Hufu Studio Apps

Hufu is the only secure messaging appthatgives you no-question-asked complete privacy protection,incombination with the best-in-class message encryption and asimpleand intuitive user interface. Unlike the mainstreamencryptedmessaging applications which demands your privateinformation likeyour phone number to sign up and use, Hufuencrypted messages passfrom your mailbox directly to therecipient's mailbox in the formof encrypted emails, which not justmakes it impossible for anyoneelse to read your conversations, butalso leaves absolutely zeroamount of your metadata and personalinformation to us. In fact, wedon't even run a server of any formand thus have no means to storeany of your data.__________________________________________HIGH STRENGTH END- TO-END ENCRYPTIONAll messages are encrypted before they leave your phone andnotdecrypted until they reach the receiver's phone, encryptionsareimplemented using highly secure and efficientindustry-standardalgorithms(128 bits AES-GCM for symmetricencryption, and 2048 bitsRSA for public key encryption ). Keys arestored locally in anencrypted database, with each page encryptedusing a separate key.Additionally, connections to the mail serversare protected withSSL/TLS whenever possible.__________________________________________COMPLETE AND PROVABLE PRIVACY PROTECTIONCiphertexts or plaintexts, all of your data belong to you!Hufunever connects to any server run by us(which can be easilyprovenby wiretapping your own connection or scrutinizing the code),thusthere is nopossibility we collect or store your data without yourpermission,or violate your privacy in any other way. All privatechat messagesare deleted from your mailbox 24 hours after theyarereceived/sent.__________________________________________MINIMALISTIC DESIGN AND INTUITIVE UICompletely private chat has never been easier as Hufumakesencrypted messaging a seamless experience in adecentralizedenvironment.

Settingup is a breeze, all cryptographic processeshappen under the hoodand are unnoticeable. It should take less thanminutes for a usercompletely new to Hufu to set up his Emailaccount and start usingHufu.__________________________________________ROBUSTNESSAny IMAP-supported mailbox can in theory be used withHufu,making it nearly impossible to censor all Hufu encryptedmessages,and the serverless and open source nature of Hufu allowsit tofunction independent of the status of our business.__________________________________________MINIMUM PERMISSIONSDevice & app history* retrieve running appsIdentity* find accounts on the devicePhotos/Media/Files* access USB storage filesystem* modify or delete the contents of your USB storage* read the contents of your USB storage__________________________________________OTHER* close other apps* full network access* view network connections* control vibration* use accounts on the device__________________________________________Precautions:1.
