This policy explains what happens to information when you use this website ("we", "us"). Contact: contact@wisercent.com.
All calculations run in your browser. The prices, costs and settings you type in are not sent to our servers. If you use "Save", the data is stored only in your browser's local storage on your device, and you can delete it any time from the Saved calculations list or by clearing site data.
Like most websites, our hosting provider may log technical data such as IP address, browser type and pages visited for security and performance. With your consent we also use Google Analytics 4 (measurement ID G-8W3P621MHT) to measure traffic; it sets its own cookies (such as _ga) to distinguish visitors. If we add advertising services later, they may set cookies to measure traffic or show ads; we will list them here and ask for consent where the law requires. See the Cookie Policy for details and how to opt out.
Fonts are loaded from Google Fonts, which receives your IP address when the page loads. Links to other sites (including TikTok) are governed by their own policies.
Depending on where you live (for example under the GDPR, UK GDPR or CCPA) you may have the right to access, correct or delete personal data we hold, to object to processing, and to complain to your data protection authority. Email contact@wisercent.com to make a request.
This site is not directed at children under 16 and we do not knowingly collect their data.
We may update this policy and will change the date above when we do.
