Gameplay and saved puzzles
- Use Back inside a puzzle to save and return Home.
- Open Continue puzzle on Home to resume the latest compatible campaign save.
- Daily saves are tied to their date and do not replace campaign progress.
- If a puzzle behaves unexpectedly, close and reopen the app before clearing storage. Local recovery copies may repair a damaged player document automatically.
Purchases and access
Use Restore purchases from the access screen when a qualifying purchase is missing. Confirm that the device uses the same Apple or Google store account that made the purchase. Store billing, cancellation, refund, and pending-payment status are controlled by Apple or Google.
Deleting a Lumina account does not cancel a store subscription. Manage active subscriptions in your Apple or Google account.
Accounts and cloud backup
Guest play does not require an account. When configured, Profile shows the current account and backup state. A pending or offline status keeps local progress available and retries safely. A conflict review shows only settings that differ; puzzle progress and ownership are merged without silently enabling analytics, diagnostics, or cellular downloads.
Create a privacy-safe support report
In Settings, choose Create support report and review the disclosure. The report contains technical and aggregate state only. It excludes your name, email, account ID, puzzle contents, saved board, tokens, secrets, paths, and raw error messages. Nothing is sent until you choose a recipient in the system share sheet.
Account access and deletion
Signed-in players can export or permanently delete configured cloud account data from Profile. For instructions and the off-device request route, visit Delete your account.
