Experience & key features
What Kwai is
Kwai is a short-video app published by Joyo Technology, part of Kuaishou. On Google Play it describes itself as a platform to watch, create and share videos, in a TikTok style. Caixin reports Kwai has operated in Brazil for about eight years, with about 60 million monthly active users there according to third-party data cited by the company.
Key features
Per the Google Play description: videos by interest, challenges and trends, duets with creators, effects, offline video downloads, sharing to WhatsApp, Instagram and Twitter, and private messages. Live streaming is enabled only for users who meet requirements. In Brazil, Kwai launched Kwai Shop in 2024; Kwai Lite, an app under 5MB, appeared in March 2025 according to Kwai's newsroom.
Pricing and rewards
Free to download and use. On the US App Store there are Diamonds packs at 0.99–99.99 USD and Refill packs at 0.99–7.99 USD. Google Play says users can make extra money by creating content; Common Sense Media notes real-money and virtual rewards for watching videos. Some Google Play reviews complain that ads were watched without the reward arriving.
More analysis
Compared with alternatives
Kwai competes directly with TikTok, Instagram Reels and Likee. Its edge is its large Brazilian community and Kwai Shop for selling; points to weigh are the hard-to-access privacy policy and Common Sense Media's 16+ rating.

Privacy
Kwai's full privacy policy could not be read when checked (the page rendered empty), so it is not summarised here. According to the Google Play data safety section, the app may collect location, personal info and 10 other data types, may share photos and videos with third parties, encrypts data in transit and lets you request deletion. Kwai's cookie policy names advertising partners such as Google and Facebook, says they do not collect this information from the Kwai app on iOS, and says Kwai does not currently respond to Do Not Track signals. Common Sense Media notes location data is used to show nearby users and the policy was hard to find in English (review based on version 2.24.5, updated 1 November 2022).

Why this score
Familiar scrolling-video model; App Store 4.5/5 and Google Play 4.0/5 across 11 million+ reviews. Some reviews report server connection errors.
Why this score
Video recording and editing, effects, duets, private messages, conditional live streaming, Kwai Shop. Nothing clearly ahead of the category leaders.
Why this score
Free to use but with ads; money is only spent on optional Diamonds (0.99–99.99 USD on the US App Store).
Why this score
Google Play 4.0/5; some reviews cite failed profile and video uploads or rewards not credited after watching ads.
Why this score
Support is mainly by email at [email protected]; the developer replies to some Google Play reviews, usually by pointing users to that email. No chat or phone channel found in the pages reviewed.
Why this score
The full policy could not be read when checked, which is itself a transparency gap. The data safety section lists location, personal info and other data types, and sharing of photos and videos with third parties; Common Sense Media raised concerns about location use and no friends-only option (2022 version).
