This App is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information through this App, please contact us at lazeeeedude@gmail.com and we will take steps to delete such information promptly.
For users in the European Economic Area (EEA): this App is not intended for users under the age of 16 (or the applicable minimum digital consent age in your member state).
All data processed by the App is stored locally on your device. No personal data is transferred to our servers. However, when you fetch wallpapers, your network requests travel to Unsplash's servers (located in the United States) and picsum.photos servers. By using the App, you acknowledge that these requests may involve international data transfers governed by the privacy policies of those third parties.
If you are located in the EU/EEA, you have the right to access, rectify, erase, restrict processing of, and port your personal data, as well as to object to processing and to lodge a complaint with your local Data Protection Authority (Articles 15–21, GDPR).
Since the App processes no personal data on any server we operate, most GDPR rights can be exercised directly on your device by clearing App data. For any other requests, contact lazeeeedude@gmail.com.
Legal basis (GDPR Art. 6): Processing of search queries sent to Unsplash is based on performance of the service you requested (Art. 6(1)(b)) and our legitimate interest in providing wallpaper content (Art. 6(1)(f)).
If you are a California resident, you have the right to know, access, delete, and opt out of the sale of your personal information, and to non-discrimination for exercising your rights.
To exercise any right, contact lazeeeedude@gmail.com. We will respond within 45 days as required by the CCPA.
The App does not use tracking technologies, does not set cookies, and does not implement any form of cross-app or cross-site tracking. "Do Not Track" browser signals are not applicable to this App.
We may update this Privacy Policy from time to time. When we do:
If you have any questions, concerns, or requests regarding this Privacy Policy, please contact:
We will respond to verifiable requests within 30 days (or sooner as required by applicable law).
This Privacy Policy is effective as of May 10, 2026 and replaces all prior versions.
