Cookies & Storage

Effective 13 October 2026 · Sidian Labs

In short

  • We set two cookies, and only to sign you in. No analytics, advertising or tracking cookies.
  • Your preferences (theme, package manager, recently viewed items) stay in your own browser and never reach us.
  • Because everything here is strictly necessary or a preference you set yourself, we don’t need a cookie banner.

This summary helps you read the page; the full text below is what applies.

Cookies

NamePurposeLastsType
lumio_sessionKeeps you signed in. Holds a random token; we store only its hash. HttpOnly and Secure, so scripts can’t read it.30 days, or until you sign outStrictly necessary
lumio_oauthProtects “Continue with Google” sign-in against forgery. Only set while you sign in with Google.10 minutesStrictly necessary

Strictly necessary cookies don’t need consent under the EU ePrivacy rules or the UK PECR, because the service you asked for can’t work without them. If you block them, you can still browse and install free components, but you can’t sign in.

Preferences stored in your browser

The site remembers a few choices in your browser’s local or session storage so pages look the way you left them. This data never leaves your device and is not sent to us.

KeyWhat it remembers
lumi-themeLight or dark theme
lumi-pmYour package manager for install commands (npm, pnpm, bun)
lumi-accent, lumi-finishPreview accent colour and phone finish
comp.recent, scr.recentComponents and screens you viewed recently, for quick return
lumi-meA five-minute copy of your name, email and plan, so the header shows you’re signed in without waiting (cleared when you close the tab)
lumi-providersWhether Google sign-in is available, for this visit
ic.*, comp.cat, comp.qYour current filters and searches on the icon and component pages, for this visit

You can clear all of this at any time from your browser’s site settings. Nothing breaks — the site just forgets your preferences.

Third parties

Fonts and icons are served from our own domain. The live component previews come from our previews site and set no cookies. If you use “Continue with Google”, Google’s own cookies apply on Google’s pages; if you buy a plan, our payment partner’s checkout sets the cookies it needs to process the payment securely, under its own policy.

Changes

If we ever add a cookie that isn’t strictly necessary — for example analytics — we will update this page and ask for your consent first. Contact [email protected] with any questions.
