Privacy Policy

Information we collect

• Account information, such as email address, profile name, authentication identifiers, and account settings.
• Workflow information submitted to the service, such as files, media references, transcripts, subtitles, generated text, voice previews, exports, and related project metadata.
• Usage, device, and diagnostic information, such as browser type, pages visited, feature events, request identifiers, error logs, and approximate timing or performance data.
• Security signals used to limit free-trial abuse include pseudonymous account and network identifiers derived from account identifiers and IP addresses. The free-credit admission ledger stores hashes rather than raw IP addresses. Infrastructure and security logs may also process IP addresses for their operational purposes.
• Structured editing interaction and derived workflow information, such as proposed cuts, sync offsets, confidence scores, accepted or rejected suggestions, user corrections, timing deltas, style or template choices, retries, exports, and model or engine versions. Vietls is designed to keep this category separate from raw media and text content.
• Billing and entitlement information needed to provide paid access, credits, checkout return handling, subscription state, refunds, and support for payment issues.
• If a user separately joins Vietls Learning or a Data Partnership, the specific samples, rights evidence, consent version, permitted purposes, retention rule, and dataset or model provenance described at enrollment.

How we use information

• To provide, maintain, secure, and improve subtitle extraction, translation, conversion, Shorts preparation, voice, and publishing workflows.
• To authenticate users, maintain sessions, apply plan limits, provision credits, and respond to account or billing support requests.
• To detect abuse, fraud, security incidents, service errors, and operational instability.
• To analyze structured product and editing behavior, evaluate feature quality, and improve automatic sync, cut editing, caption design, personalization, reliability, and workflow recommendations without treating raw customer content as ordinary analytics.
• To provide Private AI Memory inside the user or workspace account when enabled by the user.
• To evaluate or train Vietls models only with data covered by the separate Vietls Learning choice and its recorded rights, consent, and retention terms.
• To use data for a third-party data partnership or licensing program only under a separate, specific authorization or agreement for that purpose.
• To comply with legal obligations and enforce applicable service terms or platform requirements.

User content and generated outputs

Analytics, cookies, and local storage

• Vietls may use cookies, local storage, and similar browser technologies to keep users signed in, remember preferences, protect sessions, and measure product performance.
• To recover interrupted conversions without charging twice, the browser may store a content-derived fingerprint key, an operation identifier, and the requested usage amount for the account and tool. This recovery record does not store source files, subtitle text, or file names. Unresolved records can remain until recovery completes or the user clears browser storage.
• Analytics events are configured to reduce sensitive data collection and avoid sending raw search terms, file contents, or unnecessary personal details where practical.
• Browser settings may allow users to block or delete cookies, but some authentication, security, billing, or tool features may stop working as expected.

Sharing and service providers

• Vietls may share limited information with infrastructure, authentication, storage, analytics, payment, billing, support, and AI processing providers that help operate the service.
• Payment details are handled by payment providers; Vietls receives the transaction, subscription, entitlement, and billing metadata needed to operate paid access.
• Information may be disclosed when required by law, to protect users or the service, to investigate abuse, or as part of a merger, acquisition, financing, or sale of business assets.
• Vietls does not sell or license raw customer content under the standard product service. A separately presented Data Partnership may permit specifically identified data uses only after the required authorization or agreement is recorded.

Retention and deletion

Security and international processing

Your choices and rights

• Users can update certain account profile and contact settings inside the service.
• Users can stop using paid features by cancelling or changing subscriptions according to the billing and purchase policies that apply to the account.
• Depending on location, users may have rights to request access, correction, deletion, portability, objection, or restriction of certain personal information.
• Private AI Memory, Vietls Learning, and Data Partnership choices are separate. Disabling or withdrawing one does not automatically change the others.
• Requests are reviewed according to applicable law, identity verification needs, service security, and legitimate retention requirements.
