Personalised vs Non-Personalised Ads
AdMob may show personalised ads based on your Advertising Identifier (IDFA). You can opt out of personalised advertising at any time:
If you opt out, ads will still appear in the app but will not be personalised to your interests.
LensMaster Pro
Purchasing LensMaster Pro ($4.99, one-time) removes banner ads and interstitial ads. Rewarded ads remain available as a voluntary way to earn bonus XP.
LensMaster is not directed at children under 13 years of age and we do not knowingly collect personal information from children. The App is rated 4+ on the App Store and does not contain content inappropriate for any age group, but it is designed for adult photography enthusiasts.
If you believe we have inadvertently collected information from a child under 13, please contact us and we will take steps to delete it.
All local data (progress, preferences, custom recipes) is stored on your device and controlled entirely by you. To delete all app data, simply delete LensMaster from your iPhone โ iOS will remove all associated UserDefaults data automatically.
For advertising data collected by Google AdMob, please refer to Google's Privacy Policy for data deletion requests.
If you are located in the European Economic Area (EEA) or California, you may have additional rights regarding your personal data, including:
Since LensMaster stores no personal data on our servers, most of these rights are satisfied by deleting the app. For AdMob-related requests, contact Google directly. For any other requests, email us at the address below.
The only third-party service used by LensMaster is:
Apple's StoreKit is used for in-app purchases (LensMaster Pro) and is governed by Apple's own privacy policy. We receive no payment details โ all transactions go through Apple.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
