About
About The Useful Kind
Practical guides, tools, and honest reviews for beauty, health, sun protection, and herbs.
What this website is
The Useful Kind creates practical decision-support tools, source-backed guides and clearly disclosed reviews for everyday choices about skin, body, sun protection and herbs.
How information is prepared
Content should be written clearly, kept proportionate to its purpose and show relevant sources so readers can understand where important guidance comes from.
Limits of health information
The content and tools do not diagnose conditions or replace medical professionals. Individual health needs, medication and personal circumstances may require advice from a doctor, pharmacist or another qualified professional.
Privacy approach
Personal answers should not be stored unless a future feature clearly explains otherwise. When the Sun Protection Advisor is used, coordinates or city-search information are sent directly to Open-Meteo to retrieve location and UV forecast data; planning answers remain in the browser. Privacy-limited product analytics use anonymous identifiers to understand whether people start plans, complete plans or use sharing. The app does not intentionally send precise coordinates, searched city text, recommendation contents, names or email addresses as analytics properties. Analytics are not used for medical profiling, and the analytics provider may attach standard technical web metadata such as browser, page and anonymous session information.
How the Sun Protection Advisor works
The Sun Protection Advisor helps turn forecast UV, selected timing, outdoor duration and activity context into practical general guidance. The detailed calculation approach, sources and limitations live on the Methodology page.
