Your plan stays in your browser.

Calculations run in your browser. We use Cloudflare Web Analytics for page-visit and page-performance statistics.

Calculations and saved settings

The calculator runs in your web browser. It stores your latest valid equipment settings and trip dates in this browser's local storage under weekend-power-plan-v1. The calculator does not submit these form values to a server. Clear this site's browser storage to remove the saved plan. Reset example replaces it with the example values.

Share links

Share plan creates a link containing your entered trip and equipment values after the # character. That fragment is read by the recipient's browser and is not included in the HTTP request to the host. It is not encrypted: anyone who receives the full link can read the values. Share it only with people you intend to receive the plan.

Older local versions used a ?plan= query parameter. This version can still read those links, but a query parameter is included in the request to the host. New links use a fragment instead.

Hosting and ordinary web requests

When this site is hosted, its provider receives ordinary web-request information, such as your IP address, the requested page and browser headers, to deliver and protect the site. That is separate from the browser-only calculation. The calculator itself has no server-side database for your plans.

This site is hosted on Cloudflare Pages. See Cloudflare's privacy policy for the provider's processing. This page describes the actual site code; it is not a statement that the hosting provider keeps no logs.

Visitor statistics

We use Cloudflare Web Analytics to measure page visits and page performance. Your browser loads Cloudflare's analytics script and sends measurements to Cloudflare. These include the page path, referring website and browser/device and page-load information. We do not send your equipment settings or trip dates as analytics events, and page addresses in the measurements exclude query strings and fragments.

Cloudflare Web Analytics does not use tracking cookies or browser local storage for these statistics. Saving your plan is separate: the calculator uses local storage as described above. Some browser settings or blockers can prevent measurements, so these statistics are not an exact count of every visitor.

See Cloudflare Web Analytics documentation and Cloudflare's privacy policy. This site loads no advertising network or merchant affiliate-tracking script. Merely viewing it does not contact Jackery or Affiliatly.

Affiliate links and external sites

The calculator and guide contain a clearly marked affiliate link to Jackery's US store. If you follow it and make a qualifying purchase, we may earn a commission. The link includes our public referral identifier and campaign parameters; we do not add your plan or equipment inputs to it. This is an ordinary outbound link, not an embedded tracking pixel.

After you open the merchant link, Jackery and its affiliate provider may process referral information and set cookies according to their own policies and your choices. Availability and attribution can depend on the merchant's terms and consent settings. See Jackery's privacy policy and Affiliatly's privacy policy.

Other manufacturer information and hosting-policy links also take you to external sites with their own practices.
