Effective and last updated: November 13, 2026
This policy explains how SunMarc App Labs handles information in Warranty Vault for Android (package com.sunmarcs.apps.warrantyvault). For information about visiting this website, see our website privacy policy.
At a glance
- No Warranty Vault account or sign-up is required.
- Your receipts, documents and warranty records are stored on your device. Receipt scanning and text recognition happen on-device; the app does not upload their contents to SunMarc or Google for recognition.
- The free app uses Google AdMob. Advertising and supporting Google services process certain device, interaction and diagnostic data separately from your receipt contents.
- Every app feature is free. An optional one-time Google Play purchase removes ads; there is no subscription.
Receipt and warranty information stored on your device
Warranty Vault stores the information you add or confirm so it can organize your purchases and remind you about deadlines. This can include receipt photos and PDFs, warranty cards, product photos, recognized receipt text, product and store names, purchase dates and prices, serial numbers, categories, notes, the location of a paper receipt, warranty and return dates, reminder preferences, and app settings.
This information is used locally to fill in receipt details, search and organize your records, show warranty status, schedule reminders, and prepare the backups, exports or shares you request. SunMarc does not operate an account or cloud-storage service for these records and does not receive them automatically.
Scanning and text recognition
The app uses Google ML Kit document-scanning and text-recognition components. Receipt images, recognized text and recognition results are processed on-device, not sent to Google servers for recognition.
These components can contact Google for downloads or updates and send technical information, such as device and app information, installation identifiers, feature-use events, errors and performance metrics, for diagnostics, usage analytics and service maintenance. This is distinct from uploading your receipt contents. Google describes this processing in its ML Kit privacy information and Android data disclosures.
Backups, exports and sharing you choose
You can create a backup file, restore one on another device, export your list as a spreadsheet, or share selected details and documents. These actions can include personal or financial information contained in your receipts.
You choose where files are saved and which app or recipient receives them. If you select email, cloud storage or another service, that service handles the copy under its own terms and privacy policy. This is a user-initiated transfer, not an automatic upload to SunMarc. Keep exported files and backups secure; deleting a record from Warranty Vault does not delete copies you have saved or shared elsewhere.
Device features and permissions
- Scanning and selected files: the scanner and Android photo/file selection flows let you capture or choose documents you want to add. Selecting an invoice from another app does not give Warranty Vault access to your email account.
- Notifications: notification permission lets the app show the warranty and return reminders you enable. Background scheduling, restart handling and vibration support those reminders. You can change notification permission in Android settings.
- Internet and network state: used for ads, Google service components and updates, and Google Play purchases; receipt recognition itself is on-device.
- Advertising identifiers: used by Google advertising services as described below. The app does not need precise GPS location for receipt or warranty tracking.
- Google Play Billing: used if you choose to purchase or restore the ad-removal upgrade.
Advertising and data processed by Google AdMob
The free app displays ads using Google AdMob. The Google Mobile Ads SDK collects and shares data with Google for advertising, measurement and analytics, and fraud prevention, security and compliance. The app's Google Play Data Safety disclosures cover these categories:
- Approximate location: the device IP address can be used to estimate a general location.
- App interactions: information about app and ad interactions, such as launches, taps and ad views.
- Diagnostics: information about app or SDK performance, errors and reliability.
- Device or other identifiers: identifiers such as the Android Advertising ID and app-set or installation identifiers.
Google encrypts this SDK data in transit. Receipt images, receipt text and your warranty records are not supplied to AdMob by Warranty Vault. SunMarc does not sell your receipt or warranty records.
You can manage the advertising ID and available ad-privacy controls in Android settings. Where a consent or privacy-choice message is presented, use the choices provided there. Available controls depend on your device and region; limiting ad personalization does not necessarily stop all diagnostic or fraud-prevention processing.
For details, see Google Mobile Ads data disclosures and Google's Privacy Policy.
Optional Pro purchase
Warranty Vault Pro is an optional one-time purchase that removes ads, not a subscription or a requirement to use receipt, warranty or reminder features. Google Play processes the purchase and supplies purchase-status information so the app can recognize your entitlement. SunMarc does not receive your payment card details. Removing ads does not disable Google Play's purchase processing or the technical processing needed by other Google components described above.
Retention, deletion and security
Your local records remain on your device until you remove them or clear the app's storage. You can erase the app's local data through Android Settings, or uninstall the app. This does not erase original photos or PDFs outside the app, exported spreadsheets, backup files or copies already shared with others; delete those separately at their saved locations.
SunMarc has no server copy of your receipt library to retrieve or delete, and no Warranty Vault account to close. The app does not provide a server-side deletion-request tool for data processed by Google services. Google's retention and deletion practices and your Google or device privacy controls apply to that data; clearing local app storage does not necessarily delete it.
Use a device lock and protect your backup and shared files. Transmission encryption for Google SDK data does not mean that every local file, backup or export is encrypted by Warranty Vault.
When you contact us
If you email SunMarc for support or a privacy question, we receive the email address, message and attachments you choose to send. We use that information to answer and handle your request and retain it as needed for that purpose and any applicable obligations. Avoid sending complete receipts or other sensitive documents unless they are necessary for your request.
Age suitability
Warranty Vault is intended for users aged 13 and over, not children under 13. Applicable regional Google Play age ratings may be higher. If you believe a child has sent personal information to SunMarc, contact us so we can review and address it.
Changes to this policy
We may update this policy when the app or its data practices change. The date at the top identifies the current version.
