Creating uses tokens: get them with a subscription (Basic, Plus, Pro) or buy a top-up pack. The subscription renews automatically until you cancel it in your App Store account settings. What you create in these sections is not protected by end-to-end encryption; this is explained in detail in the Privacy Policy. NOTHING EXTRA - Instant notifications that are easy to turn off - Mute or snooze notifications for any chat - Light and dark themes - A light app: it starts fast and is easy on the battery PRIVACY Katt does not ask for unnecessary permissions. There are no ads, and your conversations are not used to build a profile of you. All data travels over a secure connection, and messages are available only to you and the person you are talking to. Sign-up takes a few seconds. Find your contacts and start talking. Privacy Policy: https://katmessenger.com/#privacy Terms of Use: https://katmessenger.com/#terms
