Privacy Policy for OptiSqueeze

Effective date: June 23, 2026

OptiSqueeze ("the App", "we", "us") is an Android application that compresses images and PDF files directly on your device. This Privacy Policy explains what information the App accesses, how it is used, and the choices you have.

1. Files you compress are processed on your device

OptiSqueeze never uploads the photos, images, or PDF files you choose to compress to any server. All compression (image re-encoding and PDF rasterization/re-embedding) happens locally, in memory and in the app's private cache, using on-device libraries. When you tap "Save," the compressed output is written to the public Downloads/OptiSqueeze folder on your device using Android's MediaStore (or, on Android 9 and below, a direct file write) so you can access it from your Files app. We do not have access to, and do not collect, the content of these files.

2. Information we collect

The App does not require you to create an account, sign in, or provide personal information such as your name, email address, or phone number to use its core features. The App does, however, use the following third-party services, which may collect limited technical data automatically:

ServicePurposeData involved
Google AdMob (native ads) Displays in-app advertisements that support the App's development Advertising ID, IP address/approximate location, device and app info, ad interaction data. See Google's policies linked below.
Firebase Analytics Understands feature usage and app performance in aggregate App usage events, device/OS info, approximate location (country/region), installation identifier
Firebase Crashlytics Detects and diagnoses app crashes Crash logs, stack traces, device model, OS version, app version
Firebase Performance Monitoring Measures app startup time and responsiveness Performance traces, network request timing, device/OS info

None of these services receive the content of your compressed files. They may collect device identifiers and usage statistics as described in their own privacy policies:

3. Permissions the App requests

PermissionWhy it's needed
INTERNET / ACCESS_NETWORK_STATE Required to load ads and send analytics/crash data to Firebase and AdMob.
AD_ID Lets AdMob use the Android Advertising ID to serve and measure ads.
WRITE_EXTERNAL_STORAGE (Android 9 / API 28 and below only) Needed on older Android versions to save compressed files to the Downloads folder. Not used on Android 10+, which relies on MediaStore instead.

The App also lets you pick image and PDF files via the system file/photo picker. This does not grant the App broad access to your storage — only the specific files you select are read.

4. Data stored on your device

Compression history (file names, sizes, and timestamps of past compressions) and app settings (such as your preferred compression quality) are stored locally on your device using Android's SharedPreferences. This data is not transmitted to us and is removed if you clear the App's data or uninstall it.

5. Data sharing and sale

We do not sell your personal information. Data described in Section 2 is shared only with the named service providers (Google AdMob, Firebase) for the purposes stated above, under their own privacy and data-processing terms.

6. Data retention

Locally stored history and settings persist until you clear the App's data or uninstall the App. Data collected by Firebase and AdMob is retained according to Google's own retention policies, which you can review at the links in Section 2.

7. Children's privacy

OptiSqueeze is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can address it.

8. Your choices

9. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Effective date" above. Continued use of the App after changes are posted constitutes acceptance of the revised policy.
