Lokus is a local-first application. Your notes, files, and calendar data live on your device. We do not run servers that store your documents, we do not sell data, and we do not use your content for advertising or to train AI models.
Everything you create in Lokus — notes, tasks, canvases, kanban boards, and synced calendar events — is stored in files and a local database on your own computer. Deleting the app or your workspace deletes that data.
If you choose to connect Google Calendar, Lokus requests the following scopes: read-only access to your calendar list and events (calendar.readonly), the ability to create and edit events (calendar.events), and your email address (userinfo.email) to label the connected account.
Calendar data retrieved from Google is stored only in a local database on your device so your calendar loads instantly and works offline. It is never transmitted to Lokus servers (we don't have any that receive it), never shared with third parties, never sold, and never used for advertising or model training. OAuth tokens are stored in your operating system's secure keychain.
Lokus's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
You can disconnect a Google account at any time from Preferences → Connections inside Lokus, which deletes its locally stored events and tokens. You can also revoke Lokus's access from your Google Account permissions page.
The same rules apply to Microsoft, iCloud/CalDAV, Notion, and iCal calendar connections: credentials go in your system keychain, fetched data stays in the local database on your device, and disconnecting removes it.
If you create a Lokus account on this website, we store the email address and authentication details needed to operate it. Payments, when offered, are processed by our payment provider; we never see or store card numbers.
The Lokus desktop app does not track you. Optional crash reports, if enabled, contain technical error details only — never your notes or calendar contents.
