Feedback privacy
Last updated: October 21, 2026
What is sent
When you submit feedback, we save your message, selected category and tool, optional email address, submission reference and timestamps. Feedback is private, not a public comment. Please do not include passwords, payment details or other sensitive information.
How it is used
The site owner uses feedback to investigate problems, plan improvements and, if you provide an email, contact you about your message. Providing an email is optional and does not subscribe you to marketing.
Storage and access
Feedback is stored in the website's hosted database and is available only through the owner-authorized management interface. We retain it while needed to review and address suggestions, and periodically review whether it is still needed. Hosting providers may process technical request information to operate and protect the service.
Abuse prevention
The server uses a rotating digest of a network address to limit submissions. The feedback database does not store raw IP addresses. Rate-limit entries expire and are cleaned up as new requests arrive.
Your choices
You may leave the email field blank or choose not to submit. To request correction or deletion, send a feedback message identifying the submission reference. We may need to verify the request before acting.
Calculator measurements
Calculator inputs remain in your browser. They are not automatically attached to feedback; only include measurements in your message if you wish to share them.
