KĒPS
Read full descriptionHide full description
KĒPS™ is Virtual Private Messaging™: end-to-end encrypted messages, photos and calls that delete themselves on the schedule you choose. No account. Nothing stored. No trace — just you and the people you choose. PRIVACY YOU OWN No username, email or phone number is needed to download or use KĒPS, and KĒPS never looks in your contact list. There is nothing to sign up for, and nothing to leak. END-TO-END ENCRYPTED Messages, photos, GIFs, voice messages, PDFs and calls are encrypted on your device, so only the people in the conversation can open them. The KĒPS Relay™ passes them along without the keys to read them, and keeps none of them. MESSAGES THAT DELETE THEMSELVES Choose how long messages, photos, voice messages and PDFs last after they're opened, and when unopened ones expire — from 2 minutes to 24 hours. Your settings travel with every message you send, so your contact's phone deletes your messages on your terms. CONNECT WITH A PRIVATE LINK Create a Share Link and send it to the person you want to talk to, any way you like, or swap a 6-digit code when you're together. The contact exists only in KĒPS, and you name it whatever you want, so only you know who you're talking to. Matching verification images let you confirm it's really them. ENCRYPTED VOICE AND VIDEO CALLS Call any of your KĒPS contacts by voice or video. Every call is end-to-end encrypted with a fresh key that is thrown away when the call ends. Keep chatting during the call without leaving it. SHARE WITHOUT GIVING IT AWAY Photos, GIFs, voice messages and PDFs go only to the person you send them to — never to a cloud album, a streaming host or us. PDFs open in KĒPS's own viewer, and you decide whether your contact can save what you send. Share links, photos and PDFs into KĒPS straight from other apps. MORE • React to messages with a tap • Screenshots and screen recordings of your conversations are blocked wherever iOS allows it • Lock KĒPS with Face ID or Touch ID • Works on iPhone and iPad What happens in KĒPS, stays in KĒPS. KĒPS is free. The free plan shows non-personalized ads; an optional ad-free subscription removes them. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings at any time. Privacy Policy: https://www.kepsecure.com/privacy Terms of Use: https://www.kepsecure.com/terms KĒPS is made by KEPS Inc.

Most messaging apps are built to reach anyone. Kibu is built for the people you trust most. Kibu is a private, end-to-end encrypted space for your closest relationships. Group chats, direct messages, and calling, shared only with the people who belong there. HUMANS ONLY No bots, no spam, no ads, no strangers. Kibu is invite-only, and every member is a real person. With Kibu, you always know exactly who you're talking to. PRIVATE, SECURE CHAT Your group chats, direct messages, and calls are all end-to-end encrypted, from messages to files and everything in between. Only the people in the conversation can see what's shared. FULL TRANSPARENCY Nothing leaves a chat quietly. Screenshots, copied text, and exported files all notify the chat, so nothing gets shared without everyone knowing. GROUPS, GOVERNED TOGETHER In group chats, changes happen together, not by any one person alone. Important actions like adding members and changing settings go to a vote. • Assign Admin and Member roles to match how your group works • Require a majority, unanimous, or a set number of approvals • Invite people already on Kibu, or bring people in by link or QR code SECURE BY DESIGN • Your account lives on your device, not behind a username, password, or phone number. • Only you can get in. Your account unlocks with your face, on your device, and nowhere else • Per-chat notification controls keep sensitive conversations off your lock screen. Kibu is invite-only — you'll need an invitation or an organization to get started. Questions or feedback? We'd love to hear from you. contact@kibu.us
