Hi,

Odoo does not offer a special read-only user license. Every internal user requires a paid license, even if their permissions are restricted to view-only access. You can configure groups and security rules to make a user effectively read-only, but they will still count as a licensed user.

If you stop paying for Odoo Online or Odoo.sh, you cannot log in to query information at all. The only options are to export your data before the subscription ends or to restore a backup in the free Odoo Community edition, which you can self-host.

As alternatives, you can set up read-only security groups for internal users, use portal users for external partners (which are free but limited), or keep regular data exports for reference. In short, Odoo does not provide unpaid read-only access; maintaining query access requires either paying for licenses or moving your data to Odoo Community.

Hope it helps

No, no hay licencias de usuario de solo lectura.
