Privacy Policy

01 Introduction

This Privacy Policy describes how eMviasoft Ltd ("we", "us", or "our") collects, uses, and protects information when you use the Guesthouse Butler mobile application (the "App"). By downloading, installing, or using the App, you agree to the practices described in this policy.

Data Controller: eMviasoft Ltd, registered at 2A Frederic Joliot-Curie blvd. 1113 Sofia Bulgaria, Bulgaria. VAT/Company Number: BG207392577. Contact email: info@guesthousebutler.com

We are committed to protecting your privacy and complying with the General Data Protection Regulation (Regulation (EU) 2016/679, "GDPR") and other applicable data protection laws.

02 Privacy-First Design — Local Storage Only

Guesthouse Butler is designed with privacy as a core principle. The App operates primarily as a local-only application:

• All property, reservation, guest, account, and operational data you enter is stored locally on your device using an encrypted SQLite database.
• Your property, reservation, guest, account, and operational data is not transmitted to our servers or third-party servers. Limited analytics data described in Section 5.1 may be transmitted automatically to Google Firebase Analytics.
• We do not have access to the content of your locally stored property, reservation, guest, account, or operational data.
• If you uninstall the App, all locally stored data is permanently deleted from your device.

This means that eMviasoft Ltd does not collect, store, or process the content of your personal property-management data on its servers. The limited analytics data described below is separate from the operational content you create in the App.

03 Information You Provide and Store Locally

When using the App, you may enter the following information, which is stored exclusively on your device:

3.1 Account Information

• Name
• Email address
• Phone number
• Password (stored as a hashed value, never in plain text)

3.2 Property Information

• Property names, addresses, and descriptions
• Property characteristics (rooms, amenities, capacity)
• Photos of properties (if you choose to add them)

3.3 Reservation Information

• Guest names and contact details (entered by you)
• Check-in and check-out dates
• Pricing and payment status
• Reservation notes

3.4 Operational Data

• Stock and consumables tracking (towels, linen, supplies)
• Expense records and financial data
• Cleaning and maintenance schedules

Important: You are solely responsible for the accuracy and lawfulness of any guest data you enter. You must obtain consent from your guests before storing their personal information in the App, in accordance with applicable privacy laws.

04 Device Permissions

The App requires the following permissions on your device:

4.1 Notifications

The App requests permission to send local notifications to remind you about upcoming reservations, cleaning schedules, and stock alerts. These notifications are generated locally on your device and are not sent through our servers. You can disable notifications at any time in your device settings.

4.2 Photo Library / Camera Access

If you choose to add photos to property listings, the App requires access to your photo library or camera. Photos are stored locally on your device and are never uploaded to our servers.

4.3 Local Storage

The App stores its database file locally on your device. This is necessary for the core functionality of the App.

05 Data Transmission and Third Parties

We do not transmit your property, reservation, guest, account, or operational data over the internet. The App does not include cloud synchronization, online backup, or any feature that uploads such content to remote servers. The App does, however, use Firebase Analytics for the limited analytics purposes described below.

Network communication may occur for the following limited purposes:

• Subscription payment processing through the official app store (Apple App Store or Google Play Store), which is governed by their respective privacy policies.
• Analytics processing through Google Firebase Analytics, as described in Section 5.1.

5.1 Firebase Analytics

The App uses Google Firebase Analytics to understand how the App is used and to improve its functionality, reliability, and user experience. Firebase Analytics may automatically collect the following limited data categories:

• Identifiers — Device ID (Firebase App Instance ID). Purpose: Analytics. Linked to the user: No.
• Usage Data — Product Interaction. Purpose: Analytics.

The Firebase App Instance ID is a randomly generated app-installation identifier used for analytics. It is not your hardware serial number, advertising identifier, name, email address, or account identifier, and eMviasoft Ltd does not use it to identify you personally.

Product Interaction data may include information about screens viewed, features used, in-app actions, session activity, and similar interactions with the App. It does not include the content of your property records, reservation records, guest details, photos, expenses, passwords, or other operational data stored locally on your device.

We use this analytics data only to measure product usage, diagnose usability issues, improve features, and maintain the App. We do not use it for advertising, personalised advertising, marketing profiles, or the sale of personal data.

Firebase Analytics is provided by Google. Google may process analytics data in accordance with its own privacy terms and applicable data-protection safeguards.

06 Subscription and Payment Information

Subscription purchases are processed exclusively through the Apple App Store or Google Play Store. We do not collect or store payment card details. The app stores receive and process all payment information according to their own privacy policies:

• Apple App Store: www.apple.com/legal/privacy
• Google Play Store: policies.google.com/privacy

Your free-trial status is stored locally on your device only and is not transmitted to us or any third party.

We may receive limited subscription status information from the app stores (e.g., active/inactive subscription) to verify your access to premium features.

07 Legal Basis for Processing (GDPR)

To the extent that any processing of personal data occurs, the legal basis is:

• Performance of a contract — to provide the App and its features to you (Article 6(1)(b) GDPR).
• Legitimate interest — to maintain and improve the App, prevent fraud, and ensure security (Article 6(1)(f) GDPR).
• Consent — for any optional features you explicitly enable (Article 6(1)(a) GDPR).
• Legal obligation — to comply with applicable laws (Article 6(1)(c) GDPR).

08 Your Rights Under GDPR

Since your data is stored locally on your device, you have full and direct control over it at all times. Additionally, under GDPR you have the following rights:

• Right of access — request a copy of any personal data we may hold about you.
• Right to rectification — correct inaccurate or incomplete data.
• Right to erasure ("right to be forgotten") — request deletion of your data; you can do this directly by uninstalling the App or clearing app data.
• Right to restrict processing — limit how your data is processed.
• Right to data portability — receive your data in a structured, machine-readable format.
• Right to object — object to processing based on legitimate interest.
• Right to withdraw consent — at any time, where processing is based on consent.
• Right to lodge a complaint — with the Bulgarian Commission for Personal Data Protection (CPDP) or your local supervisory authority.

To exercise any of these rights, contact us at info@guesthousebutler.com.

09 Children's Privacy

The App is not intended for use by individuals under the age of 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal information, please contact us immediately and we will take steps to delete it.

10 Data Security

We take reasonable technical and organizational measures to protect data within the App:

• Passwords are stored as cryptographic hashes (never in plain text).
• The local database is protected by your device's operating system security.
• We recommend using device-level security (PIN, biometrics, encryption).

However, no method of electronic storage is 100% secure. You are responsible for protecting your device and login credentials.

11 Data Retention

Data is retained on your device for as long as you keep the App installed. To delete all data:

• Uninstall the App from your device, or
• Use the device settings to clear app data, or
• Use the in-app option to delete your account (if available).

Firebase Analytics data is retained in accordance with the retention settings configured for the Firebase project and Google's applicable retention practices. Because analytics identifiers are not linked by us to your identity, we may not be able to associate an analytics record with a particular individual based solely on a privacy request.

12 International Data Transfers

No international transfer of your locally stored property, reservation, guest, account, or operational data occurs as part of the App's core functionality. Limited Firebase Analytics data and data processed by Apple, Google, or other app-store service providers may be transferred and processed in other countries under their respective privacy frameworks and safeguards.

13 Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Material changes will be communicated through the App. We encourage you to review this policy periodically.
