Privacy

Your checker entries are processed in your browser. Ordinary page requests still pass through the hosting provider. Sending a correction, when available, is a separate use of personal information.

The checkers

The battery and charging checkers calculate with the appliances, hours, chemistry, temperatures and battery choices you enter. The checker code does not submit those entries, put them in a URL or save them in browser storage. It fetches the published dataset from this site. Loading the page, scripts, styles and dataset also makes ordinary web requests; that connection information is separate from your checker entries.

Retailer links, analytics and cookies

• Retailer-click counting. Retailer-click counting is currently disabled in this site’s configuration. Retailer links go directly to their destinations. Retailer sites have their own privacy policies.
• Page code. The site’s own scripts contain no analytics tags, pixels or beacons, and do not set cookies or browser storage. The build checks enforce this. This does not establish which hosting analytics or security features are enabled in the Cloudflare account.

Corrections and email

Correction reporting and email contact are not yet available. The operator confirmed on 20 September 2026 that email has not been set up. The correction form is unavailable and no address is presented as a working or monitored contact route.

When reporting is enabled, the intended purpose is to investigate corrections and reply where requested. The form is designed to email the editor, with a prepared-email fallback. It has no separate corrections database, but messages delivered to an editor would be held in a mailbox and may also remain with the sender’s email provider. Mailbox providers, access, retention and deletion arrangements must be confirmed before reporting is enabled. No automatic deletion on resolution is promised.

Hosting

The operator has confirmed that Cloudflare hosts this site. Cloudflare processes connection and traffic information, which can include IP addresses, to provide its services. Its privacy policy describes end-user information and customer logs. The site’s account-level logging, analytics, security settings and retention have not been verified, so this notice does not claim that no connection data is retained or available to the operator.

Details awaiting confirmation

The operator has stated an intention not to retain or sell personal information. That intention does not establish how hosting data or a future mailbox is handled. The following information still needs confirmation:

• An operational contact route for corrections and privacy requests.
• The applicable lawful basis for each use of personal information, and any legitimate interests relied on.
• The hosting features in use, who can access their data, and retention and deletion arrangements.
• Any future email providers and other recipients, mailbox retention and backup deletion arrangements.
• Any international transfers and the applicable safeguards.

This notice remains incomplete until those operational details are confirmed. The ICO’s privacy-information guidance explains the information an operator needs to provide.

Your rights and complaints

Depending on the circumstances and lawful basis, UK data protection law gives you rights to access, correct or erase personal information, restrict its use, object to processing and receive certain information in a portable form. Where processing relies on consent, you can withdraw it. See the ICO’s guidance on your rights.

A working contact route for privacy requests still needs to be set up; the site cannot currently offer an email route for exercising these rights.

You can make a data protection complaint to the Information Commissioner’s Office (ICO).

Assistants

If you use an AI assistant, its provider may retain your prompts and the information you give it under its own policy. This site’s browser tools run the calculation locally; that does not establish how your assistant provider handles the conversation.
