Privacy Policy

Warranty Wallet · Effective date: 4 October 2026

This Privacy Policy explains how Warranty Wallet (the "App"), operated by Md. Ariful Islam, collects, uses, stores, and protects your information. By using the App you agree to the practices described here.

1. Information We Collect

Account information. When you sign in with Google, we receive your name, email address, profile photo, and a unique account ID from your Google account.

Content you add. Product details you enter: product name, category, brand, model, serial number, purchase price, purchase date, store name, warranty duration, and service records.

Photos and documents. Photos of receipts, warranty cards, and products that you take or select, and claim PDFs you generate in the App.

Receipt scanning. If you use the receipt scanner, text recognition runs on your device using Google ML Kit. The scanned image and text are not sent to us for recognition.

Technical information. Google and Firebase services that the App relies on (sign-in, database, file storage) may automatically process technical data such as IP address, device and app information, and timestamps to deliver the service and protect it from abuse.

Advertising information. The App displays banner and interstitial ads provided by Google AdMob. To serve and measure ads, AdMob may automatically collect and process device and usage data, including your device's advertising ID, IP address, device and operating system information, app interaction data, and approximate location derived from your IP address. We do not receive or control this data, and we do not share your account details, product records, photos, or documents with advertisers.

The App does not use analytics or crash-reporting services, and does not collect your precise location, contacts, or payment card information.

2. How We Use Your Information

To sign you in and identify your account.
To store, display, and organize your products, warranties, and documents.
To back up your data and restore it when you reinstall the App or use a new device.
To send warranty expiry reminders as notifications on your device.
To generate warranty claim documents you request.
To show banner and interstitial advertisements, which help keep the App available.
To secure the service and comply with legal obligations.

We do not sell your personal information. The content you add (products, warranties, photos, documents) is never used for advertising purposes.

3. Where Your Data Is Stored

On your device: a local database and your attached photos, kept in the App's private storage. Removed when you uninstall the App.
Google Firebase (Cloud Firestore and Authentication): your account ID and product/warranty details are backed up to a Firebase project operated by the Service Provider, stored under your account. Access rules restrict each record to the account that owns it.
Your Google Drive: photos and claim PDFs are uploaded to a "Warranty Wallet" folder in your own Google Drive. The App uses the drive.file permission, which only lets it access files the App itself created, not your other Drive content.

4. Google User Data

Warranty Wallet's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is used only to provide the features described in this policy, is not transferred to others except as needed to provide those features, comply with law, or protect security, and is not used for advertising. Data received through Google Sign-In and Google Drive is not used to serve or target ads.

You can revoke the App's access to your Google account at any time at myaccount.google.com/permissions.

5. Permissions the App Requests

Camera: to photograph receipts, warranty cards, and products.
Photos / media: to let you choose existing images.
Notifications: to send warranty expiry reminders.
Internet access: to sign in, back up or restore your data, and load ads.
Advertising ID (Android): used by Google AdMob to serve and measure ads. You can reset or delete your advertising ID, or opt out of personalized ads, in your device settings (see Section 8).

You can change these permissions anytime in your device settings.

6. Sharing of Information

We do not sell, rent, or trade your personal information. We share data only:

With service providers that operate the App's infrastructure (Google, Firebase), who process it on our behalf;
With Google AdMob, which collects certain device and usage data directly in order to serve and measure ads (see Section 8);
When required by law, subpoena, or legal process;
When necessary to protect our rights, your safety or the safety of others, or to investigate fraud.

Claim PDFs and photos leave the App only when you choose to share or print them.

7. Third-Party Services

The App uses these third-party services, which have their own privacy policies:

8. Advertising

The App is supported by advertising. It shows banner ads (displayed within the App's screens) and interstitial ads (full-screen ads shown at natural breaks, such as when moving between screens).

Ads are delivered by Google AdMob. AdMob and its partners may use your device's advertising ID and similar technologies to show ads and measure their performance.
Depending on your region and settings, ads may be personalized or non-personalized. Where required (for example in the EEA, UK, and some other regions), we ask for your consent before showing personalized ads, and you can change your choice at any time.
You can opt out of personalized ads by resetting or deleting your advertising ID in your device settings (on Android: Settings > Privacy > Ads), or by visiting adssettings.google.com.
We do not control the data collected by AdMob. Please review Google's Privacy Policy and How Google uses data when you use partners' sites or apps for details.
Ads do not use the contents of your products, warranties, photos, or documents, or any data obtained through Google Sign-In or Google Drive.

9. Data Retention

We keep your account and backed-up data for as long as your account is active. When you request deletion (see below), we delete your Firestore data and account record within 30 days. Files in your Google Drive "Warranty Wallet" folder belong to you and stay in your Drive until you delete them yourself. Uninstalling the App removes local data from your device but does not delete cloud backups. Data collected by Google AdMob is retained according to Google's own policies.

10. Account and Data Deletion

To delete your account and associated data, email arifewucse2016@gmail.com from the Google account you use with the App, with the subject "Delete my Warranty Wallet data". We will delete your account record and all product, warranty, and document records stored in Firestore within 30 days and confirm by email. To also remove uploaded files, delete the "Warranty Wallet" folder in your Google Drive and revoke the App's access at myaccount.google.com/permissions. To limit advertising data, reset your advertising ID in your device settings.

11. Your Rights

Depending on where you live, you may have the right to access, correct, delete, or export your personal data, to withdraw consent, and to object to or restrict certain processing (including personalized advertising). To exercise any right, contact us at arifewucse2016@gmail.com. We will respond within a reasonable time as required by law. If you are in the European Economic Area or UK, you also have the right to lodge a complaint with your local data protection authority.

Where the GDPR applies, we process your data to provide the service you requested (contract), based on your consent where you grant permissions, sign in, or consent to personalized ads, and for security and fraud-prevention (legitimate interests).

California residents (CCPA/CPRA): you have the right to know what personal information we collect, to request its deletion, and to non-discrimination for exercising your rights. We do not sell personal information for money. However, the use of advertising identifiers by ad partners may be considered "sharing" for cross-context behavioral advertising under California law; you can opt out by resetting your advertising ID or turning off ad personalization in your device settings, or by contacting us.

12. International Data Transfers

Google, Firebase, and AdMob may process and store data on servers in countries other than your own, including the United States. Where required, these providers rely on recognized transfer mechanisms such as Standard Contractual Clauses.

13. Security

Data is transmitted to and from Google and Firebase services over encrypted connections (HTTPS/TLS), and access to your cloud records is restricted to your signed-in account. No method of storage or transmission is completely secure, so we cannot guarantee absolute security. If a breach affects your personal data, we will notify you as required by applicable law.

14. Children's Privacy

The App is not intended for children under 16 (or the higher minimum age required in your country), and ads shown in the App are not directed at children. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact us at arifewucse2016@gmail.com and we will delete it.

15. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with a new effective date, and where required by law we will seek your consent to material changes.
