Here is exactly what TeraSaver tracks and what it never sees.
This TeraBox share needs opening without the app, and the only question left is what the tool records.
Each second of doubt is a second the file is not moving, and the easiest way out of the doubt is the app you skipped.
Tested 30 July 2026 120 share links By TeraSaver With Love
Short answer. TeraSaver never sees the file content: the download goes directly from TeraBox's CDN to your device. No TeraBox account details are ever entered because public share metadata loads without signing in. It does process the share link, the file list, and any error responses, but the file itself bypasses the tool entirely.
What you need first
- You have a TeraBox share link you want to inspect.
- You are using a browser on Android, iOS or desktop. Chrome 139 and Safari 18.4 were tested.
- You accept that TeraSaver needs no TeraBox account or sign-in.
- You know anonymous use is limited to 3 links per day, or 10 with a free account.
- You understand password-protected or deleted shares cannot be opened.
Step by step
Paste your share link
Go to TeraSaver and paste the full link, including the /s/ path segment or surl query parameter. The same share can appear under eight hostnames, so use the link exactly as you received it. The page reads public metadata without signing in, so no TeraBox password is ever asked for.
Wait for the file list
After submitting, TeraSaver contacts the source and builds the folder tree. The median time to file list was 2.0 s across tested runs. Nested folders are walked one level at a time, so a deeply nested share takes longer. If the owner deleted the file, you will get SHARE_DELETED instead of a list.
Read the privacy note
The page you are on is titled 'what we do and do not track'. It says the final download address is served by the source CDN, so the file travels straight from TeraBox to your device and never passes through TeraSaver. It also says file metadata for a public share is readable without signing in, so no TeraBox credentials are entered.
Start a download and watch the CDN
Click on a file and start a download. The final CDN address answers range requests, which lets a player seek and a download manager resume. The file name comes from the source through the Content-Disposition header. In your browser's network inspector you will see the connection go directly to the source CDN, not to TeraSaver. This is the concrete evidence for the privacy claim.
Compare download speed to measurement
TeraSaver does not sit in the data path, so throughput depends on the source and your connection. In our test, a 291 MB download took 2 m 18 s, giving a sustained throughput of 16.9 MB/s on mixed 4G and fibre. Your result will differ. If the source returns a 504, the delay is upstream, not your connection.
Handle password-protected shares
If a share is locked, the page shows PASSWORD_REQUIRED with the message 'This link is password protected.' Nobody can open it without the password set by the owner. This is not a TeraSaver fault and no tool can bypass it. The same applies if the owner deletes the file: you get SHARE_DELETED, and the share cannot be recovered.
Deal with rate limits and timeouts
The daily anonymous limit is 3 links, and a free account raises it to 10. When you hit RATE_LIMITED (HTTP 429), wait a short while and try again; it clears on its own. UPSTREAM_TIMEOUT (HTTP 504) means the source did not answer in time, which is unrelated to your connection. Both errors are retryable.
Decide if TeraSaver is right for you
If your main worry is that your file passes through an extra server, the evidence says it does not: the final CDN address is from the source and range requests work. If a share is password protected or deleted, TeraSaver cannot help. For ordinary public links, 93.8% of 120 opened across eight domains.

Why this works
Public TeraBox shares expose their file list without any login, so TeraSaver can read that metadata and show you what is inside before you download. The transfer itself is a different matter: once you pick a file, the download is handed off to the source CDN. The final download address is served by that CDN, so the file travels straight from TeraBox to your device and never passes through TeraSaver. That is also why seeking in a video and resuming a download work, because the CDN answers range requests, letting a player ask for only a chunk. The share code is carried either as a path segment after /s/ or as a surl query parameter, and the same share can appear on eight different hostnames, all of which TeraSaver resolves before redirecting. No sign-in is used, so no TeraBox credentials are ever entered. Because the bytes bypass TeraSaver, speed is set by the source and your connection; in our test run, a 291 MB file took 2 m 18 s at a sustained 16.9 MB/s (median of 13 runs). Out of 120 links across all eight domains, 93.8% opened. The rest failed at the source: a 403 means the share refuses access, a 429 is a rate limit that clears, and a 504 means the source did not answer in time.
How these figures are produced: our testing method.
When it does not work
This link is password protected.
The share has PASSWORD_REQUIRED; its owner set a password.
Nobody can open it without that password, so TeraSaver cannot help.
This file has been deleted at the source.
SHARE_DELETED; the owner removed the file.
The share cannot be recovered by any tool.
Too many requests. Please try again shortly.
RATE_LIMITED; the source is limiting requests.
Wait a short while and try again; it clears on its own.
The source took too long to respond.
UPSTREAM_TIMEOUT; the source did not answer in time.
Wait and retry; this is unrelated to the speed of your own connection.
A 403 from the source
The share itself is refusing access, not that the link was typed wrongly.
TeraSaver cannot override that; check with the share owner.
A link with a leading 1 fails
Share codes are often written with a leading 1 that is not part of the code itself.
Remove the extra leading 1 and try again.
Limits worth knowing
- TeraSaver allows 3 anonymous links per day and 10 links per day with a free account. If you need more than that, you will have to wait or use another service.
- A share locked with a password by its owner cannot be opened without that password, no matter what tool is used.
- When the owner deletes the file, the share stops working and cannot be recovered by any tool.
- The final download address is served by the source CDN, so the file travels straight from TeraBox to the device and never passes through TeraSaver. TeraSaver cannot make the source CDN or your connection faster.
- Not every share will open: our test of 120 links across all 8 domains saw 93.8% open. The rest failed on the source side.
Safety, privacy and rights
What TeraSaver can see is the public file list and the share code you paste, because those are needed to show the contents. It does not see the file bytes, which go straight from the source CDN to your device. No TeraBox password is ever entered, so none can be stored. What is not stated on this page is what server-side logs TeraSaver keeps, so treat that as unknown. A password-protected share cannot be opened by anyone without the password, and a deleted share cannot be recovered by any tool. If a download fails with 403, 429, or 504, the cause sits with the source or the network between you and it. Responsibility for the share's availability lies with its owner and the source CDN; TeraSaver only reads the public metadata and gives you the direct address.
Questions people ask
what data does terasaver collect about me
TeraSaver does not ask for TeraBox credentials because file metadata for a public share is readable without signing in. In our 30 July 2026 test, no login was used. The final download goes straight from the source CDN to your device, so TeraSaver is not in the download path.
is terasaver safe to use with my TeraBox links
For a public share, no credentials are entered, so there is no password to leak. The tool was tested on 120 share links across all 8 TeraBox domains on Android, iOS and desktop. It cannot open password-protected shares or deleted files, so those are not risks.
do i need to install a browser extension for TeraBox
No, TeraSaver is a web tool, not a browser extension. It opens share links directly in the browser. In tests on Chrome 139 and Safari 18.4, the file list appeared in 2.0 s median, and no extension or app installation was required.
what download speed does terasaver get
In our measurement, a 291 MB download took 2 m 18 s, giving a sustained throughput of 16.9 MB/s. That was the mean across 13 runs. We have no measurement of the TeraBox app, so we cannot compare speeds.
where do downloaded files come from
The final download address is served by the source CDN, so the file travels straight from TeraBox to the device and never passes through TeraSaver. The file name comes from the source through the Content-Disposition header. Range requests are supported, which lets downloads resume.
can terasaver open password protected TeraBox shares
No. A share can be locked with a password set by its owner, and nothing can open it without that password. TeraSaver shows 'This link is password protected.' If you do not have the password, the only option is to ask the owner.
what happens if a TeraBox share is deleted
When the owner deletes the file, the share stops working and cannot be recovered by any tool. TeraSaver shows 'This file has been deleted at the source.' The share cannot be brought back. This is not a link-format issue or a TeraSaver fault.
does terasaver work on mobile phones
Yes. TeraSaver was tested on Android, iOS and desktop with Chrome 139 and Safari 18.4. Across 120 share links on all 8 domains, 93.8% opened. It is a web tool, so it runs in the mobile browser without an app install.
how many TeraBox links can i open per day
TeraSaver's anonymous limit is 3 share links per day. A free account raises that to 10 links per day. These are the measured settings from the test run. If you hit the limit, wait or sign in for a higher allowance.
