Privacy Policy
This Privacy Policy explains how Image Compressor ("the App", "we", "us", or "our") handles information when you use the App. We designed the App to compress images locally on your device, without requiring an account and without uploading your photos to our servers.
1. Information We Process
1.1 Photos and image files
The App lets you choose images from your device and compress them. These images are processed locally on your device. We do not upload your selected photos, compressed photos, or image contents to ByteForge Tools servers.
The App may read image metadata (such as dimensions and file size) to display previews, estimate output size, and perform compression. If you enable the "Keep photo metadata" option, the App may attempt to preserve metadata in the output image. Photo metadata can include information such as camera model, shooting time, and potentially location data (GPS), depending on the original image.
1.2 Advertising data
The App uses Google AdMob to display advertisements. AdMob may collect or use device identifiers, including the advertising ID, IP address, coarse location derived from IP, app interaction information, crash data, diagnostic data, and other information as described by Google's policies.
In regions where consent is required, the App uses Google's User Messaging Platform (UMP) to request and manage your choices for personalized advertising and related purposes. If you do not consent to personalized advertising, ads may still be shown, but they may be non-personalized.
1.3 App settings and local data
The App stores certain settings locally on your device, such as compression preferences, whether onboarding has been shown, custom output folder choices, recent compression sessions, and consent-related settings stored by Google UMP. This data is used to make the App work correctly and is not uploaded to ByteForge Tools servers.
1.4 Analytics and diagnostic data
The App uses Google Firebase Analytics and Firebase Crashlytics to understand how the App is used in aggregate and to detect and fix stability problems. These tools may collect aggregate usage events (such as when a compression starts or completes and how many images were processed), app and device information (such as app version, device model, operating system version, and language), an approximate region derived from your IP address, and crash and diagnostic data (such as stack traces and the state of the App at the time of a crash).
This information is aggregated and is not used to identify you personally. We do not send your photos, image contents, file names, or file paths to these services.
2. Permissions
- Photos / files access: Used to let you select images and save compressed outputs.
- Internet and network state: Used by advertising, consent, analytics, and crash-reporting SDKs.
- Advertising ID: Used by Google AdMob for advertising, subject to your consent choices and applicable law.
3. Third-Party Services
The App uses the following third-party services:
- Google AdMob — advertising. See Google Advertising Policy.
- Google User Messaging Platform (UMP) — consent management. See Google UMP documentation.
- Google Play services — Android platform services used by Google SDKs. See Google Privacy Policy.
- Google Firebase Analytics — aggregate usage analytics. See Firebase Privacy and Security.
- Google Firebase Crashlytics — crash and stability diagnostics. See Firebase Privacy and Security.
4. How We Use Information
- To provide image compression, preview, sharing, moving, renaming, and deleting features.
- To remember your local settings and recent sessions.
- To show advertisements and measure ad performance through Google AdMob.
- To comply with consent requirements in applicable regions through Google UMP.
- To understand aggregate usage and improve features through Google Firebase Analytics.
- To detect, diagnose, and fix crashes and stability issues through Google Firebase Crashlytics.
- To respond to feedback or support requests when you contact us by email.
5. Data Sharing
We do not sell your photos or upload your selected images to ByteForge Tools servers. Advertising-related data, aggregate analytics data, and crash diagnostics may be processed by Google and its partners according to Google's policies and your consent choices.
6. Data Retention
Images you select and compressed images you create remain on your device or in the folder you choose. You can delete compressed outputs from within the App or through your device's file manager or gallery app. Local App settings remain until you clear the App's data or uninstall the App.
7. Children's Privacy
The App is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, please contact us and we will take appropriate action.
8. Your Choices
- You can choose which images to process and where to save compressed files.
- You can disable metadata retention in the App settings.
- Where available, you can manage ad consent choices through the App's "Ad preferences" option.
- You can reset the advertising ID or limit ad personalization in your Android system settings.
- You can uninstall the App to remove locally stored App data from your device.
9. Security
We use platform-provided storage and Android security controls. However, no method of storage or transmission is completely secure. Please be careful when sharing photos that may contain sensitive image content or metadata.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
