1. Overview & Privacy Commitment
WattsToAh.com ("we", "our", or "the Service") operates a free suite of off-grid electrical, solar, and battery sizing calculators. We respect your privacy and are committed to full transparency regarding data collection, advertising cookies, and analytics.
2. 100% Client-Side Computation Guarantee
Unlike many online utilities, all calculations, appliance wattage inputs, battery chemistry toggles, and wire length entries run entirely within your local web browser's JavaScript engine.
- Your electrical configurations and appliance inventories are never uploaded, saved, or logged on our servers.
- Shareable calculation URLs encode values directly into the browser URL query string (
?watts=...&volts=...) so you can bookmark or share designs privately without database tracking.
3. Google AdSense & Third-Party Advertising Disclosures
We may partner with third-party advertising networks, including Google AdSense, to display contextual advertisements when you visit our website.
Mandatory Google AdSense Policies:
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites across the internet.
- Google's use of advertising cookies enables it and its partners to serve ads to our visitors based on their visits to WattsToAh.com and/or other sites on the Internet.

4. Server Log Files & Edge Infrastructure
WattsToAh.com is delivered via Cloudflare's global edge network. Like almost all web servers, standard non-personally identifiable log files are automatically processed for infrastructure security and performance. These logs may include IP addresses, browser user-agents, referral URLs, and access timestamps strictly for DDoS mitigation, bot management, and edge caching efficiency.
