Terms of Service

Last updated: November 14, 2026

These Terms of Service ("Terms") form a binding agreement between you and Aqeeli LLC, in formation as a Delaware limited liability company in the United States ("Aqeeli", "we", "us" or "our"). They govern your use of Context OS: the website at https://contextos.dev, the application at https://app.contextos.dev, the Context OS browser extension, the MCP endpoint, our APIs, and all related features (together, the "Service").

Our Privacy Policy, Refund Policy and Acceptable Use Policy are part of these Terms. By creating an account, buying a plan or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

If you use the Service on behalf of a company or other organization, you confirm that you have authority to accept these Terms for it. In that case, "you" also means that organization.

1. Who we are

Context OS is operated by Aqeeli LLC, in formation as a Delaware limited liability company in the United States. You can reach us at legal@contextos.dev for legal matters and at support@contextos.dev for support.

Postal address: Aqeeli LLC (in formation) — Al-Sanabel District, Jeddah, Kingdom of Saudi Arabia

2. Eligibility

You may use the Service only if:

• you are at least 16 years old, or the age of digital consent in your country if that is higher;
• you can form a binding contract under the law that applies to you; and
• you are not barred from using the Service under the laws of the United States or any other applicable jurisdiction, including sanctions laws (see Section 22).

The Service is not directed to children. If we learn that an account belongs to someone below the required age, we will close it.

3. Your account and security

You must give accurate information when you register and keep it up to date. You are responsible for everything that happens under your account.

Keep your credentials safe. This includes your password, passkeys, two-factor authentication codes, vault API tokens, browser extension tokens and share links. Vault API tokens and share links grant access to vault content without a password, so treat them like passwords and revoke them when you no longer need them. Tell us at support@contextos.dev without delay if you believe your account or a token has been compromised.

If you enable the optional vault passphrase lock, your passphrase is never sent to us. We cannot recover it. If you lose it, locked vault content cannot be decrypted by you or by us.

4. The Service

Context OS turns material you provide into an organized Markdown knowledge base (a "vault"). In particular:

• You can upload AI chat exports (for example from ChatGPT, Claude and Gemini), documents (PDF, DOCX, CSV, HTML and Notion exports), pasted text and voice notes.
• The Service distills them into Markdown files and generates agent routing maps such as AGENTS.md, CLAUDE.md, GEMINI.md, SOUL.md and .cursorrules.
• Your vault can be served to AI tools through our MCP endpoint, through the browser extension on supported AI chat sites (ChatGPT, Claude, Gemini and Grok), and through Vault Chat.
• You can optionally sync your vault to storage you control, such as a GitHub or git repository or an S3-compatible bucket ("bring your own storage" or "BYOS").

The free browser audit runs entirely in your browser. Files you analyze in the audit are not uploaded to us.

5. Plans, prices and payment

5.1 Plans

All prices are in US dollars. Plans currently offered:

• Free: the browser audit, a one-time "Free Taste Build" of 150,000 tokens (roughly 50 recent conversations), 1 vault, and read-only MCP access.
• Pro: USD 15 per month or USD 144 per year. Includes 3,000,000 tokens per month pooled across your account, up to 3 vaults, MCP access, the browser extension, bring your own storage, and Vault Chat subject to fair use. Pro is a single-user plan: an organization without a Team plan has one seat (its owner).
• Import Pack: USD 29, one-time. Adds 10,000,000 one-off distillation tokens and 1 month of Pro access. One-off tokens do not expire while your account exists.
• Team: USD 60 per month, including 3 seats, or USD 599 per year. Additional seats are available on request at USD 20 per seat per month. Includes 10,000,000 pooled tokens per month (a hard cap), up to 25 vaults, folder-level roles and expiring share links.
• Enterprise & Self-Hosted license: from USD 2,000 per year, or by custom quote. It is governed by a separate order form and license key (see Section 14).

The features of each plan are described on our pricing page at the time you buy. We may add, change or remove features of the Free plan at any time.

5.2 Token quotas

AI processing is measured in tokens. Token quotas are hard caps: before every AI call made with our platform AI keys, we check that your remaining quota covers it. When the quota is used up, AI features that use platform keys stop until your quota resets or you add tokens.

• Unused monthly tokens do not roll over to the next period.
• Monthly quotas reset on your billing-cycle anchor date, which is the date your subscription started.
• AI calls you make with your own provider key (see Section 9) do not count toward your quota.
• "Fair use" for Vault Chat means normal personal or team use. It excludes automated, bulk or resale use. We may rate-limit use that exceeds it.

5.3 Billing, renewal and taxes

Payments are processed by Stripe. Your card details are entered directly with Stripe and never reach our servers.

Subscriptions (Pro and Team) renew automatically at the end of each monthly or annual period at the then-current price, until you cancel. You can cancel at any time in Settings → Billing. Cancellation takes effect at the end of the current paid period, and you keep access until then.

Prices do not include taxes. Value-added tax, goods and services tax or sales tax may be added at checkout where applicable.

5.4 Price changes

We may change prices for future billing periods. We will notify you of a price increase for your subscription at least 30 days before it takes effect. If you do not agree, you can cancel before the increase applies.

5.5 Refunds

Refunds are governed by our Refund Policy. Nothing in these Terms limits any refund or withdrawal right you have under mandatory law.

6. Creator program

We run a creator referral program. Approved creators receive a commission of 25% of the amount paid after discount on qualifying purchases made through their referral, after a 14-day holding period. Their audience receives a 15% discount. If a referred purchase is refunded or charged back, the commission for that purchase is voided. Separate creator terms may apply and prevail over this section for creators.

7. Your content

7.1 You own your content

"Your Content" means everything you or your team members upload, capture, paste, dictate or create in the Service. It also includes the vault files, routing maps and other outputs generated from it. As between you and us, you own Your Content, including your vaults and the outputs created for you.

7.2 The license you give us

You grant us a worldwide, non-exclusive, royalty-free license to host, store, copy, process, transmit and display Your Content. This license covers only what is needed to operate, secure and support the Service for you, as described in our Privacy Policy. It includes sending Your Content to the AI providers and other subprocessors listed there.

This license ends when Your Content is deleted from the Service, except for residual copies in backups. Those are deleted on their normal cycle.

We do not sell Your Content.

7.3 Your responsibility for what you upload

You are responsible for Your Content and for having the right to upload and process it. This matters especially where it contains personal data about other people, such as names, contact details, health information or confidential business information that appears in chats or documents.

Our scrubber automatically redacts certain secrets. In imported sources, quick-start text, voice notes, extension captures and what connected AI tools write, it also redacts email addresses and phone numbers; text you write in the editor, sync from a local folder or ask in Vault Chat is checked for secrets only (see Section 4 of the Privacy Policy). It does not remove names, postal addresses, identification numbers, health data or most other personal data. You must have a lawful basis for processing any third-party personal data you upload. Where the law requires it, you must have informed or obtained the consent of the people concerned.

7.4 Feedback

If you send us suggestions or feedback, we may use them without any obligation to you.

8. AI features and outputs

The Service uses large language models to distill, classify, summarize and answer questions about Your Content. AI output can be inaccurate, incomplete, outdated or inconsistent. It can misattribute facts or merge them incorrectly, including when it resolves conflicts between older and newer information.

You are responsible for reviewing vault files and other outputs before you rely on them, and especially before you use them for legal, medical, financial or other important decisions. Outputs do not represent our views. They are not professional advice.

The Quarantine review lets you approve or reject agent edits to protected files. You are responsible for the changes you approve.

9. Third-party AI providers and services

9.1 Platform AI providers

When you use platform AI features, we send the relevant sanitized text to the AI providers listed in our Privacy Policy. We use their paid API services.

9.2 Bring your own key (BYOK)

You may connect your own AI provider key or endpoint. Calls made with it run on your provider account, under that provider's terms and privacy practices, and you are responsible for any charges. We store your key encrypted and use it only to make the calls you request.

9.3 Third-party tools and sites

The browser extension works on third-party AI chat sites, and the MCP endpoint can be connected to third-party AI tools. Those services are not ours. We do not control them, and your use of them is governed by their own terms. You are responsible for making sure that capturing and injecting context on those sites complies with their terms (see our Acceptable Use Policy).

9.4 Bring your own storage (BYOS)

If you connect a GitHub or git repository, or an S3-compatible bucket, we push your vault to that storage using the credentials you provide. We store those credentials encrypted. The storage provider's terms govern your storage account. We are not responsible for its availability, security or data handling, or for changes made to your vault outside the Service.

10. Security and encryption

We protect Your Content with technical and organizational measures described in our Privacy Policy. These include per-vault AES-256-GCM envelope encryption of vault files at rest and an optional passphrase lock that makes vault files zero-knowledge at rest.

To be clear: on our managed cloud, the Service is not zero-knowledge while a vault is being distilled or served to AI tools, the extension or Vault Chat. Those features need readable, secret-scrubbed text, which is processed in server memory. While a vault is passphrase-locked, those AI, MCP and extension features are paused. If no readable content may ever reach our servers, use a self-hosted deployment.

No system is perfectly secure. We cannot guarantee that unauthorized access will never occur.

11. Beta and preview features

We may offer features labeled beta, preview, early access or similar. They may be incomplete, may change or be withdrawn at any time, and are provided "as is" without any service commitment.

12. Acceptable use

You must follow our Acceptable Use Policy. It forms part of these Terms.

13. Our intellectual property and your license to use the Service

The Service, including its software, engines, design, logos and the Context OS name, is owned by Aqeeli LLC or its licensors and is protected by intellectual property laws. Except for Your Content, we keep all rights in the Service.

Subject to these Terms and your plan, we grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your own personal or internal business purposes.

You must not:

• copy, modify, distribute, sell or rent any part of the Service;
• decompile, reverse engineer or attempt to extract its source code, except where the law expressly permits it despite this restriction;
• use the Service to build a competing product; or
• remove any proprietary notices.

Some components are open-source software licensed under their own terms. Those terms govern those components.

14. Self-hosted and enterprise deployments

Self-hosted licenses are governed by a separate order form, license key and any enterprise agreement ("Enterprise Agreement"). If the Enterprise Agreement conflicts with these Terms, the Enterprise Agreement prevails.

In a self-hosted deployment, you run the software on your own infrastructure. You are the controller (and, where relevant, the processor) of all data in your instance. You are responsible for its hosting, security, backups, AI provider configuration and legal compliance. We do not have access to your instance unless you give it to us.

15. Availability, support and changes to the Service

We aim to keep the Service available and reliable, but we do not guarantee uninterrupted or error-free operation. There is no service level agreement (SLA) unless one is agreed in a signed Enterprise Agreement. We may perform maintenance and may change or discontinue features.

If we discontinue a paid feature that is material to your plan, we will give you reasonable notice. Where appropriate, we will give you a pro-rata refund for any prepaid period you can no longer use.

Support is provided by email at support@contextos.dev.

16. Suspension and termination

By you. You may stop using the Service at any time. You can delete your account in Settings → General. Deleting your account cancels active subscriptions and deletes your personal vaults, files, tokens and purchase records from our database, as described in our Privacy Policy. You can export your vault as Markdown or a ZIP file at any time beforehand.

By us. We may suspend or terminate your access, in whole or in part, if:

• you materially breach these Terms or the Acceptable Use Policy;
• payment fails or a payment is disputed;
• we must do so to comply with law or a lawful request from an authority; or
• your use creates a security, legal or operational risk for us, other users or third parties.

Where reasonable and lawful, we will notify you in advance and give you an opportunity to fix the problem and export your content. We may act immediately in serious cases, such as illegal content, security threats or fraud.

Effect. When your account ends, your license to use the Service ends. We delete Your Content as described in our Privacy Policy. Sections that by their nature should survive will survive termination, including Sections 7.4, 13, 17, 18, 19, 21 and 23.

17. Disclaimers

To the maximum extent permitted by law, the Service and all outputs are provided "as is" and "as available". We disclaim all warranties, whether express, implied or statutory, including warranties of merchantability, fitness for a particular purpose, title, non-infringement and accuracy. We do not warrant that the Service will meet your requirements, that outputs will be accurate, or that the Service will be uninterrupted, secure or free of errors.

Some jurisdictions do not allow certain warranties to be excluded. In those jurisdictions, these exclusions apply only to the extent permitted, and your statutory rights as a consumer are not affected.

18. Limitation of liability

To the maximum extent permitted by law:

• Aqeeli LLC and its members, managers, employees and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages. This includes loss of profits, revenue, data, goodwill or business opportunity, even if we were advised of the possibility.
• Our total liability for all claims arising out of or relating to the Service or these Terms is limited to the total fees you paid us for the Service in the 12 months before the event giving rise to the claim. If you have not paid anything, it is limited to USD 50.

These limits do not apply to liability that cannot be limited or excluded by law. This includes, where applicable, liability for death or personal injury caused by negligence, for fraud, or for gross negligence or willful misconduct. If you are a consumer in the European Union, the United Kingdom or another jurisdiction with mandatory consumer protection rules, these limits apply only as far as those rules allow.

19. Indemnity

If you use the Service for business purposes, you will defend, indemnify and hold harmless Aqeeli LLC and its members, managers and employees against third-party claims, losses, liabilities and costs (including reasonable legal fees) arising from:

• Your Content, including any claim that uploading or processing it infringed someone's rights or violated privacy law;
• your breach of these Terms or the Acceptable Use Policy; or
• your use of third-party services through the Service.

If you are a consumer, this section applies only as far as the law allows.

20. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we will notify you by email or in the app at least 30 days before it takes effect. Changes required by law, or changes for new features, may take effect sooner.

The "Last updated" date shows when the Terms last changed. If you continue to use the Service after a change takes effect, you accept the updated Terms. If you do not agree, you may stop using the Service and delete your account before the change takes effect.

21. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules.

If a dispute arises, please contact us first at legal@contextos.dev. We will try in good faith to resolve it informally within 30 days. If we cannot, the dispute will be decided exclusively by the state or federal courts located in Delaware, and both parties consent to their jurisdiction.

Consumers: if you are a consumer, nothing in this section deprives you of the protection of mandatory laws of your country of residence. This includes the European Union, the United Kingdom and the Kingdom of Saudi Arabia. Nor does it prevent you from bringing proceedings in the courts of your home country where the law gives you that right.

22. Export controls and sanctions

You must comply with all applicable export control and sanctions laws, including those of the United States. You must not use the Service if you are located in, or ordinarily resident in, a country or region subject to comprehensive US sanctions. You must not use it if you are on a US government restricted-party list, or if you act on behalf of anyone who is. You must not use the Service to export or provide technology in violation of those laws.

23. General

• Entire agreement. These Terms, together with the policies they reference and any order form or Enterprise Agreement, are the entire agreement between you and us about the Service.
• Assignment. You may not transfer these Terms without our written consent. We may transfer them in connection with a merger, acquisition, reorganization or sale of assets. If the law requires it, we will notify you.
• Severability. If any provision is found unenforceable, the rest of these Terms stays in effect.
• No waiver. Our failure to enforce a provision is not a waiver of it.
• Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.
• Notices. We may send notices to the email address on your account or show them in the app. You can send notices to legal@contextos.dev.
• Language. We may provide translations of these Terms. If a translation conflicts with the English version, the English version prevails, unless mandatory law requires otherwise.
