SlackVault has no paid plan, no trial and no billing of any kind. It is built to run entirely inside free service tiers, which is why the architecture asks you to bring your own Firebase project rather than storing your messages in a database we would have to pay for. That trade is the whole pricing model: you do the setup, and there is no subscription.
Only Google, for your own Firebase project, and only if your usage passes the free-tier limits. SlackVault never sees that relationship and cannot charge you.
There is no paid tier today and none in development. If that ever changes it would be announced on the updates feed rather than applied silently.
The cost is your setup time. You create a Slack app, create a Firebase project and install an extension, which is more work than a hosted product would ask.
