Privacy Policy

Last updated November 9, 2026

This Privacy Policy explains how Sleepzly, a product of KSF CONSULTING LLC ("Sleepzly," "we," "us," or "our"), collects, uses, discloses, and otherwise processes information when you use the Sleepzly mobile application (the "App") and the website at https://sleepzly.com (the "Website").

Sleepzly is a relaxation and general wellness product. It is not a medical device or medical service, does not provide medical advice, diagnosis, or treatment, and is not intended to be HIPAA-regulated health care. If you have a medical concern, talk with a qualified clinician.

Who we are

Sleepzly is operated by KSF CONSULTING LLC. For privacy questions, email support@sleepzly.com.

Scope

This policy covers the App and the Website. Some practices apply only to the App (for example, Apple Health access or the microphone). Others apply only to the Website (for example, the launch-notification form and website analytics). Where a practice differs, we say so.

Information you provide

Account information. You can use the App with an anonymous account created for you, or you can link a Google or Sign in with Apple account. Depending on the sign-in method and what the provider returns, we may receive your email address, display name, and profile photo URL, and we store a unique user ID for your account.

Onboarding and preferences. You may provide preferences such as sleep struggles, goals, notification choices, and privacy toggles (for example, whether to save AI conversations or use entries for Sleep Memory).

Journal, check-ins, and notes. If you use journaling, nightly check-ins, tomorrow lists, or similar features, you may enter bedtime and wake times, sleep quality, stress or mood-related inputs, free-text notes, and related details.

Brain Dump and similar text. If you use Brain Dump or related writing features, you submit the text you type. That text may be stored in your account and may be sent to our AI providers when you request an AI summary or related assistance.

Website launch notifications. If you ask on the Website to be notified when Sleepzly launches or becomes available in stores, we collect the email address you submit, a timestamp, and optional page or campaign context (such as a path or UTM parameters). We use that information for product-availability messages you requested, not for third-party advertising.

Support. If you email us, we receive your email address, the message, and any details you include.

Information collected automatically

When you use the App or Website, we and our service providers automatically receive technical information such as device type, operating system, app or browser version, language, time zone, approximate region derived from network routing (for example, IP address), and diagnostic signals needed to operate and secure the service.

Sleep and wellness information

Depending on the features you use, the App may process sleep and wellness information such as sleep schedules, sleep duration estimates, consistency or sleep-debt style summaries, nightly check-ins, wind-down routines, listening history, and insights generated from information you keep in Sleepzly.

If you grant Apple Health access, the App may read sleep, heart rate, and related recovery metrics you allow, and may sync derived or snapshot data to your Sleepzly cloud account to power trends and optional personalization. Sleepzly does not write health data back to Apple Health. You can revoke Health access in iOS Settings.

Sleep and wellness information you store in your account is associated with your user ID. It is used to provide the features you choose, not to sell personal information.

AI Coach and AI-assisted features

Some App features use automated systems to generate or adapt content—for example AI Sleep Coach style guidance, personalized routines or stories, Brain Dump summaries, and the Voice Companion. When you use those features, relevant prompts, short context summaries (which can include wellness or preference signals you have allowed), and your messages can leave your device and be processed by our servers and AI providers so we can return a response.

These systems support relaxation and wellness experiences. They do not diagnose conditions or provide medical care. You can ignore any suggestion.

In-app settings may let you limit saving of AI conversations or exclude certain entries from Sleep Memory. Defaults may save helpful history until you change them. Turning a setting off does not by itself erase copies already stored with providers; see Account and data deletion.

Audio and voice processing

The App includes prerecorded relaxation audio (sounds, worlds, stories, and similar). Playing that library audio is not the same as recording your voice.

If you use Voice Companion, the App requests microphone permission, records a short clip on your device, and sends audio to our backend so it can be transcribed by our speech provider. Sleepzly is designed to delete the temporary on-device recording after processing and does not keep raw voice clips as a standard product archive. Transcripts and conversation summaries may still be stored locally and, if your settings allow, in your cloud account. Text-to-speech audio may be generated to play a reply.

Subscriptions and purchases

If you subscribe or buy through the Apple App Store or Google Play, payment is processed by Apple or Google—not by Sleepzly directly. We do not receive your full payment card number. We and our subscription partner (RevenueCat) receive limited purchase and entitlement information (such as whether Premium is active, product identifiers, and renewal-related status) so we can unlock paid features and troubleshoot access.

Analytics and diagnostics

App. The App uses Google Firebase Analytics to understand feature usage (for example app opens, screen or feature events, paywall and purchase funnel events) and Firebase Crashlytics for crash diagnostics. Analytics events may also be mirrored into your cloud account records used to operate the product. We do not offer a separate in-app “turn off all analytics” switch at this time; you can limit some related data through device settings and by limiting optional feature permissions.

Website. The Website uses Google Analytics 4 to measure aggregate traffic and key actions (such as page views and whether a launch-notification signup succeeds). Website analytics events are configured so they do not include the email address you type into forms.

Device and account identifiers

We use account identifiers (including Firebase user IDs for anonymous and linked accounts) and service identifiers issued by our providers (such as Firebase installation identifiers and RevenueCat app user IDs, which we align with your Firebase user ID). These identifiers operate the App, sync data, and measure reliability. They are not the same thing as selling your information to an advertising network.

How we collect information

We collect information:

How we use information

We use information to:

Service providers

We use companies that process information on our behalf to operate Sleepzly. Depending on the product surface, that includes:

Providers may process information in the United States and other countries where they operate. Their own privacy notices also apply to their services.

AI provider handling

When you use AI features, prompts, limited context, and—for Voice Companion—short audio clips are sent to our cloud functions and then to OpenAI so a response can be generated. Text generation uses OpenAI’s Responses API with store: false where that parameter is supported, so we ask OpenAI not to store those prompts/completions in its Responses store. Speech-to-text and text-to-speech use OpenAI audio endpoints that do not expose the same store flag. Our application logs are configured to avoid storing full prompt or transcript text. Setting store: false is not the same as Zero Data Retention; OpenAI may still process data for abuse monitoring or other purposes under its policies and our organization settings. Whether Zero Data Retention or Modified Abuse Monitoring is enabled for Sleepzly’s OpenAI organization is configured in the OpenAI dashboard and is not verified from application source code alone. We do not use your AI conversations to build third-party advertising profiles.

Data sharing

We share information with:

We do not sell personal information. We do not share personal information with third parties so they can advertise their own products to you.

Advertising and tracking

Sleepzly does not use third-party advertising networks to target you with third-party ads inside the App based on your sleep journal or AI conversations. We use first-party product and Website analytics to understand whether Sleepzly is working. “Tracking” under Apple’s App Store definition is a specific technical concept; our App Store privacy labels describe our practices for the App build you download.

Cookies and Website technologies

The Website may use cookies or similar storage for Google Analytics and for basic site operation where your browser allows it. The launch-notification form uses Cloudflare Turnstile to reduce automated abuse. You can limit cookies and site data in your browser settings. The App primarily uses platform SDKs and on-device storage rather than browser cookies.

Security

We use safeguards appropriate to a consumer wellness app, including encrypted transport (HTTPS / TLS) for the Website and App network calls to our backends. No method of transmission or storage is perfectly secure. We have not obtained a formal security-audit certification for Sleepzly, and this policy should not be read as one.

Retention

We keep information for as long as needed to provide the App and Website, maintain your account, secure the service, resolve disputes, and meet legal obligations. Exact periods vary by data type and provider. Purchase records held by Apple, Google, or RevenueCat follow those companies’ practices. AI provider retention follows provider policies and our configuration with them. Website launch-notification emails are kept so we can message you about availability unless you ask us to remove them.

Account and data deletion

In the App, Settings includes “Delete my data.” When Firebase is available, that control asks our servers to delete Sleepzly-held cloud data tied to your signed-in account (including your profile tree, AI usage counters we store, and related entitlement/referral records we control), then deletes the Firebase Authentication account, and clears local app data on the device. If cloud deletion cannot be completed, the App reports the failure and does not claim success. You may also email support@sleepzly.com to request access, correction, or deletion. We may need to verify that the request is yours.

We do not claim that Apple, Google, RevenueCat, OpenAI, analytics, crash-reporting, or other providers have deleted every copy they hold. Purchase and subscription records follow those companies’ retention rules. Some information can remain in backups, security logs, or provider systems for a period after deletion, or where we must retain it for legal reasons. Revoking Health or microphone permission in iOS Settings stops new collection from those sensors but does not by itself erase data already stored in your Sleepzly account.

Your privacy choices and rights

Depending on where you live, you may have rights to request access, correction, deletion, or information about our practices. Email support@sleepzly.com to make a request. We will respond as required by applicable law. The App also exposes privacy-related settings (for example, conversation saving and Sleep Memory inclusion) and export tools for certain on-device data.

International transfers

If you use Sleepzly from outside the United States, your information may be processed in the United States and other countries where we or our providers operate. Those countries may have different privacy laws than your own.

Children

Sleepzly is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has provided information, email support@sleepzly.com and we will take appropriate steps to delete it.

Changes

We may update this policy as the product, the law, or our practices change. When we do, we will change the "Last updated" date above. If a change is material, we may also post a notice on this Website or in the App. The version on this page is the current one.
