Cookie Policy
Last updated: 2 October 2026
AutoNergy itself sets no HTTP cookies, and its visit statistics are cookieless. There is no advertising or tracking cookie. One cookie can be set by the hosting provider for security, described below. The site also keeps a few preferences in your browser's local storage on your own device; these values are not sent to us. The table lists the keys the site writes.
Security cookie set by the host
| Cookie | Set by | Purpose | Lifetime |
|---|---|---|---|
_vcrcs | Vercel (hosting provider) | Set only when Vercel's bot protection decides to check a visit, for example after many requests in a short time. It records that the browser passed the check so it is not asked again. Strictly necessary for security; it is not used for analytics or advertising. | Short-lived, set by Vercel. |
Local storage
| Key | Type | Purpose | Lifetime |
|---|---|---|---|
autonergy-theme | localStorage | Remembers light or dark mode. | Until cleared. |
autonergy_range_v3 | localStorage | Remembers the year range you last selected on a dashboard. | Until cleared. |
autonergy_news_dismissed | localStorage | Remembers that you closed the newsletter prompt. | Until cleared. |
autonergy_community_v1 | localStorage | Remembers that you closed or used the email sign-up card on a dashboard, so it is not shown again. | Until cleared. |
autonergy_pulse_read | localStorage | Remembers which news roundup items you have opened, so they show as read. | Until cleared. |
You can remove all of these at any time by clearing site data for autonergy.co in your browser settings. The site works without them.
Requests to other providers
Pages load fonts from Google Fonts and some scripts and map files from jsDelivr. Those providers receive your IP address when your browser fetches the files, and this site does not ask them to set cookies. Details are in the Privacy Policy.
