1. Agreement and eligibility
These Terms of Use (“Terms”) govern your use of the Stencra application, stencra.app website, and related services (the “Services”), provided by Prime Root Labs (“we,” “us,” or “our”). By using the Services, you agree to these Terms. Our Privacy Policy explains how we handle information.
You must be legally able to enter into these Terms. If you are below the age of legal majority, you need permission from a parent or legal guardian. Do not use the Services below age 13 or a higher minimum age required by law. Using a design app does not establish eligibility to receive or perform a tattoo.
2. The Stencra service
Stencra provides image-to-stencil conversion, AI-assisted concept generation, artwork refinement, library organization, body-placement mockups, file export, and print preparation. Some features work locally; others require an internet connection, an Apple sign-in, or an eligible subscription.
Features, supported formats, availability, and free or paid allowances can change. AI generation is subject to usage limits, provider availability, and safety restrictions. We do not promise unlimited generation or a specific result. We will provide notice of material changes where required by law.
3. Accounts, backups, and your device
You can use supported local features as a guest. Sign in with Apple enables account features and cloud backup. You are responsible for protecting your device and account access and for keeping an independent copy of important artwork.
Guest data is local and may be lost if you delete the app or its data. Cloud restoration depends on successfully completed synchronization and access to the same account. A pending or failed upload is not a completed backup. We cannot guarantee recovery of unsaved, deleted, or unsynchronized work.
4. Your content and permissions
You retain the rights you already hold in artwork, photographs, prompts, and other material you submit. You grant us a limited, non-exclusive license to process, store, copy, transmit, and display that material as needed to provide, maintain, and secure the features you choose.
You must have the rights and permissions needed to use, upload, adapt, and share your content, including client or body photographs. Do not submit content that infringes copyright, trademarks, privacy, publicity rights, or other rights. Converting a reference into a stencil does not remove another person’s rights in the original.
5. AI output and creative review
AI-generated references may contain errors, unwanted details, inaccurate lettering, or content similar to material created for other users. Review every result before using or sharing it. We do not guarantee originality, exclusivity, copyright protection, or freedom from third-party claims.
As between you and us, we do not claim ownership of your generated output beyond rights required to operate the Services. Any rights you may have depend on applicable law and relevant third-party rights. You remain responsible for checking whether your intended personal or commercial use is permitted.
6. Design tools, not professional tattooing advice
Stencra does not perform tattooing or provide medical advice, hygiene instructions, training, licensing, or a professional assessment of suitability for tattooing. A body preview is a visual approximation; it does not predict healing, skin response, or the final appearance of a tattoo.
A qualified professional must make the relevant artistic and practical decisions. You are responsible for reviewing the design, physical dimensions, orientation, mirroring, print scale, transfer process, and compatibility of your printer and materials. Hardware, ink, paper, and transfer supplies are not included. Never assume a screen preview alone verifies a print’s size or suitability.
7. Acceptable use
You may not use the Services to break the law, infringe rights, exploit or harass people, or create unlawful content. You may not upload malware; attempt unauthorized access; interfere with the Services; bypass security, subscription, or generation limits; or automate requests in a way that overloads the service.
You may not copy, resell, sublicense, or reverse engineer the Stencra software except where applicable law permits it. Do not misrepresent a generated design, mockup, or stencil as a safety certification or professional approval.
8. Subscriptions and purchases
Some features require Stencra Pro or another in-app purchase. Plans, localized prices, billing periods, trials if offered, and renewal terms are shown in the App Store purchase flow before confirmation. Purchases are billed through your Apple Account and subscriptions renew automatically unless canceled under Apple’s applicable rules.
Manage or cancel a subscription in your Apple Account’s Subscriptions settings. Deleting Stencra or deleting your Stencra account does not cancel a subscription. Use Restore Purchases in the app when needed. Refunds and billing disputes are handled under Apple’s policies and applicable consumer law. Statutory rights are not restricted by these Terms.
AI usage limits and availability still apply to paid plans. Purchase screens and the app explain the features and allowances included in the available offering.
9. Third-party services
Stencra uses third-party services for sign-in, cloud backup, subscriptions, AI generation, and website hosting. Their services may have separate terms and periods of unavailability. External links and shared files are subject to the destination’s policies. We are not responsible for third-party content or services except where applicable law makes us responsible.
Your use of the iOS application is also subject to the applicable App Store terms and Apple’s Standard Licensed Application End User License Agreement, unless an applicable custom license is supplied. Apple is not the provider of Stencra’s own support service.
10. Our intellectual property
Stencra’s software, branding, interface, website content, and assets supplied by us belong to us or our licensors. We give you a limited, non-exclusive, non-transferable right to use the Services for their intended purpose, including preparing designs within your own creative workflow. This does not transfer ownership of our software, brand, or other protected materials.
11. Suspension and termination
You may stop using the Services and delete your account at any time. We may restrict or suspend access for material violations, misuse, security threats, legal obligations, or necessary service changes. Where reasonable and legally required, we will provide notice and an opportunity to address the issue.
Terms that should continue by their nature, including ownership, payment obligations already incurred, disclaimers, and limitations of liability, continue after termination.
12. Disclaimers and liability
To the extent permitted by applicable law, the Services are provided “as is” and “as available,” without guarantees of uninterrupted availability, accuracy, fitness for a particular purpose, or non-infringement. We do not warrant that every stencil, AI result, mockup, backup, or print will meet your expectations.
To the extent permitted by law, we are not liable for indirect, incidental, special, or consequential losses, including loss of profits, opportunities, goodwill, or data. Our total liability for claims relating to the Services is limited to the greater of the amount you paid us for the Services in the preceding 12 months or US $50.
These exclusions and limits do not apply where prohibited by law and do not exclude liability that cannot lawfully be excluded, including applicable mandatory consumer rights. Some jurisdictions may not allow part of these limitations.
13. Disputes and changes
These Terms are governed by the laws applicable where Prime Root Labs is established, subject to mandatory protections available in your place of residence. Contact us first if a dispute arises so we can try to resolve it. Nothing here prevents you from using a legal remedy or forum that mandatory law makes available to you.
We may update these Terms as the Services or legal requirements change. We will update the date and provide additional notice or obtain agreement where required. Changes take effect as stated in the notice or updated Terms.
