Terms of use

These terms describe the conditions for reading and using Derive.

The agreement covers ordinary reading, linking, form use, downloads, and access from a phone, tablet, or computer. It does not transfer ownership of the site or create a representation that every external resource is suitable for every reader. Where a feature has separate instructions, those instructions form part of these terms only to the extent they do not conflict with mandatory law. If one provision is unenforceable, the remaining provisions continue to operate.

Readers should consider the date and context of each article before applying a suggestion to their own routine. Derive does not receive enough information through a general form to make a personal assessment, and a contributor's experience is not a promise about another person's experience. A reader can pause, modify, or decline a suggestion when it does not fit the setting. Questions requiring individual consideration should be directed to an appropriately qualified local professional.

Content may be corrected, archived, or temporarily withdrawn to address an error, a source update, accessibility work, or maintenance. The original publication date may remain visible so that the history of a page is understandable. Short quotations should retain attribution and enough surrounding context to avoid a misleading impression. Permission requests are assessed using the material, proposed audience, territory, duration, and whether the use is commercial.

Messages are reviewed for relevance and can be removed where they contain another person's private information, abusive language, unlawful material, or a request that the site cannot safely handle. Sending a message does not require a reader to provide confidential records. Derive may retain a limited record of a moderation or rights decision for 24 months so that repeated requests can be handled consistently. That record is not published as a reader profile.

Operational logs may be retained for up to 90 days for security and troubleshooting, while ordinary correspondence may be retained for 24 months after the last exchange. Providers supporting hosting, email delivery, security, or optional grouped measurement may process limited data under their own service agreements. Some providers may operate outside Indonesia, with transfer safeguards considered before use. Questions about these terms can be sent to 120 Cihampelas Street, Bandung, West Java 40131, Indonesia, or +62 22 731 8975; Derive aims to acknowledge a complaint within 10 working days and review it within 30 calendar days. These terms were reviewed on 14 October 2026 and are scheduled for review in October 2027.
