None. Lighthouse has no server, no user accounts, and no analytics or tracking of any kind. Everything you customise or record in the app — your settings, your weekly check-ins, your notes — is saved directly in your device's own local browser storage.
All data stays on your device, within the app itself. We never receive it, see it, or have any way to access it. If you delete the app, that data is deleted with it. If you use Lighthouse on more than one device, each device keeps its own separate, independent copy — nothing syncs between them.
Lighthouse does not use any third-party analytics, advertising, or crash-reporting services. No data is sent anywhere, to us or to anyone else.
Lighthouse does not knowingly collect any information from anyone, including children, because it does not collect information from anyone at all.
If this policy ever changes, the updated version will be posted here with a new "last updated" date.
