A new quick answers feature that leverages an offline Large Language Model (LLM) to ask basic but highly technical questions and conduct a number of text generation tasks. HTTP proxy client that allows real-time monitoring. Add-ons to create and share web deployables. Phone broadcasting so those web deployables can be shared with anyone on their WiFi network. And much, much more. For $0.99, you have made your MacOS/iOS device one of the most secure, private, and safe devices in the world. Worried about data collection? We do not collect your data. Period. Still worried? Use our content blocker modes instead so you don't have to trust us. All content blocker modes and browsing features use anti-cookie potentiation and ad/tracker blocking technologies. Some of these technologies are more sophisticated than the top names in web security. L;WR - Here's our long(er) explanation: Mobile browsing can be a scary place. Hackers and Cyber Criminals have found innovative ways to target you on the devices and applications you use the most. Cydog Browser is a company which provides the world's leading web security for the masses. This app and safari extension uses multiple methods to accomplish this in order to serve our users. First, we want to help you secure your mobile browser, even though we believe we have a much better one for you to use. Safari is one of the most used mobile browsers in the world. We have developed this extension to secure it with new web standards that don't even exist yet. Second, we believe cyber security is a feedback loop. Without privacy, you can't keep your security over time. We take efforts to limit your web footprint so the data you create and the traces you leave behind don't tell a story to anyone. Lastly, we think the ad tracking ecosystem is detrimental to human behavior because it helps compromise the first two through insidious social loop-holes. Social life is one tactic Hackers and Cyber Criminals use to compromise you. We don't let them because we starve them of data. We hope you enjoy better mobile browser security with the Cydog Toolkit!

You decide who gets in, and you can change your mind at any time. You Decide Who Gets In • Mail from senders you haven't approved goes to Trash, not your Inbox. • Easily grant or revoke access to your inbox. • Auto-delete trash after 30 days—no clutter, no wasted space.

We don't collect your personal data to sell to advertisers.
