Where is my data stored?

Licensing and Pricing

How much does it cost?
View the licensing options.

Do I get updates as you make improvements?
When you purchase a license, you are entitled to one year of product updates and support. After the first year, you may purchase an additional year of support and updates for 50% of the original purchase price.

When does my software maintenance start?
Our policy is consistent with Atlassian's.

• New license purchase: Your 12 month software maintenance period will commence from the date of payment confirmation.
• Upgrade: Your 12 month software maintenance will commence from the date of payment confirmation and replaces any active software maintenance of the upgraded license.
• Software maintenance renewal: Your 12 month software maintenance will commence from the expiration date of the previous maintenance period, regardless of when the maintenance renewal was purchased.

Do I need an additional license for each CPU running Confluence, or each Confluence installation?
Pricing is on a per node basis. For example, if you have two installations of Confluence, and you wish to run the Gliffy Plugin for Confluence in both, you need to purchase two licenses. If you plan to run clustered Confluence, you need to purchase additional node licenses from us.

What kind of support do you offer?
With standard support, we respond to email questions within a few hours, Monday through Friday, 9am-5pm Pacific Time. Users can also reference How Do I's, Tips, Forums, Gliffy FAQs, and Gliffy Plugin for Confluence Troubleshooting FAQs anytime.

I have a 500-user Confluence license, but I believe only 25 users will run Gliffy. Can I get a 25-user Gliffy license?
To keep things simple, a Gliffy license needs to match the license you have for Confluence. That's because our customers tell us that many more people than they expect end up creating Gliffy diagrams in Confluence. Also, restricting Gliffy to a subset of Confluence users puts more administrative burden on you.

Can I try the Plugin before I buy it?
Yes. When you download and install the Plugin, a 45-day free trial is automatically initiated.

What happens when the free trial ends?
You will still be able to edit and view any diagrams that have already been created. However, you may not create additional diagrams without purchasing a license.

Where do I enter the Gliffy license information?
You must have Administrator access to Confluence to enter license information. You will find the Gliffy License page by browsing to Administration>Gliffy Plugin Admin.

We would like to use Gliffy for our Open Source Project. How do I get a license?
Gliffy proudly supports the open source community and offers a free license for qualified Open Source Projects.

How does Gliffy's Pricing Compare to Traditional Software?
Compare For Yourself Gliffy delivers cost-effective diagramming to your entire team. Gliffy Plugin for Confluence licenses are good for one year. After one year, you can renew your license at a discounted rate. Our licenses are significantly more cost effective than other leading diagramming applications.

Link to diagrams attached to other pages?
To link to diagrams that were originally created on another page, you must specify the space key and original page name in the {gliffy} tag. For example: {gliffy:name=my diagram|space=ds|page=A great new way to share ideas|align=left|size=L}. If you've been creating your diagrams with the Add Diagram link, all of this information will already be in the {gliffy} tag, and you can simply copy and paste it.

Remove the Add Diagram link?
You must have Administrative access to remove the Add Diagram link. On the Administration>Plugins page, select Gliffy Plugin. Disable the module with the title - "Web Item to show Add Diagram link".

You will find in depth documentation for using the Gliffy Confluence Plugin in our Gliffy User Manual.

Technical Troubleshooting for Gliffy Plugin for Confluence

I recently upgraded to a new version of the Gliffy Plugin, and now all my diagrams show up as broken images.
Try restarting Confluence. That should complete the upgrade and fix the problem.

Why don't diagram names work when they have extended Unicode characters?
Chances are you need to configure your application server to encode URI's using UTF-8. See this tech note from Atlassian on the subject. Follow this forum thread for more information regarding Unicode issues in the Plugin. We think all Unicode issues have been fixed as of version 1.2.0, contact us if your think otherwise

I tried to install the Gliffy Plugin for Confluence using the repository client, and I get a strange error message.
Check your Confluence error log for clues. It's probably something easy to fix. If you're running MySQL, see the next FAQ entry for another common issue.

I'm running MySQL, and I get a com.mysql.jdbc.PacketTooBigException or "There was a problem evicting or flushing a PluginData object" error.
As of Confluence 2.3, Plugins are stored in the database. By default, MySQL has a maximum packet size that is smaller than the size of the Gliffy Plugin. To resolve this issue, you'll need to set max_allowed_packet = 16M in MySQL. Search Google for more on how to fix this.

I'm upgrading to a new version of the Plugin, and everything seems broken.
Restart Confluence after upgrading the Gliffy Plugin. If you're running a Confluence cluster, you will need to uninstall the old Plugin on each node, one at a time, by accessing each node directly. After uninstalling, restart each node of the cluster, and install the new version of the Plugin.
