    100% local

    Backups are parsed in your browser via a Web Worker. There is no server and no telemetry — privacy is a product property.

    Both real formats

    ZIP and TAR.GZ containers (tgz is Moodle's default since 2.9), with lazy metadata parsing and on-demand content extraction.

    Reads the whole course

    22 of Moodle 5.3's 23 activity modules, plus three Moodle has retired — and the grade items, rubrics and gradebook that sit beside them.

    Tells you when a file names people

    A backup taken with user data carries names, emails and IP addresses. MBZoo says how many people and what kinds of data, before you share the file.

    Safe by design

    Hostile-input posture — sanitized HTML, sandboxed opaque-origin previews, no content execution in the app origin.

    Evidence-driven

    Every durable claim traces to a registered source, experiment or ADR. Machine-validated research indexes.
