Your work stays on your machine
The short version: the extension does not track you, does not phone home, and stores everything locally. There is nothing for us to collect because we never collect it.

No telemetry, no analytics
Pixel Perfect Advanced ships with no analytics SDK, no usage tracking and no crash reporting that leaves your browser. We do not measure which sites you compare, which layers you load, or how often you use it.
Everything is local
Your overlay layers, their opacity, blend mode and position, and your per-site setup are saved in your browser's own storage on your device. They are not uploaded to a server and they are not shared with us or anyone else.
- No account and no sign-in.
- No network requests to our servers from the extension.
- No selling or sharing of data, because there is no data leaving your browser to sell.
Images you overlay
When you add a design as a layer, that image is held in local storage for your convenience and rendered on the page in front of you. It is never transmitted to us.
If your browser profile has sync turned on, your browser, not this extension, may move local extension storage between your own devices. That is your browser's feature and stays within your account.
