The short version

• No sign-up. No email. No password.
• No third-party analytics (no Google Analytics, no Meta, no Mixpanel).
• No advertising — and no ad slot in the app to retrofit later.
• Affirmation prompts are held in memory for one request, then dropped. The generated audio is kept; the prompt isn't.
• Health data (heart rate, sleep stages) is read locally and used to drive the adaptive layer. Raw samples leave the device only if you opt in to research telemetry.
• Anonymous usage events (which buttons you tap, decode errors) are sent to our server for product improvement. No PII. Retained 90 days.
• The marketing site you're reading right now runs zero third-party scripts.

The long version

What identifies you to us

An anonymous UUID is generated the first time the app runs and stored locally. It's how your saved mixes, settings, and affirmation history get linked to "you" without an account. Re-installing the app generates a new UUID, so previously-generated custom affirmations will not be visible after a reinstall today. Cross-device persistence is on the roadmap.

What we send to our server

Telemetry events: which screen you opened, which sound you played, buttons you tapped, errors that occurred. Each event carries your anonymous UUID, the app version, and the platform (iOS / Android / Web). It does not carry an email, your name, your IP-mapped location, or the content of anything you typed. Retention: 90 days.

What we send to third parties

When you generate a custom affirmation, the prompt you typed is sent to AWS Bedrock (Anthropic Claude Haiku, hosted by AWS in us-east-1) and the generated text is sent to ElevenLabs for synthesis. We hold the prompt in our server's memory for the duration of the request and drop it afterwards; the generated audio file is kept on our CDN so you can replay it.

What we don't ask for

Microphone, camera, location, contacts, photos. Aviana does not request any of these permissions. Notification permission is asked only when you opt into the bedtime reminder or smart alarm.

Health data

With your permission, Aviana reads heart rate, HRV, and sleep stages from Apple HealthKit or Android Health Connect to drive the adaptive sound layer and the smart alarm. These values are read locally on your device. Raw samples are not transmitted to our server. Aggregated "did the adaptive layer help" signals can be sent if you opt into research telemetry — explicit toggle in Settings, defaults to off.

Cookies

The marketing site (this domain) sets no cookies and runs no first-party analytics. The app (app.aviana.life) sets one localStorage key for your anonymous UUID and one for your app preferences. No tracking cookies, no consent banner needed.

Children

Aviana is not directed at children under 13. We don't collect data knowing you're under 13. If you believe a child has used the app and you'd like the associated UUID deleted, write to privacy@aviana.life.
