App, privacy & security overview

Communication built around who you are right now.

Learn how Krew combines passcode-routed identity spaces, private communication, social features and layered security controls.

01

App overview

Krew connects messaging and identity.

People already live in multiple roles. Existing messengers generally bind those roles to a phone number, account or flat inbox. Krew makes context a first-class product object.

Structural privacy

Separate contexts by design instead of asking users to hide individual conversations after the fact.

Lower switching friction

Move between roles without another SIM, another device or a cloned app.

Profile-aware graph

Chats, circles, stories and posts can inherit the same active identity boundary.

Everyday usability

Users can message, call, share and participate without leaving the active identity.

02

Signature experience

Passcode-routed profiles are more than account switching.

A numeric passcode maps directly to a specific profile. Entering it can open the right identity without first revealing a list of every private space.

  1. 01
    Secure the main profile

    The main passcode establishes the root boundary.

  2. 02
    Create named spaces

    Each sub-profile receives a unique 4–12 digit passcode and its own identity.

  3. 03
    Unlock by intent

    The passcode routes the user to the matching profile; duplicates are rejected.

  4. 04
    Keep communication in context

    Profile-aware chats and social activity maintain the boundary after entry.

03

Practical use cases

Useful wherever mixed contexts create daily friction.

Business

Owner / operator

Separate customers, vendors, colleagues and personal relationships while keeping one device.

Students

Teenager / student

Move between family, school, close friends and interests with less accidental exposure.

Creator

Community lead

Maintain a public identity while preserving private circles and personal conversations.

Household

Shared-device user

Reduce casual access when a phone is borrowed by a family member or colleague.

05 / APP COMPARISON

Different products with different strengths.

Krew focuses on context separation. WhatsApp and Telegram retain important strengths in cryptography, scale and cross-device ecosystems.

Krew’s distinction is contextual access separation, not a claim of stronger message cryptography. Comparison reflects official Meta/WhatsApp and Telegram materials reviewed 14 July 2026; availability may vary by platform and region.

06

Security architecture

Current controls and the next security milestone.

Krew already protects identity boundaries, stored message text and live call transport. The next trust milestone is independently reviewed end-to-end encryption designed so message content is readable only on participant devices.

VerifiedProfile passcodes are stored as one-way password hashes.
VerifiedMessage text is encrypted by the server before database storage.
VerifiedWebRTC media transport uses encrypted SRTP channels with DTLS keying.
VerifiedNo server-side call recording or call-media archive was found.
ImportantLocal call-history metadata is retained for the Android Calls view.
Security development priority

Implement a mature E2EE protocol for messages, secure device linking and recovery, minimize metadata, commission independent review, and publish a clear security model before making a default-E2EE claim.

07

Security improvements

Build security that is testable and documented.

01
transport

Require secure production connections

HTTPS, WSS and authenticated, rotating TURN credentials.

02
messages

Implement mature E2EE

Forward secrecy, per-device keys, verification and secure group key management.

03
privacy

Minimize metadata

Document retention limits for logs, push payloads, IP information and location data.

04
assurance

Commission independent review

Publish the security model, threat model and remediation summary.
