Terms of Service

Acceptance of these terms

Service scope

• Vietls provides browser-delivered software for video editing workflows, including subtitle extraction, subtitle editing, translation, text conversion, Shorts preparation, voice previews, project conversion, and related automation.
• The service may include free, trial, paid, beta, experimental, or limited-availability features.
• Features, limits, providers, models, supported formats, and availability may change as the product and infrastructure evolve.

Accounts and security

• You are responsible for keeping your account credentials, sessions, and connected provider accounts secure.
• You must provide accurate account, contact, and billing information when required for the service.
• You are responsible for all activity under your account unless the activity resulted from a security failure that Vietls was legally responsible for preventing.
• Notify Vietls through the support path available in the service if you believe your account has been compromised.

User content and rights

• You keep ownership of content you submit to Vietls, including source media, project files, subtitles, transcripts, scripts, translations, generated metadata, and exported results.
• Under the standard service, you grant Vietls the limited rights needed to host, process, transform, analyze, transmit, display, and store your content to provide, secure, support, and improve the service as described in the Privacy Policy. Raw content remains service-only unless a separate program grants additional rights.
• Vietls may create and use minimized interaction and derived workflow signals for internal product improvement, including proposal, acceptance, rejection, correction, timing, quality, style, performance, and export signals. This standard internal-improvement license does not authorize general reuse of raw media or text as training data.
• Private AI Memory is an account- or workspace-specific personalization feature and is not a model-training or third-party licensing grant.
• If you separately join Vietls Learning, you grant the model-evaluation and model-training rights specifically described at enrollment for the selected samples and purposes. If you separately enter a Data Partnership, that agreement controls the identified licensing or third-party use. These permissions are not bundled together.
• You must have all rights, permissions, and lawful bases needed to upload, process, download, publish, or share content through Vietls.
• Vietls does not review every piece of user content and is not responsible for determining whether your content or outputs comply with third-party rights or platform rules.

Acceptable use

• Do not use Vietls to violate copyright, privacy, publicity, platform, or other rights.
• Do not attempt to bypass rate limits, credit accounting, authentication, security controls, access restrictions, or provider terms.
• Do not upload malware, abuse the service, overload infrastructure, scrape protected areas, reverse engineer non-public systems, or interfere with other users.
• Do not use generated outputs in a way that is unlawful, deceptive, harmful, or misleading.

YouTube and platform downloads

• Downloader and thumbnail tools are intended only for content you own, content you are licensed to process, content the platform expressly permits you to save, or content you are otherwise legally permitted to use.
• Do not use Vietls to bypass paywalls, access controls, copy protections, download restrictions, geographic restrictions, account requirements, or platform rules.
• If a platform, rights holder, or content owner does not allow offline saving, copying, extraction, redistribution, publication, or commercial use, do not use Vietls for that workflow.
• Vietls may block, rate limit, disable, or remove download-related functionality for sources, accounts, or workflows that create copyright, abuse, security, provider, or operational risk.

Paid plans and purchase policies

Third-party services and platforms

Service changes and availability

• Vietls may add, remove, limit, suspend, or modify features to improve the product, manage infrastructure, address security issues, comply with legal requirements, or respond to provider changes.
• The service may be unavailable during maintenance, incidents, provider outages, regional disruptions, or capacity limits.
• Beta, preview, experimental, and diagnostic features may be changed or discontinued with limited notice.

Disclaimers and limitation of liability

Suspension and termination

• You may stop using Vietls at any time, subject to any active billing or cancellation terms that apply to your account.
• Vietls may suspend or terminate access if you violate these terms, create risk for the service or other users, fail to pay amounts owed, or use the service unlawfully.
• After termination, certain provisions will continue where needed, including user responsibility, payment obligations, intellectual property rights, disclaimers, liability limits, and dispute-related terms.
