Your preparation data stays in your browser.
Leet Progress is designed without a cloud user database. The website and extension keep progress, target companies, interview plans, revision state, notes and personal analytics locally in the browser profile.
May be fetched remotely
- Public company/problem catalog
- Catalog version and checksum
- Application assets and normal website resources
Not used for user data
- chrome.storage.sync

Local website ↔ extension sync
- Same browser profile only
- Exact Leet Progress origin bridge
- Versioned idempotent mutations
- No whole-state cloud synchronization
Device changes
Because personal data is intentionally not cloud-synced, a different browser profile or device does not automatically receive your progress. Portable local backup/import is the supported migration path.
