1. Status of this document
This is a translation of a Japanese draft for release preparation, not operative contract terms. Legal and native-speaker reviews are pending. Acceptance is not required for local use; viewing the draft or using the app locally is not recorded as consent or a contract. Do not use this for public release until outstanding decisions are resolved and final terms are issued. Every proposal below remains unadopted.
2. Features currently provided
[Current] The Windows development build provides and tests sample display, manual direction/eyes/mouth checks, PC camera input, video output for OBS and existing project saving. Sensitivity, expression quality and real-face use alongside OBS in the current candidate still need adjustment and verification. [Policy] Purchasing is not a prerequisite for downloading the app. Public distribution is being prepared; this does not establish free access to every feature, free generation allowances or paid entitlements. Image generation, public cloud preprocessing, live authentication and payments are not offered. Moving heavy image preparation to the cloud does not move streaming-time rendering, camera processing or OBS off the PC. Low-end performance and continued processing after PC shutdown are not guaranteed.
3. Software rights and creative work are separate
PROPOSAL: Grant a non-exclusive licence to use the software, without transferring ownership or source-code rights. Device limits, organisational use and execution after a contract ends remain undecided. Third-party software follows its own licences. Rights in imported work remain with their existing holders; storing it does not transfer those rights to the operator. Final terms for generated characters will be separate from the software licence.
4. Streaming, videos, merchandise and business use
PROPOSAL: Permit monetised streams, published videos, merchandise and business use of characters for which the user holds the necessary rights. This is not a confirmed grant and cannot override third-party material rights or future AI-provider terms. Permission to distribute source assets or sell models, attribution, commissioned work, customer delivery and business seat limits require separate decisions. This draft does not restrict rights the user already holds.
5. Imported images and appropriate use
[Proposed clause] Users must establish a lawful basis for imported images, text and likenesses, including authorship, rightsholder permission or an applicable license, and secure the rights needed for intended copying, uploading, editing, processing by cloud providers, streaming and commercial use. Buying an image may not grant all these permissions. Use that infringes others' rights without authorization is prohibited. Users are responsible for their violations under applicable law; this does not transfer all of the operator's own legal responsibilities to users. Original asset rights stay with the existing rightsholders and are not transferred to the operator by saving or processing them.
6. Redistribution, resale and account sharing
[Proposed clause] Unless separately authorized, prohibited conduct includes unauthorized copying, redistribution or sale of proprietary code owned by the operator, restricted or non-public model assets, the application or bundled materials; use of another person's credentials; improper bypassing of authentication or usage controls; and decompilation, disassembly or reverse engineering outside permitted limits. Activities allowed by applicable law, required statutory backup rights and rights under third-party OSS licenses remain unaffected. RIFE, ToonOut and other dependency code and models have their own licenses; this clause does not override their rights or notice requirements. It does not prohibit users' lawful use or backup of original assets they own. Disconnected services do not establish seat limits or paid entitlements.
7. AI output and quality
[Current] Text-to-image generation and AI conversation are not offered. Cloud image preparation is being prepared for connection. [Proposed clause] We do not uniformly guarantee originality, non-similarity to others' works, copyright protection in every region or a desired appearance for AI-processed outputs. Users should be able to review outputs before publication. Terms will distinguish technical processing failures from preference-based recreation. Statutory conformity and remedies remain unaffected; prices, retries and refund conditions will be settled before formal availability.
8. Storage, history and export
CURRENT: Work is automatically saved on the device and can be exported as an .aster file. Adding a candidate does not change an adopted image. Changing the adopted front marks direction images and other dependent data based on the previous front as needing an update. Earlier candidates and assets are retained; automatic deletion is not implemented. Keep exported backups elsewhere against device failure or insufficient storage. See the privacy draft for details.
9. Future contracts, renewal and cancellation
CURRENT: There is no billing contract, automatic renewal or contract verification. PROPOSAL: Before introducing paid functions, disclose prices, renewal intervals, generation allowances, cancellation steps, effective dates and renewal notices. Failed-payment notices, grace periods, restrictions, restoration and software use after cancellation remain undecided. Distinguish rights in acquired work from access to software or cloud features, and provide an opportunity to export. Decide the software automatic-update policy separately.
10. Support, changes, closure and liability
PROPOSAL: Publish supported systems, requirements, support contacts, languages and support periods; investigate reproducible faults and explain workarounds. Distinguish creative preferences and compatibility with every third-party configuration from supported specifications. Give advance information on material changes or closure and on exporting data; notice periods remain undecided. Set liability scope and any limits after legal review, without excluding liabilities that cannot lawfully be excluded, including applicable cases of intent or gross negligence and mandatory consumer rights.
11. The sample character Aster
CONFIRMED INTENTION: Include Aster as a free sample in the future full release. CURRENT: Only review materials are bundled; completed tracking or interpolation is not promised. This draft alone does not authorise public redistribution or commercial use of the assets. PROPOSAL: Permit monetised streaming and videos using the sample, while separately restricting redistribution or resale of the assets or model itself. Merchandise, business use, modification, attribution and trademark use still need decisions.
12. International use and final terms
PROPOSAL: Check consumer, privacy and AI-related requirements in each sales territory. Governing law, jurisdiction and controlling language remain undecided; no term should deprive consumers of mandatory rights in their country of residence. Legal equivalence between the Japanese source and translations is unverified. When consent to final documents is needed, identify and record the document ID, version, language, acceptance time and scope. Do not infer acceptance from viewing a draft.
13. App-specific formats and video use
[Current] Models, rendering data and .aster projects use an app-specific format. Direct import into other VTuber software and conversion to VRM or Live2D are unsupported. Video display through OBS is an intended use, but does not establish model compatibility. Technical compatibility, software licensing and rights to videos or works are separate. The format alone does not restrict existing rights or other lawful uses of users' original assets.
14. Reports and protection of rights
[Proposed clause] Reports of infringement or misuse may be sent to the official email listed on the site. We will seek relevant details such as the material, basis of rights and contact information. Considering evidence, safety, urgency and an opportunity for the affected party to explain, we intend to consider necessary and proportionate restrictions on the relevant use or processing and provide reasons and a way to contact us. Where appropriate and permitted by law, measures may include suspension, injunctive relief and claims for damages. A report alone does not automatically establish infringement or a large penalty, and litigation is not promised in every case. This is not a complete exclusion of the operator's liability; non-excludable liability and mandatory consumer rights, including those abroad, remain protected. Reporting, objection procedures, decision criteria and response periods require legal review before formal service.
