Open Source Licenses

Last updated: July 9, 2026

Numio includes or references the third-party resources listed below. Each resource keeps its original license, and brand names and marks belong to their respective owners.

Numio License

Numio itself is proprietary software. Unless a separate written agreement says otherwise, the app source code, product design, documentation, and original assets are not released under an open source license.

High-Resolution Icon Resources

Some bank, payment, and platform icons are based on a high-resolution resource bundle provided via Xiaohongshu by “清澈”. We appreciate 清澈’s help improving Numio's icon resources.

  • Source: high-resolution resources provided via Xiaohongshu by “清澈”.
  • Supplement: bank and securities institution assets not covered by open-source icon libraries use app icons shown on the corresponding brands' official App Store pages.
  • Note: brand names, trademarks, and marks remain the property of their respective owners.

Brand Marks and Trademarks

Some bank, payment, platform, and securities institution avatars use the corresponding brand's official logo or App Store icon. These marks identify the respective institutions; their names, trademarks, and logos remain the property of their respective owners. Numio claims no rights over them and does not imply any affiliation with or endorsement by those institutions.

Custom Card Face Reference Sites

Custom card faces are selected by users. The following sites are third-party references for finding card face images; they are not built-in Numio resources and do not imply any partnership between Numio, the site operators, or the relevant issuers.

  • https://cards.haruka.hk (recommended by Xiaohongshu user “清澈”)
  • https://hi.zzz.moe/face (recommended by Xiaohongshu user “是王同学本人”)
  • Please confirm material permissions, trademark rules, privacy, and security risks before use.

Microsoft Fluent Emoji

Item 3D icons are based on Microsoft Fluent Emoji 3D PNG assets.
