Privacy Policy

Effective date: November 12, 2026

This Privacy Policy explains how Mushroom Studio ("we", "us", or "our") handles information when you use Cleanup for Android (the "App"). The App is designed to do all of its work on your device.

1. Information handled by the App

Only with the permissions you grant, and depending on the features you use, the App may access or process:

• Photos, videos and audio files and their metadata (file name, folder, size, dimensions, duration and date) to find duplicate, similar, blurry, screenshot, screen-recording and large items, and to compress media you select.
• Analysis results computed from your media, such as visual fingerprints (image hashes), sharpness scores, colour histograms, video frame fingerprints and file checksums. These are short numeric summaries, not copies of your media.
• Contacts (names, phone numbers and email addresses) to find and merge duplicate contacts at your request.
• Installed apps and usage statistics (app names, sizes and last-used time) if you grant Usage Access, to help you find apps you rarely use. Uninstalling is always confirmed by Android.
• Battery information (level, temperature, voltage, health and charge cycles) shown on the Battery Health screen. It is read live and not stored.
• App settings, such as theme, language, nightly scan preference and the space shown on the home-screen widget.

2. How information is used

The App uses this information only to provide its functions: scanning and grouping media, suggesting the best copy to keep, compressing files, merging contacts, showing app and battery information, playing the speaker-cleaning sound, and keeping the widget up to date. We do not use your media or contacts for profiling or advertising.

3. Local storage and retention

Analysis results are kept in a cache inside the App's private storage so later scans are faster. Settings are stored locally too. They remain until you clear the App's data or uninstall the App. Compressed files are saved to your device's media storage. Android backups, if enabled by the device owner or platform, may be governed by Android and Google account settings.

4. Background scanning

If the nightly scan is turned on, the App may analyse new or changed media in the background, usually at night while the phone is charging. This runs entirely on your device. You can turn it off at any time in the App's settings.

5. Deleting and changing your files

The App never deletes, moves or edits photos, videos, audio files or contacts without your action. Items are deleted only after you confirm; on Android 11 and later, Android shows its own confirmation and moves media to the system trash first. Merging contacts links duplicate entries using Android's contacts provider.

6. Advertising and third-party services

If a version of the App shows ads, they are provided by Google AdMob. Google may collect and use device identifiers such as the Android advertising ID, IP address and ad interaction data to serve and measure ads, under the Google Privacy Policy. You can reset your advertising ID or opt out of personalised ads in your Android settings. Ad providers never receive your photos, videos, audio files or contacts.

Links that open other apps or websites, such as Gmail or Google Play, are handled by those services under their own privacy policies.

7. Sharing and sale of data

We do not sell personal information. We do not share your media, analysis results, contacts or app list with Mushroom Studio servers or any third party.

8. Security

We use Android application-private storage to reduce access by other apps, and the App only reads data through the permissions you grant. No method of storage is completely secure. You are responsible for protecting access to your device.

9. Your choices and deletion

• Grant, limit (for example to selected photos) or revoke media, contacts and usage access at any time in Android Settings.
• Turn the nightly scan on or off in the App's settings.
• Clear all App data from Android Settings or uninstall the App to remove the local cache and settings.

The App does not create a Mushroom Studio user account, so there is no separate server-side account to delete.

10. Children's privacy

The App is not directed to children under 13, or the minimum age required in their jurisdiction. We do not knowingly collect personal information from children through a Mushroom Studio account or server.

11. Changes to this policy

We may update this Privacy Policy when the App, legal requirements, or data practices change. The effective date at the top identifies the latest version.
