Every editable thing in a project keeps a complete, retrievable history. When someone changes a layer, edits a sketch, or replaces a file, the prior state is captured, and a project owner, admin or manager can view it on a timeline and restore any earlier version.
History for every stored feature
Geometry edits and attribute changes, feature-by-feature.
Every shape, label and style revision on a drawing.
Saved distance / area shapes and their recorded values.
Georeferencing: corners, bounds, rotation and opacity.
Basemap definitions and styling presets.
Form schema versions and the responses tied to each.
Replaced uploads, recoverable to any prior copy.
A whole-project restore point across all of the above.
How it protects your data
Each save appends a revision. Past states are never overwritten or silently lost.
Roll a single feature, or the whole project, back to exactly how it was at any captured moment.
Restores are limited to project owners, admins and managers. Editors and viewers cannot rewrite shared history.
Revisions are encrypted at rest, and every restore is written to the project audit log with who, what and when.
