Magic Bytes Soft apps for Android

Last updated: 2 November 2026

This policy covers every Android app published on Google Play by Magic Bytes Soft, the trading name of Alexandru Cebotari in the United Kingdom. "We" means that publisher, who decides how this data is used, and "the app" means whichever of these apps you use. Contact: magic.bytes.soft@gmail.com.

What the app does not ask for

The app has no account or sign-in. It does not ask for your name, email, contacts, photos or precise location, and it shows no ads.

What stays on your phone

Your answers, sessions, bookmarks and settings are stored on your phone. Android's backup may copy your study results and settings to your own Google account backup if you have that switched on. We cannot read that backup.

What is sent from your phone

• How you use the app Screens opened, sessions started, abandoned and finished, answers marked right or wrong by exam domain, time-per-question ranges, features used. Never question text, what you type, or your identity. Why: to see what works and improve the app. Service: Google Analytics for Firebase.
• App-instance and installation identifiers Google uses these to count devices; we do not link them to your name. Why: to count users and keep reports consistent. Service: Firebase.
• Approximate location Roughly city or country, worked out by Google from a masked IP address. Why: to see which regions use the app. Service: Google Analytics for Firebase.
• Purchase events Such as the product and price. Why: to see whether purchases work. Service: Google Analytics for Firebase.
• Crash reports Stack trace, device model, Android version, app state, and a crash installation identifier. Why: to find and fix faults. Service: Firebase Crashlytics.
• Device settings Country, language, time zone, Android version and app version. Why: to deliver app settings. Service: Firebase Remote Config.

Data is encrypted in transit. Google processes it for us under its data processing terms. It may be handled outside the UK and EEA, including in the US, where Google is certified under the EU-US Data Privacy Framework and its UK extension.

Your choice

The app asks before anything goes to Google Analytics. How you use the app, the app-instance identifier, approximate location and purchase events are sent only if you tap Allow. Until you answer, and if you tap No thanks, none of that is sent and the app works the same.

What you do in the app before you answer, such as opening a notice about an exam update, waits on your phone: it is sent if you tap Allow and deleted if you tap No thanks.

You can change your answer at any time under Privacy in the More tab. Turning it off stops collection at once and deletes the analytics data still on your phone; data already sent stays until the retention period below ends.

Crash reports and Remote Config do not depend on this choice. Crash reports are always sent so we can fix faults, and they do not include your name or email. We send them because we have a legitimate interest in keeping the app working for everyone who uses it.

Payments

Purchases are handled by Google Play. We never see your card details. To restore or support a purchase, we may ask for your Google Play order number.

If you email us

We receive your email address and whatever you send, and use them only to answer you. We keep emails for up to 2 years after your last message, then delete them.

Earlier versions of AWS Architect

Older versions of AWS Architect offered optional sign-in with Google and could store your exam progress in Google's Firebase. That data still exists and is linked to your account. The current version does not read it or add to it. We keep it for now and will update this page if that changes. To have yours deleted, email us from the Google account you signed in with.

How long data is kept

• Crash reports: 90 days.
• Analytics event data: 14 months.
• Installation identifiers used by Remote Config: until deleted, then removed within 180 days.
• Study data on your phone: until you reset progress in Settings or uninstall the app.

Your rights

Depending on where you live, you can ask to access, correct or delete your data, or object to its use, and you can complain to your data protection authority (in the UK, the Information Commissioner's Office). Email us. We cannot normally match analytics data to you, because it holds no name or email.

Why we are allowed to use your data:

• Usage analytics: your consent, which you can withdraw at any time under Privacy in the More tab.
• Crash reports and Remote Config: our legitimate interest in keeping the app working and up to date.
• Purchases: to provide what you bought.
• Support emails: our legitimate interest in answering you.

Children

Our apps are for adults aged 18 and over preparing for a professional certification. They are not directed at children, and we do not knowingly collect data from anyone under 18.

Changes

We will update this page and its date when our practices change.
