Terms and Conditions

Effective date: 25 August 2026
Version: 1.0

These Terms of Service (the “Terms”) form a legally binding agreement between you and Basilai Limited, a company incorporated in Hong Kong with company number 79082001 and business registration number 79082001, whose registered office is at Unit D, 12/F Seabright Plaza, 9–23 Shell Street, North Point, Hong Kong (“Basil,” “we,” “us,” or “our”).

These Terms govern your registration for and use of Basil’s consumer software-as-a-service products, websites, applications, and related services made available through aos.work, basilos.ai, and any other location that links to these Terms (collectively, the “Service”).

Please read these Terms carefully. By creating an account, purchasing a subscription, accepting an invitation to an organisation workspace, or using the Service, you agree to these Terms. If you do not agree, do not create an account, purchase a subscription, accept an invitation, or use the Service.

1. Who may use the Service

1.1 Age requirement

You must be at least 18 years old and legally capable of entering into a binding contract to use the Service. The Service is not directed to children. You must not create an account for, permit access by, or submit personal data relating to a person under 18 for the purpose of enabling that person to use the Service.

1.2 Accounts and organisation workspaces

Each account is for one individual user. You must provide accurate, current, and complete registration information and keep it updated. You must not sell, transfer, rent, share, or make your account credentials available to another person.

You are responsible for activity conducted through your account to the extent caused by your acts or omissions. You must notify us promptly at security@basilos.ai if you suspect unauthorised access to your account.

If you purchase or administer a Team or Enterprise subscription for an organisation, you represent that you are authorised to act for that organisation. The organisation is responsible for paying for its seats, assigning seats only to authorised users, managing its workspace, and ensuring that its administrators and invited users comply with these Terms. An administrator may manage access to the organisation workspace and content held in that workspace. Each invited user remains responsible for their own conduct.

1.3 Personal and professional use

You may use the Service for lawful personal, professional, educational, charitable, or internal business purposes. The hosted Service does not include private deployment, a negotiated service-level agreement, regulated-industry commitments, or bespoke implementation services unless Basil expressly agrees otherwise in writing. Private deployment and bespoke enterprise services require a separate written agreement.

2. The Service

2.1 Service features

Depending on your plan, location, device, and the availability of third-party services, the Service may include:

• artificial intelligence chat and task execution;

• file upload, storage, processing, generation, preview, and download;

• generated files, links, and other task outputs (“Outputs”);

• memory features that retain information to support future interactions;

• skills, tools, workflows, and other reusable capabilities (“Skills”);

• connections to third-party products and accounts (“Connectors”);

• scheduled tasks and automated execution; and

• access to models and services supplied by third-party providers.

Specific features, limits, supported formats, model availability, and Credits are described in the Service, on the applicable plan page, or at checkout. A reference to a planned, preview, beta, or future feature does not promise that the feature will be released or remain available.

2.2 Hosted SaaS only

These Terms apply to the hosted Personal, Team, and Enterprise plans described in Section 8. They do not apply to private deployments, bespoke enterprise implementations, managed services, or services supplied under a separate order form or enterprise agreement. If a separate written agreement applies to a service, that agreement controls for that service.

2.3 Technical requirements

You are responsible for obtaining a compatible device, software, internet connection, and any third-party accounts required to use the Service. We may publish reasonable technical, security, file-format, and usage requirements from time to time.

3. AI features and Outputs

3.1 Nature of AI results

The Service uses probabilistic artificial intelligence systems. Outputs may be inaccurate, incomplete, outdated, offensive, biased, or unsuitable for your purpose. Similar or identical Outputs may be generated for other users. You must review and verify Outputs before relying on, publishing, sharing, or acting on them.

3.2 No professional advice or high-impact reliance

The Service and Outputs do not constitute medical, legal, financial, tax, accounting, employment, insurance, credit, or other professional advice. You must not use the Service or an Output as the sole basis for a decision that may materially affect a person’s rights, health, safety, employment, education, access to essential services, legal position, or financial circumstances.

Where appropriate, you must obtain qualified professional advice and meaningful human review.

3.3 External actions

Some Skills, Connectors, and scheduled tasks may take actions in third-party services. You are responsible for reviewing the requested permissions, configuration, recipients, scope, and consequences before authorising a Connector or automated action. You may only connect accounts and data that you are authorised to access.

We will not intentionally install a Connector, authorise a third-party account, or change a Connector binding without an action or confirmation attributable to you. You remain responsible for instructions and permissions you provide and for reviewing significant external actions.

3.4 Output rights

As between you and Basil, and to the extent permitted by applicable law, Basil does not claim ownership of Outputs generated specifically for you. We assign to you any right, title, or interest we may have in those Outputs, subject to:

• your compliance with these Terms;

• any rights in your Input or third-party material;

• applicable law; and

• any terms that apply to a third-party model, Connector, Skill, or content source.

Because AI Outputs may not be unique and may not qualify for intellectual property protection, we do not warrant that you can obtain or enforce exclusive rights in an Output or that an Output will not resemble material generated for another person.

4. Your content

4.1 Your rights

You retain your rights in prompts, messages, files, instructions, configurations, and other material you submit to the Service (“Input”). Input and Outputs are together referred to as “User Content.”

4.2 Licence needed to provide the Service

You grant Basil and its service providers a worldwide, non-exclusive, limited licence to host, copy, transmit, process, display, modify, and otherwise use User Content only as reasonably necessary to:

• provide and operate the Service at your request;

• generate Outputs and execute tasks;

• maintain security, prevent abuse, and investigate incidents;

• provide support and resolve technical problems;

• comply with applicable law and valid legal process; and

• enforce these Terms.

This licence lasts only for as long as reasonably necessary for those purposes, subject to applicable retention requirements, backup cycles, and the Privacy Notice.

4.3 Model training

We will not use your User Content to train a general-purpose AI model unless you separately and expressly opt in. This does not prevent us from using service telemetry, security signals, feedback, or aggregated or de-identified information that does not identify you or reveal your User Content to maintain, secure, analyse, and improve the Service, as further described in the Privacy Notice.

4.4 Your responsibilities

You represent that you have the rights and permissions necessary to submit User Content and instruct us to process it. You must not submit content that infringes another person’s rights or that you are prohibited from disclosing.

Unless expressly supported and appropriately protected by the Service, you should not submit government identification numbers, payment card data, passwords, authentication secrets, health records, highly sensitive personal data, or information subject to professional secrecy or special regulatory restrictions.

5. Acceptable use

You must not use the Service to:

1. violate any applicable law or another person’s rights;

2. commit, facilitate, or conceal fraud, deception, impersonation, harassment, exploitation, or unlawful discrimination;

3. create, distribute, or facilitate child sexual abuse material or the sexual exploitation of any person;

4. generate or distribute unlawful violent, hateful, or extremist material;

5. develop, deploy, transmit, or assist malware, credential theft, phishing, denial-of-service attacks, unauthorised access, or other harmful cybersecurity activity;

6. collect, infer, expose, or process personal data without a lawful basis or required permission;

7. send spam, unsolicited bulk communications, or automated messages in breach of applicable law;

8. bypass access controls, safety measures, Credits, rate limits, geographic restrictions, or usage restrictions;

9. probe, scan, test, reverse engineer, decompile, or attempt to extract models, source code, system prompts, non-public data, or security mechanisms, except to the limited extent that applicable law expressly permits and does not allow that permission to be excluded;

10. resell, sublicense, rent, share, or commercially provide access to your account or an assigned seat;

11. interfere with the integrity, availability, or security of the Service or any third-party service;

12. use the Service or Outputs as the sole basis for a high-impact decision described in Section 3.2; or

13. help another person do any of the above.

We may apply proportionate technical and organisational measures to prevent abuse, protect users and third parties, and comply with law.

6. Connectors and third-party services

Connectors, models, Skills, links, payment services, and other third-party products are provided by independent third parties and may be subject to separate terms and privacy notices. Your use of a third-party service is between you and that provider.

We do not control and do not promise the continued availability, accuracy, security, or performance of a third-party service. A third party may change, restrict, suspend, or discontinue its service. To the extent permitted by law, Basil is not responsible for loss caused solely by a third-party service outside our reasonable control. Nothing in this Section excludes responsibility that cannot lawfully be excluded.

When you disconnect a Connector, we will stop new access through that connection, but the third-party provider and Basil may retain information already processed as described in their applicable notices and retention rules.

7. Plans and Credits

7.1 Plan limits

Your plan may include limits based on Credits, models, tasks, storage, files, execution time, rate limits, or other measurements. Current plan details are displayed before purchase or within the Service.

7.2 Credits

Where a plan includes usage Credits:

• subscription Credits reset at the interval stated for the plan;

• unused subscription Credits do not roll over;

• Credits have no cash value, are non-transferable, and cannot be exchanged for money;

• Credits associated with a subscription expire when the subscription ends;

• Credits are internal units used only to measure access to Service features and are not a payment instrument, stored value, electronic money, cryptocurrency, or property; and

• once available Credits are exhausted, the relevant functionality may stop or be limited until Credits reset.

We will not impose an overage charge merely because you have exhausted your Credits. We do not currently sell Credits separately. Any future separately chargeable purchase must be clearly disclosed and separately authorised before charge.

7.3 Measurement

Our reasonable service records determine Credit use, subject to correction of demonstrated errors. Different models, Skills, Connectors, tasks, or operations may consume different amounts of Credits where disclosed in the Service.

8. Subscriptions, payment, and taxes

8.1 Paid subscriptions

The Service has no free plan and no free trial. The following standard subscription prices apply from the effective date of these Terms. “$” means United States dollars (USD).

The price charged for a Team or Enterprise subscription is based on the number of paid seats shown and authorised before purchase. The selected plan, seat count, billing interval, currency, included features, Credits or other usage limits, applicable taxes, and total charge will be displayed before you place your order. If the pricing page and checkout display a lawful promotional price or another currency, the specific price and currency expressly accepted at checkout govern that purchase.

Paid access is supplied electronically and normally becomes available immediately after successful payment and account activation. There are no physical goods, shipping, or returns.

8.2 Stripe

Payments are processed by Stripe or its affiliates. You authorise Basil and Stripe to charge your selected payment method for the initial term, recurring renewal fees, applicable taxes, and any separately authorised purchase. Stripe’s own terms and privacy notice apply to its processing of payment information.

We do not store complete payment card details.

8.3 Taxes and currency

The standard prices in Section 8.1 are in USD. Unless the pricing page expressly states that tax is included, those standard prices are before any applicable VAT, sales tax, goods and services tax, or similar tax. Before you place the order, the final order summary will show the purchase currency, applicable taxes and mandatory charges, and the total amount due as required by law. Where consumer law requires a tax-inclusive advertised price, the tax-inclusive price displayed to you governs. You are responsible only for amounts clearly disclosed before you place the order, except where a later change is required by law or separately authorised by you.

8.4 Automatic renewal

Personal and Team subscriptions automatically renew monthly, and Enterprise subscriptions automatically renew annually, unless a different interval is expressly shown at checkout or you cancel before the renewal date. By subscribing, you authorise recurring charges to your selected payment method for the applicable subscription and seat count.

We will provide renewal information and reminders where required by applicable law. You are responsible for keeping your payment information current.

For an organisation plan, an administrator may add or remove seats through the Service where that feature is available. Any charge for added seats, and the date on which a seat reduction takes effect, will be shown before the administrator confirms the change. We will not charge for a seat change that was not authorised through the applicable purchase flow.

8.5 Cancellation

You may cancel automatic renewal at any time through the account or billing settings made available in the Service. Cancellation takes effect at the end of the current paid billing period. Unless required by law or expressly stated otherwise, you will retain access until that date and will not receive a prorated refund for the unused portion of the period.

If self-service cancellation is unavailable because of a technical problem, contact support@basilos.ai before the renewal date. We will not require you to use a cancellation method materially more burdensome than the method used to subscribe.

8.6 Price changes

We may change subscription prices for a future renewal. We will give at least 30 days’ advance notice of a price increase that materially affects you, unless a shorter period is required by law, tax, or an urgent regulatory change. A price increase will not apply retroactively to a period already paid. You may cancel before the new price takes effect.

8.7 Failed payments

If a payment fails, we may retry the charge, ask you to update your payment method, restrict paid functionality, or suspend the subscription after any notice or grace period required by law. You remain responsible for valid, disclosed charges incurred before cancellation or suspension.

9. Withdrawal and refunds

9.1 Statutory withdrawal rights

If you purchase as a consumer and applicable law gives you a cooling-off or withdrawal right, you may exercise it within the applicable period. For consumers in the European Union or European Economic Area, this period is generally 14 days from conclusion of the subscription contract, subject to applicable exceptions and national law.

Because paid access is normally supplied immediately, the checkout may ask you to expressly request performance during the withdrawal period and acknowledge the legal consequences. We will provide the contract confirmation on a durable medium, such as email.

If you withdraw after expressly requesting that the Service begin during the withdrawal period, we may deduct or charge a proportionate amount for the Service supplied before withdrawal, but only to the extent permitted by applicable law. If a service has been fully performed, or separately supplied digital content has begun to be supplied, a withdrawal right may be lost only where all legally required request, consent, acknowledgement, and confirmation conditions are satisfied.

9.2 How to withdraw

You may exercise a statutory withdrawal right by sending a clear statement to legal@basilos.ai or support@basilos.ai before the withdrawal period expires. You may use the model form in Annex 1, but use of that form is not mandatory.

9.3 Refund timing

Where a refund is legally due, we will issue it using the original payment method without undue delay and within the period required by applicable law. For a valid EU or EEA withdrawal, this is generally no later than 14 days after we are informed of the decision to withdraw. Processing time at your bank or payment provider may be outside our control.

9.4 Other refunds

Except for statutory rights, duplicate or erroneous charges, a material failure to supply the Service, or another refund expressly promised at checkout, fees are non-refundable. Suspension or termination for serious unlawful, fraudulent, abusive, or security-threatening conduct is non-refundable to the extent permitted by law.

Nothing in this Section limits remedies you have for a digital service that is not supplied or does not conform to mandatory consumer law.

10. Service availability and changes

10.1 No consumer SLA

The hosted Service does not include a contractual uptime percentage, enterprise service-level agreement, guaranteed response time, or service credits. We will provide the Service with the care and skill required by applicable law.

The Service may be unavailable because of maintenance, upgrades, capacity limits, third-party failures, network conditions, security incidents, force majeure events, or other operational reasons.

10.2 Changes to features

We may improve, modify, replace, limit, or discontinue features for valid reasons, including security, legal compliance, technical requirements, third-party changes, service improvement, and adaptation to user demand. We will not materially reduce the core functionality of a paid subscription during its current paid period without an appropriate remedy where required by law.

Where reasonably practicable, we will provide at least 30 days’ notice on a durable medium before discontinuing or materially changing a paid feature. If a modification negatively affects your access to or use of the Service beyond a minor degree, you may terminate the affected subscription free of charge within 30 days after receiving notice or after the modification takes effect, whichever is later, where applicable consumer law gives you that right. In that case, we will provide any required pro-rata refund. We may make immediate changes where necessary for security, legal compliance, abuse prevention, third-party availability, or protection of users.

10.3 Beta and preview features

Features labelled beta, preview, experimental, early access, or similar may be incomplete, change without notice, and be subject to additional limits. We will identify material limitations where reasonably possible. Mandatory consumer rights continue to apply.

11. Suspension and termination

11.1 Suspension by Basil

We may proportionately restrict or suspend access where reasonably necessary because:

• you have materially or repeatedly breached these Terms;

• payment is overdue or reversed;

• your use creates a credible security, legal, or operational risk;

• we reasonably suspect fraud, unlawful conduct, or serious abuse;

• a third-party service required for the feature is unavailable; or

• suspension is required by law or a competent authority.

Where appropriate and lawful, we will notify you and provide a reasonable opportunity to remedy an ordinary breach. We may act immediately in urgent or serious cases.

11.2 Termination by you

You may stop using the Service and cancel renewal at any time. Deleting your account and cancelling a subscription are separate actions unless the Service clearly states otherwise. You should cancel the subscription before deleting the account to prevent a future renewal charge.

11.3 Termination by Basil

We may terminate these Terms or your account for an unremedied material breach, serious or repeated abuse, fraud, unlawful conduct, a significant security threat, or where continued provision is unlawful or no longer reasonably possible.

If we discontinue the hosted Service for reasons unrelated to your breach, we will provide reasonable advance notice where practicable and any refund or remedy required by law.

11.4 Data retrieval and deletion

Following termination, we will ordinarily provide up to 30 days for you to retrieve exportable User Content, unless access is prohibited by law, creates a security risk, is technically unavailable, or your account was terminated for serious abuse. After the retrieval period, we may delete or de-identify User Content in accordance with our Privacy Notice, legal retention duties, and backup cycles.

You are responsible for exporting User Content you wish to retain. We do not promise indefinite storage.

12. Intellectual property in the Service

The Service, including its software, interfaces, designs, branding, documentation, models owned by Basil, workflows, and underlying technology, is owned by Basil or its licensors and is protected by intellectual property laws.

Subject to these Terms, Basil grants each authorised user a limited, non-exclusive, non-transferable, revocable right to access and use the hosted Service during the applicable subscription solely for permitted purposes. No other rights are granted.

“Basil,” Basil logos, and related marks are trademarks of Basil or its licensors. You may not use them in a way that suggests endorsement, partnership, or affiliation without written permission.

If you voluntarily submit feedback, you permit us to use it without restriction or payment, provided we do not publicly identify you as its source without permission.

13. Privacy

Our separate Privacy Notice, presented through the Service and our websites, explains how Basil collects, uses, shares, stores, transfers, and protects personal data and how you may exercise applicable privacy rights. The Privacy Notice is not part of these Terms and does not reduce any right you have under applicable data protection law. Privacy questions and rights requests may be sent to privacy@basilos.ai.

Information about cookies and similar technologies is presented through the website’s cookie notice or consent interface. Where consent is required, non-essential cookies will not be used unless and until you make the appropriate choice.

14. Consumer guarantees and disclaimers

14.1 Mandatory rights preserved

Nothing in these Terms excludes, restricts, or changes a guarantee, warranty, remedy, or other consumer right that applicable law does not allow us to exclude, restrict, or change.

14.2 Disclaimer to the extent permitted by law

Subject to Section 14.1, the Service is provided on an “as available” basis. We do not promise that the Service will be uninterrupted, error-free, completely secure, compatible with every system, or suitable for every purpose. We do not warrant the accuracy, uniqueness, legality, or non-infringement of an AI Output.

You are responsible for reviewing Outputs, maintaining appropriate copies of important information, and deciding whether the Service is suitable for your intended use.

15. Liability

15.1 Liability that is not limited

Nothing in these Terms excludes or limits liability to the extent it cannot lawfully be excluded or limited, including liability for fraud or fraudulent misrepresentation, or for death or personal injury caused by negligence where applicable law prohibits such a limitation.

15.2 Types of loss

To the extent permitted by applicable law, Basil is not liable for indirect or consequential loss, loss of profit, loss of business opportunity, loss of anticipated savings, or loss caused solely by your failure to follow these Terms, verify an Output, maintain appropriate backups, or secure your account.

This exclusion does not apply where such loss was reasonably foreseeable under mandatory consumer law or where exclusion is otherwise prohibited.

15.3 Liability cap

To the extent permitted by applicable law, Basil’s total aggregate liability arising out of or relating to the Service or these Terms will not exceed the total fees paid to Basil for the affected hosted Service during the 12 months immediately preceding the event giving rise to the claim.

This cap does not apply to liability identified in Section 15.1 or to any liability that applicable consumer law does not allow us to cap.

16. Complaints and disputes

16.1 Contact us first

If you have a complaint, contact support@basilos.ai and provide your account email, a description of the issue, and the remedy you seek. We will attempt to resolve the complaint in good faith.

16.2 Governing law

These Terms are governed by the laws of Hong Kong. If you are a consumer, this choice does not deprive you of the protection of mandatory provisions of the law that would apply in your country of habitual residence in the absence of this choice.

16.3 Courts

Subject to your mandatory consumer rights, the courts of Hong Kong have non-exclusive jurisdiction over disputes arising from these Terms or the Service. You may bring proceedings in the courts of your country of habitual residence where applicable law permits or requires, and Basil may bring proceedings against you only in a court permitted by applicable consumer law.

17. Changes to these Terms

We may update these Terms to reflect changes to the Service, law, regulation, security, third-party services, or our business.

For a change that materially disadvantages you, we will normally provide at least 30 days’ advance notice by email, an in-product notice, or another durable method. You may cancel your subscription before the change takes effect. Where mandatory consumer law gives you a right to terminate because of the change, termination will be free of charge and we will provide any refund required by law. A change required urgently for law, security, abuse prevention, or protection of users may take effect sooner, with notice where reasonably practicable.

Changes will not retroactively remove a right or remedy that has already accrued. The effective date and current version will be displayed at the beginning of these Terms.

18. General terms

18.1 Electronic communications

You agree that we may provide contractual information, receipts, notices, and service communications electronically, including by email or through the Service. We will provide information in a form you can save where required by law.

18.2 Assignment

You may not transfer these Terms or your account to another person. We may transfer these Terms as part of a merger, reorganisation, financing, sale of business, or transfer to an affiliate, provided the transfer does not reduce your mandatory consumer rights. We will notify you where required by law.

18.3 Severability

If a provision of these Terms is found unenforceable, it will be interpreted or limited to the minimum extent necessary, and the remaining provisions will continue in effect. This does not permit us to replace an unfair consumer term with another term that produces substantially the same unfair result.

18.4 No waiver

A failure or delay in enforcing a provision is not a waiver of that provision or any other right.

18.5 Entire agreement and order of precedence

These Terms, the information presented at checkout, and any additional terms expressly accepted for a feature form the agreement governing the hosted Service. If they conflict, the checkout information controls for the specific plan, price, currency, billing interval, seat count, Credits, and purchase, while these Terms control for general use of the Service, unless mandatory law requires otherwise.
