Features that need permission

The browser or phone asks the first time you use each one. If you said no by mistake, allow it again in your browser's site settings for kretaos.com, then try again.
Good to know
- Long meeting recordings. In a phone's browser, recording stops when the screen locks, so record long meetings from a computer and keep the recording tab open. See Record a meeting.
- Recording in other browsers. If a browser cannot record audio, KretaOS says so and suggests Chrome or Safari.
- Push on iPhone. In Safari, add KretaOS to your Home Screen first, then turn notifications on from there. See Notifications and push.
- Cookies. KretaOS uses only the essential cookies that keep you signed in. Blocking all cookies for kretaos.com will stop you signing in.
- Light theme. KretaOS has one light theme, designed for reading long client histories comfortably.
