As answered by people managing DeveloperTools.Tech and Try Conviction.
Try Conviction's answer:
Conviction aims to offer the same journal capabilities via a one-time fee for the pro tier only instead of an expensive subscription. At the same time Conviction is built to never have access to the users personal data and by default asks for usage statistics via opt-in instead of making it part of the terms of service.
Try Conviction's answer:
The combination of a full-scale journal with on-device AI capabilities without user data ever leaving the device at the fraction of the cost of other journal apps.
Try Conviction's answer:
People who want to utilize self-reflection tools for personal growth or working through their shadow patterns, who do not want to worry about their thoughts being exposed to any external party and who also do not want to pay another monthly subscription should try out Conviction.
