Privacy Policy - PDF Watermark Removal Master

1. Scope

This Policy applies to the PDF uploading, parsing, watermark removal, downloading, membership benefits, and Apple in-app purchase verification services provided by the App, as well as the servers and websites that support these functions. Services independently provided by third parties such as Apple and cloud service providers are governed by their respective privacy policies.

2. Information We Collect

1. Files and settings you submit

When you use the PDF processing features, we receive the PDF files you choose to upload, together with the file name, format, size, selected processing mode, text or images designated for removal, and other processing parameters. A file may contain your personal information or that of a third party, so please upload only files that you are authorized to process. We process files only in accordance with the processing instructions you actively initiate. We do not proactively identify, extract, or analyze personal information contained in your files, and we do not use file content for any purpose other than completing the processing service you specify.

2. Service user identifiers and membership information

To distinguish between users and associate processing records and membership benefits, the client may submit a service user identifier, membership level, and membership validity period to the server. This identifier is not your Apple ID password, and we will never ask you to provide your Apple ID password.

3. File processing and operational records

To display task progress, provide result downloads, troubleshoot faults, and protect service security, we may record file names, file identifiers, conversion types, processing status, processing time, result addresses, error information, request time, IP address, and necessary server logs.

4. Apple in-app purchase information

When you purchase or restore an auto-renewable subscription, we receive and process purchase receipts, product identifiers, transaction identifiers, original transaction identifiers, purchase and expiration dates, subscription status, refund or revocation status, and signed transactions and subscription notifications provided by Apple. Payments are processed by Apple, and we do not obtain your complete bank card information.

3. How We Use Information

To receive and process the PDF files you select and generate and provide processing results;
To display task status, processing history, and download access;
To verify Apple in-app purchases, restore purchases, and maintain subscription membership benefits;
To diagnose faults, prevent abuse, and protect server and user data security;
To handle inquiries, complaints, and requests to access or delete data;
To meet obligations required by laws, regulations, regulatory authorities, and transaction dispute resolution.

We do not sell your personal information or use the information described above for targeted advertising tracking across apps.

4. File Storage and Retention Periods

To complete processing and result downloads, uploaded source files, processed files, and certain files for which processing failed may be stored in cloud object storage. Download links may have an access validity period. All source files uploaded by users and all generated result files will be permanently deleted from the server no later than 6 hours after processing is completed, with no additional backup retained. Diagnostic log files retained because processing failed will also be automatically deleted within 7 days.

We retain relevant data only for the period necessary to complete file processing, provide downloads, troubleshoot faults, maintain security, and meet legal obligations. When data is no longer necessary for these purposes, we will delete or anonymize it in accordance with our operational schedule. You may also request deletion using the contact details provided in this Policy.

Membership, transaction, and subscription records may be retained while the subscription relationship remains in effect and for the period necessary to meet financial, audit, refund, dispute resolution, or other legal obligations.

5. Third-Party Services and Information Sharing

To provide the App's functions, we may use the following third-party services to the extent necessary:

Apple: for app distribution, in-app purchases, subscription status verification, refunds, and subscription notification processing;
Huawei Cloud OBS: for storing and transmitting files voluntarily uploaded by users and their processing results;
Other than the third parties listed above, the App does not integrate any other third-party services or SDKs.

We do not share your personal information with other third parties unless we have your authorization, sharing is necessary to complete a service you request or protect legitimate rights and interests, or laws and regulations require otherwise. We require service providers entrusted to process data to apply protections appropriate to this Policy and applicable law.

6. Information Security

We take technical and organizational measures appropriate to our business risks to protect information, including access controls, permission restrictions, transmission safeguards, log auditing, and anomaly monitoring. No internet service can guarantee absolute security. If a security incident may affect your rights and interests, we will take remedial measures and provide notice as required by applicable law.

7. Your Rights

To the extent provided by applicable law, you may request access to, correction, a copy, or deletion of information relating to you, withdraw consent you have given, or object to specific processing. Contact us at the email address at the end of this Policy and provide enough information to verify the request and the relevant service identifier. To protect data security, we may need to verify your identity first.

A deletion request does not affect processing carried out with your authorization before the request. Where information must be retained by law or is necessary to complete transaction settlement, handle refund disputes, or maintain security, we may be unable to delete it immediately, but we will restrict its further use and process it after the retention obligation ends.

Deleting the App does not automatically cancel an Apple auto-renewable subscription. To cancel a subscription, go to the Apple Account subscription management page in iOS Settings.

8. Protection of Minors

The App is not primarily intended for children under 14 years of age. Minors should use the App with the guidance and consent of a parent or other guardian, and should not upload files containing sensitive personal information or files they are not authorized to process. If a guardian discovers that a minor has provided us with personal information without consent, please contact us so that we can address it.

9. Updates to This Policy

We may update this Policy due to changes in features, data processing practices, or legal requirements. The updated Policy will be published on this page with its updated date. For changes that materially affect your rights and interests, we will notify you through an in-app notice or another appropriate method.

10. Contact Us

If you have questions about this Policy or wish to submit a request for data access, correction, deletion, or a complaint, email us at 351830907@qq.com. After receiving your request and verifying your identity, we will respond to and process it within 15 business days.
