Private snapshots instead of a generic cloud folder
Booky's cloud backup is not a mandatory part of the app. It is an intentional add-on for users who want an off-device restore option. The feature uses the app's private Google Drive appData area.
Google Drive appData
For optional backup, Booky intentionally does not use a visible standard folder, but the app's private Drive area.
Flow
How the flow works
The cloud feature is intentionally reduced to a small, private flow so it stays understandable and predictable.
Use Google only for the backup feature
When the feature is enabled, the user selects a Google account and authorizes only the appData access Booky needs.
Booky writes a private snapshot to appData
This can contain library and wishlist data, relevant cover files, and snapshot metadata needed for restore and status display.
The known cloud state can be loaded from inside the app
Users can inspect the available cloud state and restore it without manually browsing Drive folders.
Guardrails
Important guardrails
The cloud feature is intentionally bounded so it stays understandable and never turns into a hidden requirement.
Cloud backup is optional and can be turned off in the app at any time.
Booky does not receive account name or email address in this authorization flow.
Snapshots are stored in the private appData area, not in a visible standard folder.
Local backups and exports remain available even without cloud backup.
FAQ
Cloud FAQ
For a public product website, it matters to address the main misunderstandings early: cloud is optional, private, and limited in scope.
What does Booky store in the cloud?
Depending on use, this can include library and wishlist data, relevant cover files, and snapshot metadata such as book count, generation time, app version, and device name.
Does disabling the feature automatically delete my existing cloud data?
No. Disabling the feature stops future uploads. It does not automatically remove a snapshot that is already stored in your Google account.
Does Booky need additional Google data like my email address?
No. In this authorization flow Google does not provide Booky with the account name or email address.
Can I use Booky meaningfully without cloud backup?
Yes. The app is designed local-first. Cloud backup is an extra option for users who want an additional external restore path.
