Is my data collected?
No personal data, ever — no name, no email, no account, and nothing you write in the app. Your cards and settings stay on your device. Since version 1.14 the app can also record anonymous usage statistics to help us improve it, but only if you agree when asked at first launch; you can change your mind any time in Settings.
The Opener collects no personal data. Anonymous usage statistics are optional and off until you agree. Read our full Privacy Policy.
