Terms of use

• "Software": the ViraAi application running on your Windows computer, including all updates.
• "Account": your ViraAi account, consisting of a username and password you create on the website, used for both the website and the Software.
• "Plan": the right to use the Software for a model (Veo3, Seedance or Muse AI), a tier (Start, Pro, Unlimit) and a term (1, 6 or 12 months) as published on the Pricing page. A "Combo" is two Plans for two different models bought together.
• "Licence": the right to use the Software bound to your Account and to one computer, arising when a Plan is activated.
• "Third-party Platforms": AI and online services not owned by LoHa Tech that the Software operates using your own accounts, including but not limited to Google (Flow, Veo, Gemini) and ByteDance (Dola, Seedance).
• "Your Resources": platform accounts, sessions, cookies, passwords, proxies and any other means of access that you prepare yourself and load into the Software.
• "Content": prompts, images, videos, audio and all data you enter into or create with the Software.

ViraAi is an automation tool that runs locally on your computer. It performs, on your behalf, actions you could do by hand in a browser with your own accounts: open pages, sign in with your session, enter prompts, click generate, wait for results and download files to your machine; plus local utilities for queues, accounts, proxies and video editing.

You pay for the right to use the Software. You do NOT pay for video generations, platform accounts or any resource of a Third-party Platform. The Software does not create video or images; generation is performed by Third-party Platforms using your account and deducted from that account's quota.

Scope of responsibility — please read this carefully. The Software does one thing: it acts for you. It takes the prompt, reference images and settings YOU entered, submits them to the Third-party Platform (Dola/Seedance, Google Flow/Veo…) using YOUR own account, and returns exactly what that platform replies. Whether the platform accepts the request at all, whether it produces a video, how long it takes and what quality it delivers are decided by that platform’s own algorithms and policies — beyond the control of the Software and of the Company.

The Company’s obligation to you is therefore an obligation of MEANS, not of RESULT: the Company undertakes that the Software performs the operations described and runs correctly on a machine meeting the published requirements; it does not undertake — and genuinely cannot undertake — that a Third-party Platform will produce a video. A platform refusing a prompt is NOT a defect of the Software; on the contrary, the fact that the Software delivered the prompt and returned the refusal verbatim shows it completed its part correctly.

If no video results because the Third-party Platform refuses the content, disallows your reference images, is out of quota, is overloaded, changes its policy or starts charging fees (see section 6), that is an inherent risk of using a third-party service, NOT a defect of the Software, and gives rise to no right of refund (see section 11). The description, tier capacities and machine requirements were available to you before purchase.

LoHa Tech states unequivocally that it does not do, and does not authorise anyone to do in the name of ViraAi, any of the following:

• Sell, give, rent, broker or intermediate accounts of any platform (Google, Dola AI or any other).
• Sell, supply, exchange or distribute cookies, sessions, access tokens, proxies or any other form of access resource.
• Supply video generations, credits or quota of any platform.
• Run courses, training, take students or sell instructional material in any form.
• Advise, instruct or assist in circumventing, bypassing or disabling the rules, limits or technical measures of Third-party Platforms.

Any person or organisation offering the above in the name of ViraAi or LoHa Tech is unrelated to the Company. The Company accepts no responsibility for such transactions and reserves the right to report impersonation to the authorities.

• The Account consists of a username and password you choose; no email is required. You may add a phone/Zalo number for faster support.
• You are responsible for keeping your password confidential and for all activity under your Account. If you suspect it is compromised, change the password or contact support to reset it.
• Because the Account is not tied to an email, password resets are performed by support after verifying you are the account owner (through the channel used to buy the plan or order details). We refuse resets we cannot verify.
• Each Account is used on ONE fixed computer: the machine that first signs in to the Software is bound to the Account for all your Plans. To change machines (new PC, Windows reinstall), contact support to release the old one; we may limit the number of changes to prevent sharing.
• Do not share, lend, rent or resell the Account. Do not create multiple Accounts to circumvent limits or promotions.
• Information you provide must be truthful. The Company may temporarily lock an Account on signs of fraud, sharing, attacks on the system or breach of section 7, and will notify you through the contact channel on file.

When a Plan is activated, LoHa Tech grants you a time-limited, non-exclusive, non-transferable, non-sublicensable right to use the Software on one computer within the capacity of the Plan tier (parallel threads and tier features as published on the Pricing page). You do not acquire ownership of the Software.

• The Software, its source code, interface, the name "ViraAi", logo, documentation and all updates are the intellectual property of LoHa Tech, protected under Vietnamese intellectual property law and international treaties. All rights not expressly granted are reserved.
• Do not reverse-engineer, disassemble, modify, create derivative works of, crack, tamper with or attempt to disable the Software's sign-in, licence check or tier limits; do not use automated tools to extract data from the Service.
• Do not use the Software to provide video generation to third parties by renting out the machine, the account or "running jobs for hire" on the same Licence, unless agreed in writing with the Company.
• Feedback and feature suggestions you send may be used freely by the Company without any obligation.

Breach of this section entitles the Company to revoke the Licence and terminate the Account immediately without refund, and the Company reserves the right to claim damages under the law.

To use the Software you prepare Your Resources yourself. They are created or obtained by you, reside on your computer, are not sent to the Company's servers, and the Company does not receive, store, view or use them.

• You alone control Your Resources and are solely responsible for their origin, the legality of how you obtained them, how you use them and their safekeeping. Loss, leakage or takeover is your risk.
• While using the Software you remain bound by the terms of service of each Third-party Platform. You are responsible for reading, assessing and complying with them. You understand that some platforms may restrict or prohibit automated operation, and you decide, at your own risk, whether to use the Software with those platforms.
• Third-party Platforms may allow, restrict, reduce quota, suspend or disable any account at any time, by their own standards and without notice. That is the platform provider's decision, not something caused by the Software.
• Third-party Platforms may change their interface, flows, prices, quotas or policies at any time, temporarily breaking part of the Software. The Company will try to update within a reasonable time but does not warrant that the Software will remain compatible with every third-party change.
• The Software operates WITHIN each Third-party Platform’s own rules — it performs the same actions a real user would perform by hand, with no added privilege. Those platforms (Dola/Seedance, Google Flow/Veo…) change their policies frequently and often without notice: content accepted yesterday may be refused today. You are responsible for learning and keeping up with the current policies of the platforms you use — that is a condition of using the Software effectively, and the Company cannot do it for you.
• The Company does NOT support, does NOT advise on and STRICTLY PROHIBITS using the Software to break the law, or to circumvent, bypass or defeat any platform’s policies, limits or technical measures (see sections 3 and 7). If you do so deliberately, you bear all consequences — including any restriction or suspension of your account by the platform — and the Company may revoke your Licence under section 7 without refund.
• Some features send your Content directly to a Third-party Platform using your account (for example analysing a video with Gemini to produce a script). Processing on that platform follows the platform's policy and does not pass through the Company's servers.

Cost of generating video on the Dola platform (Seedance model) — read this carefully before buying. At the time the Software was released and on the date this policy starts to apply (the update date shown at the top of this document), the Dola platform (dola.com) — owned and operated by a third party — allows users to generate video with the Seedance model free of charge, within quotas set by Dola itself. That is Dola's own policy at that time and is NOT a commitment, promotion, gift or service of ViraAi or LoHa Tech.

• Dola may, at any time and without notice, change its pricing policy, including but not limited to: starting to charge for video generation; switching to per-generation, credit-based, plan or subscription pricing; raising fees; reducing, narrowing or removing the free quota; limiting the number, length, resolution, quality or speed of videos; restricting the Seedance model (or a particular Seedance version) to paid accounts; applying different terms by region, account type or time; or discontinuing the service altogether.
• If Dola starts charging or changes its policy in any of the ways above, you must learn and comply with Dola's new policies, terms and prices yourself. Any fees Dola charges (plans, credits, taxes, payment fees…) are yours to decide whether to pay and are paid directly to Dola; that is a transaction between you and Dola to which LoHa Tech is not a party, and LoHa Tech does not collect, pay, cover or refund those amounts.
• ViraAi and LoHa Tech do not intervene in, take part in, or negotiate Dola's decisions and have no ability to make Dola keep a free policy. The Company does NOT promise or warrant — expressly or impliedly — that Dola will be free for life, free for any period of time (including throughout the Plan term you have paid for), or keep its current free quota.
• The ViraAi Plan price is a licence fee for using the Software, set independently of any Third-party Platform cost, and does NOT include any cost of generating video on Dola. Whether Dola is free or paid is not a basis for Plan pricing, and a change at Dola does not entitle the Plan to a discount, extension or conversion.
• Dola charging fees does not change what the Software does: it keeps operating on your behalf using your own Dola account. If your account has no paid plan, no credits or no remaining quota, Dola will refuse to generate video — that is Dola's decision, not a defect of the Software (see section 3).
• Any description of generating video on Dola "for free", "at no cost", "without credits", "unlimited" or "as much as you like" — whether on the website, in the Software, documentation, demo videos, social media posts or advice from staff, resellers or referrers — only reflects Dola's policy at that time, is not a commitment by the Company regarding Dola's costs, and does not alter this section.
• The principles in this part apply equally to Google (Flow, Veo, Gemini) and every other Third-party Platform the Software operates.

Dola (or any Third-party Platform) starting to charge, raising fees, reducing or removing its free quota, or allowing video generation only on paid accounts is NOT a defect of the Software, is NOT a breach by the Company, and gives rise to NO right of refund, discount, compensatory extension, Plan change, payment on your behalf or compensation for any Plan you have bought. By paying for a Plan, you confirm that you have read, understood and accepted this risk.

LoHa Tech has no affiliation, agency, authorisation, partnership, sponsorship or endorsement relationship with Google, ByteDance, Dola AI or any platform the Software operates. Their names, marks and logos belong to their respective owners and are mentioned only to describe functionality. The Company does not warrant that your accounts will keep working, does not warrant account recovery, and does not compensate losses arising from Third-party Platform decisions.

You undertake to use the Service only for lawful purposes in compliance with Vietnamese law and the law of your place of residence, in particular the Law on Cybersecurity 2018, the Civil Code 2015 (rights to image, private life, honour and dignity), the Law on Intellectual Property, the Law on Children, the Law on Advertising, the Law on Digital Technology Industry 2025 and their implementing regulations. You must NOT use the Software to create, store, distribute or assist in creating:

• Content against the State of the Socialist Republic of Vietnam, distorting history, undermining national unity, or inciting violence, war, terrorism or hatred based on ethnicity, religion or gender.
• False information or fake news causing public alarm, defaming the reputation of agencies or organisations or the honour and dignity of individuals; impersonating state agencies, organisations, individuals or brands.
• The image, voice or face of real persons (including public figures and relatives) without their consent — including any form of "deepfake" — or content infringing others' private life or personal data.
• Pornographic, obscene or child-abuse content, gambling, superstition, narcotics, weapons, human trafficking and other content prohibited by law.
• Content infringing copyright, trademarks, designs or other intellectual property rights; false advertising; content used for fraud, misappropriation of property or commercial fraud.
• Attacks, vulnerability scanning, malware distribution, overloading or unauthorised interference with the Service, the Company's servers or third parties; unlawful collection of other people's data.

• AI-generated content that is made public must comply with the identification and provenance labelling rules of the Law on Digital Technology Industry 2025 and the rules of each distribution platform. This is your responsibility.
• You are the owner of, and the only person legally responsible for, the Content you create and the way you use and distribute it. The Company does not and cannot moderate Content, because it resides on your machine.
• On lawful request from a competent state authority, the Company will provide information within the scope requested and as required by law.

Breach of this section is a material breach: the Company may terminate the Account and revoke all Licences without refund, and you bear all administrative, civil and criminal liability arising, and indemnify the Company under section 13.

All Content and working data produced while you use the Software belong to you and reside on your computer. The Company does not receive, store, copy, view or use them for any purpose, including product improvement.

• Videos, images and every file the Software downloads are saved directly to a folder on your machine; prompts, history, settings, account and proxy lists live in the application data on your machine.
• Rights in the Content you create belong to you to the extent permitted by the terms of the platform that generated it. You grant the Company no rights in your Content beyond what is needed to run the features you use on your machine.
• Because the data lives on your machine, backups are your responsibility. The Company keeps no copy and cannot restore data when a machine fails, is lost or files are deleted by mistake. You may delete all data at any time by uninstalling the Software and deleting its data folder.
• The personal data that the website and Software do collect (account, orders, device) is described in full in the Personal Data Protection Policy, which forms an integral part of these Terms.

• Plan prices are listed in Vietnamese dong on the Pricing page and in the Software and may change. Price changes do not affect orders you have already created or Plans already paid for during their remaining term. Electronic invoices are issued in accordance with invoicing law; provide your business details when contacting us if you need a company invoice.
• Payment is by bank transfer using a VietQR code to the Company's receiving account, reconciled through the SePay gateway. Each order has its own payment code in the form "VIRA" plus 6 characters, embedded in the QR; manual transfers must carry this exact code in the transfer note.
• When the bank confirms the correct code and full amount, the Plan is activated AUTOMATICALLY (usually within one minute) and appears under Account; the Software picks it up at the next sign-in or refresh. This is digital content whose supply begins immediately after payment at your request.
• UNDERPAYMENT: the Plan is not activated; the system shows the missing amount so you can top up with the same code; once complete, it activates. OVERPAYMENT: the excess is refunded under section 11 or credited to a later purchase by agreement with you.
• WRONG or MISSING code: the system cannot match automatically; contact support with a screenshot of the transfer and we will reconcile and attach it to your order within 3 working days. Transfers to an already-activated or cancelled order are handled as refunds under section 11.
• Plans do NOT auto-renew and no money is charged automatically. Seven days before expiry the Software and the Account page remind you. After expiry without renewal the Software stops accepting new jobs, but every video, image and file on your machine remains intact.

• Renewing the same Plan: the additional days are added to your current expiry; no day is lost.
• Upgrading the tier within a model (Start → Pro → Unlimit) while the old Plan is still active: the remaining value of the old Plan is calculated pro rata by unused days and converted into days of the new Plan, which are added to the new term. The converted figure is shown BEFORE you pay and is fixed when the order is created; late arrival of funds does not change it.
• No downgrade while a Plan is active: the system refuses orders for a lower tier of the same model. You may renew the current Plan or wait for it to expire before buying another.
• A two-model Combo is discounted at the rate published on the Pricing page, for the same term, and only when you have no active Plan on either model; if you have a Plan on one model, buy or renew each model separately.
• Promotions (for example bonus days for longer terms) apply as at the time the order is created and under the published conditions; the Company may change or end promotions without affecting orders already created.

A Plan is digital content supplied and activated immediately after payment at your request; the full description, prices, tier capacities and machine requirements are available before purchase. Accordingly, once a Plan is activated you agree that the right to cancel for change of mind no longer applies. Specifically:

• Orders NOT yet activated (pending or underpaid): you may request cancellation; any amount received is refunded in full to the bank account it came from within 7 working days.
• OVERPAYMENT, DUPLICATE transfers or transfers to an activated/cancelled order: the excess or duplicate is refunded within 7 working days after you provide the receiving account details; bank transfer fees actually charged (if any) are deducted.
• The Software does not run on a machine meeting the published requirements because of a fault attributable to the Company that the Company fails to fix within 7 working days of your report with the necessary information: refund pro rata for the unused days of the current term.
• The Company discontinues the Service for its own reasons: at least 30 days' notice and a pro-rata refund for unused days.

No refund is given where: you change your mind after activation; your Third-party Platform account is restricted, suspended or out of quota; a Third-party Platform (including Dola) starts charging, raises its fees, reduces or removes its free quota, or allows video generation only on paid accounts (see section 6); you do not have or cannot prepare Your Resources; a platform change temporarily disables part of the functionality; your machine does not meet the published requirements; or the Plan is revoked for breach of these Terms. Any refund rights that are mandatory under consumer protection law remain guaranteed.

Nor does the Company refund failures arising on your side, in particular: a prompt you use breaches the content policy of a Third-party Platform and is refused by that platform; a reference image or Your Content you supply is of a kind the Third-party Platform does not allow for video generation; or the result falls short because of your input, your data or the way you use the Software. As stated in sections 3 and 6, the Software does not itself create videos or images — accepting or refusing a prompt is the Third-party Platform's own decision — so these are not faults of the Software and give rise to no right of refund.

All refunds are made to the bank account from which payment was sent to the Company — never in cash and never via intermediaries.

• Technical support via Zalo/phone 0399692275 and email support@lohatech.vn during business hours (Monday to Friday, 8:30–17:30, excluding public holidays); Pro and Unlimit tiers receive priority as published on the Pricing page.
• You receive every Software update released while your Plan is active. Some updates may be mandatory for the Software to keep working with Third-party Platforms.
• The Company warrants that the Software works as described on a machine meeting the published requirements for the duration of your Plan. The warranty excludes faults caused by Third-party Platforms, Your Resources, your machine or network, or your tampering with the Software.
• Supported hardware, operating systems and installation instructions are published on the Download and Details pages; check them before buying.

To the maximum extent permitted by Vietnamese law, the Service is provided "as is" and "as available". The Company does not warrant uninterrupted or error-free operation, does not warrant that output generated by Third-party Platforms reaches any particular quality, quantity or speed, and does not warrant fitness for your particular purpose.

The Company is not liable for the following losses, however arising, except where caused by the Company's wilful misconduct or gross negligence:

• Restriction, quota reduction, suspension or disabling of your account on any Third-party Platform; amounts you paid to that platform, including costs arising when the platform moves from free to paid.
• Loss, leakage or takeover of Your Resources; loss of data or files, damage to your disks or computer.
• Content you create and any legal, financial or reputational consequences of that content or of your use of the Service.
• Loss of revenue, profit, business opportunity or business data, business interruption and any other indirect, incidental, special or consequential loss.
• Interruptions caused by Third-party Platform changes, infrastructure providers (servers, network, payment gateway, banks), force majeure or acts of third parties beyond the Company's reasonable control.

In all cases, the Company's total liability to you in connection with the Service shall not exceed the total amount you actually paid to the Company in the twelve (12) months preceding the event. This cap does not apply to liability that Vietnamese law does not allow to be excluded or limited, in particular consumer rights under the Law on Protection of Consumer Rights 2023, which remain intact.

Indemnity: you agree to indemnify, defend and hold harmless the Company, its managers, employees and partners from all third-party or governmental claims, demands, losses and reasonable costs (including legal fees) arising from: Content you create or distribute; your breach of these Terms or of the law; your breach of Third-party Platform terms; or Your Resources.

• You may stop at any time by uninstalling the Software and requesting Account deletion; fees for the current term are not refunded except as set out in section 11.
• The Company may suspend or terminate the Account and revoke Licences where: you breach section 4, 5 or 7; there are signs of payment fraud, transaction reversal or licence sharing; or a competent state authority so requires. Termination for breach carries no refund.
• The Company may suspend the Service for maintenance, upgrades or incident handling and will give notice where possible. Planned downtime is not a breach by the Company.
• The Company may discontinue a model or the whole Service; section 11 then applies (30 days' notice, pro-rata refund).
• On any termination, the Content and data on your machine remain yours; sections 5, 7, 8, 13, 16 and 17 survive termination.

• The Company may amend these Terms. The update date is always shown at the top; the new version is posted on the website and announced in the Software at least 7 days before it takes effect, except changes required for legal compliance, which take effect immediately.
• The new version applies to orders and terms starting after the effective date. For a term you paid for before the effective date, changes that reduce your rights do not apply until that term ends, unless required by law.
• If you do not agree with the new version, stop buying new terms; buying or renewing after the effective date means you accept it.
• The Company may add, change or remove Software features to keep up with Third-party Platforms, the law or the product roadmap, provided the core capacity of the tier you paid for is not reduced during the remaining term.

• Force majeure: the Company is not liable for failure to perform caused by objective events that could not be foreseen or overcome despite all necessary measures (natural disasters, epidemics, war, government decisions, Internet, power or banking infrastructure failures, or changes made by Third-party Platforms).
• Severability: if any provision is held invalid or unenforceable, the remaining provisions remain in force; the invalid provision is replaced by the lawful provision closest to the original intent.
• Entire agreement: these Terms, together with the Personal Data Protection Policy, the Pricing page and official notices on the website, constitute the entire agreement between you and the Company regarding the Service and supersede all prior communications.
• Assignment: you may not assign your rights or obligations under these Terms without the Company's written consent. The Company may assign them to a successor or to a party acquiring the Service, provided your rights for the paid term are preserved.
• No waiver: the Company's failure to enforce a right at any time is not a waiver of that right.

These Terms are governed by and construed under the laws of Vietnam. In case of dispute, the parties first negotiate in good faith for 30 days from written notice (email or Zalo). Failing that, the dispute is brought before the competent People's Court under Vietnamese law; consumers may choose a dispute-resolution method under the Law on Protection of Consumer Rights.

You may raise complaints about the Service through the channels below; the Company acknowledges and responds within 7 working days.
