Ears Up - Privacy Policy Supplement

Effective Date: July 11, 2026 Last Updated: July 11, 2026

This Privacy Policy Supplement is specific to Ears Up and supplements WagDev LLC's general Privacy Policy and Data Security Standards.

1. Summary

Ears Up is a single-user daytime-sleepiness self-check-in app. Your check-in content is stored only on your device. Everything you record — your check-ins, sleepiness ratings, notes, and any reminder schedule you set — is stored locally on your device in an encrypted database and never leaves it. There is no account, no login, and no cloud. We do not operate a server, we do not run analytics on your check-in content, and we do not have a copy of your check-in data anywhere.

Two narrow outbound data flows leave your device, disclosed in detail below. Neither one receives your check-in content:

2. Data Collection

2.1 What You Provide

All of the following is stored exclusively on your device in an encrypted local SQLite database (SQLCipher):

We never see, transmit, or store any of this check-in content on our infrastructure, and it is never shared with AdMob or any advertiser.

2.2 What Ears Up Does Not Collect

2.3 What AdMob Collects on Google's Behalf

Ears Up is supported by banner advertisements. When you use Ears Up, the embedded Google Mobile Ads SDK collects the following for ad serving and measurement — not your check-in content:

The full disclosure of AdMob data practices appears in Section 4.3 ("Advertising in Some Apps") of the WagDev Privacy Policy, which is incorporated here by reference. Your AdMob data is governed by Google's privacy policy.

2.4 What Sentry Collects for Crash and Error Reporting

To diagnose and fix bugs, Ears Up integrates Sentry — a crash and error reporting service operated by Functional Software, Inc. (d/b/a Sentry). When the app encounters a runtime error or crash, the Sentry SDK transmits:

What Sentry does not receive from Ears Up:

Sentry crash and performance reporting is gated off entirely in development and end-to-end test builds, so it only operates in released production builds. Sentry data is retained per Sentry's data retention policy and governed by Sentry's privacy policy. The full disclosure of how WagDev uses Sentry across apps appears in Section 4.2 ("Service Providers") of the WagDev Privacy Policy.

3. How Ears Up Uses Your Data

3.1 Local Use Only

Your check-in data is used solely to power the app's features on your device:

No remote processing, no machine learning on your content, no human review.

3.2 No Cross-Device Sync

Because Ears Up does not have a server or an account, your check-in data does not sync between devices. If you install Ears Up on a second device, you will start fresh on that device. If you delete and reinstall Ears Up on the same device, your local data will be erased (see Section 5 below).

4. Data Sharing

4.1 We Do Not Share Your Check-In Data

4.2 AdMob Receives Only Ad-Serving Data

AdMob receives only the data categories listed in Section 2.3 above. It does not receive your check-in ratings, notes, schedule, or any content you create in the app.

4.3 Sentry Receives Only Diagnostic Data

Sentry receives only the data categories listed in Section 2.4 above. Our SDK configuration disables PII collection, performance traces, and session tracking. Sentry receives no check-in data of any kind.

5. Your Privacy Controls

5.1 On-Device Controls

Because all of your check-in data is local to your device, you have direct control:

5.2 Advertising Controls

The app remains fully functional whether or not you grant ad tracking permission.

5.3 Data Export

Ears Up does not currently offer a built-in data export. Because your check-in data lives only on your device, you cannot lose it to a server outage — but you also cannot retrieve it if your device is lost. Back up your device using its native backup system (iCloud Backup, Google One Backup) to preserve your Ears Up data.

6. Data Retention

6.1 As Long As You Have the App

Your check-in data is retained on your device for as long as you have Ears Up installed and your device's storage permits. We do not impose any time-based retention limits because we never receive your check-in data.

6.2 After Uninstall

Uninstalling Ears Up removes the app's encrypted SQLite database from your device. Because we never received your check-in data, there is nothing for us to delete on our side. Ad-related data already collected by AdMob remains subject to Google's retention practices, which you can review and manage at adssettings.google.com.

7. Children's Privacy

Ears Up is not directed to children under 13 and we do not knowingly collect any personal information from children under 13. Because Ears Up has no account system and collects no personal identifiers of its own, there is no profile to create. AdMob is configured with "treat as child-directed" set to No, meaning Ears Up is not designated as a child-directed app under COPPA. Parents who believe their child under 13 is using Ears Up should uninstall the app, which removes all local data.

8. Security

8.1 On-Device Security

Your Ears Up check-in data is stored in an encrypted local database using SQLCipher (via expo-sqlite), layered on top of Apple's and Google's standard application sandboxing. We also rely on:

Because Ears Up has no network sync of your check-in content, there are no transit-layer security concerns for that content.

8.2 AdMob and Sentry Security

Data sent to AdMob is encrypted in transit using TLS by the Google Mobile Ads SDK. Crash reports sent to Sentry are likewise encrypted in transit using TLS.

9. Compliance Notes

9.1 Apple App Privacy Details

The following data types are declared in Ears Up's App Store privacy nutrition labels, consistent with the app's iOS privacy manifest:

No data from your check-in content is declared, because no check-in content is collected off your device.

9.2 Google Play Data Safety

The Google Play Data Safety section declares the AdMob categories above (device or other IDs, app activity / advertising data, and approximate location for advertising) plus the Sentry diagnostics categories, a "Data is encrypted in transit" affirmation, and a "Users can request data deletion" affirmation pointing to the uninstall path in Section 5.1. Sentry crash data is declared as Diagnostics → Crash logs, not linked to a user.

10. Changes to This Supplement

If we materially change how Ears Up collects or uses data, we will bump the version of this document and update the Last Updated date. Continued use of Ears Up after a change indicates acceptance of the revised supplement.
