A few useful answers.

LastTime is being built for private personal tracking for adults 18+.

Do I need an account?

No. Guest use starts locally and works offline. Optional identity is for connected features.

Does a scan log a completion?

No. QR and NFC labels open the item. Done now is a separate intentional action.

Does a reading count as maintenance?

No. Readings are independent observations. A usage target needs an explicit completion baseline.

Are reminders safety advice?

No. Targets are chosen by you and local notifications may be delayed or suppressed by Android and device settings. Keep independent arrangements for critical tasks.

Can I recover my records?

The planned encrypted Drive continuity and recovery flow requires setup, consent, a correct account and complete verified objects. An upload alone is not a verified backup.
