Privacy Policy

Last updated: October 26, 2026

Wallflow (“the App”, “we”) is a wallpaper app for Android and iPhone. This policy explains what information the App uses, why, who it is shared with, and the choices you have. It applies to the Wallflow apps and to this website.

Information we collect

Likes (random device ID)

The first time you open the App, it creates a random identifier and stores it securely on your device. When you favorite a wallpaper, the App sends this identifier and the wallpaper’s ID to our server so the like counts toward “Trending” and your likes can be restored. The identifier is not derived from your device hardware, phone number or advertising ID, and it is not linked to your name or any other personal information.

Technical information when the App loads wallpapers

Like any app or website, every request to our server includes your IP address and basic technical details such as the user agent. We use the IP address only to protect the service from abuse (for example, limiting how many requests can be made per minute). These short-lived counters are deleted automatically within minutes. Our hosting provider may also keep standard server logs for security and troubleshooting.

Usage analytics (off by default)

If you turn on Settings → Privacy → Share anonymous usage data, the App sends usage events to Google Firebase Analytics to help us understand which features and wallpapers people use. These events are:

• the App being opened and which screens are viewed;
• which wallpaper is opened, with its category;
• that a photo was imported, with only its width and height (never the photo itself).

Firebase also receives standard device information such as device model, operating-system version, app version and approximate country, along with an app-instance identifier. While this setting is off (the default), Firebase Analytics collection is disabled.

Advertising

The free version of Wallflow shows ads from Google AdMob. In regions where consent is required (for example the European Economic Area and the United Kingdom), the App asks for your consent through Google’s consent form before any personalized ads are shown. Depending on your consent and region, AdMob may use your device’s advertising ID, IP address and ad-interaction data to show and measure ads. On iPhone, ads are only personalized if you also allow tracking when iOS asks.

Information that stays on your device

The following is stored only on your device and is never sent to us:

• your favorites, and copies of favorite wallpapers saved for offline use and auto-rotate;
• your settings (theme, language, grid layout, reminders, auto-rotate);
• photos you import from your gallery and any edits you make (filters, text, stickers);
• daily reminder notifications, which are scheduled locally on your device. We do not use push notifications and do not collect a push token.

All of this is deleted when you uninstall the App or clear its storage.

Permissions

You can change or revoke permissions at any time in your device settings.

How information is shared

We share information only with the service providers that make the App work:

• Our hosting provider, which runs the server that delivers wallpapers and stores likes.
• Google AdMob for advertising (Google Privacy Policy, how Google uses data from apps).
• Google Firebase Analytics, only if you turn on usage analytics (Firebase privacy).

Wallpapers come from photographers on Unsplash, Pexels and Pixabay. The images are stored and delivered by our own server; the App does not send your information to those sites.

We may also disclose information if required by law. We do not sell personal information and do not share it for cross-context behavioral advertising beyond the ad consent you give to Google AdMob. Google services may process data in countries other than your own.

How long we keep information

• Likes: kept until you remove the like, or until the wallpaper is removed from the App.
• Abuse-protection counters based on IP address: deleted automatically within minutes.
• Analytics data (if enabled): kept by Google according to Firebase’s retention settings.
• On-device data: until you uninstall the App or clear its storage.

Your choices and rights

• Analytics: turn “Share anonymous usage data” on or off in Settings → Privacy at any time.
• Ads: where consent applies, open Settings → Privacy → Ad privacy choices to review or withdraw consent. You can also reset or delete your advertising ID in your device settings (Android: Settings → Google → Ads; iPhone: Settings → Privacy & Security → Tracking).
• Reminders: turn the daily reminder off in Settings → Notifications.
• Likes: remove any like by tapping the heart again. Uninstalling the App deletes your random ID from the device, and existing likes can no longer be linked to you.

Depending on where you live (for example under the GDPR in Europe or the CCPA in California), you may have the right to access, correct or delete personal information, to object to or restrict its processing, and to complain to your data-protection authority. Because the App has no accounts, we usually cannot identify which records are yours, but contact us and we will help where we can.

Children’s privacy

Wallflow is not directed at children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the App, please contact us and we will delete it.

Changes to this policy

We may update this policy when the App changes. We will update the date at the top of this page, and for significant changes we will make reasonable efforts to let you know in the App or on our store listings.
