Killendar at a glance
Killendar is an open-source desktop calendar for Windows distributed as a single self-contained executable that can be installed or run portably. Appointments are stored locally in one SQLite file within the user profile, optionally encrypted, with no cloud account, sync service, or telemetry involved. For system administrators, the tool is mainly relevant where users need simple, local scheduling without dependency on external services, such as on standalone machines or in privacy-sensitive environments.
As a freeware/open-source project maintained by a single developer, new versions appear irregularly, typically published as version tags with release notes in the associated code repository. There is no guaranteed central update-notification mechanism, so watching the release page is advisable to pick up security and stability fixes in a timely manner.
When updating, administrators should verify that existing portable installations and data directories remain compatible with the new version, particularly the SQLite calendar file (encrypted or not), and consider backing up appointment data before the new executable replaces the previous one.
