RESEARCH
Personalization should not require unnecessary data collection.
A privacy model for saved calculations, local storage, accounts, workspaces, analytics, exports, synchronization, retention, and deletion.
Start with local-first options
Where practical, recent tools, favorites, and draft calculations can remain in the browser without creating an account.
Collect only what the feature needs
Do not request identity, income, account numbers, precise location, or sensitive documents unless essential to a clearly explained function.
Separate analytics from workspace data
Product analytics should use the least detailed events practical and should not expose personal calculation inputs unnecessarily.
Explain synchronization
If cloud accounts are introduced, users should understand what is uploaded, how it is protected, and how to delete or export it.
Set retention rules
Saved projects, abandoned drafts, logs, backups, and support records should have defined retention and deletion practices.
Design for revocation
Consent changes and account deletion should propagate through relevant systems without requiring avoidable support intervention.
