Privacy Policy

Effective date: May 24, 2026

This Privacy Policy explains how LifeCraftLab(“we”, “our”, “us”) collects, uses, and protects information when you use our mobile applications and websites, including Nibble (package com.kstudio39.nibble) and any related services (collectively, the “Services”).

We designed our Services to collect as little personal data as possible. Most data created by the app stays on your device.

1. Information we collect

1.1 Information stored locally on your device

The following data is created and stored on your device only. It is not transmitted to our servers:

  • Profile inputs: age, gender, height, weight, activity level and calorie goal. Used to compute your BMR / TDEE locally.
  • Diary entries: the foods, portions and meals you log.
  • Weight log: any weight measurements you record over time.
  • Custom foods: any dishes you create yourself.
  • App preferences: language, theme, photo-analysis quota counter.

1.2 Information processed by third-party AI when you use photo analysis

Nibble offers an optional “Analyze photo” feature. When you take or upload a photo for analysis, the image is sent to Google's Gemini API for the sole purpose of identifying the dish and estimating its macronutrients. We do not store this image on our servers; Google processes it according to Google's Gemini API Additional Terms of Service and the Google Privacy Policy.

Photo analysis is opt-in: nothing is sent to any third party unless you explicitly tap the analyze button.

1.3 Information collected by advertising

Nibble is supported by ads served through Google AdMob. AdMob may collect a limited set of data (such as advertising identifier, IP address, ad interaction events, and device characteristics) to deliver and measure ads. This data is controlled by Google. See Google's How Google uses information from sites or apps that use our services and the AdMob privacy and security information.

You can reset or limit ad personalization at any time from your device: Settings → Google → Ads.

1.4 Optional account (Google Sign-In)

If you choose to sign in with Google, we receive your Google account email and basic profile (name, profile picture URL) solely to identify your account and, in a future release, to sync your data across devices. Sign-in is optional; the app is fully usable without an account.

1.5 Permissions requested by the app

  • Camera — only when you tap the photo-analysis button.
  • Photos / Media — only to let you pick an image for analysis.
  • Internet — to call the Gemini AI service (only when you use photo analysis) and to serve ads.

2. How we use information

  • Provide the core functionality of the app (calorie tracking, history, trends).
  • Compute personalised calorie and macro targets on-device.
  • Identify dishes from photos via the Gemini API when you opt in.
  • Display ads through Google AdMob to fund development.
  • Diagnose crashes and fix bugs (we may use anonymous error logs from Google Play Console).

We do not sell your data. We do not share your diary, weight log, or profile with advertisers or other third parties.

3. Children's privacy

The Services are intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us at contact@lifecraftlab.cc and we will delete the data.

4. Data retention

Data stored locally remains on your device until you delete the data from the app or uninstall the app.

If you signed in with Google, your account record (email + display name) is kept until you request deletion via /policy/data-deletion or revoke access in your Google Account settings.

5. Your rights

Depending on your jurisdiction, you may have the right to:

  • Access the personal data we hold about you.
  • Request correction of inaccurate data.
  • Request deletion of your data (see Data Deletion).
  • Object to or restrict certain processing.
  • Withdraw consent at any time (e.g., stop using photo analysis or sign out).

To exercise these rights, email contact@lifecraftlab.cc.

6. Security

We use industry-standard technical and organisational measures to protect data in transit (HTTPS) and at rest. No system can be 100% secure; we cannot guarantee absolute security, but we work to minimise risk and notify users of material incidents where required by law.

7. International transfers

When you use photo analysis or ads, your data may be processed by Google on infrastructure outside your country. Google is responsible for compliance with applicable data-transfer laws in those cases.

8. Third-party services we rely on

  • Google Gemini API — optional photo analysis (privacy).
  • Google AdMob — advertising (privacy).
  • Google Sign-In — optional account (privacy).
  • Google Play Services — install integrity, crash reporting (privacy).

9. Changes to this policy

We may update this policy from time to time. We will update the “Effective date” at the top of this page and, when changes are material, notify you in-app.
