### 1/5 — Enforcing for showing Ads.

*2026-08-09, version 4.22.5*

Enforcing for showing Ads. without any time lapse or limit, there are no options for skip the ads after some seconds. I wish i will give them 0 star.

### 1/5 — LITERALLY UNUSABLE - TeraSucks

*2026-08-09, version 4.22.5*

This app will hit you with intrusive ads every few seconds - it's literally insane! Thankfully, I backed up all of my photos and won't be using TerraSucks anymore.

### 1/5 — Not it

*2026-08-07, version 4.22.5*

Rip off ad central🤦🏾‍♂️

### 1/5 — Unusable

*2026-08-07, version 4.22.5*

So so so soooooooo many ads that it doesn’t even let you actually use the app

### 1/5 — Ads

*2026-08-02, version 4.22.0*

This app is waste 🤬

### 1/5 — Too much ad

*2026-07-30, version 4.22.0*

Not easy to use for annoying ad

### 1/5 — Videos

*2026-07-29, version 4.22.0*

Cannot upload videos unless is premium

### 1/5 — Ads Ads & MORE ADS

*2026-07-28, version 4.22.0*

This app is just an ad machine with no correlation to what its marketed to be.

### 1/5 — Verifiably useless.

*2026-07-26, version 4.21.0*

Missing basic function in place of predatory advertising and pointless premium features. Wanna download something locally? Can’t. Want to play videos? Can’t. Want to unzip a file? Pay for premium! Just use Mega and Unzip on IOS, there is no reason for this app to exist.

### 1/5 — So difficult to work with

*2026-07-23, version 4.21.0*

Terrible app all I needed to download was one folder!! Something that takes 3 minutes (the size of Roblox) is taking two hours. The ads are crazy and they are clearly money hungry! I refuse to use this app again I only used it because I was forced to.

### 1/5 — Horrible

*2026-07-18, version 4.21.0*

This app is so money hungry because I can’t click two things without getting a whole bunch of ads thrown at me like cmon this is how u lose people to this app, I get keeping some ads but this is too much

### 1/5 — Annoying ads

*2026-07-18, version 4.21.0*

After every ad the app froze and need to be reset

### 1/5 — Absolute Garbage

*2026-07-15, version 4.21.0*

You will spend more time watching ads than you will actually using the app. This app is really garbage. Use mega for file storage, use google drive, use icloud storage, DO NOT USE THIS GARBAGE APP.

### 3/5 — Zuviel Werbung

*2026-07-14*

Leider zu viele zu lang dauernde Werbungen. Nutzung via Handy ist deshalb sehr schwierig, und langsame up.-  und down-load geschwindigkeit

### 1/5 — STAY FAR, FAR AWAY. SO MANY RED FLAGS.

*2026-07-12, version 4.21.0*

This is Flextech Inc. out of Tokyo, formerly Dubox by Baidu. Neither the terms of service nor the privacy policy mentions Baidu once. That is a choice. And it sets the tone for everything below.

Before you can even reach the terms and privacy policy links, the app puts its tracking permission demand in front of you. You're asked to consent to surveillance before you're allowed to read what you'd be consenting to. That's the handshake. Here's what's actually in the documents:

1. They profile your files. The privacy policy has you agreeing they can aggregate and analyze your information to build "label information" reflecting your "operation habits, interests, or credit," then use it for automated decision-making and marketing. A storage locker that opens your boxes and scores you.

2. The app reads your clipboard. It's a declared feature, supposedly only for invite codes and share links, with a promise they'll never look otherwise. Your clipboard carries passwords, 2FA codes, banking details, crypto seed phrases. Weigh that promise against a company that won't print its own corporate history.

3. Deletion is discretionary. You email a helpdesk, they "determine whether to accept your deletion request based on your usage," and if you have any data in your account they won't accept it immediately. No timeline given. It's a storage service. Having data in the account is the entire product. The deletion right functions mainly for empty accounts.

4. Facial recognition KYC on their say-so. When they deem it "necessary," you must hand over your real name, government ID number, and facial recognition data, which they may cross-check against government-authorized institutions. For a file locker.

5. Liability for losing your data: one month's fee. The all-caps section disclaims "ANY LOSS OF DATA, REGARDLESS OF LEGAL THEORY" and caps damages at what you paid that month. The one job the product has is the one thing they won't answer for. The same clause misspells "NEGLIGGNCE" and "ATTRIBTUED." They couldn't proofread their own liability cap.

6. Breach notification is optional. If they judge that their own cleanup "effectively avoided the harm," they may simply not tell you unless a regulator forces them. Self-graded homework, and you never see the report card.

7. Your data goes to governmental organizations "or their agents" without your consent, plus a disclosure exception for the "healthy development of youth," vague enough to cover anything with a badge or a mission statement.

8. No refunds after auto-renewal "for any reason." You're charged whether you use the service or not. All disputes go to courts in Tokyo under Japanese law. Your realistic remedy is an email and fifteen days of waiting.

The documents can't even agree with themselves. The terms say the minimum age is 15, the children's policy says 13, the guardian section says 18. The privacy policy for this alleged cloud drive contains entire sections on AI beautification and beauty filters. This paperwork was assembled from other apps' parts, and the "affiliates and certain third parties" who inherit permission to scan your files are never named anywhere.

This is a data acquisition funnel with storage bolted on. Stay the hell away.

### 1/5 — Chinese APP

*2026-08-24, version 4.23.6*

Don’t download it I unable to uninstall it

### 1/5 — Made by Jews

*2026-08-24, version 4.23.6*

So kikey

### 1/5 — The worst

*2026-08-20, version 4.23.6*

Didn’t even remove my storage

### 1/5 — Pop upd

*2026-08-18, version 4.23.6*

The app is useless. You can’t do anything because it will redirect you to a pop up website every single time you open it.

### 1/5 — Garbage app

*2026-08-18, version 4.23.6*

This app barely works and has too many ads. I couldn’t even download anything even with strong internet. Don’t waste your time on this trash.

### 1/5 — About this app

*2026-08-16, version 4.23.6*

The worst app I ever used .. A LOT of ads .. and even the wifi is fast they slow down the download on purpose so you can buy their subscription

### 1/5 — Useless and don’t get a terabyte for free

*2026-08-13, version 4.23.6*

Why do you have to pay gold to view a video or upload a file. Also you don’t get a terabyte for free I mean you do but it’s limited so you don’t get it forever unless you pay for premium and there are ads in there and like it’s just useless slop.

### 1/5 — Apple Store should ban immediately

*2026-08-13, version 4.23.6*

Never in my almost 20 years on the app store I have I seen a more blatant scamware/adware/AI-slop all-in-one app in my life. It’s honestly impressive

### 1/5 — Trash

*2026-08-12, version 4.23.5*

In free mode ads are coming continuously. Videos are not opening.

### 1/5 — Review

Bir tiyinga qimmat app,faqat reklama 0 ball,daje yulduzcha ham hayp silarga

### 5/5 — Hearts and hands

*2026-08-12, version 4.23.5*

We are lovers

### 5/5 — Yup

*2026-08-03, version 4.21.0*

Great

### 5/5 — 大容量かつ実用的

*2026-08-03*

無料で1TBのストレージを利用できるクラウドサービスというのはまず他に無いもので、そこが一番の強みであり、自分がヘビーユーズしている理由でもあります。

共有系のサービスであればこの様な高容量を売りにしたものを見かけること自体はあるのですが、高容量の他に日本の地域で利用ができるのは勿論のこと、各拡張子の利用が可能な汎用性の高さやクラウド解凍（展開）機能に加え、尚且つアップロードやダウンロードが容易に行えるという実用性も兼ね備えたクラウドサービスとしては、個人的にはこのTeraboxが中々の筆頭格でないかと思います。

UI周辺もアップデートを重ねるに連れて洗練され続けていて、保存した写真や動画、MP3などのデータを直感的な操作で閲覧できるので非常に重宝しています。

セキュリティーの面に関しては、Teraboxのメインのデータサーバーは日本にある（東京の森ビル）、国際機関によってISO認証が認定されている、という公式の記載を前向きに考慮するならば、ある程度担保はされていると感じます。
何であれ保存するデータを暗号化すれば相手側に内容を見られるという事はまずない（AES-256などによって暗号化されたデータの解読は現実的でないため）ので、その面において不安な方は使い方を工夫すればリスクは減らせると考えます。

動画のアップロードなどに関しても広告視聴などによって有効化できるリワード報酬を適用することで安易に有料会員のサービスを利用することができるので、無料で利用をするユーザーであっても大きな不便はなく利用ができる感じです。アップロード、ダウンロードの速度は著名なサービスと比べてやや力不足ではありますが、個人的には許容できる範囲かなと。

ネット社会という言葉が当たり前どころか陳腐ですら無くなった現代においては、この様な大容量のストレージを無料で利用できるサービスというのは現代の福祉といってもギリギリ過言では無いでしょう。非常にありがたいです。
