## Frequently asked questions
### Are these browser extensions free?
Several are completely free with no paywall; the rest have a free tier plus an optional Pro upgrade. Every extension's page states exactly what is free.

### Do these Chrome extensions also work on Microsoft Edge?
Yes. Every extension is built on Manifest V3 and runs on Chrome, Edge and other Chromium browsers from the same build; several also support Firefox. Each product page lists its supported browsers.

### Do the extensions collect or sell my data?
No. Every extension processes your data locally in the browser — no analytics, no telemetry, no third-party SDKs, and nothing is ever sold. Privacy-sensitive features run without the data leaving your device.

### Is this an official store or a third-party directory?
This is our own storefront. We build and support every extension listed here — we are the developer, not a directory reselling other people's add-ons. Updates and support come directly from us.

### How do I install an extension?
Choose where to install. Store listing coming soon. Use the ZIP only when an official store is unavailable. Manual installations do not update automatically. ZIP files are not one-click installers.
