privacy policy

last updated: may 2026

Hayley is built around a simple principle: what you say stays with you. This policy explains exactly what we collect, what we don't, and why.

voice and transcription

When you record a voice entry, your audio is transcribed in real time on your device using Apple's Speech Recognition framework (SFSpeechRecognizer). Your voice recordings are never stored, transmitted, or sent to any server. Audio exists only in memory during the recording session and is discarded immediately after.

ai insights

After transcription, the text of your entry is sent via an encrypted HTTPS connection to Anthropic's API to generate your insight, pattern, and question cards. This text is processed in real time and is not stored by Hayley beyond the duration of the API call. Anthropic's own data handling and privacy policies apply to this transmission. You can review them at anthropic.com/privacy.

local storage

Your journal entries, insights, and patterns are stored locally on your device using Apple's SwiftData framework. This data never leaves your device and is not accessible to us. If you delete the app, all data is permanently deleted.

analytics

We do not collect usage analytics, crash reports, behavioural data, or any form of telemetry. We have no visibility into how you use the app.

subscriptions

Subscription management, billing, and payment processing are handled entirely by Apple through the App Store. We do not collect, store, or have access to any payment information.

third party services

Hayley uses the following third-party services:

Anthropic Claude API — used to generate insights from your transcribed entries. Text is sent over encrypted connections and not retained. anthropic.com/privacy

Apple Speech Recognition — used for on-device voice transcription. Governed by Apple's privacy policy. apple.com/privacy

children

Hayley is not directed at children under the age of 13 and we do not knowingly collect data from children.

changes to this policy

If we make material changes to this privacy policy, we will update the date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
