Terms of use
The terms, in plain words.
Ninja's compressor is free, runs entirely on your phone and never receives your videos. These terms are short because there isn't much for them to govern.
Last updated
Who these terms are with
Ninja (listed as Ninja Video Compressor on Google Play and Ninja Video Compress & Convert on the App Store) and this website are published by Aviad Katani (Katani Labs) — "we" below. If you downloaded the app from the App Store, Apple's standard end-user license agreement also applies; from Google Play, Google's terms do. These terms add to theirs.
Using Ninja
Ninja's compressor is free. You may use it for any lawful purpose, personal or professional, on as many devices as you like. There are no accounts and no ads.
Ninja Pro
Ninja Pro is an optional in-app purchase. It unlocks batches of more than 3 videos, the advanced tools (cut the middle, merge, speed, reverse, watermark, subtitles, extract audio and GIF maker), H.265 / VP9 / AV1 encoding and unlimited saved presets. It's offered as App Store: $2.99 / month, $14.99 / year, $29.99 once; Google Play: $0.99 / month, $5.99 / year, $14.99 once — US prices; the store shows the price in your currency before you buy.
- Who you pay. Purchases are made through Apple's App Store or Google Play, under their terms. They process the payment; we never see your payment details.
- Renewal. Monthly and yearly subscriptions renew automatically at the then-current price until you cancel. On iPhone, cancel at least 24 hours before the period ends to avoid the next charge.
- Canceling. Cancel anytime in your App Store account settings or in Google Play → Payments & subscriptions. Pro stays on until the end of the period you paid for; deleting the app doesn't cancel a subscription.
- Lifetime. The one-time purchase unlocks Pro for as long as Ninja is available on your store account, with no renewal.
- Refunds. Refunds are handled by Apple or Google under their policies. A refunded or revoked purchase ends Pro.
- New phone. Use Restore purchases on the Pro screen with the same store account. There's no Ninja account to link stores, so a Google Play purchase doesn't carry over to the App Store, or the other way round.
We may change what Pro includes or costs in future versions. A price change never applies to a period you've already paid for, and the stores tell you about subscription price increases in advance.
Your videos stay yours
Everything you process in Ninja stays on your device, and we never receive it — so we claim no rights over it and have nothing to license from you. You're responsible for having the right to edit, convert and share the videos you work with.
Your originals
Ninja won't move, replace or delete an original until the compressed copy has passed nine checks, and you choose what happens to it. Some choices can be undone — the Ninja Vault, your phone's Trash (Recently Deleted on iPhone), and a ten-second undo after each batch. "Delete permanently" (Android only) can't be undone, by us or anyone. Keep backups of anything you can't afford to lose.
Open source
Ninja includes open source software, listed on the licenses page. Those licenses give you rights these terms don't limit. In particular, you're permitted to modify the LGPL-covered libraries for your own use and to reverse-engineer Ninja to debug such modifications.
No warranty
We build Ninja carefully, but it's provided "as is", without warranties of any kind. Phones, encoders and file formats vary more than any test can cover. To the fullest extent the law allows, we aren't liable for lost data, lost videos or any indirect damage arising from using the app or this website. Nothing here limits rights you have that can't be waived under the law where you live.
Changes
If these terms change, the new version will appear here with a new "last updated" date.
