What we store
- Your browser may store your preferences (for example units) and, only if you switch it on, your calculation history. You can delete these at any time with “Clear all data”.
- Our hosting provider keeps standard server logs (such as IP address and pages requested) for security, for a limited period.
- If you email us, we use your message only to reply.
This is a template. Have it reviewed by your legal adviser before launch, and update it if you add analytics or advertising.
