Privacy policy
This page explains what data BackupPowerCalc collects, the third-party services we use, and the choices you have. We keep it in plain language.
Last updated: June 2026. This policy is provided for transparency and is not legal advice; consult a professional to confirm it meets your obligations.
The short version
Our calculators run entirely in your browser — the appliances and wattages you enter are processed on your device and are not sent to or stored on our server. We do, however, use third-party services for analytics and advertising, and those services set cookies and collect usage data as described below.
Information we collect ourselves
We do not run user accounts, and we do not ask for or store your name, email, or any personal details unless you choose to email us directly. We do not operate a mailing list. Standard server logs at our host may record basic request information (such as IP address and browser type) for security and reliability, as is typical for any website.
Google Analytics
We use Google Analytics (GA4) to understand which pages are visited and how the site is used, so we can improve it. Google Analytics sets cookies and collects information such as the pages you view, your approximate location (derived from IP, which Google truncates), device and browser type, and how you arrived at the site. This data is aggregated and used for statistics; we do not use it to identify you personally. Google's handling of this data is governed by their own policies. You can learn more at Google's Privacy Policy, and you can opt out site-wide using the Google Analytics Opt-out Browser Add-on.
Advertising
This site is supported by advertising. We work with the following ad partners, which may use cookies and similar technologies to serve and measure ads:
- Google AdSense. Google and its partners may use cookies (including the advertising cookie) to serve ads based on your prior visits to this and other websites. You can control personalized advertising through Google Ads Settings. For more on how Google uses data from sites that use its services, see this page.
- Adsterra. We also display ads served by Adsterra, which may set its own cookies and collect usage data to deliver and measure advertising. Its practices are governed by the Adsterra Privacy Policy.
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. You can opt out of personalized advertising from many vendors at aboutads.info/choices or youronlinechoices.eu.
Cookies
The analytics and advertising services described above set cookies in your browser to measure usage and serve ads. You stay in control of these cookies: you can clear or block them at any time through your browser settings, opt out of Google Analytics with the browser add-on linked below, and manage or opt out of personalized advertising through the ad-settings and industry opt-out pages linked above. Blocking cookies will not stop the calculators from working, since they run entirely on your device.
Your choices
- Opt out of Google Analytics with the browser add-on.
- Manage ad personalization through Google Ads Settings and the industry opt-out pages linked above.
- Block or delete cookies in your browser settings.
- Use the calculators without entering any personal information — they require none.
Children
This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy as our tools or partners change. The "last updated" date above reflects the most recent revision.
