Privacy Policy

Last updated: August 14, 2026

This Privacy Policy applies to Tono: White Noise & Sleep Calm (package name com.tono.baby.sleep), published by Illia Shaikov ("Tono", "we", "our", or "us").

Overview

Tono is a baby-sleep and white-noise app intended for parents, guardians, and caregivers. Its core audio files are included in the app and can be played offline. Some features, including subscriptions, optional rewarded advertising, analytics, crash reporting, and links to external services, require an internet connection.

Tono does not require an account. Free users may voluntarily watch a rewarded advertisement to unlock a premium sound for a limited period. Tono Premium unlocks all sounds and removes advertising.

Information Stored on Your Device

Tono stores the following preferences locally on your device:

• selected theme and language;
• default and per-sound volume levels;
• saved mixes and selected sounds;
• sleep timer, delayed-start, and temporary sound-unlock settings;
• whether safety and onboarding messages have been acknowledged.

These preferences normally remain on your device and are removed when you clear the app's data or uninstall the app.

Information Collected or Processed

Tono does not ask you to create an account or provide your name, phone number, contacts, microphone recordings, camera content, or photos. If you contact us by email, we receive the contact information and message that you choose to provide.

Analytics and diagnostics

Firebase Analytics may process app opens, sessions, screen views, selected sound identifiers, timer and saved-mix actions, app version, device model, operating-system version, language, approximate region, and app-instance identifiers. We use this information to understand feature usage and improve Tono. Firebase Analytics is configured not to use its data for ad personalization.

Firebase Crashlytics may process crash stack traces, non-fatal error reports, app state, app version, operating-system version, device model, timestamps, and diagnostic identifiers. We use this information to find and fix stability problems.

Advertising

Tono uses CAS.AI mediation to provide optional rewarded advertisements to free users. CAS.AI and its advertising partners may process IP address and approximate location, device and advertising identifiers (including IDFA or Android Advertising ID when permitted), device and app information, advertising impressions, clicks and interactions, product interactions, performance data, diagnostics, and subscription or purchase-status data. This information may be used to deliver, measure, limit, secure, and personalize advertising, and to prevent fraud.

Advertising partners available through CAS.AI may include Google Ads, AppLovin, Meta Audience Network, Unity Ads, ironSource, Liftoff Monetize, InMobi, Mintegral, Pangle, Bigo Ads, CAS Exchange, YSO Network, Maticoo, and other demand partners enabled by CAS.AI. The partner that serves a particular ad may vary by country, device, consent status, and ad availability.

Subscriptions and purchases

Purchases are processed by Apple App Store or Google Play. We do not receive your payment-card or bank-account details. RevenueCat processes store receipts, product identifiers, purchase and subscription history, price and currency information, subscription status, an anonymous app user identifier, and related technical information to validate purchases, prevent fraud, restore access, and provide subscription analytics.

Advertising Consent and Your Choices

Where required, Tono presents a consent form before advertising partners use personal data. On iOS, Tono may also request permission through Apple's App Tracking Transparency framework before accessing the IDFA or tracking activity across apps and websites. Refusing tracking permission does not prevent you from using Tono; ads may instead be less personalized.

• On iOS, you can change tracking permission in Settings > Privacy & Security > Tracking.
• Where a privacy-options control is available in Tono, you can use it to review or update advertising consent choices.
• You can subscribe to Tono Premium to use all sounds without advertising.

Permissions

• Tracking (iOS): requested only to allow advertising partners to access IDFA and provide or measure personalized advertising.
• Notifications: used for media playback controls and background audio status on supported Android versions.
• Foreground service / media playback: used to keep audio playback stable when the screen is off or the app is in the background.
• Wake lock: used only as needed to keep audio playback reliable.

Tono does not request system permission for precise location. Advertising partners may infer an approximate location from information such as an IP address and may process other location information when available under platform rules, device settings, and your permissions.

Third-Party Services

Tono uses or may interact with the following service providers:

• CAS.AI Privacy Policy — advertising mediation and measurement;
• RevenueCat Privacy Policy — subscriptions, purchase validation, and entitlements;
• Firebase privacy and security information — analytics and crash reporting;
• Google Privacy Policy — Google services and Google Ads;
• Apple Privacy Policy — App Store purchases and Apple platform services.

Tono may also open system-provided app review, sharing, app-store, privacy, and subscription-management interfaces when you choose those actions.

Children's Privacy

Tono is intended for use by parents, guardians, and caregivers and is not directed to children. We do not knowingly ask children to provide personal contact information. Parents and guardians should supervise use of the app and any interaction with advertising or purchase flows.

Data Sharing and Sale

We do not sell personal information for money. We share information with service providers only as needed to operate subscriptions, analytics, diagnostics, support, and advertising. Advertising partners may process or share identifiers and activity for targeted or cross-context advertising where permitted by law and by your consent. Such activity may be considered a "sale" or "sharing" under certain privacy laws even though we do not receive money in exchange for your personal information.

Data Retention and Deletion

Local settings remain on your device until you delete them, clear app data, or uninstall Tono. Firebase, CAS.AI, advertising partners, Apple, Google, and RevenueCat retain information according to their own policies and our configured service settings.

If you contact us for support, we use your message only to respond and maintain necessary support records. You may request deletion of support information you provided by emailing us. Because Tono does not require an account and many service identifiers are anonymous, we may need additional information to locate a particular record, and in some cases may not be able to associate anonymous records with you.

Security and International Processing

We and our service providers use reasonable technical and organizational measures to protect information. No method of electronic transmission or storage is completely secure. Service providers may process information in countries other than the country where you live, subject to their legal and contractual safeguards.

Changes to This Policy

We may update this Privacy Policy from time to time. Updates will be posted on this page with a new "Last updated" date.
