Privacy Policy for Reverse Image Search
Effective date: October 20, 2026

Photos and visual searches
You choose a photo from your library or camera. The app resizes the selected image and uploads it to Litterbox (Catbox), or to Uguu if that upload fails. Litterbox deletes uploads after 24 hours and Uguu after 3 hours. These services return a public image URL, which the app sends to Google Lens, TinEye, Yandex Images, and Bing Visual Search to perform your search. Anyone who obtains that URL may access the image while it is available. Do not choose an image you do not want shared with these providers.
We do not operate an image storage server or maintain our own copy of your uploads. The hosts control deletion and retention under their policies; these expiry periods do not control copies retained by search providers or others. Selected photos may remain in the app’s local temporary storage until removed by the app or operating system.
In-app browsing
Results open in embedded web browsers. Search providers receive the image URL, IP address, browser/device information, and interactions with their pages. They may use cookies, collect browsing or search activity, and show their own ads. Their policies govern those pages. The app has no account or sign-in requirement.
Advertising
Google AdMob serves interstitial ads. Its SDK can collect IP-derived approximate location, device identifiers, app interactions, advertising interactions, and diagnostic information to serve and measure ads and prevent fraud. On Android, the app uses the Android advertising identifier where available.
On iOS, we request privacy choices through Google’s consent system where required and request Apple’s App Tracking Transparency permission. AdMob may access IDFA only if you allow tracking. Declining tracking does not block image searches. Advertising choices can affect whether ads are personalized, limited, or unavailable. When required, a Privacy choices button lets you revisit your consent. You can also change tracking permission in iOS Settings → Privacy & Security → Tracking.
We do not sell photos or account information. Some advertising processing may constitute sharing or sale under applicable US privacy laws; the US privacy message provides an opt-out where applicable.
Analytics and crash reports
The app uses Google Analytics for Firebase and Firebase Crashlytics on iOS and Android to understand usage and fix failures. Analytics records app and session information (such as app opens, session length, app version, device model, operating system, language, and country or region derived from the IP address) and events such as selecting an image source, uploading an image, starting a search, switching engines, and displaying an ad. Crashlytics receives crash and error stack traces, device model, operating-system and app versions, diagnostic state such as free memory and disk space, and related usage breadcrumbs. Firebase uses installation and app-instance identifiers. We do not set a user account ID or send photos, image URLs, local photo paths, or search contents as analytics parameters.
The app tells Firebase not to use analytics data for advertising: ad storage, ad user data, and ad personalization signals are turned off, and on iOS Firebase’s advertising-identifier collection is disabled. Analytics and crash data are used only to understand and improve the app. They are not used to track you or to personalize ads, and they are not sold. This configuration is separate from the AdMob consent choices above.
Other data and retention
The app stores a search counter locally to skip ads on the first search. It is removed when app data is cleared or the app is uninstalled. Google Fonts may receive standard network metadata when fonts are downloaded. Network services receive IP address, device/browser information, and request times. Crashlytics keeps crash reports for up to 90 days; analytics data is kept under the retention settings of the app’s Google Analytics property. Advertising, browsing, analytics, and diagnostic data are otherwise retained according to the providers’ policies and service settings.
Your choices
Choose only photos you want to search. You can cancel the photo picker, revoke camera/photo permission in device settings, change tracking permission, revisit available privacy choices, or stop using the app. Depending on your location, you may have rights to access, correct, delete, restrict processing of, or obtain a copy of personal data. Contact us for assistance; requests concerning a search provider or image host may need to be addressed to that provider. There is no app account to delete.
Providers
Children, security, and updates
The app is not directed to children under 13. It accesses general web search results, which may contain mature material. We do not knowingly collect personal information from children. Services may process data internationally. App requests use HTTPS, but no transmission or storage system is perfectly secure. We update this policy when practices change and update the effective date above. Questions or privacy requests: rexyrex.dev@gmail.com.
