Diaries usually contain real relationships, locations, emotions, and life details. Before choosing, confirm whether the app provides account cloud sync, has cloud AI inference, integrates third-party ad SDKs, and whether diary content is saved on device or server by default.
Lockeep uses local-first product boundaries—the current version does not include developer accounts, cloud sync, or cloud AI inference. It's better suited for users who want to preserve diaries as long-term private assets and need voice recording, on-device AI processing, and calendar review.
See Private Diary App, Privacy Policy, and FAQ for more specific data processing boundaries.
