Also, the above form can also be printed from Coronavirus (pio.gov.cy) The form can be used by anyone 65 and over. Anyone under 65 must use the SMS system.
There are also Q&A on the Government site regarding the measures which hopefully will answer any questions you may have, although on the question of sport/exercise, the position is unclear as the information given does not tie in with the official decree issued by the Minister of Health.
Specifically the decree says that access is only allowed to parks and linear parks and beaches for the purpose of exercise [ie that you cannot go and BBQ, or party or have any sort of gathering at such locations] but the Q&A suggests that you can only exercise in parks, linear parks and on beaches. Clarification has been sought and if there is a response, it will be published on the Tala Blog.
