Terms of use

Your account

Beta signup requires an invitation code. Use an email address you control, confirm that address and keep your password private. You are responsible for activity under your account. Password sign-in is required to use the editor.

The free plan

A free account can create one project with up to 10 screens, store 10 MB of project resources and request 10 generated files per day. The daily allowance resets at 00:00 UTC.

Projects in Trash still count until permanently deleted. Stored resources include staged files, copied resources and their licenses. Admitted export jobs count toward the daily allowance even if processing fails.

Free plans will be deleted after 90 days of inactivity. Inactivity means no sign-in to the account for 90 consecutive days. We handle removal manually, so the exact removal time can vary. There is no automatic inactivity-deletion job.

Your content and outputs

You keep ownership of your project content and generated outputs. You permit UI Ninja Inc and its service providers to process and store that content to provide the service. Third-party fonts, images and other resources keep their own license terms.

We do not use your project content to train AI models. UI Ninja Inc retains its software and branding.

Responsible use

Do not access another account’s data without permission, bypass usage limits, send spam or use the service for unlawful activity. Upload only content you have permission to use.

Beta availability

UI Ninja is a beta service. Features, availability and plan limits can change. Review generated specifications and keep the engineering outputs you need before using them in a product.

Privacy and account requests

The privacy notice explains storage, browser caches and service providers. Use the contact form for support, corrections or an account-deletion request. We confirm account ownership and handle these requests manually.
