Data used by our practice exercises
Completed exercise results are saved in local browser storage so this device can show your practice progress. This is not an online account or a synchronized record. Browser storage can be unavailable or temporary in private browsing.
The score calculator processes the five numbers you enter in the page. Those calculator inputs are not submitted to a server.
This build includes no analytics scripts, advertising scripts, account system or data-collection endpoint for the companion’s exercises. It does not ask for your name, email address or location to play.
The embedded original game
The homepage loads an iframe from perceptle.com. Loading it connects your browser to that separate website. As with other network requests, the service can receive connection information such as your IP address and browser request headers.
In the original public frontend reviewed on October 17, 2026, the game stores completed dated results and a generated player identifier in browser local storage. Its official daily-score submission sends the puzzle date, that identifier and event scores to perceptle.com’s own /api/submit endpoint. The submission response supplies player comparison information for its results display.
Those are original-game behaviors, separate from the practice storage on this site. Browser restrictions on third-party storage can affect what the embedded game remembers. We do not read its cross-origin storage or receive its official score submissions.
The original operator can update its service independently. Consult the original game for its current notices and behavior.
How to remove saved results
Use your browser’s site-data settings to remove this site’s stored data. That clears locally saved practice results. To clear the original game’s saved results or player identifier, remove perceptle.com data as well; clearing only this companion’s data may leave the original’s storage intact.
Clearing data is not reversible here. There is no server copy of our practice progress to restore. Using a different browser or device also starts a separate local history.
Hosting and external links
The published companion is hosted on Cloudflare Pages. Cloudflare processes connection information, including IP addresses and request headers, to deliver pages and assets and protect its network. Our practice exercises do not send their results to a companion server. See Cloudflare’s privacy policy for its handling of service data.
Links marked as original-game links take you to another website. Its controls and data handling apply after you open it.
Changes and questions
If ads, analytics, account features or another collection service are added, this notice must be updated to describe the actual implementation. See Contact for the publication contact status and how to report a privacy-related issue.
