How votes are stored
Voting is anonymous: no account and no free text. To stop repeat votes we store a pseudonymised identifier with each vote, a one-way SHA-256 hash of your IP address, your browser details and a secret key plus the current date, so the identifier changes every day. Your IP address itself is not stored. The hash still counts as pseudonymised personal data under UK GDPR. Our lawful basis is legitimate interests: keeping the votes honest and the results useful.
Votes and their hashes are deleted after 90 days. The hash is never sent to Google Analytics; the analytics event for a vote carries only the district and the rating. ND Media Ltd (company 10784524) operates NoiseCheck.uk and is the data controller. To ask about your data or object to this use, email [email protected]. You can also complain to the ICO.
