SmartProxy is a free and open-source browser extension. We care about your privacy as much as you do. We do not collect any data from you. We don't share your data with anyone except for syncing purposes which is disabled by default. All the data usages are listed below. The source-code is available for everyone to read and investigate.
SmartProxy is ad-free meaning that you can't find any ads displayed by SmartProxy. SmartProxy does not modify requests and their contents or responses and their contents. This also means that we do not serve ads by injecting it into pages or by any other means.
SmartProxy allows you to synchronize options across devices by the same browser vendor. Syncing is optional and deabled by default but can be enabled at any time at Settings > General Options > Syncing.
Web Request Monitoring
SmartProxy by default tracks the failed requests for each tab. This can be disabled in Settings > General Options > Error Detection. Error detection will track web requests that have failed to load and summarize them by tab and then domain and display them on extension badge and popup menu. The information is only processed shortly in memory for the sole purpose of this feature. We do not store web browsing activity locally or upload them to a remote server.
Disclaimer; SmartProxy browser extensions has nothing to do with smartproxy.com and its related browser extensions and services. SmartProxy source-code is only hosted in Github and the built, signed and ready to install version is hosted in each browser vendor extensions market store.
