Optional analytics
Google Analytics 4 is loaded only after an explicit acceptance. It uses first-party cookies such as _ga and _ga_BLNM7XHS7Q, normally configured with a two-year lifetime, to distinguish visits. Consent-dependent data is processed by Google; see the Google Privacy Policy. The site disables Google Signals and advertising personalization. Form contents and calculation input values are excluded.
Your stored choice
The local-storage entry cel-analytics-choice-v1 holds your choice and its timestamp for up to 180 days. It does not contain a name or email. Select Privacy choices at the bottom of the screen to change it. Rejecting after acceptance disables this site’s Analytics measurement and attempts to clear its first-party Analytics cookies. Your browser settings can remove other stored data. Withdrawing consent does not delete data already processed by a provider; contact us for a relevant rights request.
Essential storage and services
WordPress uses authentication and settings cookies for administrators, not an optional public account feature. Hostinger and Cloudflare may use technical security storage when needed for delivery and abuse prevention; provider behavior depends on the active protection and whether a challenge occurs. Short-lived contact and login rate limits operate on the server. The calculators process values locally without uploading media.
Advertising status
AdSense review is being requested. Advertising is disabled while approval and the certified consent setup are pending. The Analytics choice shown by this site is not presented as a Google-certified advertising CMP. Before ads are enabled, the advertising consent platform will describe the actual partners, purposes and regional choices.
