About

Casulo

O Casulo ajuda você a controlar o tempo de tela com base em onde você está e em que horas. Escolha os apps que quer pausar e defina zonas, como casa, trabalho ou escola, e horários. Fora das zonas ou dentro dos horários definidos, os apps escolhidos ficam pausados. Ao voltar, eles ficam disponíveis de novo, sem você precisar fazer nada. IDEAL PARA • Reduzir distrações no trabalho e nos estudos • Manter o foco fora de casa • Organizar a rotina de tempo de tela da família • Criar momentos sem celular, como refeições e hora de dormir PRINCIPAIS RECURSOS • Zonas: defina locais e o que acontece ao entrar e sair de cada um • Horários: programe pausas diárias ou semanais • Pausa rápida: libere um app por alguns minutos quando precisar • Apple Watch: veja e controle as pausas pelo pulso • Chave em outro aparelho: libere as pausas a partir de um segundo iPhone COMO FUNCIONA O Casulo usa os recursos de Tempo de Uso do iOS. A seleção de apps é feita pelo seletor do próprio sistema, e o Casulo nunca sabe quais apps você escolheu. Enquanto um app está pausado, ele não pode ser aberto até a pausa terminar ou você liberá-lo. PRIVACIDADE O Casulo não acessa o conteúdo, as contas ou os dados de nenhum outro app. A localização é usada apenas para saber se você está dentro ou fora de uma zona. Termos de Uso: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Política de Privacidade: http://casulo4.hospedagemdesites.ws/privacidade.html
