Contact
I keep one mailbox for this guide so a correction does not depend on a form that can break. If a strongest link on a date page disagrees with chainle.io, that mail is how I hear about it. I then re-fetch the archive row before I change the sentence.
Write to [email protected]. The message reaches the people who publish chainle.xyz. It does not reach the operator of chainle.io, who does not list a contact on that site.
Useful notes include the page URL, the puzzle date, and the sentence you think is wrong, plus the chainle.io screen you compared it with. Privacy requests (access or deletion of the consent record stored in your browser) can use the same address. That record never leaves your browser unless you copy it into the email yourself.
Questions
Is there a phone number?
No. Email is the contact channel.
Can you reset my Chainle score?
No. Scores live in your browser on chainle.io. Clearing that site’s data is done in your browser, not by this guide.
