TSI DEV STUDIO · EDUCATIONAL GUIDE
Privacy, security and practical trade-offs
Local and online models solve different problems. This guide explains what processing location changes—and what it does not—before connecting the principles to all 12 TSI Dev Studio applications.
| Aspect | Local processing | Remote processing |
|---|---|---|
| Data path | Data can remain on the device unless the user exports or backs it up elsewhere. | Data or requests are transmitted to infrastructure operated by a provider. |
| Connectivity | Core work may continue without a connection, depending on the app. | A connection is commonly required for processing, synchronization or access. |
| Accounts | An account may be unnecessary. | Accounts are commonly used for synchronization, sharing and recovery. |
| Backup | The user may need to create, protect and test backups. | The provider may automate remote copies and account-based recovery. |
| Main dependency | Device security, permissions, local storage and backup discipline. | Transport security, account security, provider controls and service availability. |
Offline does not automatically mean encrypted, protected or recoverable. Online does not automatically mean exposed or unsafe. Real protection depends on implementation, permissions, authentication, encryption, backup design, device condition and user choices.
Local-only data can be lost with a damaged, stolen or reset device when no usable backup exists. Connected services can preserve remote copies, but account takeover, provider incidents, retention rules and service closure become part of the risk model.
Consider sensitivity, collaboration needs, number of devices, recovery expectations, permissions and the amount of trust you want to place in a provider. The comparisons below describe trade-offs, not universal winners.
