We take your privacy seriously. This Privacy Policy applies to the "SuperWatermark" application (hereinafter "the App") developed and operated by the developer. Please read and fully understand this Privacy Policy before using the App. By starting to use the App, you confirm that you have read and agree to this Privacy Policy.
The App is a fully offline image-watermarking tool whose core features work without any network connection. We do not collect, upload, or store any of your personal information on any server. Specifically:
1. Photo picking: The App lets you pick photos to watermark through the built-in iOS photo picker (PHPicker). This process is hosted by the system and does not require photo-library access permission; we do not read, scan, or collect any other photos in your library. The photos you choose are used only on your device, in the current session, for watermarking.
2. Watermark processing: The "Text Watermark", "Image Watermark", "Time Watermark", "Batch Watermark", and "Batch Image" features composite watermarks onto your chosen photos using the iOS Core Graphics and Core Image frameworks. This is done entirely on-device; no image data is uploaded, and no watermark content is stored externally.
3. Saving to Photos (optional): Watermarked results are saved by default only in the App's local sandbox storage. If you choose "Save Image" to your Photos library, iOS will ask for your "Add Photos" permission; this is entirely your choice.
4. Locally stored data: The App stores the following data on your device: watermarked result images (in the app sandbox), a history index (relative image paths and creation times), and user preferences. All of this data stays on your device and is never uploaded to any server.
The App does not collect your personal information. On-device data is used only to:
1. Composite text, image, or timestamp watermarks onto the photos you choose;
2. Save watermarked results locally so you can view or re-edit them at any time;
3. Maintain the history of your watermarking operations for convenient review.
All image processing happens on your device (using iOS Core Graphics and Core Image frameworks); no network data transmission is involved.
1. The core watermarking features run fully offline and work without a network connection.
2. All user data (including watermarked images and the history index) is stored only in your device's local sandbox.
3. We never upload any of your personal or usage data to cloud servers.
4. We never share, provide, or sell your data to any third party.
5. When you delete history in the App or uninstall the App, the related local data is removed.
The App integrates no third-party analytics, advertising, social-sharing, or user-behavior SDKs, and performs no data tracking or network requests of any kind.
1. The Privacy Policy and Terms of Service are bundled with the App as local built-in documents; reading them in the App requires no network connection and does not open any external web page;
2. Only when you tap "Feedback" does the App invoke the system mail app so you can send us comments; the email content is written by you and no personal data is transmitted automatically.
You have the following rights and may exercise them at any time:
1. Manage the App's permissions in iOS Settings;
2. Delete a single history item or clear all history data in the App;
3. Decide for yourself whether to save watermarked results to Photos;
4. Uninstall the App at any time to permanently remove all local data.
The App is primarily intended for adult users. If you are a minor under 18, please use the App under the guidance and with the consent of a legal guardian. We do not knowingly collect personal information from minors.
We may revise this Privacy Policy from time to time. When material changes occur, we will notify you in the App by appropriate means. The updated policy takes effect once published. We recommend reviewing this policy periodically.
