Author Fees

Euclid does not charge an article submission fee. Authors may submit manuscripts and participate in the peer-review process without payment.

An Article Processing Charge (APC) of USD 15 applies only to manuscripts that have been officially accepted for publication. The standard length of a published article is 10–12 pages, prepared according to the official Euclid template.

Payment is requested only after the corresponding author receives:

1. an official acceptance notification;

2. an invoice from the Editorial Office; and

3. manual payment instructions sent through the journal’s official email.

Bank account information and other payment details are not displayed publicly for security reasons. Authors must make payments only according to the invoice and instructions received from the official Editorial Office.

After completing the payment, the corresponding author must submit proof of payment by replying to the official payment email. The Editorial Office will verify the payment before the article proceeds to final production and publication.

Payment of the APC does not influence the editorial decision or peer-review process. All manuscripts are evaluated according to their scholarly quality, relevance, originality, and compliance with the journal’s editorial and ethical policies.

Authors should disregard any payment request received before acceptance or sent through an unofficial account or communication channel. If verification is required, please contact the Editorial Office using the contact information published on the Euclid website.
