Privacy & Cookie Policy
At DC Power Planner (dcpowerplanner.com), we take privacy and transparency seriously. We have designed DC Power Planner as a private, client-first electrical design and simulation suite. We do not require account registration, and your system wiring designs remain stored locally on your device.
1. Information We Do NOT Collect
Unlike many web applications, DC Power Planner does not require an account or login. When you use our Visual Designer, Cable Sizing Calculator, or Power Simulator:
- Your wiring schematics, component selections, custom equipment ratings, and canvas positions are stored directly in your browser's
localStorage. - Your diagram files and JSON configurations are never uploaded to our servers or stored in a central database.
- We do not collect names, email addresses, phone numbers, or passwords.
2. Information We Automatically Process
A. Server Logs
Like almost all websites, our hosting provider records standard web server access logs when you request web pages, including your IP address, browser type (user agent), referring URL, and the date and time of the request. These logs are used solely for diagnostic, security, and infrastructure reliability purposes.
B. Local Browser Storage
We use browser localStorage and sessionStorage for strictly functional purposes:
- Saved Designs: Storing your custom wiring diagrams so they are available when you return.
- Disclaimer Acceptance: Recording that you reviewed and agreed to the electrical safety disclaimer.
- Cookie Consent: Remembering your privacy choices (e.g. whether advertising cookies are permitted).
3. Third-Party Advertising & Google AdSense
To keep DC Power Planner 100% free and accessible to all DIYers, caravan owners, marine enthusiasts, and apprentices, we display advertisements provided by third-party advertising networks, primarily Google AdSense.
🛡️ Strict Cookie Consent Enforcement
In accordance with the European General Data Protection Regulation (GDPR), the ePrivacy Directive, and Google's EU User Consent Policy, all third-party advertising cookies, trackers, and Google AdSense scripts are blocked by default until you explicitly choose to accept them. If you reject non-essential cookies, personalized ads and tracking cookies will not be loaded.
When you give consent to advertising cookies:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google's Ads Settings.

5. Affiliate Links & Sponsored Recommendations
Some pages on DC Power Planner may feature links to recommended hardware (such as Victron Energy shunts, Renogy lithium batteries, MPPT controllers, or marine-grade fuses). Some of these links may be affiliate links, meaning we may earn a small referral commission at no additional cost to you if you choose to make a purchase. These recommendations are based on electrical safety, standards compliance, and real-world durability.
