Does my data leave my iPhone?

No, unless you enable iCloud sync. Your thoughts stay on your iPhone by default. If you turn on iCloud, they are encrypted before leaving your device, with keys kept in your iCloud Keychain, so Apple cannot read them.

How much does Reteum cost?

Reteum is free for your first 100 thoughts with all features. Reteum Pro is $24.99 per year and adds unlimited thoughts and import capability.

Do I need to create an account?

No. There is nothing to sign up for and no Reteum server. You can start using the app immediately without any account or login.

Private notes and journal app for iPhone with on-device AI, end-to-end encryption, and semantic search that works offline.

Overview

A look at reteum.com

Reteum is a private notes and journal app for iPhone designed around how memory works. Users can capture thoughts through typing, voice or photos from anywhere—via widget, lock screen, control center or Siri—and the app brings back relevant memories, searches by meaning rather than exact words, and automatically organizes thoughts into connected subjects.

Both AI models run locally on your iPhone, even in airplane mode, ensuring complete privacy. Your thoughts never leave your device unless you enable iCloud sync, which encrypts everything before it leaves your phone. There is no account to create, no Reteum server, no analytics or tracking. The free version supports up to 100 thoughts; Reteum Pro adds unlimited thoughts and import capability.
