CertArch Privacy Policy
CertArch ("we", "our", "the app") is an exam-preparation app for the AWS Certified Solutions Architect – Associate (SAA-C03) certification. This Privacy Policy explains what information CertArch collects, how it is used, and the choices you have. By using CertArch, you agree to the collection and use of information as described here.
Information We Collect
CertArch uses Google Firebase to provide its core features. Firebase collects and processes the following categories of data on our behalf:
| Category | What it includes | Purpose |
|---|---|---|
| Account identifiers | An anonymous device-linked user ID (Firebase Authentication). If you choose to sign in with Google, your Google account name and email address. | To identify your account and sync your data across sessions |
| Study activity | Practice answers, mock exam scores, domain-by-domain progress, streaks, and bookmarked questions | To save your progress and show performance analytics |
| Purchase status | Subscription/entitlement status (active, expired) via Google Play Billing. CertArch does not receive or store your payment card details – these are handled entirely by Google Play. | To unlock Premium features you've paid for |
| Usage & diagnostics | App usage events (e.g. screens viewed, features used) via Firebase Analytics, and crash/error reports via Firebase Crashlytics, including device model, OS version, and approximate performance data | To understand feature usage and diagnose and fix crashes/bugs |
How We Use Your Information
- To provide, maintain, and improve the practice questions, mock exams, and progress tracking features
- To sync your progress, bookmarks, and subscription status across app sessions
- To diagnose crashes and technical issues via Firebase Crashlytics
- To understand aggregate feature usage via Firebase Analytics, in order to improve the app
We do not sell your personal information, and we do not use your data for third-party advertising.
Third-Party Services
CertArch relies on the following third-party service providers, each of which processes data under its own privacy policy:
- Google Firebase (Authentication, Firestore database, Analytics, Crashlytics)
- Google Play Billing (subscription purchases)
Data Retention
Your study progress and account data are retained for as long as your account is active. You can request deletion of your account and associated data at any time by contacting us (see below); we will delete your data within a reasonable timeframe, except where retention is required for legal or fraud-prevention purposes (e.g. billing records).
Your Choices
- Delete your data: contact us at the email below to request full deletion of your account and study data.
- Manage your subscription: subscriptions are managed through Google Play – you can cancel anytime via the Play Store's Subscriptions page.
Children's Privacy
CertArch is intended for adults and professionals studying for an AWS certification exam. It is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
Security
Data is stored using Google Firebase's infrastructure, which encrypts data in transit and at rest. While we take reasonable steps to protect your information, no method of transmission or storage is 100% secure.

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page.
