CastSurf Privacy Policy
Effective September 2, 2026
CastSurf ("the app") is made by Chamomile Studio. This page explains what the app does with information. The short version: the app has no server of its own, and we never receive your data.
1. What we collect
Nothing. CastSurf has no backend, no accounts, and no analytics of our own. We do not collect, transmit, or store personal information.
The following is kept on your device only:
- Favorites and browsing history from the built-in browser
- App settings such as theme and language
- The name of the Cast device you last connected to, for automatic reconnection
This is deleted when you delete the app. It is never sent anywhere, including to us.
2. Advertising (Google AdMob)
When you use CastSurf for free, ads are shown through Google AdMob. To serve ads and prevent fraud, Google may collect device information such as the advertising identifier, IP address, and device model. See Google's Privacy Policy and how AdMob uses data.
iOS asks for your permission before apps can track you across other companies' apps and websites. If you decline, you still see ads, but they are not personalized. You can change this at any time in Settings › Privacy & Security › Tracking.
3. Subscriptions
Premium subscriptions are handled entirely by the Apple App Store. The app cannot see your payment details. It only asks Apple whether an active subscription exists. Payment information is covered by Apple's Privacy Policy.
4. Your local network and your content
- CastSurf needs local network access to find and connect to Cast devices on your Wi-Fi. This permission is used only for that.
- When you cast a photo or video from your device, the file is served from your iPhone directly to your TV over the same Wi-Fi. It does not pass through any server of ours.
- Photo library access is limited to the items you pick. The app never browses your library on its own.
- Screen sharing captures your screen only while a broadcast is running, and the video is sent straight to your Cast device. It is never recorded or uploaded.
5. Notifications
The app may ask permission to send notifications. It uses this for one thing: telling you that screen sharing paused for an ad while you were in another app. Notifications are created on your device — there is no push server.
6. Web browsing
The built-in browser loads pages you choose. Those sites set their own cookies and follow their own privacy policies, exactly as they would in Safari. CastSurf does not send your browsing anywhere, and it does not recommend or bundle any site.
7. Children
CastSurf is not directed at children, and we do not knowingly collect information from them.
8. Changes
If this policy changes, the updated version will be posted on this page with a new effective date.
