Yes, we do. As the "one" app and the "one" portal are developed further, new functions will be added, and existing Viseca services will be integrated into "one". It may therefore be necessary to update the terms of use as new user rights and obligations become applicable. If necessary, you will be asked to accept the new terms of use in order to continue using the service, in which case we will notify you in advance on www.viseca.ch and via the other Viseca communication channels.
