Workstamp Privacy Policy

Effective date: July 13, 2026 · Last updated: August 10, 2026

Workstamp ("the App") respects your privacy and complies with applicable laws. This policy explains what information the App processes and how.

1. Operator & Contact

Operator: JJ Company (제이제이컴퍼니)
Contact: support@jjworks.dev

2. Information We Do Not Collect

The App has no sign-up or login, and does not collect personally identifying information such as your name, email address, or phone number.

3. Information Stored Only on Your Device

Data you enter — attendance records, work schedules, goals — is stored only in local storage on your device and is never transmitted to the operator's servers. Deleting the App also deletes this data.

4. Information Collected Automatically via Third-Party Services

The App uses the following Google services, which collect and process certain information.

Service	Information collected	Purpose	Third party
Firebase Analytics	App interaction events, approximate location (derived from IP), device and installation identifiers	Usage analysis and improvement	Google
Firebase Crashlytics	Crash logs, diagnostic information	Stability improvement	Google
Firebase Remote Config / Installations	Delivery of remote configuration values; device, language, region, and installation identifiers	Remote configuration	Google
Google AdMob	Advertising identifier, device information, approximate location	Ad serving	Google/AdMob

The App does not track users across apps. It does not request iOS App Tracking Transparency (ATT) permission, and does not use the advertising identifier (IDFA) for tracking purposes. Ads shown in the App are non-personalized.

Advertising identifiers and device information may be processed by a third party (Google/AdMob) for the purpose of serving ads.

Data handling by these services is governed by Google's Privacy Policy and Google's partner policies.

5. Advertising & Consent (EEA, UK, etc.)

For users in the European Economic Area (EEA), the UK, and other applicable regions, a consent dialog is shown on first launch via Google's User Messaging Platform (UMP). You can change your choices anytime under Settings → Manage privacy options in the App.

6. Your Choices (Opt-Out)

Turn off the Settings → Usage data collection toggle to stop usage-analytics and crash-diagnostics collection.
Use Settings → Manage privacy options to revisit advertising consent.
Reset your advertising identifier or limit ad personalization in your device settings.

7. Children's Privacy

The App is not directed to children under 14 and does not knowingly collect their personal information.

8. Data Security

Data stored on your device is protected by the operating system's app sandbox. However, no method of transmission over the internet is completely secure.

9. Changes to This Policy

We may update this policy to reflect legal or service changes, and will post updates on this page.
