Proxy Switcher is a browser extension published by Netavi Systems Inc. ("we") under the TechyTools brand. This policy covers the extension on Firefox, Chrome, Edge and other Chromium browsers.


Nothing. The extension has no analytics, no telemetry, no crash reporting, no ads and no tracking of any kind. We do not see your browsing, your proxies or your settings.


Your profiles (proxy servers, ports, user names and passwords, bypass lists, failover servers, auto-switch rules and rule lists), your schedule and your settings are saved in your browser's extension storage (storage.local). They never leave your device unless you export a backup file yourself or turn on sync (see below). Uninstalling the extension deletes them. Proxy passwords are stored the same way your browser stores other extension data; a backup file you export contains them in plain text.

"Just for now" site rules you add from the popup, and the results of proxy tests, are kept in session storage (storage.session) and are deleted when you close the browser.


The extension uses the browser's proxy API to tell the browser which proxy server to use, or to go direct. In Firefox, the browser asks the extension which proxy to use as each request starts; the extension answers from your saved rules, using only the request's address, and does not store or send it anywhere. Your web traffic then goes to the proxy servers you entered, under their operators' own policies. The extension itself does not read the content of web pages, requests or responses, and keeps no record of the sites you visit.


If a proxy asks for a user name and password, the extension hands the browser the ones you saved for that proxy. In Chrome and Edge this needs access to all sites, which the extension asks for only when you save a user name. In Firefox, access to all sites is needed for the proxy choice itself (Firefox only lets an extension choose a proxy for sites it can access), and for SOCKS5 proxies the saved user name and password are given to Firefox together with the proxy. The extension uses this access only to route requests and answer proxy sign-ins, never to read pages.


When you open the popup, the extension reads the address of the tab you are on, to show which proxy that site uses and to let you add a rule for it. The address is not stored unless you add a rule, and is never sent anywhere.


When you press Test this proxy, the extension loads one address through that proxy and shows how long it took and the IP address and location the address reports. The default test address is https://ipinfo.io/json, run by IPinfo under its own privacy policy; you can change it under Privacy & testing. The request goes through the proxy you are testing, so the test service sees that proxy's address, not yours, plus the ordinary information any web request carries. No cookies are sent with it. Nothing is contacted unless you press Test.


If you choose a route for private windows (Incognito in Chrome), the extension applies that route to them. In Firefox this only works if you allow the extension to run in private windows. It does not read or record anything you do there.

If you turn on the WebRTC guard, the browser asks you to allow the extension to change your privacy settings. The extension uses that permission only to set the browser's WebRTC IP handling policy so WebRTC connects through your proxy while a proxy is in use, and to set it back afterwards. It reads no other privacy setting.


When the browser reports that it could not reach your proxy, the extension keeps the last five error messages (the error code and time, no addresses of the pages you visited) to show them in the popup.


If you add a rule list, the extension downloads it from the address you entered, when you add it and about once a day after that. That is an ordinary download from the site you chose; nothing about you or your browsing is sent with it.


If you turn on sync, your profiles (without passwords), rules, schedule, private-window choice and test address are saved in the browser's own sync storage (storage.sync). The browser copies that data between the browsers where you are signed in with sync on, under your Google account (Chrome), Microsoft account (Edge) or Mozilla account (Firefox) and that company's privacy policy. We never receive it. Proxy passwords, which profile is in use, and the WebRTC setting are never synced.


If you buy Pro, the payment is handled by Lemon Squeezy, our merchant of record, under its own privacy policy. When you activate a license in the extension, the extension sends the license key you entered to Lemon Squeezy's license server to confirm it is valid, and re-checks it about once a week. Only the key and an activation id are sent. No browsing data, proxies or settings are ever sent. The extension stores the key, the activation id and its status locally.


We will not sell or transfer this extension or its users to another owner.


If this policy changes, we will update the date above and describe the change in the extension's release notes.
