01 / The correction desk

Current truth is not the whole record.

Calendars are operational data. Meetings move, providers go offline, and yesterday’s useful plan quietly disappears beneath today’s sync.

Snapshotter keeps encrypted local editions and compares each against the last. A cancelled appointment is shown with its former time; a moved one keeps the earlier form ready for export.

The two-minute recovery route

Record. Compare. Recover.

  1. 01

    Take an edition

    Import any ICS file for free, or connect a CalDAV collection for scheduled capture while the app runs.

  2. 02

    Read the change desk

    Added, moved, and cancelled events appear as a quiet ledger—not a wall of calendar markup.

  3. 03

    Export only what matters

    Select one or several earlier events. Snapshotter builds a timezone-aware ICS file any calendar can import.

A private archive, not another provider

The calendar stays yours.
