Do Not Sell or Share My Personal Information

Personal information is never sold by girthtodiameter.com, nor shared for cross-context behavioural advertising, which means ads based on what you do across different websites. You won't find ad networks, tracking pixels, or data brokers on this site. The privacy notice lists the little that the site does keep.

How to opt out

You are welcome to record an opt-out at any time. Send an email to [email protected] using "Do not sell or share" as the subject line. No account is required, and opting out doesn't require you to prove your identity.

A browser opt-out signal like Global Privacy Control also counts as a valid request.

After you send it

An emailed request gets recorded, and you'll receive an email confirmation. A Global Privacy Control signal is honoured automatically, with nothing for you to send. Nothing else changes for you, since no selling or sharing happens.

Circumference Tools Ltd, 27 Old Gloucester Street, London WC1N 3AX, United Kingdom, handles every request.
