Data protection and privacy can be the baseline on a paper tablet because it's where private work lands first. This brief guide explains how privacy protection works on a Viwoods paper tablet: what stays on-device, how access is locked, and how sharing and syncing are handled.
Data Privacy Protection at a Glance
- 128GB local storage: files are stored on-device by default.
- Password + fingerprint locks: apply to device access and individual file locks.
- ViTransfer: transferred files are automatically deleted after 24 hours.
- No proprietary Viwoods cloud: syncing utilizes connected third-party cloud services, such as Google Drive, OneDrive, Dropbox, and Baidu Netdisk.
The Privacy Flow: Create → Lock → Share / Sync → Delete
Create: Local by default
Privacy protection starts at the first save. On a Viwoods writing tablet, notes, notebooks, and imported documents are stored on-device by default in local storage, so a file's normal state is "on this device," not "online somewhere."
It makes the workflow easier to reason about. If a file exists, it exists locally. If it appears elsewhere, that happens through a specific sharing or syncing action rather than an automatic pipeline.
Lock: Control access at two levels
Once files are on the device, the privacy question becomes practical: who can unlock the tablet, and who can open a specific file? Viwoods supports two layers of access control, so protection doesn't have to be all-or-nothing, and everyday use doesn't require treating the entire device as "sensitive all the time."
Device lock: Lock screen password and fingerprint
The first layer protects the tablet itself from casual access, which matters because paper-tablet content often includes personal notes, annotated documents, and work materials.
A lock screen password is set as a 4- or 6-digit numeric code, with options to change or reset it later. Once the password is in place, fingerprint unlock can be enabled. Up to five fingerprints can be saved, and each fingerprint entry can be renamed for clarity.
File lock: Passwords and fingerprints for encrypted files
The second layer applies to selected files. It helps keep sensitive documents protected even when the device is unlocked for normal use, like keeping one folder behind an extra gate.
Passwords for Paper files and Meeting files are managed independently, although identical passwords may be set. File passwords must be 4–12 characters in length. Fingerprint access for encrypted files is also supported and can be enabled manually under [Settings] – [Security] – [Fingerprint].
Share / Sync: Moving files beyond the device
After creation and locks, privacy protection becomes a question of movement. Sharing and syncing can both take files beyond a single device, but they serve different purposes and follow different rules.
Sharing is usually time-bound and task-based. Syncing is ongoing and continuity-based, designed for cross-device availability.
Share via ViTransfer: Temporary by design
ViTransfer is designed for transfers that shouldn't linger, with transferred files automatically deleted after 24 hours. This time limit reduces the chance that older transfers remain available longer than intended, and it reflects how sharing typically works in practice, where a transfer serves a specific moment rather than acting as permanent storage.
Sync via third-party cloud: Cross-device continuity
Syncing supports cross-device access over time. Viwoods doesn't run a proprietary cloud, so syncing uses third-party cloud platforms. When syncing is enabled, a copy of the file is stored in the connected cloud service to make it appear on other devices, while the on-device copy remains stored locally. Privacy controls and retention for the cloud copy follow the cloud platform and the account settings used there.

Delete: What gets removed, where, and when
Deletion is where privacy rules show up in practice, with different removal behavior depending on where a copy exists.
- ViTransfer: transferred files are automatically deleted after 24 hours, so the transfer channel doesn't become a long-term storage.
- On-device files: Files remain in local storage until they are manually removed.
- Third-party cloud sync: deletion and retention follow the connected cloud platform's behavior and settings.
Taken together, the flow remains consistent: create locally, secure access with locks, move files through sharing or syncing when needed, and define retention up front so sharing stays temporary instead of drifting into an indefinite archive.
FAQs
Q1: Do my notes upload automatically?
No. Notes and documents are stored on-device by default. Uploading only occurs when sharing is initiated or when syncing is enabled through a connected third-party cloud service.
Q2: Is there a Viwoods cloud account that must be used?
No. Viwoods doesn't provide a proprietary cloud for storage or sync, so a Viwoods cloud account is not required for keeping or syncing files. A Viwoods account login is only required to use ViTransfer.
Q3: Can Viwoods be used fully offline?
Yes. Reading and writing work offline with files kept in local storage. An internet connection is only needed when using features that move data off-device, such as ViTransfer or cloud syncing.
Q4: What's the difference between locking the device and locking a file?
Device locking controls who can access the tablet. File locking adds a second layer on selected documents, so those files still require authentication even after the tablet is unlocked.
Q5: How long do ViTransfer files stay available?
ViTransfer is time-limited by design. Transferred files are automatically deleted after 24 hours.
Q6: If syncing uses Google Drive or Dropbox, who controls privacy and retention?
When files are synced to services like Google Drive or Dropbox, the cloud version is governed by that service's own privacy and retention settings under the signed-in account.
Conclusion
Data protection and privacy on a Viwoods paper tablet follow a simple promise: files stay local by default, access can be locked at both the device and file level, ViTransfer sharing is time-limited, and syncing runs through third-party cloud platforms. That keeps privacy decisions visible and intentional, which is exactly what a paper-first workflow should feel like.
