Privacy Policy - StylePeek

Last updated: March 21, 2026

StylePeek ("the Extension") is a browser extension that lets you inspect fonts, colors, and spacing on any website via a side panel. This privacy policy explains what data is collected and how it is used.

Data Collection

Data Stored Locally

The following data is stored in your browser’s local storage (chrome.storage.local) and never leaves your device:

Inspection results — Typography, color, and spacing data from inspected elements
License state — Whether a Pro license is active (boolean flag)
License key — Your Polar license key (if activated)
Activation ID — Your Polar activation identifier (if activated)

Anonymous Analytics (Google Analytics 4)

The Extension sends anonymous usage events via the GA4 Measurement Protocol:

extension_installed — sent once on first install
extension_updated — sent on extension update
weekly_active — sent once per week to measure active usage

  No personally identifiable information (PII) is included. Events contain only a randomly generated client ID and the event name.

License Validation (Polar)

When a license key is entered, the Extension communicates with the Polar API (api.polar.sh) to:

Validate the license key status
Activate or deactivate the license

Only the license key and organization ID are sent. No browsing data or personal information is transmitted.

Data NOT Collected

The Extension does not collect:

Browsing history or visited URLs
Page content, screenshots, or DOM structure
Personal information (name, email, etc.)
Cookies or tracking identifiers from websites

Web Page Access

The Extension uses the scripting and activeTab APIs to:

Inject an inspection function into the active tab when you click “Start Inspect”
Read computed CSS styles from elements you select

Page content is processed locally and is never transmitted externally. The injection is on-demand only — no persistent content scripts run in the background.

Data Retention

Local storage data persists until you uninstall the Extension or clear browser data
Analytics events are retained according to Google Analytics’ standard retention policy
License data is managed by Polar according to their privacy policy
