Use of the Product

You are responsible for how you use the product, the files or content you import, and any output you create with it. Do not use the product in ways that violate applicable law, platform rules, or third-party rights.

User Content and Local Data

Normal play does not require network access. Optional purchases are handled by Apple StoreKit.

When the product works with local files, local browser sessions, local app data, or local models, you remain responsible for maintaining your own backups and device security.

Downloads, Purchases, and Updates

Downloads, purchases, subscriptions, in-app purchases, refunds, updates, and account-level store records may be handled by the platform linked from the product page, such as Apple App Store, Chrome Web Store, GitHub Releases, or another distribution channel.

Third-Party Services

Some workflows may involve third-party systems selected by you, such as model APIs, app stores, browser accounts, GitHub, or cloud services. Their own terms and policies apply to those services.

Support and Changes

For support, contact zikedece@proton.me or Telegram @hooosberg. These terms may be updated when product features, pricing, distribution, or legal requirements change.
