Summary. Nailva stores customer data locally on your device by default. If you opt into Cloud Backup or use OAuth login, certain data is transmitted to our servers. Anonymous diagnostics, crash logs, and an advertising ID are collected to operate, improve, and monetize the app.
The table below corresponds to the Google Play Data Safety declaration for this app.
2.1 Stored Only on Your Device (Not Collected)
The following data is entered by you and stored in a local SQLite database on your device. It is not transmitted to our servers unless you enable Cloud Backup (Section 2.2).
Customer names, phone numbers, notes
Service records and photos
Booking information
Revenue and statistics
App settings (language, theme)
2.2 Cloud Backup (Optional, Opt-In)
If you sign in via Settings β Cloud Backup using Google or Kakao OAuth, the following data is transmitted to and stored on our Nailoop backup server:
Email address, nickname, social account identifier (Google ID / Kakao ID)
You can stop the transmission at any time by signing out of Cloud Backup. To delete the data already on the server, see Section 5.

4. Data Sharing with Third Parties
We do not sell your personal information. The only third party that uses your data for its own purposes is Google (AdMob), which uses your advertising ID to serve ads. All other third-party services (Firebase, PostHog, Sentry) act as data processors under a data processing agreement and process data only on our behalf.
5. Data Retention and Deletion
Local data: stored until you delete it in-app or uninstall the app.
Cloud Backup server data: retained until you request deletion via email. See the Account Deletion Guide.
Sentry crash logs: auto-expire after 90 days.
PostHog analytics: auto-expire after 7 days.
Firebase Analytics & Crashlytics: retention per Google's policy.
Anonymized aggregate statistics: may be retained indefinitely in non-identifiable form.
Local data is stored in the app's private sandbox on your device.
Server data is access-controlled and stored on infrastructure operated by Info-Gate.
