Privacy Policy

• Slate Journal

Last updated: April 2026

The short version

Almost everything you write and record in Slate Journal stays on your device. The only time data leaves your device is when you explicitly use an AI feature, or when you choose to share an entry with someone in your circle. We don't have accounts, we don't run analytics, and we don't sell anything about you to anyone.

What we collect and where it lives

What stays on your device — always

• *Journal entries and recordings. Everything you write or record is stored locally in the app's private storage on your device. Audio files, transcriptions, summaries, tags — none of it is sent to our servers unless you take an explicit action described below.
• *App settings. Your preferences (notification times, journal names, lock settings, etc.) are stored in your device's local storage.
• *Transcriptions. Voice entries are transcribed on-device using Apple Speech Recognition. Your audio never leaves your device for transcription.

What leaves your device — only when you ask

• AI features (Summarise, Reflections, Narrative)

When you tap an AI feature, the text of the relevant journal entries is sent to OpenAI's API to generate a response. We do not store this text on any Slate server. OpenAI processes it according to their own privacy policy. We recommend not using AI features on entries containing sensitive personal information (passwords, financial details, medical records) as a precaution.

• Circle (sharing with friends)

If you use the Circle feature, invite voice notes and entries you explicitly share are stored in Apple's CloudKit infrastructure. This data is governed by Apple's privacy policy. Only you and the specific people you share with can access it — there are no public profiles and no discovery features.

What Apple handles on our behalf

• *Purchases. Slate Pro is sold through Apple's App Store. Apple processes all payments. We never see your payment information.
• *iCloud sync (if enabled). If you turn on iCloud backup in Settings, your journal database is synced via iCloud. This is governed by Apple's privacy policy.
