Cutwave

Overview

Cutwave turns your photos and videos into an edit that lands on every beat of the music. Your memories are the raw material of the edit — so they never leave your iPhone.

Cutwave has no accounts to create, no advertising, and no tracking across apps or websites. We (the developer) operate no server. Your photos, your videos, your music and your finished edits stay on your device. The only thing the app can send anywhere is a set of anonymous usage statistics — and only if you say yes when asked (see below). It is off until you do.

Information We Collect

No personal information. We do not collect, receive, sell or share your personal information. There is no sign-up, no profile, and nothing of yours is uploaded to us — because there is no “us” to upload to. The one optional exception is described in Anonymous Usage Statistics.

Everything the app works with lives on your device:

• The photos and videos you choose are copied into the app's own storage so they can be edited. You pick them through Apple's system photo picker, which hands the app only what you selected — the app never browses your library.
• Music you import from your device is copied into the app's storage in the same way. The 50 built-in tracks ship inside the app.
• Your projects — the running order, the timing, your titles and credits, your settings — are saved locally so a project is never lost.

Everything Is Computed On Your Device

The parts of Cutwave that look like they need a cloud do not:

• Beat and tempo detection analyses the music with Apple's on-device signal-processing framework (Accelerate). There is no machine-learning model to call and nothing is uploaded.
• Choosing which shots deserve more screen time uses Apple's on-device Vision framework to score image quality and spot faces. That analysis happens on your iPhone and its results never leave it.
• Rendering the video is done on your device's own graphics hardware.

Cutwave works with no network connection at all, apart from the one optional feature below.

Place Names — the One Optional Network Feature

Cutwave can print the name of a place on your shots (“Krabi · July 2026”), taken from the location your camera already recorded in the photo. This is the only feature that uses the network, and it is switched off by default.

If you turn it on, the app sends the photo's coordinates — not the photo, not the image, not your identity — to Apple's geocoding service to get the name of the place back. That request is handled by Apple under Apple's Privacy Policy. Results are cached on your device so the same place is not looked up twice. Turn the switch off and no request is ever made.

Saving and Sharing Your Video

When you save a finished edit, Cutwave asks for permission to add it to your photo library — the “add” permission only, which does not let the app read your library.

If you then share the video to another app or a social network, you are handing it to that app through Apple's system share sheet. What happens to it next is governed by the privacy policy of whichever service you chose, not by this one.

Purchases

Cutwave offers one optional one-time purchase — no subscription — that removes the watermark and the end card, raises the media limit, and unlocks 1080p and 4K export.

The purchase is processed directly by Apple through the App Store using StoreKit. We never see, receive or store your payment details, card number or Apple ID. Apple handles the transaction, the receipt and any restore, under Apple's own Privacy Policy.

Data Storage & Deletion

Your projects and the media copied into them are stored on your device. If your iPhone backs up to iCloud, that on-device data may be included in your own private device backup, governed by Apple's privacy policy.

You are in control:

• Deleting a project removes its edit and the copies it holds. Your original photos and videos are never touched.
• Deleting the app removes all of its data from your device.
• A video you already saved to your photo library stays there — it is yours; delete it from Photos if you want it gone.

Anonymous Usage Statistics (Optional)

The first time you open Cutwave, the app asks whether you agree to share anonymous usage statistics. This helps us understand how the app is used — which formats, ambiances and openings people choose, how many edits get generated and shared, where the purchase screen is opened — so we can improve it.

• Off by default. Nothing is sent until you tap Accept. You can change your mind at any time in Settings → Anonymous statistics; switching it off stops all sending immediately.
• What is sent, if you accept: technical events such as “edit generated”, “format changed”, “opening picked”, “purchase completed”, together with device model, iOS version, app language, and country derived from your IP address by the provider. Purchases are reported with their price and currency for revenue statistics.
• What is never sent: your photos, videos, music, project names, titles, credits, place names, or anything that identifies you. No advertising identifier (IDFA) is used and the app never asks for tracking permission, because it does not track you. In Apple’s own terms, “tracking” means linking data from this app with data collected from other companies’ apps or websites for targeted advertising or advertising measurement, or sharing data with data brokers: Cutwave does neither, and the app ships without the advertising-identifier components of the analytics SDK.
• Crash reports are covered by the same choice: with the setting off — its default — Firebase Crashlytics collects nothing either. Both collectors are switched off before Firebase starts, and your answer turns them on together.
• How long it is kept: event-level statistics are retained by Google Firebase for the retention window configured on our Analytics property, which is at most 14 months; only aggregated, non-identifying reports are kept beyond it. Because nothing sent identifies you or your device to us, we cannot single out “your” statistics to retrieve or erase them individually — switching the setting off stops all sending immediately, and deleting the app removes the app’s local data. For any privacy request, write to mythadubiz@gmail.com.
• Provider: these statistics are processed by Google Firebase Analytics (and Firebase Crashlytics for anonymous crash reports), on Google's servers, under Google's privacy terms. Data is used only for aggregated statistics about Cutwave and is not shared with advertisers.

Third Parties

Cutwave contains no advertising SDKs and no cross-app tracking libraries. The external parties involved are Apple — for the in-app purchase (StoreKit) and, if you switch it on, for looking up place names — and Google Firebase, only if you opted in to anonymous usage statistics (see above).

Children's Privacy

Cutwave does not collect personal information, contains no advertising and no third-party content, and does not knowingly gather any data from children under 13. Anonymous usage statistics are optional and contain nothing that identifies a person.
