Hushio Privacy Policy

Effective date: October 25, 2026.
Operated by Hushio ("we"). Contact: support@hushio.app.

This policy covers Hushio: Sleep Sounds Mixer. We have no ads, do not sell your data, and do not track you across apps.

Accounts and saved mixes

Sign in with Apple is optional: tap Not now to continue. Supabase still creates an anonymous app user ID. Supabase and RevenueCat use your app user ID to run account and subscription features.

Supabase stores your saved mixes (up to 200), including their settings and any saved prompt, and your Smart Mix consent record. If you sign in with Apple, Supabase also stores your real or relay email and a server-side sign-in token so we can revoke access when you delete your account. Full quiz answers stay on your device; see Smart Mix below for sound preferences derived from them.

Optional Smart Mix

We ask permission before the first request. Choose Not now to decline; we ask again if the disclosure version or provider changes.

When you use Smart Mix, the text you type and the sound preferences from your quiz are sent through Supabase to OpenAI, an AI service, to choose sounds from our catalog. The request also includes catalog tags and, when provided, your current mix. We do not attach your name, email, account ID or device ID. Avoid putting personal information in your prompt: whatever you type is sent.

OpenAI's API data-controls wording, checked October 25, 2026:

As of March 1, 2023, data sent to the OpenAI API is not used to train or improve OpenAI models (unless you explicitly opt in to share data with us). By default, abuse monitoring logs are generated for all API feature usage and retained for up to 30 days, unless longer retention is required by law, or is reasonably necessary to protect our services or any third party from harm.

Payments, usage and diagnostics

• Apple and RevenueCat handle subscriptions and purchase history. We never see your card details.
• Supabase uses your IP address to limit anonymous sign-ups to 10 per IP per hour. It also stores Smart Mix usage and cost records to enforce limits.
• PostHog receives limited interaction events, such as screen visits, playback and subscription events, with an anonymous install ID. We do not identify your app account to it. Automatic capture, session replay, screenshots, IP capture and location lookups are off.
• Sentry receives crash, error and performance data with an install ID, without an account identity. Screenshots and view-hierarchy attachments are off.

PostHog and Sentry do not receive prompt text, quiz answers or email. Server logs exclude prompt text, emails and tokens. We do not collect advertising identifiers or location data.

Age

Hushio is intended for people aged 13 and older. We do not knowingly collect data from children under 13. If you believe a child under 13 has used Hushio, contact us and we will delete the account.

Keeping and deleting data

• Guest (anonymous) accounts with no activity for 90 days are deleted automatically.
• IP addresses used for sign-up rate limits are kept for 24 hours.
• Smart Mix usage and cost records are kept for 13 months.
• PostHog analytics are kept for 1 year; Sentry crash reports for 90 days.
• Database backups are kept for 7 days.
• When you delete your account, your data is removed within 30 days, including from backups.

Email and saved mixes are kept until deleted. Delete account works for anonymous and Apple sign-in users. It removes the account, saved mixes, RevenueCat subscriber record and PostHog person record, clears local mixes, and revokes the Apple token if used.

Smart Mix cost and usage history remains linked to the original purchase transaction ID, with your app user ID removed, so deletion does not reset usage limits. Apple retains its own purchase records. Deleting your account does not cancel your subscription; cancel separately in Apple's subscription settings.
