Permissions explained

We request only the permissions we need. The extension never reads your browsing data or page content — here’s what each permission does and why.

Storage

Saves your preferences and sticker data locally on your device so everything loads instantly when you open the extension.

Scripting

Displays the sticker overlay on web pages so you can see and place stickers. Without this, stickers wouldn't appear on sites you visit.

Identity

Enables optional Google sign-in for faster onboarding. Only used if you choose to sign in with Google — email and password works without it.

All HTTPS Sites

Allows stickers to appear on any website you visit. The extension cannot read, access, or collect any page content — it only displays stickers on top of the page.
