Why SentiLog exists: because your diary is not an ad-targeting dataset.

Warum SentiLog existiert: Dein Tagebuch ist kein Datensatz für Werbung.

なぜSentiLogが存在するか:あなたの日記は広告ターゲティングのデータではありません。

SentiLog가 존재하는 이유: 당신의 일기는 광고 타겟팅 데이터가 아닙니다.

Other journaling apps sync your entries to their servers. Some process your text with cloud AI. SentiLog runs its AI entirely on your phone — no internet, no server, no exceptions. Your words are encrypted with AES-256 before they touch storage. The AI model lives in the app itself. We have no technical ability to read your journal even if we wanted to. That is by design.

Andere Tagebuch-Apps synchronisieren deine Einträge auf ihre Server. SentiLog läuft vollständig auf deinem Gerät — kein Internet, kein Server, keine Ausnahmen. Deine Worte werden mit AES-256 verschlüsselt, bevor sie gespeichert werden.

他の日記アプリはサーバーにエントリを同期します。SentiLogは完全にあなたのスマートフォン上で動作 — インターネットなし、サーバーなし、例外なし。AES-256で暗号化。

다른 일기 앱은 서버에 항목을 동기화합니다. SentiLog는 완전히 기기에서 실행 — 인터넷 없음, 서버 없음, 예외 없음. AES-256 암호화.

"I tried five journaling apps. They all felt like I was writing into someone else's server. With SentiLog the AI runs on my phone — I checked in Settings and there is zero network traffic during analysis. I write things now I never would have typed into the others."

„Ich habe fünf Tagebuch-Apps ausprobiert. Bei allen hatte ich das Gefühl, in den Server von jemand anderem zu schreiben. Bei SentiLog läuft die KI auf meinem Telefon. Ich schreibe jetzt Dinge, die ich in die anderen nie getippt hätte."

「5つの日記アプリを試しました。どれも誰かのサーバーに書いているような感覚でした。SentiLogはAIがスマートフォン上で動作します。今は他のアプリには絶対書かなかったことも書けます。」

"다섯 가지 일기 앱을 써봤습니다. 모두 다른 사람의 서버에 쓰는 것 같았어요. SentiLog는 AI가 제 폰에서 실행됩니다. 이제 다른 앱에는 절대 쓰지 않았을 것들도 쓸 수 있어요."
