Delete Your Data

How to erase your personal data from Alcophone

Your Personal Data Lives on Your Device

Alcophone is built privacy-first. Your drink history, body measurements, preferences, achievements and BAC calculations are stored only on your device and are never sent to any server. We do not run user accounts.

This means you are always in full control, and deleting it is instant and complete.

How to Delete All Your Data

From within the app:

  1. Open Alcophone
  2. Tap the Settings tab
  3. Scroll down to Privacy & Legal
  4. Tap “Erase All Data”
  5. Confirm when prompted (two-step confirmation)

What Gets Deleted

  • All drink history and BAC calculations
  • Personal profile (age, weight, height, body measurements)
  • Preferences and settings
  • Achievement progress
  • Calorie tracking data
  • All cached data

What About Analytics & Crash Reports?

If you have left analytics or crash reporting enabled, the app sends Google (via Firebase) a small amount of pseudonymous usage data. This is important to understand:

  • It is not linked to your identity. Alcophone never collects your name, email, or any contact details, so this data is tied only to a random app identifier — not to your name or contact details. There is no “account” for us to look up, and no email-based request can match the data back to you, because no such link exists.
  • You can stop it at any time. Go to Settings > Privacy & Legal and turn off the Analytics and Crash Reporting toggles. Once off, nothing further is collected or transmitted.
  • It is deleted automatically. User-level analytics data is deleted by Google after at most 14 months, and crash data after 90 days. Erasing your data or reinstalling the app generates a new analytics identifier, disconnecting future data from past activity.
  • The trial record holds no name or contact details. If you started a free trial, a random identifier and your trial dates are stored on Google Cloud so that the free trial can be used only once. It has no automatic expiry, and erasing your data does not delete it.

In short: there is no personal profile of you on any server. The only place your real, identifiable data exists is on your own device — and the steps above erase it completely.

What Is NOT Affected

  • Premium purchase — Your purchase is tied to your Google Play account, not the app. You can restore it anytime.
  • Analytics opt-in/out — If you opted out of crash reporting or analytics, that choice is preserved.
  • The trial record — a random identifier and your trial dates on Google Cloud, kept so that the free trial can be used once (see the Privacy Policy, Section 6).
  • Analytics and crash data already sent — erasing resets the analytics identifier, so new data is not connected to the old.

This action is permanent

Once erased, your on-device data cannot be recovered. Since your drink log and profile are stored only on your device, there is no server backup to restore from. The app will return to its initial setup screen.

Alternative: Uninstall

Uninstalling Alcophone from your device also removes all locally stored data. The result is the same as using the in-app erase function.

Questions?
