FaceLapse

1. Overview

TezStudio ("we") respects user privacy in FaceLapse ("the App") and handles data according to this policy.

2. Face Photos (Face Data)

What we collect

The App collects selfie images (JPEG) and their EXIF metadata (capture date) that the user explicitly adds by tapping the shutter button or importing from the device's photo library.

How face data is used

• Displayed chronologically on the Album screen
• Used to render timelapse video (MP4) or animated GIF
• User-selected color filters (LUT color matrix) applied to the user's own photos
• (Pro users) Eye Alignment — on iOS, Apple Vision; on Android, the device's built-in face detection (Google ML Kit, etc.) runs entirely on-device to obtain two eye coordinates per frame and compute an affine transform that stabilizes the timelapse. Face identity, face geometry, and face embeddings are NOT stored or transmitted.

Storage

Face photos are stored exclusively on the user's device (the App's sandboxed Documents directory). They are never uploaded to our servers or any external cloud, and are not shared with the analytics or advertising SDKs described in section 3. The profile name you enter is also never sent to analytics or any server.

Third-party sharing

Face photos are NOT shared with any third party. The advertising SDK (Google AdMob) does not access face photos. They are transmitted to other apps only when you explicitly invoke the iOS or Android share sheet (e.g., Messages, Mail).

Retention

Face photos are retained until the user deletes them in-app or removes the App. There is no automatic deletion. On deletion, files are immediately removed from the device's file system.

3. Advertising, Analytics, and Crash Reports

• Google Mobile Ads (AdMob) — may show interstitial ads to free users. AdMob can process advertising identifiers (IDFA on iOS, Advertising ID (AAID) on Android), device information, and IP address. See the Google Privacy Policy.
• Google Analytics for Firebase (GA4) — sends app usage events, user properties (app_language, install_date, notif_enabled), and a random app-instance ID generated per install. Face photos, profile names, and EXIF are not included.
• Firebase Crashlytics — collects device model, OS, app version, and stack trace when the App crashes. Face photos and profile names are not included.
• Firebase Remote Config — fetches server-side settings such as the free-tier export limit, processing a Firebase installation ID in the process.

Analytics and Crashlytics are off in development, test, and simulator builds, and always on in released builds. The App does not provide an in-app opt-out.

Declining ad tracking — iOS: Settings > Privacy & Security > Tracking. Android: Settings > Privacy > Ads > "Delete advertising ID" (depending on device and Android version, this may appear under Settings > Google > Ads). All app features remain available if you decline; non-personalized ads will be shown instead.

4. Retention and Deletion

App data is removed when the App is uninstalled. iCloud backups follow Apple's iCloud policy.

5. User Rights

Users may request access, correction, or deletion of their data at any time. Contact: supports@tez.kr

6. Changes

If this policy changes, we will notify users via the App or this page.
