Cookie has two faults that seriously detract from its credibility (and I apologize to all for not having exposed them long ago):
1. COOKIE DISABLES HSTS (AN INTERNET SECURITY FEATURE) BY DEFAULT any time it clears cache, it doesn't advise you that a security feature has been disabled, and it doesn't give you an option to change the default behavior.
(Cookie's developer) Russell's response to my objections to his having unilaterally and with finality disabled a security feature was "if no one [other than you] wants this option, it’s not worth my effort."
And THAT is as stupidly dangerous and bizarrely arrogant an approach to security as I can imagine.
Security is NOT a toy for developers to play with, and no RESPECTABLE developer would disable a security feature with neither an up-front warning nor a means to re-enable it!
2. Cookie offers timer options to clear Safari's cache and history while it's running despite the fact that Russell has known for years that it is/was (see next paragraph) impossible to do so other than from within Safari.
Actually, it has recently become possible for Cookie to clear Safari's cache while it's running, but it remains impossible for it to clear its history, and despite that, the option, which is a flat out lie, remains.
And Russell's response to my requests that he remove the options/option was the same, "if no one wants this option [other than you], it’s not worth my effort."
Sorry, Russell, but HONESTY SHOULD BE INHERENT IN AN APP, NOT a feature that needs to be requested!
Other than that... GREAT APP!
