Privacy Policy

Last Updated & Effective Date: November 07, 2026

1. Introduction & Overview

Welcome to WatchFul AI Tech ("Company", "We", "Us", or "Our"). We operate the primary website watchfulaitech.com, in-house consumer mobile applications (including OS Calculator - Convertor, Sheet Expense Tracker - Finance, and related mobile software), enterprise client engineering projects, and the WatchFul Ads Platform operating at ads.watchfulaitech.com (collectively, the "Services").

We take privacy seriously and are committed to transparency. This Privacy Policy details the types of information we collect, how it is processed and protected, and your rights regarding your personal data in accordance with Google Play Developer Policies, GDPR, and global data privacy standards.

2. Offline-First & Privacy-Focused Consumer Apps

Our Privacy Guarantee: Flagship consumer utility applications (such as Sheet Expense Tracker) are built with an Offline-First architecture. Your personal financial ledger entries and confidential notes are stored strictly on your local device using encrypted SQLite/Room database storage and are never uploaded to any remote server without your explicit consent.

For consumer utility apps that do not require cloud accounts, you can use core functionality with complete anonymity. We do not sell, rent, or trade your personal information to third parties.

3. Information We Collect

A. Technical & Diagnostic Telemetry

To ensure our benchmark 0.01% crash rate and deliver reliable software performance across Android versions (including Android 12, 13, 14, and above), we may process anonymous diagnostic logs via industry standard SDKs (e.g., Firebase Crashlytics):

  • Device model, manufacturer, and operating system build.
  • Application version and bundle ID.
  • Non-identifiable stack traces and memory state at the moment of an unexpected crash or Application Not Responding (ANR) incident.

B. WatchFul Ads Platform (ads.watchfulaitech.com) & Advertising Data

When accessing applications or publisher inventory served by the WatchFul Ads Platform, non-personally identifiable advertising metadata may be processed to deliver appropriate ads, combat click fraud, and calculate accurate developer yield:

  • Google Advertising ID (GAID) or device ad identifiers (subject to your operating system permissions and opt-out preferences).
  • IP address (anonymized/truncated for geographic country-level ad delivery).
  • Ad impressions, click verification tokens, and aggregated completion rates.

C. Information You Voluntarily Provide

If you contact us via email, submit an inquiry through our client contact form on watchfulaitech.com, or request technical support, we collect the details you supply (e.g. your name, email address, company name, and project specifications) strictly to respond to your request.

4. Purpose & Legal Basis for Processing

We process data for the following lawful purposes:

  • Service Execution: Delivering requested app features, calculation results, and offline financial tracking.
  • Stability & Maintenance: Debugging native crashes, fixing ANRs, and optimizing rendering speed.
  • Monetization & Mediation: Serving contextual advertisements through the WatchFul Ads Platform and managing Google Play In-App Billing (IAP) subscriptions.
  • Compliance & Safety: Adhering to applicable regulatory standards, Google Play Store requirements, and preventing abuse.

5. Third-Party Integrations & SDKs

Depending on which app or service you access, the following vetted third-party services may process technical data in compliance with their independent privacy policies:

  • Google Play Services & Google Play Billing: For secure in-app purchases and app distribution.
  • Google AdMob & Programmatic Ad Partners: For in-app ad monetization.
  • Firebase (Crashlytics, Analytics, Cloud Messaging): For real-time stability monitoring and targeted operational push notifications.
  • Cloudflare: For edge network routing, SSL/TLS encryption, and web DDoS mitigation on watchfulaitech.com.

6. Children’s Privacy (COPPA Compliance)

Our services and consumer applications are designed for general audiences and do not knowingly collect personal identifiable information from children under 13 years of age. If you believe that a minor has provided us with personal information without parental consent, please contact us immediately, and we will delete such data from our records promptly.

7. Data Retention & Security Standards

We employ industry-standard administrative, technical, and physical measures to protect your data. All web communication with watchfulaitech.com and ads.watchfulaitech.com is enforced with HTTPS and TLS 1.3 encryption. Diagnostic crash logs are automatically purged on rolling 90-day cycles.

8. Your Rights & Choices

Depending on your geographic location (e.g., GDPR in the EU/EEA, CCPA in California), you have rights regarding your personal information:

  • The right to access, rectify, or request deletion of any personal data we hold.
  • The right to opt-out of personalized advertising by resetting your Google Advertising ID in your Android Device Settings (Settings > Google > Ads > Delete advertising ID).
  • The right to withdraw consent for diagnostic telemetry at any time.
