Tool inputs and imported results
Score calculations, fraction and angle exercises, Tempo tap measurements, JSON imports and result-code decoding run in your browser. This version does not send those inputs or imported files to our server, require an account, or include a third-party analytics or advertising tag.
Sharing an input through a URL can expose it to anyone with that URL and to normal browser history. Avoid putting personal information in any URL or import you share.
The embedded original is a separate service
Opening the homepage loads an iframe from perceptle.com. Your browser contacts that service directly. The game may use its own storage, cookies, network requests and policies, including when you play or submit a result.
This guide does not read the original site’s cross-origin browser storage. Restrictive browsers may treat embedded storage differently from a direct visit. Opening the game directly can help, but may expose a different saved state.
Website requests and external links
Serving a page involves normal network information such as IP address, browser details and request time. The hosting provider may process request and security logs. External game and source links take you to services with their own policies.
If you email us, your email provider and ours process that message. Include only the information needed to describe the issue. Questions about this guide can be sent to hello@perceptle.net.
