Privacy Policy

Last updated 14 July 2026
The short version

We don't collect personal data. No accounts, no cookies, no analytics, no tracking scripts. Anything you type into the Address Checker stays in your browser and is never sent to us. If you want the full, honest detail — including the boring bits about web hosting — it's below.

What we don't do

The Address Sanity Checker, specifically

The wallet address and coin/wallet type you enter are processed entirely by JavaScript running in your own browser. They are never transmitted to PlainCrypto, never logged, never stored anywhere by us. Close the tab or refresh the page and it's gone.

The one thing your browser does fetch is a small, publicly-auditable code library (js-sha3) from a third-party code host (cdnjs), used to run the Ethereum checksum maths. That's a code file being downloaded to make the tool work — not your data being sent out. No address or coin information is included in that request.

What does technically exist

To be fully honest rather than just say "we collect nothing" and leave it vague:

If that ever changes

If PlainCrypto ever adds something that does collect data — an email list, a tip jar, a contact form — this page will be updated first, in plain English, explaining exactly what's collected and why, before that feature goes live. We'll only ever collect what's actually needed for the thing you're using.

Your rights

Since we don't currently hold any personal data about you, there's nothing to access, correct, or delete. If that changes in future, standard UK GDPR rights will apply to anything we do collect, and this page will explain how to exercise them.

Questions

If anything here is unclear, get in touch — see the contact details on the Our Promises page.
