SiteTuner — Privacy Policy
SiteTuner is a Chrome extension that lets you hide elements and change colors, fonts and CSS on websites you choose. It is developed by tanemaki, an independent developer, and is not affiliated with The Browser Company or Arc.
What SiteTuner stores
- Your settings for each site (hostname, color/font/zoom values, CSS selectors of hidden elements, custom CSS). They are saved with
chrome.storage.local on your device only.
What SiteTuner does not do
- It does not collect, transmit, sell or share browsing history, page content or personal data.
- It does not use analytics, tracking or remote code. All code ships inside the extension package.
Permissions
- activeTab / scripting: apply your changes to the tab you are looking at when you open SiteTuner.
- storage: save your per-site settings on your device.
- Optional site access: requested only for a site when you press “Keep on <site>”, so your changes apply on every visit. You can remove it at any time from the extension's “All sites” page or Chrome's extension settings.
Payments (future Pro version)
If a paid Pro version is offered, payment is handled by ExtensionPay and Stripe on their own pages. SiteTuner itself never sees your card details. This page will be updated before any paid feature is released.
