Acceptable Use Policy
Last updated: November 14, 2026
This Acceptable Use Policy ("Policy") applies to all images you upload to LineStencil and all stencils generated through it. LineStencil is operated by Shanghai Jushen Intelligence Technology Co., Ltd. ("we", "us"). By using LineStencil you agree to this Policy. It is part of our Terms of Service.
1. Scope
This Policy covers images you upload (inputs) and AI-generated stencils (outputs). LineStencil does not accept free-text prompts; the instructions sent to the AI model are fixed by us.
2. Prohibited content
You may not upload, or use LineStencil to generate, any of the following six categories:
- Pornography / NSFW: nudity or sexual content.
- Violence / gore: graphic real injuries, mutilation or real dead bodies. (Skulls, horror and fantasy art are fine.)
- Hate speech: hate symbols, extremist imagery, or content attacking people for who they are.
- Child-unsafe content (CSAM): any sexual or sexualized content involving minors. Zero tolerance; we report it to the authorities.
- Deepfakes / impersonation: putting one person's face on another, nudifying, placing real people in fabricated intimate scenes, or making a real person appear to say or do something they did not, whether or not they consent. LineStencil has no such features and you may not try to use it this way.
- Copyright / trademark infringement: images you don't have the right to use, including other artists' work, famous brand logos and copyrighted characters.
2.1 Source of uploaded material
You may only upload your own photos and artwork, or material for which you have explicit permission from the people shown and the rights holder. Uploading another person's photo without their consent is prohibited. Before each upload you must confirm that the image is yours or that you have permission. Permission does not make the deepfake uses in section 2(5) acceptable.
2.2 Other prohibited conduct
- Trying to get around our safety checks, free limits or security measures, or automating requests.
- Passing AI-generated stencils off as hand-drawn work in a way that misleads clients.
- Reselling access to LineStencil without our written permission.
3. Content moderation
- Before generation: every uploaded image is screened automatically by Google Gemini 3.5 Flash Lite. Sexual content, content involving minors, graphic gore and hate symbols are blocked and no stencil is made. Possible celebrity likenesses and brand logos are flagged in our logs for review.
- After generation, before display: every generated stencil is screened again before it is shown.
- Model safety filters: the generation model (Google Gemini 3.1 Flash Image) applies Google's own safety filters as well.
- Logs and human review: we keep a log of every safety decision (the result and category only; we do not store your images) and review flagged cases and user reports by hand. We update our screening rules as new abuse patterns appear.
- There is no public gallery; stencils are only shown to the person who made them.
4. Reporting
If you see a stencil or behavior that breaks this Policy, or believe LineStencil was used to infringe your rights, email [email protected] with the subject "Report". Include what happened and, if you can, the image. Reports are confidential, reviewed by a person, and malicious false reports are themselves a violation.
| Severity | Examples | First response | Resolution |
|---|---|---|---|
| Critical | Child safety, terrorism | Within 24 hours | Within 3 days |
| High | Deepfakes, sexual content, hate | Within 2 business days | Within 5 business days |
| Other | Copyright, misuse | Within 5 business days | Within 15 business days |
5. Enforcement
- Blocking the image or stencil (automatic).
- Warning by email.
- Reducing or removing free and paid usage, including forfeiting unused stencils for serious or repeated violations.
- Suspending or permanently closing the account, and blocking access from the device or network.
- Reporting child sexual abuse material and other illegal content to the relevant authorities.
6. Appeals
If you think an image was blocked or your account was restricted by mistake, email [email protected] with the subject "Appeal" within 30 days. A person who did not make the original decision will review it within 10 business days.
7. Changes
We may update this Policy. Material changes will be announced on this page at least 14 days before they take effect, and by email to account holders.
