This Copyright Notice explains the copyright documentation and public-use license associated with articles published by IJISTECH (International Journal of Information System and Technology). It reflects the journal's currently displayed Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) notice and the copyright-form requirement contained in the supplied IJISTECH manuscript template.

The IJISTECH manuscript template requires authors to complete and sign an IJISTECH copyright release form before an article may be published. The form is to be submitted to the journal, with the template identifying ijistech@stikomtb.ac.id as the contact email.

The allocation of copyright ownership, permission to publish, and any transfer or retention of rights must be determined from the signed copyright release agreement applicable to the article. This notice alone should not be interpreted as confirming that all authors have transferred copyright to the publisher or that all authors have retained copyright; either claim requires review of the governing form.

The IJISTECH website displays a Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) notice. Where this license applies to a published article, readers may share, copy, redistribute and adapt the licensed material, including for commercial purposes, provided they comply with the license terms.

• Attribution (BY): Give appropriate credit to the author(s), cite the original article, link to the license, and indicate whether changes were made.
• ShareAlike (SA): If an adaptation is publicly shared, distribute the adaptation under the same license or a license permitted as compatible under CC BY-SA 4.0.
• No additional restrictions: Do not impose legal or technological restrictions that prevent others from exercising the freedoms granted by the license.
• Other rights: The license does not automatically grant rights beyond those controlled by the licensor, such as privacy, personality rights, trademarks, or rights in unlicensed third-party content.

When redistributing IJISTECH content to which CC BY-SA 4.0 applies, users should retain the authors' names, article title, journal name, bibliographic information, DOI or permanent article link (when available), original license notice, and a clear indication of modifications, if any. Reusers should consult the full license text for authoritative terms.

Authors are responsible for ensuring that photographs, illustrations, instruments, maps, tables, data or other third-party materials included in their articles may lawfully be published and licensed. When third-party materials are excluded from the article's Creative Commons license, their copyright ownership and permitted use should be clearly identified in the article and relevant permissions obtained. Readers seeking to reuse excluded materials must obtain separate authorization where required.

In line with the journal's published ethical principles, authors must submit original work, acknowledge other sources, disclose relevant conflicts of interest, and avoid duplicate publication, fabrication, falsification and plagiarism. Any correction, retraction, or copyright concern should be directed to the editorial office for review under the journal's applicable policies.

Reuse, sharing and institutional archiving of an article covered by CC BY-SA 4.0 are permitted subject to the license terms. Authors and repositories should reproduce the relevant citation and license notice and ensure that any separate obligations stated in the signed publication agreement are understood. This notice does not create unverified embargo periods or additional restrictions.
