Effective date: October 2, 2026 · 日本語
This is the agreement between you and Kohei Omori, a sole proprietor based in Japan (the “Developer”), for the iPhone app FrameSmoother (the “App”). Downloading, installing or opening the App counts as accepting it. If you cannot accept it, please do not use the App; Part B explains how refunds work.

A-1 Relationship with Apple’s licence. This document applies to every dealing between you and the Developer that concerns the App. Because you obtain the App from Apple’s App Store, Apple’s Licensed Application End User License Agreement (the “Standard EULA”) governs it as well. Wherever the two disagree, the Standard EULA takes priority.
A-2 Supported devices. The App needs an iPhone on iOS 16.0 or newer. It is designed for iPhone 13 and later models; earlier iPhones may install it, but correct operation there is not promised. On models with less memory, the App applies tighter limits on the resolution of the videos it accepts.
A-3 What the licence allows. The Developer lets you run the App on Apple-branded devices you own or control, for your own non-commercial purposes. The licence is non-exclusive and cannot be transferred. It does not allow you to:
A-4 Conduct. In your use of FrameSmoother you must not:
B-1 One payment, then nothing more. FrameSmoother is sold once. It has no subscription, nothing renews automatically, and there is no free tier for ongoing use. Prices are set in App Store Connect and shown in each storefront’s own currency.
| Your situation | What you pay | Japan | United States |
|---|---|---|---|
| You buy FrameSmoother on the App Store | The App’s price, once; every feature is included | ¥300 | US$1.99 |
| You downloaded FrameSmoother while it was still free (before it became a paid app in July 2026) | The in-app purchase “Lifetime” (com.naruberio.framesmoother.lifetime), once |
¥300 | US$1.99 |
| You already bought “Lifetime” | Nothing further | — | — |
The Japanese price includes consumption tax. In the United States and some other storefronts, sales tax may be added at checkout. Other storefronts charge the amount Apple converts from these prices.
If you got the App while it was free, its features stay locked behind an unlock screen until “Lifetime” is purchased. That single purchase opens every feature; buying the App itself again is unnecessary.
B-2 How payment works. Apple charges the payment method on your Apple Account. Card numbers and billing details never reach the Developer. Neither the App purchase nor “Lifetime” renews or charges again. To bring “Lifetime” back on a new or reset iPhone, sign in with the same Apple Account and tap Restore Purchases on the unlock screen or in Settings.
B-3 Refunds. Whether money is returned is decided by Apple, not by the Developer. Request a refund at reportaproblem.apple.com; Apple describes the process in Request a refund for apps or content that you bought from Apple. The Developer accepts whatever Apple decides. If the App is misbehaving, email the address in Part G as well, so the Developer can look into the problem.
B-4 Future price changes. Prices may change later. A new price affects only purchases made after the change; it takes nothing away from what you have already bought.
C-1 Your videos. Anything you process with FrameSmoother remains yours. All processing happens on your iPhone and no video is sent off the device, so the Developer has no access to your footage. The App writes its output as a new file and leaves the original untouched.
C-2 The App itself. Copyright, trademarks and every other intellectual property right in FrameSmoother — its code, design, name, icon and other material — belong to the Developer or to the parties who licensed them.
C-3 Open-source components. The App contains open-source software, including the RIFE frame-interpolation model. The licence for each component is listed under Settings → Open Source Licenses inside the App.
D-1 Provided as it is. The App is supplied “as is”. The Developer does not guarantee that it is complete or accurate, nor that it fits any particular purpose.
D-2 Results vary. How good an interpolated video looks depends on the source: fast motion, objects crossing each other, low light and heavy compression can all produce visible artefacts. The Developer does not promise that every video will reach the quality you expect.
D-3 Cap on liability. If you suffer loss for which the Developer is at fault, the Developer’s liability is capped at the amount you had paid for the App or for “Lifetime” at the moment the loss arose. This cap does not cover loss caused by the Developer’s intentional misconduct or gross negligence.
E-1 Changes to the App. Features may be modified, added or removed without advance notice. Should the App be discontinued, the Developer will announce it beforehand in the App or on this page whenever that is possible.
E-2 Changes to this document. The Developer may revise these terms when needed. A revised version takes effect as soon as it appears in the App or on this page, and the effective date above is updated with it.
Japanese law governs these terms. Every dispute concerning the App will be heard first by the Tokyo District Court, which the parties agree has exclusive jurisdiction at first instance.
