Aurnia

Effective: 2026-04-28 · Last updated: 2026-10-02

Aurnia ("we", "our") is published by OOTSSU. This policy describes what data Aurnia collects, why, and how to remove it. You can use Aurnia without an account; an account is only needed for the AI Morning Brief.

What we collect

• Apple HealthKit data (sleep analysis, HRV, resting heart rate) — read-only, processed and stored on your device.
• Sleep records and journal (nightly summaries, mood, factor tags, free-text notes) — stored only on your device. They are not uploaded to our servers.
• Account (optional) — only if you sign in with Apple, Google or email. Our authentication provider (Supabase) keeps your login (email address or provider identifier), and Aurnia keeps a profile row with a one-way hash of your email. The account is used for the AI Morning Brief and to keep your subscription with you.
• AI Morning Briefs — generated with Anthropic's Claude for Pro subscribers who allow AI processing. The brief text is stored on our server with your account, one per night, so it is not generated twice.
• Usage counters — a daily count of AI brief requests per account, and for requests whose subscription status cannot be verified, a salted one-way hash of the network address. They are used to enforce fair-use limits and contain no health data.
• Purchases — processed by Apple and managed through RevenueCat, which receives a random account identifier and your purchase history.

Aurnia does not use the microphone and does not record or analyze audio.

AI processing (third party)

Before the first AI Morning Brief, Aurnia asks for your permission. If you allow it, each brief sends these values through our aurnia-coach server function to Anthropic (Claude): last night's date, sleep duration, sleep stages, HRV and resting heart rate; your recent baseline (typical HRV, resting heart rate and sleep length over up to 14 nights); today's journal mood and factor tags; and your language. Never sent: journal notes, audio, location, your name or email. While your baseline is still calibrating (fewer than 7 nights), the summary is created on your device and nothing is sent. You can turn AI processing off at any time in Settings → Account → "Share sleep summary with AI".

These values are biometric readings tied to your account in our own systems, so we call them pseudonymised rather than anonymous — they remain personal data. Anthropic deletes request inputs and outputs within 30 days under its standard commercial API terms; we do not hold a zero-data-retention agreement.

Deleting your data

With an account: Settings → Account → Delete account. This immediately deletes your Aurnia profile and AI briefs from our server and erases the sleep records and journal stored in Aurnia on your device. Your login record is deleted as well, unless the same login is still used by another OOTSSU app — then it stays for that app. Daily AI usage counters (no health data) are kept while the login exists, so deleting and re-creating Aurnia data cannot reset fair-use limits.

Without an account: nothing about you is stored on our servers. Settings → Account → "Delete data on this device" erases Aurnia's records on this device; deleting the app removes them too.

Deleting data does not cancel a subscription — cancel it in iPhone Settings → [your name] → Subscriptions. Step-by-step instructions: Delete your account & data.

Tracking

Aurnia does not track you across other apps or websites and does not show advertising. We do not sell personal information.

Children

Aurnia is not directed to children under 13. We do not knowingly collect data from children under 13.
