Private diaries aren't just about pretty interfaces—the key is how recording content is saved, whether it's used for ad profiling, and whether you can reliably retrieve it later.
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.
