Privacy policy


This page explains what data VarAstro processes and how it is handled. We take a simple, conservative approach: we do not sell, rent or otherwise pass your personal data to any third party. Your data is used solely to operate the service and to make astronomical observations available to the community.

Data visible to other users

VarAstro is a collaborative platform for observers of variable stars and exoplanets. By its nature, some information is shared with other members of the system:

  • A registered user has access to the contact e-mail address of other registered users of the system, so that observers can reach one another.
  • When you upload an observation, unless that particular observation is explicitly marked as "private", it is published on the main feed and in the observation database. Together with the observation, the following details are made public for that record: the name of the observer, the description of the observing station, the description of the instrument used and the observation data itself.
  • Observations marked as "private" are not shown on the public feed or in the public observation database.

You remain in control of what you publish: choose the "private" option for any observation you do not wish to share publicly.
