Privacy Policy for Sleep Calculator - Sloth (Mobile App)

Published by: ChromiumOne
At ChromiumOne, we respect your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when using the Sleep Calculator mobile app.

1. Overview & What This Policy Covers

This policy applies solely to the mobile version of the app. It describes what data the app collects (if any), how it is used, whether it is shared with third parties, and how you can control or request deletion of such data. It also explains how advertising is served via third-party ad networks (such as Google AdMob) and how data related to ads and analytics may be collected.

2. Data Collection & Use

a) Data You Provide Directly

The core sleep-calculator functionality does not collect or store any personally identifiable information (PII). All sleep-time inputs and calculations remain local to your device — nothing is sent to our servers.

b) Data Collected by Third-Party Ad / Analytics SDKs

Because the mobile app integrates the Google AdMob SDK to serve ads, third-party code may automatically collect certain device or usage data to enable ad delivery, performance measurement, and analytics. According to Google's disclosures, the SDK may collect data such as device identifiers, IP address, performance data, advertising IDs (or equivalent), and user interactions. This data may be used for:

  • Displaying ads (contextual or targeted, depending on consent)
  • Advertising measurement and analytics (impressions, clicks, performance)
  • SDK operation and performance optimization

Data collected by third-party partners is governed by their own privacy policies.

3. Tracking & Consent (App Tracking Transparency for IOS)

If the app requests permission under Apple’s App Tracking Transparency framework, you will be prompted to allow or decline tracking.

  • If you allow tracking: AdMob and other SDKs may use collected data to target ads or measure ad performance.
  • If you deny tracking: The app will function normally but only non-personalized or less personalized ads will be shown, and tracking/targeted advertising will not occur.

4. What We Do Not Collect / Store

We do not collect or store any personally identifiable information (name, email, address, etc.) as part of the core sleep-calculator functionality. We do not collect or store sleep data on a server — all calculations remain completely local to your device.

5. Data Protection & Third-Party Partners

We rely on third-party providers (e.g., advertising networks) for ad delivery and analytics. Any third party with whom data is shared must provide equal protection of user data in accordance with this policy and App Store and Play Store requirements. We encourage users to review the privacy policies of these partners (e.g., Google AdMob) for details about their data collection and processing.

6. Your Rights & Controls

You have the following rights and control options:

  • You can choose whether or not to allow tracking via the system consent prompt.
  • You can opt out of personalized ads where supported (e.g., Google Ads Settings).
  • Because the app does not collect or store PII or server-side data, there is no personal data stored by us to delete.
  • You may contact us with any questions or privacy concerns at our support email.

7. Children & Sensitive Data

The app is not specifically designed for children under 13 (or any age defined by applicable law). We do not knowingly collect personal data from children. The app does not request or access sensitive data such as health data, medical data, or precise location. All sleep-time inputs are processed entirely on-device.

8. Changes to This Policy

We may update this Privacy Policy periodically—for example, when adding new features, integrating new third-party SDKs, or modifying data collection practices. Updates will be reflected here with an updated “Last updated” date.
