Privacy policy, terms of use and credits
Effective 13 October 2026 · Applies to the HalloweenSelfie app for iPhone
In short: your data stays on your phone.
- The app has no servers, no accounts and does not send data anywhere.
- We do not store any information about you, or anyone in your photos, on any server or with any third party.
- No analytics, no advertising, no tracking.
Privacy policy
HalloweenSelfie is a prank camera: you take a selfie with a friend, a ghost appears behind them, and their reaction is recorded. All of this happens on your device.
We do not collect, save or receive any data. The app contains no code that sends information to a server. It has no user accounts, no analytics, no advertising and no third-party tracking or data-collection services. We, the developer, cannot see your photos, videos, face scan or anything else you do in the app.
What the app keeps on your device only:
- Your face scan – a list of numbers describing the owner's face (not a photo), so the app can recognize you. See below.
- Your pranks – the videos and photos you record, in the app's gallery.
- Your settings – such as which ghost and sound you picked.
The app asks for these permissions:
- Camera – to show the selfie preview, find faces and record pranks.
- Microphone (optional) – to record sound with prank videos.
- Photos, add only (optional) – to save your pranks to your photo library. The app cannot see your existing photos.
When data leaves your phone, it's because you sent it. If you tap Share and pick an app such as TikTok, Instagram or Facebook, the video goes to that app and is handled under its terms and privacy policy. If your Photos library syncs with iCloud, saved pranks sync as part of Apple's service, which you control in your iPhone's settings.
Deleting the app deletes everything it stored. Pranks you saved to Photos or shared stay where you put them.
Why the app uses face recognition
The prank only works if the ghost appears behind your friend and never behind you. To tell you apart, the app asks the owner for a short face scan when it's first opened.
- The scan is turned into a numeric description of your face and stored only on your phone. It is never uploaded or shared.
- Faces of other people in the camera view are analyzed live, frame by frame, only to decide where the ghost goes. They are not stored or recognized as specific people.
- All face processing uses Apple's on-device Vision framework.
- You can delete your scan at any time with Re-scan my face in the app's settings, or by deleting the app.
Terms of use
- Prank responsibly. Only publish or share a prank if everyone in it agrees. You are responsible for what you record and share, and for respecting the privacy and image rights of the people in it.
- Don't use the app to harass, bully or frighten people who could be genuinely harmed, for example people with heart conditions, anxiety or young children.
- Videos and photos you create belong to you. The HalloweenSelfie watermark and end card on recordings may not be removed to pass the app's content off as your own work.
- The app is provided "as is", without warranties. To the extent permitted by law, the developer is not liable for how recordings are used or shared.
- Recommended for ages 12 and up because of mild horror themes.
Children
HalloweenSelfie is not directed at children under 13 and is rated 12+ for mild horror themes. Because the app collects no personal data at all, it does not knowingly collect data from children of any age.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new effective date. Material changes will also be noted in the app's release notes.
