Application code is released under MIT. Original documentation and explanatory text are licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). The supplied name and logo are excluded from both grants. This summary is for convenience. The detailed grants and licence terms below control where they differ from the summary. 2. APPLICATION CODE Copyright (c) 2026 Anton Burmistrov, to the extent copyright subsists. The application code authored for shift-happens is released under the MIT License.

The complete MIT License is reproduced in section 8 and included in the HTML.

The original explanatory text, tool description, documentation and original credits text authored for this release are licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). Licence summary: https://creativecommons.org/licenses/by/4.0/ Legal terms: https://creativecommons.org/licenses/by/4.0/legalcode.en You may share and adapt this material for any purpose, including commercially, provided that you give appropriate credit, link to the licence and indicate whether changes were made. Do not imply endorsement or add legal or technical restrictions that prevent others from exercising the licensed rights. Suggested credit: “Based on shift-happens documentation by Anton Burmistrov — antonburmistrov.com — CC BY 4.0.” The CC grant applies to the original text, not to third-party standards or licence texts reproduced or linked here. Those retain their own terms. Creative Commons recommends software-specific licences for software; the application therefore uses MIT rather than CC BY 4.0: https://creativecommons.org/faq/#can-i-apply-a-creative-commons-license-to-software 4. GENERATED ARTWORK AND EXPORTS No attribution is required simply because you used shift-happens. To the extent Anton Burmistrov holds copyright or similar rights in the supplied example shapes or visual elements as incorporated into a user-generated export, Anton Burmistrov grants a worldwide, royalty-free, non-exclusive and perpetual permission to use, reproduce, adapt, publish, distribute, publicly display, license and sell that export for personal or commercial purposes without attribution. This permission covers supplied example elements as incorporated into an export. It does not grant permission to extract or redistribute the tool logo as a standalone asset, use the name for another product, or imply endorsement. shift-happens does not claim ownership of user-created exports. It cannot grant rights in material supplied by somebody else. You are responsible for rights in uploaded SVGs, images, logos, trademarks, identifiable people and any other protected material. A change of shape, colour or format does not remove those rights. Exporting a file does not guarantee that it is independently copyrightable. 5. NAME, LOGO AND PROMOTIONAL ARTWORK The shift-happens name and supplied “s” logo are branding supplied by Anton Burmistrov. They are excluded from the MIT and CC BY 4.0 grants above. They may remain in an unchanged copy of the official release. Use your own name and branding for a differently branded or materially modified derivative tool. No trademark licence, sponsorship or endorsement is granted. This notice is not a trademark availability search. 6. SOFTWARE, ASSETS AND IMPLEMENTATION CREDITS Concept, design direction and supplied logo reference: Anton Burmistrov. Implementation assistance: OpenAI ChatGPT/Codex, under Anton Burmistrov's direction. OpenAI is not represented as an endorser, rights holder or runtime dependency of shift-happens. No third-party runtime library code was identified as bundled in the reviewed self-contained HTML. The release uses native browser APIs for SVG parsing and geometry, Canvas rendering, file handling and media recording. Browser APIs, implementations and codecs are not bundled software and are not relicensed here. The tool includes SVG path parsing, cubic-curve interpolation and subdivision, path matching, easing, dash interpolation, and an uncompressed ZIP writer with CRC-32 checksums. These describe implementation features, not separate packages. No third-party stock imagery or font files are bundled. System font names are fallback requests; the actual fonts belong to the user's operating system and retain their own licences. User-loaded SVGs, images and profiles are not part of this distribution and are not covered by these licensing grants. 7. TECHNICAL REFERENCES AND LOCAL PROCESSING These references document technologies and formats relevant to the tool. They are not bundled libraries and do not imply sponsorship or endorsement.

It contains no analytics, file-upload endpoint, remote runtime library or camera/microphone capture request. Video capture records the rendered canvas. Only the interface theme is persisted in local storage; artwork and editing history remain in memory unless the user exports a file. JSON control profiles do not contain uploaded SVG or image assets. Image layers are decoded and re-encoded as PNG before embedding in exported compositions. The HTML security policy blocks application network connections. Normal page hosting, access logs and any scripts added by the publisher are outside this local-processing statement. Browser support, memory limits and available codecs can affect performance and export availability. 8.
