1. Does this browser collect my private data?

Absolutely not. We never send any user privacy to our server or any third-party server with any excuse. This browser is based on Chromium, which uses some Google services(such as keywords suggestion, account synchronization, translation query), but their are options to disable them. In the future, with user's permission we may send Usage statistics and crash reports to our server to help us improve the product's quality.

2. How to revert to an older version?

Firstly, you need to uncheck "Other settings"->"Enable auto update of Cent Browser" to prevent further auto update.

For installed version, you can uninstall the newer version(keep profile untouched) or remove registry item(HKEY_CURRENT_USER\SOFTWARE\CentBrowser), then install the older version.

For portable version, you can extract the newer version to the portable directory and overwrite all files, or delete chrome.exe and rename old_chrome.exe to chrome.exe.

If you get "Profile corrupted" warning on startup, you can delete "Web Data" and "Web Data-journal" under "User Data\Default" and restart the browser.

3. How often do you release updates?

As a small team, we have no strict releasing cycle. But generally we follow these steps:
1. Release beta version, enter an observation period of 0-14 days, fixing bugs iteratively in this period.
2. Release stable version, enter an observation period of 0-7 days, may repackage the installer for minor bugs or release another update for severe bugs.
3. Trigger auto update if no more bugs are reported.

4. How does this browser check for update?

This browser checks update every 6 hours automatically after startup. If you don't want it, you can uncheck "Other settings"->"Enable auto update of Cent Browser" to disable auto update. There is also an "Check for update" command in the main menu(three dot). In rare cases the browser will be updated once if the new installer was downloaded complete and started to run before you unchecked that option.

5. How to close menus and popup dialogs efficiently?

You can press ALT to close menus and ESC to close popup dialogs.

6. What is the meaning of "[NOT RECOMMENDED]" at end of some options?

"[NOT RECOMMENDED]" means there may be side effect of changing this option. For example, changing "Disable HTML5 canvas fingerprinting" may lead some scripts to crash, and changing "Run Flash player in sandbox" may increase the risk of Flash vulnerabilities.

7. Should I check the options in "Memory optimization"?

Unless your RAM is very tight, we don't recommend you to check them. But no performance regression is observed about those options till today.

8. How to disable Flash plugin?

We don't recommend you to do that. If you insist, you can change "Under the hood"->"Privacy"->"Content settings..."->"Flash" to "Block sites from running Flash" and chrome://flags/#run-all-flash-in-allow-mode to "Default".

9. How to recover from black screen deadlock?

Probably fault of hardware acceleration, you can recover by killing GPU process. One of the approaches could be executing the following command in cmd.exe:
wmic process Where "Name='chrome.exe' AND CommandLine Like '%type=gpu-process%'" Call Terminate

10. What is your principles of development for this browser?

We tend to add or strengthen functional and useful features(especially when there are no good extensions). We will try our best to prevent this browser from getting bloated, but we are not chasing for extremely simple. Our final decision would make balance among performance, features and maintenance.
