
You may not use or export the Services in violation of applicable export control or sanctions laws.
XXXIV. Miscellaneous
If any provision is held unenforceable, the rest remains in effect. Headings are for convenience only. You may not assign these terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
