tacitOS Terms of Service

Effective date: June 30, 2026

These Terms of Service ("Terms") govern your use of the tacitOS desktop

application, tacitOS Cloud, the Google Connector CLI, and related services

(collectively, "tacitOS"). tacitOS is operated by ALB Division Kft. ("tacitOS",

"we", "us", or "our"). By using tacitOS, you agree to these Terms.

1. Your Account

You may need a tacitOS account, Google login, subscription, entitlement, or

device activation to use some features. You are responsible for keeping your

devices, accounts, credentials, and sessions secure. You must provide accurate

information and promptly update it when it changes.

2. Google Login And Google Connector CLI

tacitOS uses two separate Google OAuth surfaces:

• tacitOS app login uses Google identity scopes only to sign you in to tacitOS.
• Google Connector CLI lets you connect Google accounts so your agent can work

with Gmail, Google Drive, Google Calendar, Google Docs, and Google Sheets.

When you connect a Google account to the Google Connector CLI, you authorize

tacitOS and your agent to access and act on that Google account according to the

Google scopes you approve and the commands you run. You represent that you have

the right to connect the account and to permit the requested actions.

You can revoke Google access through your Google Account permissions page and

disconnect or remove local connector state in tacitOS. Google services remain

subject to Google's own terms and policies.

3. Agent Actions And User Responsibility

tacitOS is an AI-agent application. Agent outputs may be incomplete, inaccurate,

or inappropriate for your situation. You are responsible for reviewing agent

plans, outputs, tool calls, messages, files, calendar changes, document edits,

spreadsheet edits, and email actions before relying on them.

Write-capable Google Connector CLI actions can change, create, send, share,

move, trash, or delete content in your Google account. Some write actions require

explicit confirmation in the tool wrapper, but you remain responsible for the

instructions you give, the accounts you connect, and the consequences of actions

performed under your authorization.

tacitOS does not provide legal, financial, medical, tax, or professional advice.

Use professional judgment and obtain qualified advice before relying on agent

outputs in high-risk situations.

4. Acceptable Use

You must not use tacitOS to:

• violate law, contracts, third-party rights, privacy rights, or platform rules;
• send spam, phishing, malware, deceptive messages, or unauthorized bulk email;
• access, copy, modify, delete, or share content without proper authority;
• harass, harm, exploit, or impersonate others;
• bypass security controls, rate limits, entitlement checks, or approval gates;
• reverse engineer hosted services except where law expressly permits it;
• upload malicious code or attempt unauthorized access to systems or data; or
• use connected Google accounts in a way that violates Google terms or policies.

We may suspend or terminate access if we believe your use creates legal,

security, operational, payment, or abuse risk.

5. Subscriptions And Paid Features

Some features require an active subscription, payment, entitlement, or license.

Prices, renewal terms, taxes, refunds, and payment processing may be shown at

checkout or in the product. Payment processing may be handled by Stripe or

another payment provider. Access to paid features may stop if payment fails, a

subscription ends, or entitlement checks cannot be completed.

6. Your Content

You keep ownership of your content. You grant us the limited rights needed to

operate tacitOS, provide requested features, process support requests, secure the

service, and comply with law. This includes the right to process prompts,

attachments, Google Workspace content that you choose to connect, tool results,

and local or cloud metadata as described in the Privacy Policy.

You are responsible for ensuring that you have the rights needed to upload,

process, connect, instruct, edit, send, or share content through tacitOS.

7. Third-Party Services

tacitOS may interoperate with Google, Stripe, model providers, cloud hosting,

email delivery, update hosting, and other third-party services. Third-party

services are governed by their own terms and privacy practices. We are not

responsible for third-party services that we do not control.

If you configure or choose a model provider, you are responsible for deciding

whether that provider is appropriate for the confidentiality and sensitivity of

the data you send to it.

8. Privacy

Our Privacy Policy explains how we collect, use, store, and share information,

including Google user data. By using tacitOS, you agree that we may process

information as described in the Privacy Policy.

9. Software, Updates, And Availability

tacitOS may include desktop software, cloud services, local CLI tools, packaged

tool artifacts, and automatic or manual updates. We may change, suspend, limit,

or discontinue features at any time. We may release beta or experimental

features that are less stable and may change without notice.

You may not remove proprietary notices, misrepresent tacitOS as your own service,

or use tacitOS trademarks or branding without permission.

10. Disclaimers

tacitOS is provided "as is" and "as available" to the maximum extent permitted

by law. We disclaim all warranties, express or implied, including warranties of

merchantability, fitness for a particular purpose, non-infringement, accuracy,

availability, and uninterrupted or error-free operation.

11. Limitation Of Liability

To the maximum extent permitted by law, tacitOS and its operators, affiliates,

employees, contractors, and service providers will not be liable for indirect,

incidental, special, consequential, exemplary, or punitive damages, or for lost

profits, lost revenue, lost data, loss of goodwill, business interruption, or

costs of substitute services.

To the maximum extent permitted by law, our total liability for any claim related

to tacitOS will not exceed the amount you paid to tacitOS for the service during

the three months before the event giving rise to the claim, or EUR 100 if you

used only free features.

Some jurisdictions do not allow certain limitations, so some limitations may not

apply to you.

12. Indemnity

You agree to defend, indemnify, and hold harmless tacitOS and its operators,

affiliates, employees, contractors, and service providers from claims, damages,

losses, liabilities, costs, and expenses arising from your use of tacitOS, your

content, your connected accounts, your instructions to agents, or your violation

of these Terms or applicable law.

13. Termination

You may stop using tacitOS at any time. We may suspend or terminate access if

you violate these Terms, create risk, fail to pay, or if continued service would

be unlawful or impractical. Termination does not affect rights or obligations

that by their nature should survive, including payment obligations, disclaimers,

limitations of liability, and indemnity.

14. Changes To These Terms

We may update these Terms as tacitOS changes. We will update the effective date

when we make material changes. Continued use of tacitOS after updated Terms

become effective means you accept the updated Terms.

15. Governing Law

These Terms are governed by the laws of Hungary, except for conflict-of-law

rules, unless consumer protection law in your country requires otherwise.
