Privacy Policy

Rvira LLC & Appcent LLC  ·  Effective Date: January 1, 2024  ·  Last Updated: June 18, 2026

This Privacy Policy describes how Rvira LLC and its affiliated publishing entity Appcent LLC (collectively, "we," "us," or "our") collect, use, and share personal information when you use our website, mobile applications, and related services (collectively, the "Services"). This policy applies to all applications published by Appcent LLC on the Apple App Store and Google Play Store, as well as the Rvira LLC website at rvira.us. Please read this policy carefully.

1. Information We Collect

1.1 Information You Provide

We collect information you voluntarily provide when you contact us, request a quote, or use our Services:

  • Contact Information: Name, email address, phone number, company name, and postal address.
  • Project Information: Details about your app development project, budget, and requirements.
  • Account Information: If you create an account, username and password (hashed).
  • Communications: Messages, emails, and other communications you send us.
  • Payment Information: Billing details processed securely through third-party payment processors (we do not store raw card data).

1.2 Information Collected Automatically

When you use our Services, we may automatically collect:

  • Device Information: Device type, operating system, unique device identifiers, and hardware model.
  • Usage Data: Pages visited, features used, time spent, click data, and navigation paths.
  • Log Data: IP address, browser type, referring URL, and crash reports.
  • Location Data: General geographic location based on IP address (not precise GPS unless explicitly granted).
  • Cookies & Tracking: Cookies, pixel tags, and similar technologies as described in our Cookie Notice.

1.3 Information from Third Parties

We may receive information about you from third-party sources such as analytics providers, advertising partners, and social media platforms, which we combine with information we have collected directly.

1.4 Data We Do Not Collect or Store

Transparency matters to us. Some of our apps may access certain device sensors, permissions, or data solely to provide a feature in real time. Where this is the case, the data is processed on your device only, used momentarily to deliver the functionality, and is never collected, transmitted to our servers, stored, sold, or shared with any third party. The following describes data we do not collect or retain:

  • Face Data & Biometric Data: Certain features (such as face-based interactions, AR effects, TrueDepth/face-detection experiences, avatars, or camera filters) may process facial geometry, face landmarks, or camera imagery entirely on your device. We do not collect, store, upload, log, or share face data or any other biometric identifiers. No facial recognition data is used to identify you, and nothing is retained after the feature is used.
  • Camera & Photos: When an app uses the camera or accesses photos for a feature (e.g., scanning, image processing, or previews), the images are processed on-device for that purpose only. We do not upload or store your camera feed or photo library unless you explicitly choose to submit specific content to us.
  • Precise Location (Environmental Features): Features such as UV Index, weather, air quality, sunrise/sunset, or nearby information may use your device location to fetch relevant real-time data. This location is used only to retrieve that information for you and is not stored, tracked, profiled, or associated with your identity on our servers.
  • Health & Motion Sensors: Where an app reads sensors such as the accelerometer, gyroscope, barometer, pedometer, or health metrics to power a feature, this data is used locally in real time and is not collected or retained by us.
  • Microphone & Audio: If a feature uses the microphone (e.g., sound level, voice input, or noise measurement), audio is processed on-device for that function only and is not recorded, stored, or transmitted to us unless you explicitly submit it.
  • Contacts, Calendar & On-Device Content: If an app requests access to contacts, calendar, or files to enable a convenience feature, that information stays on your device and is not uploaded to our servers.

In short: when an app accesses a sensor or permission purely to show you information or power a feature (like the UV index, weather, AR effects, or on-device scanning), that access is functional and temporary. We are not collecting, storing, or monetizing that data. Any permission we request is limited to what is necessary for the feature to work, and you can revoke permissions at any time in your device settings. Where an app's specific behavior differs, that app's in-app disclosures and App Store / Google Play privacy labels govern.

2. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and improve our Services and mobile/web applications.
  • Respond to your inquiries, quotes, and support requests.

8a. Account Deletion (App Store & Google Play)

As required by Apple App Store Review Guideline §5.1.1(v) and Google Play's Account Deletion Policy, users of apps published by Appcent LLC can request deletion of their account and associated personal data at any time. We provide two equivalent paths:

  • In-App: Open the app, go to Settings → Account → Delete Account, and confirm. Deletion is processed within 30 days.
  • Via Website / Email: Send a deletion request to i@rvira.us from the email associated with your account. Include the app name and your account identifier. We confirm receipt within 72 hours and complete deletion within 30 days.

Upon deletion, we remove or anonymize: profile data, user-generated content, authentication credentials, in-app preferences, and analytics linked to your identifier. Data we are legally required to retain (e.g., tax records, fraud-prevention logs) is retained only for the minimum period required by law and remains protected. Deletion of your account does not entitle you to refunds of any prior purchases; refunds are governed by Apple's and Google's respective refund policies.

8b. Third-Party SDKs & Service Providers

Our apps published by Appcent LLC may incorporate the following categories of third-party SDKs and services. We disclose all such SDKs accurately in Apple's Privacy Nutrition Labels and Google Play's Data Safety form:

  • Analytics: Firebase Analytics, Google Analytics for Firebase, Apple App Analytics — used to understand usage patterns, crashes, and performance. Data collected includes device identifiers, app interactions, and approximate location.

8c. Advertising Identifiers & Ads

For apps that display advertising or measure ad performance, our use of advertising identifiers complies with both platforms' requirements:

  • Apple IDFA (Identifier for Advertisers): We request access only via Apple's App Tracking Transparency (ATT) framework. We honor the user's response and do not track across apps or websites owned by other companies without explicit ATT permission.
  • Google Advertising ID (GAID) / Google Play Services Advertising ID: We comply with Google Play's Advertising ID policy. Users may reset or delete their Advertising ID via Android system settings, and we respect that choice. We do not connect persistent device identifiers to Advertising IDs for purposes that violate Google's policies.
  • Children's Apps: Apps targeting children or designed for mixed audiences under Google Play's Families Policy and Apple's Kids Category do not collect advertising identifiers or display third-party behavioral advertising.
  • Opt-Out: You may opt out of personalized advertising at any time via your device settings (iOS: Settings → Privacy & Security → Apple Advertising; Android: Settings → Google → Ads).

8d. In-App Purchases & Subscriptions

Where our apps offer in-app purchases or auto-renewing subscriptions, all transactions are processed exclusively through Apple's In-App Purchase system or Google Play Billing in accordance with each platform's policies:

  • Disclosure: Subscription length, price, auto-renewal behavior, and free-trial terms are disclosed clearly before purchase.
  • Auto-Renewal: Subscriptions automatically renew at the price disclosed unless canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions any time in your App Store account settings (iOS) or Google Play subscriptions (Android).
