About

icoso consulting SL is an owner-managed software and consulting company based in Santander, Spain, founded in 2024 by Daniel Osorio Fernandez. The company advises firms in regulated industries on test, project and requirements management and develops its own software.

Its main product is Iséou (formerly Luna), a cycle app for iPhone and Android in 24 languages. Iséou covers the menstrual cycle, pregnancy, breastfeeding, perimenopause and menopause, and fertility treatment such as IVF in one app, so users keep their history when their life phase changes. Health entries are encrypted on the device with AES-256 before they are synced, the servers are located in the EU, and the service is operated under the GDPR. Iséou shows no ads and does not sell data; it is funded by subscriptions and one-time passes. Every privacy claim is listed with its source at https://iseou.app/facts/.

Iséou is not a medical device. It documents and reminds; it does not diagnose or give treatment recommendations.
