Share permissions and expiry
How permission toggles and expiration dates work on share links.
Each share link has its own set of permission toggles and an optional expiration date. The settings are independent across links, you can have a tightly-scoped supplier link and an open evergreen customer link on the same project.
The permissions
| Permission | Default | What it controls |
|---|---|---|
| Read project | Always on | Can the viewer see the project at all? Implied by the link existing. |
| Allow Excel download | Off | Can the viewer download the Miivo workbook export? |
There's no per-sheet or per-unit permission. A share link gives access to the whole project (minus sheets marked not-customer-shown).
Expiration
Links can be evergreen (never expire) or time-limited (stop working after a chosen date).
| When… | Use… |
|---|---|
| Customer has ongoing access for the build's duration | Evergreen, revoked at finalisation. |
| Supplier needs a brief look | Time-limited (a few days to a week). |
| External reviewer for a single decision | Time-limited (24-48 hours). |
After expiration, viewers see a link expired page. The link itself isn't deleted, just inactive. You can extend an expired link by editing it.
Editing a link
Open the project's Share screen.
Find the link in the list and click its menu.
Choose Edit.
Adjust permissions or expiration; save.
Changes apply immediately. Anyone with the link sees the new permissions on their next page load.
Why no per-person permissions
Share links are intentionally simple. They're meant for ad-hoc external sharing, for ongoing collaboration with someone, invite them as a workspace member instead.
Audit
Every link creation, edit, and revocation is logged in the audit log along with the link's permissions at that moment.
