What this site does with your data
Most of Reg Check runs in your browser. Your notes, checklist ticks and service history entries are saved in your browser’s local storage under each plate, and you can clear them at any time with “Clear this plate”.
Two features send data to our server. When you type a full number plate, the plate is sent to look up its MOT history from the DVSA MOT History API; results are cached for 24 hours by plate and nothing about you is stored with them. If you upload service history photos or PDFs, the files are passed to Anthropic’s Claude API to read the dates, mileages and garages. We don’t keep the files and the entries read from them are sent back only to you. Anthropic handles them under its commercial terms, which rule out training its models on them.
Your IP address is used to limit how often each feature can be used and is kept for up to two days for that purpose.
