SleepBlend AI
Most sleep-sound apps hand you a wall of soundscapes and leave you scrolling at midnight. SleepBlend AI is a calm sound console instead: compose tonight's nocturne from a handful of voices — rain, ocean, wind, coloured noise, a warm drone — each generated on your device in real time, with its own volume and stereo balance, and no downloads. The Resonance Ring shows the blend as bands of light around a still centre; when the voices sit in balance it settles into an even halo and glows green. Begin the nocturne, set a gentle sleep timer, and in the morning give one honest check-in — how fast you drifted off, how rested you feel. From that, and only that, SleepBlend learns: the Sleep Mix Score reflects how each blend works for you (never a sensor, never a measurement), it surfaces which voices go with your easier nights as honest associations, and it recommends tonight's best blend. The full mixer stays free, with room to save a few favourite blends — Pro unlocks all fifty premium voices, unlimited saved blends, the adaptive recommendations, and the deeper insights. A wellness companion for a calmer wind-down, not a medical device.

Privacy Policy

Effective July 27, 2026 · Last updated September 14, 2026

Christian Harvey-Michael ("we", "us") operates the SleepBlend AI mobile application (the "App"). This policy explains what we collect, how we use it, and the choices you have.

Information we collect

What we do not collect

We do not collect your location, contacts, photos or media files, or advertising identifiers, and we do not use any third-party advertising or behavioral-tracking SDKs. We do not track you across other apps or websites.

How we use information

To provide and maintain the App, authenticate you, sync your content to your account, and respond to support requests. We do not use your content for advertising.

Storage, security & processors

Your data is stored with our cloud backend (Supabase), isolated per user with row-level security so that only you can access your own data, and transmitted over encrypted connections (HTTPS/TLS). We share data only with the limited service providers needed to run the App — our cloud hosting and authentication provider, and Apple (for any purchases). To confirm whether a purchase is active we use RevenueCat, which receives an app user identifier (a random one before you sign in, and your account's internal ID after — never your name or email), the purchase details Apple provides, and basic device information such as platform, operating-system version, and country. We do not sell your personal information.

No method of storage or transmission is completely secure, so while we work to protect your information we cannot guarantee absolute security.

International users

Our service providers may process and store information on servers in the United States or other countries, whose data-protection laws may differ from those where you live, under the terms of those providers.

Data retention & deletion

We retain your data while your account is active. You can permanently delete your account and all associated data at any time from within the App (Settings → Delete Account). Deletion removes your account and content from our systems.

Records of purchases are kept by Apple, and subscription status by RevenueCat, under their own policies, because they are needed for billing, entitlement, and tax purposes. Deleting your account does not delete those records, and it does not cancel an active subscription — cancel that in your Apple ID settings.

Children

The App is not directed to children under 13, and we do not knowingly collect personal information from them.

Your choices

You can access, correct, or delete your data using the in-app controls, or by contacting us at kaspyr2000@hotmail.com.

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal information, to object to or restrict certain processing, and to complain to your local data-protection authority. Most of this you can do with the in-app controls; for anything else, email kaspyr2000@hotmail.com and we will respond as required by applicable law.

These pages

These Privacy, Terms, and Support pages are static: they set no cookies and load no analytics, advertising, or third-party scripts. Our hosting provider may keep standard request logs (such as IP address and browser type) to serve the pages securely and diagnose faults. If you email us, we keep your message and address only to reply and help you.

Changes

We may update this policy from time to time; material changes will be reflected by a new effective date above.
