Privacy Policy

1. Overview & Who We Are

MyStuff POS ("we", "our", "us") is a point of sale application for Android devices developed by MyStuff POS. This Privacy Policy explains how we collect, use, and protect information when you use our mobile application ("App") and our website at mystuffpos.app ("Website").

By using the App or Website, you agree to the practices described in this Privacy Policy. If you do not agree, please discontinue use of the App and/or Website.

This Privacy Policy applies to:

• The MyStuff POS Android application
• The MyStuff POS website (mystuffpos.app)
• Any updates or new versions of the above

2. Information We Collect

We collect minimal information, and most of your business data never leaves your device. Below is a breakdown:

2.1 Information Collected Automatically (via Ad Network)

• Advertising ID: A resettable device identifier used by Google AdMob to serve relevant ads. You can reset or opt out of this at any time in your device settings.
• Device information: Device model, Android version, screen size, and language settings — used for ad rendering and compatibility.
• IP address: Used to determine approximate country-level location for ad targeting (not precise location).
• App usage signals: Ad impression and click events logged by AdMob to measure ad performance.

2.2 Analytics Data (via Firebase/Google Analytics for Firebase, if enabled)

• Crash reports and error logs to help us fix bugs.
• Anonymous app usage data (screen views, feature usage frequency) to guide product improvements.
• No personally identifiable information is included in analytics events.

2.3 Information You Provide

If you contact us via email or the Play Store review system, we receive your email address and any information you choose to share. This is used solely to respond to your inquiry.

3. Data Stored on Your Device

The core business data in MyStuff POS is stored exclusively on your Android device in a local SQLite database. This includes:

• Business name, currency, and configuration settings
• Staff/employee profiles and PINs (stored locally)
• Product inventory — items, variants, categories, stock levels, prices
• Sales records and transaction history
• Customer directory (names, contact details, tax numbers)
• Invoices, quotations, and delivery notes
• Payment methods and payment records
• Backup files (stored on device storage or external storage you control)

When you use the multi-device sync feature, data is transmitted directly between your own devices via a local peer-to-peer connection (Bluetooth or Wi-Fi Direct). This data does not pass through our servers or any cloud service.

4. Advertising

MyStuff POS is free to use. To support the development and maintenance of the app, we display ads provided by Google AdMob (a service of Google LLC).

Google AdMob may collect and use data in accordance with Google's Privacy Policy, including:

• Advertising ID to serve personalized ads (unless you opt out)
• General device and network information
• Interaction data (ad clicks and impressions)

Opting Out of Personalized Ads

You can opt out of personalized advertising at any time:

• Go to your Android device Settings → Privacy → Ads
• Select "Opt out of Ads Personalization" or "Delete Advertising ID"

You will still see ads, but they will not be personalized based on your interests.

5. App Permissions

MyStuff POS requests the following Android permissions and uses them only for the stated purposes:

Storage

• Read/Write External Storage: To save and restore database backup files to/from your device storage. We do not read any other files on your device.

Connectivity

• Bluetooth & Bluetooth Admin: Required for connecting to Bluetooth thermal receipt printers and for the nearby device sync feature.
• Wi-Fi State & Access Wi-Fi State: Required for the peer-to-peer multi-device data sync feature (Wi-Fi Direct / Nearby Connections).
• Internet: Required solely for loading advertisements (AdMob). Your business data does not use this permission.
• Nearby Devices (Android 12+): Required to discover and connect to nearby devices for sync.

Other

• Vibrate: For haptic feedback on button presses (optional UX enhancement).
• Wake Lock: To prevent the screen from sleeping during an active sales session.

6. Third-Party Services

We use the following third-party SDKs and services. Each has their own privacy practices:

Google AdMob

Provides in-app advertising. Collects advertising ID and device information for ad serving. Privacy Policy

Google Play Services

Required for the Android platform and used for app distribution. Privacy Policy

Google Nearby Connections API

Used for the multi-device sync feature to discover and connect nearby Android devices over Bluetooth/Wi-Fi. Data transmitted through this API is your business data and travels device-to-device only. Privacy Policy

Firebase Crashlytics (if enabled)

Collects anonymized crash reports to help us identify and fix bugs. No personal or business data is included in crash reports. Privacy Policy

7. How We Share Information

We do not sell, rent, or trade your information to third parties. We may share limited, non-personal information in the following circumstances:

• Service providers: Third-party SDKs (AdMob, Firebase) as described above, solely to operate the app.
• Legal compliance: If required by law, court order, or governmental authority.
• Business transfer: In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction, subject to the same privacy protections.
• With your consent: In any other circumstance, only with your explicit permission.

8. Data Retention

Since your business data is stored on your device, you control its retention. You can delete the app at any time, which will remove all locally stored data.

For data collected by third-party services (AdMob analytics, crash reports), data is retained per those services' policies, typically 14 to 63 months.

If you contact us by email, we retain your correspondence for as long as necessary to resolve your issue, and no longer than 2 years.

9. Children's Privacy

MyStuff POS is a business application designed for use by adults and businesses. It is not directed at children under the age of 13 (or the applicable age of digital consent in your jurisdiction).

We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us immediately at privacy@mystuffpos.app and we will take steps to delete such information.
