Reversibility export

Retrieve all of your data, in a single operation, in an open format readable without Polyodos — independent of any storage location or legal retention obligation.

Not a project export

Two exports meet two different needs — do not confuse them:

Export	Scope	Who, when
Download project (Export / Import)	A single project	Sharing a study, migrating between two instances
Reversibility export (this page)	All your owned projects, at once	Retrieving your data, including if you leave the service

Where to find it

My account → Reversibility export section → Download my data button.

What the archive contains

A ZIP file containing:

• one .json file per project you own (context, analysis, action plan — all study data, across every module), in a readable, documented format;
• for each method family, the library delta: only the items you added or modified compared with the default catalogues (the catalogues themselves are not duplicated — see the ownership clause in the terms of service);
• a _manifeste.json file summarising the exported projects;
• if applicable, an _erreurs.json file if a project could not be opened.

A progress bar shows project-by-project progress — the operation can take several minutes on an account with many projects.

Your owned projects only

Only projects you own are included. A project shared with you for reading or editing is not included — ask its owner to export it, or to transfer ownership to you (see Sharing a project).

What to do with the file

Each project's JSON can be re-imported via Export / Import on another instance or account. Keep it as proof of reversibility, independent of the service's future availability.
