1. Acceptance of Terms
These Terms of Service ("Terms") are a binding agreement between you and Cai and Vitaldevara Holdings LLC, a California limited liability company that operates Husia ("Husia," "we," "us," or "our"), governing your access to and use of the Husia website, web application, browser extension, and the Gmail and Outlook add-ins (together, the "Service"). By creating an account or using the Service, you agree to these Terms and to our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Service.
You must be at least 18 years old (or the age of majority in your jurisdiction) and able to form a binding contract. If you use the Service on behalf of an organization, you represent that you are authorized to bind it to these Terms.
2. Your Account
You are responsible for the information you provide, for keeping your credentials secure, and for all activity under your account. Notify us promptly at [email protected] of any unauthorized use. You may sign in with email and password or with "Sign in with Google"; you are responsible for the security of whichever method you use.
3. Use License & Reservation of Rights
Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the Service for your own personal or business writing. You may not resell, sublicense, or make the Service available to third parties; copy, modify, or create derivative works of the Service; reverse engineer, decompile, or attempt to extract its source code, prompts, or models; or remove proprietary notices. All rights not expressly granted are reserved by Husia.
4. Your Content & Generated Output
You own your content. You retain all rights to the writing samples, documents, prompts, and other materials you provide ("Your Content"), and to the text the Service generates for you ("Output"). We do not claim ownership of either.
You grant Husia a limited license to host, store, process, and transmit Your Content solely to operate and provide the Service to you — for example, to build your personal writing-style model and generate Output in your voice. We do not use Your Content or Output to train generalized or non-personalized AI/ML models, and we do not sell it. You are responsible for Your Content and for ensuring you have the rights to provide it; do not upload content you are not permitted to use. Because Output is generated from your own materials, you are responsible for how you use it.
5. Acceptable Use
You agree not to use the Service to:
- generate or distribute content that is unlawful, harmful, harassing, defamatory, hateful, sexually exploitative, or that infringes others' intellectual-property or privacy rights;
- impersonate any person or entity, or generate communications intended to deceive, defraud, or mislead (including phishing or social-engineering content);
- send spam, bulk, or unsolicited messages, or otherwise violate anti-spam, email, or marketing laws;
- upload another person's mail, documents, or personal data without authorization;
- reverse engineer, scrape, or extract the underlying models, prompts, or data; circumvent rate limits, quotas, or security controls; or access the Service through automated means except as we expressly permit;
- interfere with or disrupt the Service, or use it to build a competing product.
We may investigate violations and take action, including removing content and suspending or terminating accounts.
6. AI-Generated Output — Accuracy & Your Responsibility
The Service uses AI to produce drafts and suggestions. Output may be inaccurate, incomplete, biased, or inappropriate, and may not reflect your intent. Output is a suggestion, not professional, legal, financial, medical, or other advice. You are solely responsible for reviewing, editing, verifying, and deciding whether to use or send any Output before relying on it.
7. Email Add-ons (Gmail & Outlook)
Husia offers add-ons for Gmail (via Google Workspace) and Outlook (via Microsoft 365) that read a sample of your sent mail to learn your writing voice and draft replies inside your mail client. By connecting a Google or Microsoft account, you additionally agree to the following:
- Authorization. You confirm you are the account holder, or are authorized to connect the account, and that doing so does not violate any policy of your employer or mail provider. Use of the add-ons is also subject to Google's and Microsoft's own terms.
- Drafts, not sending. The add-ons generate draft text only and insert it into your compose window. Husia never sends mail on your behalf. You are solely responsible for reviewing, editing, and choosing to send any draft.
- Read-only access. We request read access to your sent mail (and, for context, the conversation you are replying to) plus the minimum sign-in scopes. We do not request permission to send, modify, or delete your mail. Scopes are detailed in our Privacy Policy (§9 Google, §10 Microsoft).
- Accuracy. AI-generated drafts may be inaccurate, inappropriate, or not reflect your intent. They are suggestions, not advice; you must verify any factual, legal, financial, or other claims before relying on or sending them.
- Disconnecting. You may disconnect an account at any time, which deletes the stored mail content sourced from it as described in the Privacy Policy. You may also revoke access directly from your Google or Microsoft account settings.
Your use of Google user data received through the Gmail add-on adheres to the Google API Services User Data Policy, including the Limited Use requirements.
8. Subscriptions, Billing & Fair Use
Paid plans (Pro and Power User) are billed in advance through Stripe on a monthly or annual cycle and renew automatically until canceled. You can switch plans, change billing intervals, update payment details, or cancel at any time from the billing portal on your account page; cancellation takes effect at the end of the current billing period, and you keep paid access until then. Plan changes mid-cycle are prorated. Except where required by law, payments are non-refundable.
Fair use. Paid plans include generous monthly allowances (e.g. generations and email drafts) intended for genuine individual use. These are soft limits: if sustained usage exceeds your plan's allowance or indicates automated/shared use, we may throttle requests, ask you to move to a higher plan, or — in cases of abuse — suspend the account. Monthly allowances reset each billing month and do not roll over.
Prices and plan allowances may change; we will give existing subscribers reasonable advance notice of any price increase, which takes effect at their next renewal.
9. Refunds
Except where required by law, payments are non-refundable. As a goodwill matter, if you are not satisfied, contact us at [email protected] within 14 days of your first payment for a plan and we will review your request and aim to make it right. Refunds, where granted, apply to the most recent charge only.
10. Intellectual Property
The Service — including its software, models, design, and the "Husia" name and logo — is owned by Husia and protected by law. These Terms grant you no rights in our intellectual property except the limited license in Section 3. If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them to improve the Service, with no obligation to you.
11. Copyright & DMCA Policy
We respect intellectual-property rights and expect users to do the same. If you believe content processed through the Service infringes your copyright, send a notice to [email protected] including: (a) your contact information; (b) identification of the copyrighted work; (c) identification of the allegedly infringing material and where it is located; (d) a statement that you have a good-faith belief the use is not authorized; (e) a statement, under penalty of perjury, that your notice is accurate and you are the owner or authorized to act; and (f) your physical or electronic signature. We respond to valid notices, may remove infringing content, and terminate the accounts of repeat infringers. If you believe content was removed in error, you may submit a counter-notice to the same address.
12. Third-Party Services
The Service relies on third parties, including Stripe (payments), Google and Microsoft (the email add-ins and sign-in), and OpenAI and Anthropic (AI generation). Your use of features involving these providers is also subject to their terms, and we are not responsible for third-party services. Where you connect a Google or Microsoft account, the additional terms in Section 7 and our Privacy Policy apply.
13. Disclaimer of Warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT OUTPUT WILL BE ACCURATE OR RELIABLE. Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you.
14. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, HUSIA AND ITS OFFICERS, EMPLOYEES, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS, ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD $100. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
15. Indemnification
You agree to indemnify and hold harmless Husia from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of Your Content, your use of the Service, or your violation of these Terms or of any law or third-party right.
16. Termination
You may stop using the Service and delete your account at any time from your account page. We may suspend or terminate your access if you breach these Terms, if required by law, or to protect the Service or other users. On termination, your license ends; provisions that by their nature should survive (including Sections 4, 10, 13, 14, 15, and 18) survive. Deletion of your data on termination is handled as described in the Privacy Policy.
17. Governing Law
These Terms are governed by the laws of the State of California, United States, without regard to its conflict-of-laws rules, and the U.N. Convention on Contracts for the International Sale of Goods does not apply. Subject to Section 18, the state and federal courts located in California will have exclusive jurisdiction.
18. Dispute Resolution; Arbitration; Class-Action Waiver
Please read this section carefully — it affects your legal rights.
Informal resolution first. Before filing any claim, you agree to contact us at [email protected] and attempt to resolve the dispute informally for at least 30 days.
Binding arbitration. Except for claims that qualify for small-claims court and claims for injunctive relief regarding intellectual property, any dispute arising out of or relating to these Terms or the Service that is not resolved informally will be settled by final and binding individual arbitration administered by the American Arbitration Association (AAA) under its applicable Consumer Arbitration Rules, seated in California, rather than in court.
Class-action waiver. You and Husia agree to bring claims only in an individual capacity, and not as a plaintiff or class member in any class, collective, or representative proceeding.
Opt-out. You may opt out of this arbitration agreement within 30 days of first accepting these Terms by emailing [email protected] with your account email and a statement that you opt out. Nothing here prevents either party from seeking relief in small-claims court for qualifying claims.
19. Changes to These Terms
We may update these Terms from time to time. For material changes we will provide reasonable notice (for example, by posting the updated Terms with a new "Last updated" date or by email). Your continued use of the Service after changes take effect constitutes acceptance.
20. General
These Terms and the Privacy Policy are the entire agreement between you and Husia regarding the Service. If any provision is held unenforceable, the rest remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Nothing here creates a partnership, agency, or employment relationship.
