Welcome to Premium Electrical Calculators (premiumelectricalcalculators.com). Your privacy is important to us. This Privacy Policy explains how we handle information when you visit our website.
We collect information in the following ways:
a) Information You Provide
If you create an account, we collect your email address, password (stored securely and encrypted by Supabase), and display name. You may also save calculation results to your account, which are stored in our database.
b) Information Collected Automatically
For users with accounts, we automatically log which calculators you visit and when, in order to power the "Recently Used Calculators" feature on your dashboard. This data is tied to your account and is only visible to you.
Google Analytics — We use Google Analytics to understand how visitors use our site. This service may collect information such as your IP address, browser type, pages visited, and time spent on the site. This data is aggregated and anonymous. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
Google AdSense — We use Google AdSense to display advertisements on our site. Google may use cookies and similar technologies to serve ads based on your prior visits to our site or other sites on the internet. You can opt out of personalized advertising by visiting Google's Ads Settings.
c) Calculator Inputs
For users without accounts, all calculator inputs run entirely in your browser and are never transmitted or stored anywhere. For users with accounts, calculation results are only stored if you explicitly click "Save Result" or when a calculation is automatically logged to your history upon reset.
We use the information we collect to:
— Provide and maintain your account
— Display your saved calculations and calculation history on your dashboard
— Show your recently used calculators
— Improve our site through aggregated analytics data
— Serve relevant advertisements through Google AdSense
We do not sell, rent, or share your personal information with third parties for their marketing purposes.
User account data, saved calculations, calculation history, and calculator visit logs are stored securely using Supabase, a third-party database provider. Data is protected using Row Level Security (RLS), meaning each user can only access their own data. Passwords are never stored in plain text.
You have full control over your data. From your dashboard, you can delete any saved calculation or history entry at any time. If you wish to delete your account and all associated data, please contact us at contact@premiumelectricalcalculators.com and we will process your request promptly.
Cookies are small text files stored on your device by your browser. We use localStorage (a browser storage mechanism) to remember your dark mode preference and whether you have accepted our Terms and Conditions. Google Analytics and Google AdSense may also place cookies on your device. You can control or disable cookies through your browser settings.
