Sobre Lokaltools

Ferramentas seguras, rápidas e gratuitas do lado do cliente. Nossas ferramentas locais de arquivos, texto e gráficos processam conteúdo no seu dispositivo com JavaScript, APIs do navegador e WebAssembly quando necessário. Nossos eventos não incluem nomes ou conteúdo de arquivos, texto digitado, valores dos gráficos, erros brutos, emails ou referências de licença. Ferramentas de rede (DNS, WHOIS, IP e testes de velocidade) acessam serviços externos para suas funções. Carregar o site, fontes, bibliotecas e modelos também gera solicitações de rede. WebAssembly por si só não impede acesso à rede.

About the Developer

Lokaltools was built to provide fast, secure, and genuinely private web utilities. Because everything runs locally in your browser using client-side technology, your data never leaves your device.

Lokaltools is proudly developed and maintained by Modern Logic Tech Solutions (mlogictech), an independent software studio specializing in cross-platform applications and web tools.
