PLAIN-LANGUAGE SUMMARY Ditherfy is free to use for personal and commercial projects. You may use, publish, modify, display, license and sell images and videos that you export from Ditherfy. Ditherfy does not require credit merely because you used the tool to create an export. You remain responsible for having the necessary rights to every image, video, font, graphic mark, audio recording, person, logo or other material that you upload, record or reproduce with the tool. The application source code is released under the MIT License. If you copy, modify or redistribute the code, you must retain the MIT copyright and licence notice reproduced below. The Ditherfy name and supplied logo are not granted under the MIT or Creative Commons licences. Please use different branding for a differently branded or materially modified derivative tool. This summary is provided for convenience. The detailed grants and licence texts 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 Ditherfy is released under the MIT License. This permits use, copying, modification, merging, publication, distribution, sublicensing and sale, including commercial use, provided that the copyright and MIT permission notice are retained in copies or substantial portions. The complete MIT License is reproduced in section 8 of this file. Canonical reference: https://opensource.org/license/mit The MIT grant applies only to material Anton Burmistrov has authority to license.

No endorsement is implied. Suggested documentation credit: “Based on Ditherfy documentation by Anton Burmistrov — antonburmistrov.com — CC BY 4.0.” Creative Commons recommends software-specific licences for software. For that reason, the Ditherfy application code 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 Ditherfy attribution is required simply for using the tool. To the extent Anton Burmistrov holds any copyright or similar right arising solely from Ditherfy-supplied built-in marks or visual elements as incorporated into a user-generated export, Anton Burmistrov grants the user 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 output permission covers Ditherfy-supplied elements only as incorporated into an artwork or media export. It does not grant permission to extract or redistribute the Ditherfy logo as a standalone asset, imply endorsement, or use the Ditherfy name for another product or service. Ditherfy does not claim ownership of user-created exports. However, Ditherfy cannot grant rights in material supplied by somebody else. You are responsible for confirming that your intended use complies with the licences and rights applicable to: - uploaded images, videos and graphic marks; - uploaded or installed fonts; - audio contained in source video or camera recordings; - names, logos, trademarks and brand assets; - identifiable people, privacy, publicity and personality rights; and - any other protected material appearing in an input or export. 5. DITHERFY NAME, LOGO AND PROMOTIONAL ARTWORK The Ditherfy name and supplied logo are branding supplied by Anton Burmistrov. They are excluded from the MIT and CC BY 4.0 grants above. The supplied name and logo may remain in an unchanged copy of the official Ditherfy 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. The social-preview artwork referenced by the application at https://antonburmistrov.com/tool-files/ditherfy/ditherfy-cover.webp is not bundled application code and is excluded from the MIT and CC grants. It may be used to link to or promote the official Ditherfy release, but is not offered as a separately reusable artwork or brand asset. 6. THIRD-PARTY SOFTWARE AND USER-SUPPLIED MATERIAL No third-party runtime library code was identified as bundled in the reviewed self-contained Ditherfy v1.5 HTML release. Ditherfy uses browser-native web platform APIs. Those APIs, browser implementations and codecs are not bundled software and are not relicensed by this notice. Names of system typefaces appearing in Ditherfy are fallback requests only; the corresponding font files are not bundled. A font uploaded by a user remains subject to its own licence. Uploading a font into Ditherfy does not change that font's licence or grant additional rights. Files loaded by users—including images, videos, fonts and custom marks—are not part of the Ditherfy distribution and are not covered by the MIT or CC BY 4.0 grants in this file. 7. TECHNICAL AND IMPLEMENTATION REFERENCES Ditherfy is implemented with standard browser technologies. These references document relevant platform features; they are not bundled dependencies and their inclusion does not imply sponsorship or endorsement.
