VIP-only feature
Connected by the file lifecycle
The products work together because the file does not stop after upload.
A document may begin in cloud storage, become a note attachment, be sent through file transfer, collected from others or moved into Private Space. OKPAN keeps these actions inside one workspace.
The same account manages files, notes, sharing traffic, transfer quota, distribution points and privacy benefits.
Choose by goal
Start from the result you want, not from the product name.
Transfer directly between two devices
Use Online Transfer when two devices need to exchange files directly through their browsers, without first creating a long-term cloud file.
Choose Online Transfer →Store and protect important files
Use Cloud Storage for personal archives, team materials, photos, videos and documents that need to remain available. Move identity documents, certificates, financial records and other sensitive files into Private Space, where they remain visible only to you.
Send a large file quickly
Use File Transfer when the file is temporary, the recipient needs a direct link and long-term storage is not the main goal.
Choose File Transfer →Build structured knowledge
Use Cloud Notes for long-form content, research, project records, images, attachments and files already stored in My Cloud.
Choose Cloud Notes →Receive files from many people
Use File Collection when customers, classmates or team members need to submit files into the same destination folder.
Choose File Collection →Publish a private test build
Use App Distribution to publish APK or IPA packages, generate an installation page and share it with selected testers.
Choose App Distribution →Free before expansion

Common questions
Understanding how the OKPAN products fit together.
No. Cloud storage, file transfer, notes, sticky notes, file collection, app distribution and Private Space are managed under the same OKPAN account.
Use Cloud Storage for files that need long-term organization, preview and sharing. File Transfer is better for temporary delivery.
Cloud Notes supports long-form content, notebooks, tags, images, attachments and cloud-file insertion. Sticky Notes remains a pure-text tool for short ideas, reminders and checklists.
When a collection link is created, the owner selects a destination folder. Contributor uploads are saved directly into that cloud-drive folder.
No. Private Space is a VIP feature that shares the same total capacity as the main cloud drive. It changes the privacy boundary, not the capacity pool.
Yes. Cloud Notes can reference files already stored in My Cloud, so the same file does not need to be uploaded again.
The core services include free basic benefits. Paid expansion is used for more capacity, traffic, transfer quota, app-distribution points, larger package uploads or VIP privacy benefits.
Open the Service Benefits page to compare cloud capacity, file-transfer quota, VIP membership, sharing traffic packs, distribution points, upload-space membership and account balance.
