Terms of Service for Duplicate Photo Cleaner

Terms of Service - Duplicate Photo Cleaner

Terms of Service

Application: Duplicate Photo Cleaner
Provider: Arum Communications Corp.
Effective date: 2026-05-11

These Terms of Service ("Terms") govern your use of the Duplicate Photo Cleaner mobile application ("the App" or "the Service"), provided by Arum Communications Corp. ("we", "us", "our"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. The Service

The App helps you find and remove duplicate files on your device, including duplicate photos, similar pictures, blurry photos, and large media files. All scanning and cleaning operations run on your device. The App does not upload your files or their contents to our servers.

2. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country) to use the App. By using the App, you represent and warrant that you meet this requirement and that you have the legal capacity to enter into these Terms.

3. License

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on a device that you own or control, solely for your personal, non-commercial use. You may not:

  • Copy, modify, distribute, sell, sublicense, or lease any part of the App;
  • Reverse engineer, decompile, or attempt to extract the source code, except as permitted by law;
  • Remove or alter any proprietary notices or labels;
  • Use the App in any manner that could damage, disable, overburden, or impair our services or those of our third-party providers;
  • Use the App to violate any applicable law or regulation, or to infringe the rights of others.

4. File Deletion — Important Warning

You are solely responsible for the files you choose to delete. Deletion through the App may be irreversible. We strongly recommend that you back up important files before performing any cleanup. We are not liable for any loss of data, files, or media resulting from your use of the App's deletion features.

The App's duplicate detection uses content hashing and the App's similarity detection uses perceptual hashing; these heuristics are accurate but not guaranteed to be perfect. Always review the files selected for deletion before confirming.

5. Permissions

The App requires access to your device's photos, videos, and other media in order to scan for duplicates and to delete files you select. You can review or revoke these permissions at any time in your device settings; doing so may limit or disable App functionality.

6. Subscriptions and In-App Purchases

Some features of the App are available only through a paid premium subscription. Subscription purchases are processed by Google Play Billing and managed through RevenueCat.

  • Billing: Subscription fees are charged to your Google account at confirmation of purchase and at the start of each renewal period, at the price displayed in the App at the time of purchase.
  • Auto-renewal: Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage and cancel subscriptions in your Google Play account settings.
  • Free trials and promotions: If a free trial or promotional period is offered, any unused portion is forfeited when you purchase a subscription, unless required otherwise by law.
  • Refunds: Refunds are governed by Google Play's refund policy and any non-waivable rights you may have under your local law. We generally cannot issue refunds directly; please contact Google Play support for refund requests.
  • Restore purchases: If you reinstall the App or change devices, you can use the "Restore Purchases" function to reactivate an active subscription tied to your Google account.
  • Price changes: We may change subscription prices from time to time. Where required by law, we will give you advance notice and the opportunity to cancel before the new price takes effect.

7. Advertising

The free version of the App is supported by advertising delivered by Google AdMob. Ad selection may use device identifiers and information about your device and the App.

8. Third-Party Services

The App integrates third-party services, including Google Play Services, Google AdMob, Google Analytics for Firebase, Firebase Crashlytics, Google Play Billing, and RevenueCat. Your use of those services is also governed by the applicable third-party terms and privacy policies. We are not responsible for third-party services and do not control their content, policies, or practices.

9. User Conduct

You agree not to use the App to:

  • Engage in any unlawful, harmful, fraudulent, or harassing activity;
  • Attempt to gain unauthorized access to any portion of the App or its related systems;
  • Interfere with or disrupt the integrity or performance of the App;
  • Distribute viruses, malware, or any other malicious code through or in connection with the App.

10. Intellectual Property

The App and all related content, including but not limited to source code, designs, graphics, icons, text, and trademarks, are the property of Arum Communications Corp. or its licensors and are protected by intellectual property laws. Except for the limited license granted in Section 3, no rights are granted to you.

11. Updates and Availability

We may release updates, bug fixes, or new versions of the App from time to time. We may also modify or discontinue the App or any feature, in whole or in part, at any time, with or without notice. We are not liable to you or any third party for any modification, suspension, or discontinuation of the App.

12. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS, OR THAT THE APP'S DUPLICATE OR SIMILARITY DETECTION WILL ALWAYS BE ACCURATE OR COMPLETE.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL ARUM COMMUNICATIONS CORP., ITS AFFILIATES, OR ITS LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR REVENUES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APP, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE, OR (B) USD 10.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you. Nothing in these Terms limits liability that cannot be limited under applicable law.

14. Indemnification

You agree to indemnify, defend, and hold harmless Arum Communications Corp. and its affiliates from and against any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of or related to your use of the App, your violation of these Terms, or your violation of any rights of a third party.

15. Termination

We may suspend or terminate your access to the App at any time, with or without notice, if you violate these Terms. You may terminate these Terms at any time by uninstalling the App. Sections that by their nature should survive termination (including ownership, disclaimers, limitation of liability, indemnification, and dispute resolution) will survive.

16. Governing Law

These Terms are governed by the laws of the Republic of Korea, without regard to its conflict of laws rules, except where mandatory consumer protection laws of your country of residence apply. Any dispute arising out of or in connection with these Terms shall be subject to the exclusive jurisdiction of the competent courts of the Republic of Korea, unless otherwise required by applicable law.

17. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Effective date" at the top of this page and, where appropriate, provide additional notice through the App. Your continued use of the App after such changes constitutes your acceptance of the updated Terms.

18. Contact Us

If you have any questions about these Terms, please contact us at developer@arumarum.com.

Privacy Policy for Duplicate Photo Cleaner

Privacy Policy - Duplicate Photo Cleaner

Privacy Policy

Application: Duplicate Photo Cleaner
Provider: Arum Communications Corp.
Effective date: 2026-05-11

Arum Communications Corp. ("we", "us", "our") built the Duplicate Photo Cleaner app ("the Service") as a free, ad-supported application with an optional paid subscription. This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use the Service, and the choices you have associated with that information.

By using the Service, you agree to the collection and use of information in accordance with this policy. We will not use or share your information with anyone except as described in this Privacy Policy.

1. Information We Process

1.1 Information processed only on your device

The Service scans your device storage to find duplicate files, visually similar pictures, blurry photos, and large media. To do this, the app reads:

  • File metadata (file name, file path, file size, modification date)
  • Image and video content for the purpose of computing local hashes (MD5 partial hashes for duplicate detection, perceptual hashes for similarity detection, Laplacian variance for blur detection)
  • The MediaStore content URIs needed to delete files you choose to remove

This information stays on your device. We do not upload your files, file names, file paths, thumbnails, hashes, or scan results to any server operated by us. Cleaning history is stored locally in a Room SQLite database on your device and is removed when you uninstall the app.

1.2 Permissions used

PermissionPurpose
READ_MEDIA_IMAGES / READ_MEDIA_VIDEO (Android 13+) Read photos and videos from device storage in order to identify duplicates, similar images, blurry photos, and large media.
READ_EXTERNAL_STORAGE (Android 12 and below) Same purpose as above on older Android versions.
WRITE_EXTERNAL_STORAGE (Android 9 and below) Required to delete files you select for cleanup on legacy Android versions.

1.3 Information collected by third-party services

The app uses third-party services that may collect information used to identify you or your device. These services may collect data such as device identifiers (Android Advertising ID), IP address, device model, operating system version, app version, language, country, crash logs, and aggregated usage events. Please review each provider's privacy policy linked in Section 4 below.

1.4 Subscription and purchase information

If you purchase a premium subscription, the transaction is processed by Google Play Billing and managed through RevenueCat. We do not receive or store your full payment instrument (e.g., credit card number). We receive an anonymous subscriber ID, purchase tokens, entitlement status, and purchase metadata such as country and product ID, in order to grant and validate your premium entitlement.

2. How We Use Information

  • To provide the core scanning and cleaning functionality (locally on your device).
  • To deliver advertising, including non-personalized ads where required by law or by your consent choice.
  • To measure app performance, diagnose crashes, and improve stability.
  • To validate and manage premium subscriptions.
  • To comply with legal obligations.

3. Legal Basis (EEA/UK Users)

Where the GDPR or UK GDPR applies, we rely on (a) your consent for advertising, analytics, and crash reporting that involve personal data, collected through Google's Consent Management Platform (CMP) shown on first launch; (b) the performance of a contract for subscription processing; and (c) our legitimate interests in operating and securing the Service. You can change your consent at any time from the in-app privacy settings.

4. Third-Party Service Providers and Their Privacy Policies

We use the following third-party services. Each link below leads to that provider's privacy policy and, where applicable, its description of the data it collects and how it is used.

5. Advertising and Your Choices

Ads are served by Google AdMob and may use the Android Advertising ID to deliver, measure, and limit the frequency of ads. You can opt out of personalized advertising at any time:

  • On Android: open Settings → Google → Ads and toggle "Delete advertising ID" or "Opt out of Ads Personalization".
  • For EEA, UK, or Swiss users, you may withdraw or change your advertising consent through the in-app privacy options, which re-displays the Google CMP consent form.
  • Learn more: Advertising ID, Google Ad Settings.

6. Log Data

When the app crashes or encounters an error, third-party tools (Firebase Crashlytics) may collect diagnostic data including device IP, device model, operating system version, app configuration at the time of the error, and the time and date of the event. This information is used solely to diagnose and resolve issues.

7. Cookies

The Service does not itself use cookies. However, third-party SDKs embedded in the app may use cookie-equivalent identifiers (such as advertising IDs) to provide their services.

8. Data Retention

  • Local scan results are kept only in the app's cache and are auto-cleaned after 1 hour.
  • Cleaning history is stored locally and is removed when you uninstall the app.
  • Subscription records are retained by RevenueCat and Google Play Billing for as long as required to maintain your entitlement and for legal/accounting purposes.
  • Crash and analytics data are retained according to each provider's standard retention periods.

9. Your Rights

Depending on your jurisdiction (EEA, UK, California, etc.), you may have rights to access, correct, delete, restrict, or port your personal data, and to object to certain processing. To exercise these rights, contact us at the email below. You also have the right to lodge a complaint with your local data protection authority.

10. Security

We take reasonable steps to protect the limited information processed through the Service. However, no method of transmission over the Internet or method of electronic storage is 100% secure, and we cannot guarantee its absolute security.

11. Links to Other Sites

The Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. These external sites are not operated by us. We strongly advise you to review the privacy policy of any site you visit. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

12. Children's Privacy

The Service is not directed to children under the age of 13, and we do not knowingly collect personally identifiable information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will delete it from our records. If you are a parent or guardian and you believe your child has provided us with personal information, please contact us so that we can take the necessary action.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective date" at the top.
