Privacy Policy

Last updated: 2026-10-31

The short version

Your video and your voice stay on your iPhone. Writing down what you said, cutting, subtitles and export all happen on the device.
Only text is sent: for smart cuts, titles and subtitle corrections, the written text of what you said goes through our server to Anthropic (Claude) and the answer comes back. We don't store it.
To protect the service from abuse we use Apple’s App Attest/DeviceCheck and count usage per install (numbers only).
Purchases go through Apple. No account, no ads, no tracking, no analytics.

2. What happens on your iPhone

The videos you pick or record, their sound, and everything made from them stay on your iPhone. OneTapCut uses Apple’s on-device speech recognition to write down what you said, and cuts, adds subtitles, levels the volume and exports the video on the device. We never receive your video, your audio or your photos.

The app asks for access only when it needs it: the camera and microphone to record a video in the app, and your photo library to pick a video or save the finished one. You can change these permissions at any time in the iPhone Settings.

3. What is sent for the AI features

For smart cuts (repeats, restarts, a stronger start), title suggestions and subtitle corrections, the app sends to our server:

the written text of what was said in the video (the transcript, as text only),
its language, the length of the video in seconds, and the names and words you added under “Names & words”,
technical data needed to protect the service (see section 4).

Our server runs on Cloudflare Workers (Cloudflare, Inc.). It passes the text to the Claude API of Anthropic, PBC, and returns the answer to the app. We do not store the text, and our server logs contain no content — only numbers such as the number of words and the processing time. Anthropic processes the text on our behalf only to answer the request; under its commercial terms it does not use this data to train its models. See Anthropic’s privacy policy.

Cloudflare and Anthropic are based in the USA. Transfers rely on the safeguards in their data processing terms (such as the EU Standard Contractual Clauses). The legal basis is Art. 6(1)(b) GDPR: we process the text to provide the feature you are using. Without an internet connection the app still cuts your video, just without the AI suggestions.

4. Protection against abuse

App Attest / DeviceCheck: Apple confirms that requests come from the real OneTapCut app on a real device. We store the resulting device key and a counter; they contain no personal details.
Install ID: the app creates a random ID when it is installed. It is not linked to your name, Apple ID or advertising ID.
Usage counters: per install and day we count calls, videos and minutes of video (numbers only). They are deleted automatically after two days.
Daily totals: totals per day (number of calls and videos, text length in tokens, costs, processing time) and a list of the most active installs per day, identified only by a shortened one-way hash of the install ID. These are kept for up to 400 days to run the service and spot abuse.

Legal basis: Art. 6(1)(f) GDPR (our legitimate interest in a secure, affordable service).

5. Purchases

Subscriptions are sold and billed by Apple. We receive no payment details. The app checks your subscription status on your iPhone using Apple’s StoreKit.

6. No account, no ads, no tracking

OneTapCut has no user accounts, shows no ads, contains no analytics or tracking tools and no third-party SDKs, and does not track you across apps or websites.

7. Diagnostics

The app keeps a technical log on your iPhone. It is never sent automatically; only if you copy it and send it to us yourself. If you allow it in iOS, Apple may share crash reports with us without personal details.

8. This website

This website is hosted on Cloudflare Pages. To deliver the pages and protect them from attacks, Cloudflare processes technical data such as your IP address (Cloudflare’s privacy policy). The website sets no cookies, uses no analytics, and loads its fonts from our own server.

9. Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and to object to processing, and the right to lodge a complaint with a data protection supervisory authority. Because we store no content and no names, we usually cannot link stored numbers to you. Deleting the app removes the install ID and everything stored on your iPhone. Contact: info@hunglongvu.com.

10. Changes

We will update this policy when the app changes. The date at the top shows the current version.
