All your data lives on your device. iCloud sync is opt-in and end-to-end encrypted with a key only you hold.
App opens only with biometric unlock. Required by default for any new device.
No analytics SDKs. No advertising IDs. No Facebook pixel. No Google. Nothing leaves your device that you didn't ask to send.
Your data is never included in any training corpus, ours or a vendor's. AI features run on de-identified, on-device inference where possible.
Export every value, plan, and log to PDF or CSV at any time. Delete your account in two taps — every byte goes.
Built to meet UK GDPR data-subject rights and the Data Protection Act 2018. Annual third-party security review.
Most "private" apps still phone home for analytics. Aion's architecture makes that impossible — there's nowhere to phone.
Lab PDFs are parsed locally with Apple's Vision framework. The PDF itself never leaves your phone.
Local SQLite is wrapped in AES-256-GCM via CryptoKit. Keys are stored in the Secure Enclave.
Optional sync uses CloudKit's end-to-end encrypted record zones. Apple cannot read it; we cannot read it.
There's no Aion login. Your account is your iCloud account. We don't run a database of your data — there isn't one to breach.
By using Aion, you agree to the following. We've kept it plain — no legal jargon walls.
Aion helps you log and visualise your own health data. It does not diagnose, treat, or provide medical advice. See our medical disclaimer below.
Whether typed manually or extracted from a lab report, you're responsible for reviewing your data for accuracy before relying on it.
Aion and its team are not liable for decisions made based on data or trends shown in the app. Always consult a qualified healthcare professional.
You may delete your account at any time from Profile → Delete Account, which permanently removes your data. We may suspend accounts that violate these terms.
These terms are governed by the laws of England and Wales, and any disputes are subject to the exclusive jurisdiction of the courts of England and Wales.
Aion is a wellness app. It is not a substitute for medical advice, diagnosis, or treatment. Always seek the advice of a qualified physician with any questions you may have regarding a medical condition. Reference ranges and recommendations in Aion are educational, not prescriptive.
