How long will the private beta be free?
Early users who join during our private beta will get lifetime free access to Zinnias.io. Once we launch publicly, we'll introduce paid plans, but beta users will keep their free access.
How secure is Git access?
Very secure. We don't have direct repo access. We give you the command to run to summarize git history preventing us from seeing your source code.
How do you handle data privacy?
We take data privacy seriously. All data is encrypted in transit and at rest.
Can I customize the review templates?
Yes! While we provide battle-tested templates out of the box, you can customize them to match your organization's review process and competency framework.
How far back does the work history go?
By default, we analyze the last 6 months of activity, which covers most review cycles. You can adjust this timeframe based on your needs.
Can I export the review data?
Yes, you can export reviews and performance data in various formats (PDF, Word, HTML) for easy sharing or record-keeping.
