You can read the guides and use the tools without accepting optional analytics. Use the button below to review or change your choice.
Necessary preference storage
ttm-consent-v1 is stored in your browser’s local storage to remember your analytics choice for up to 180 days. It contains the choice, its date and the preference version. It does not require an account or contain calculator values. It is used to honor your choice, not to profile your interests.
Optional analytics cookies
Where Google Analytics is enabled and you accept it, Google may set cookies such as _ga and _ga_… to distinguish browser activity and sessions. Analytics is not loaded before consent in our implementation. Rejecting analytics keeps the guides and tools available. On withdrawal we disable Analytics and remove matching first-party Analytics cookies accessible to this website.
Limits of browser controls
You can also clear cookies and local storage through your browser. This may remove your saved choice and cause the preference notice to appear again. External websites opened through source links have their own cookie and privacy policies.
Advertising consent
This site’s analytics preference control is not a Google-certified advertising consent platform. Advertising that requires a certified platform will only be enabled once the relevant configuration is in place. The presence of an ads.txt file or AdSense verification tag does not load an advertising script.
