Frequently asked questions
How do I install an extension in Tableau Desktop?
Download the
.trex file from the extension's page in the catalogue or from My Account. In Tableau Desktop, drag an Extension object onto the worksheet, choose Access Local Extensions, and select the .trex file. Allow the prompt and the extension is ready to use. Each extension's documentation walks through the shelves it takes.How does sign-in in the extension work?
The dashboard author signs in once, from the extension's Format dialog, with the Dataskera account email and password. The licence is then cached locally for 24 hours, so the extension keeps rendering even when Dataskera is unreachable. Viewers never sign in, and viewing a dashboard never triggers a network call.
My Tableau Server or Cloud admin needs to safelist the extension. What URL do I share?
Ask your Tableau Server or Tableau Cloud admin to safelist
https://vizextension.dataskera.com/* with full data access. Every Dataskera extension is served from that host. The three extensions also listed on the Tableau Exchange can be allowed through the Exchange route instead: Waffle Chart, Radial Bar Chart, 3D Scatter Plot.Is it really free on Tableau Desktop?
Yes. Every chart in the catalogue, every feature, on your own machine, with no account to create. The Pro plan is for publishing: when your team shares dashboards on Tableau Server or Tableau Cloud, one yearly price covers up to ten people who build them, and everyone who reads them is included for free. A 30-day Pro trial is available without a card.
What happens when the trial ends, or if we stop paying?
Dashboards you have already published keep working and your readers notice nothing. Tableau Desktop carries on with the whole catalogue, because that is free. Publishing new dashboards to Server or Cloud stops until the plan is renewed. Nothing that is already in front of your audience ever goes blank.
What data does Dataskera collect?
Account data only: email, username, company, role, country, and licence activity. The charts render on the reader's machine and the only network call is the licence check, so no business data ever leaves Tableau. That is a property of the architecture, not a setting. See the Privacy Policy.
Activation failed, or my licence shows as invalid. What should I do?
Check in My Account that the email you typed in the extension is the one on the account, and that the plan is active. The Free plan covers Tableau Desktop only; publishing on Server or Cloud needs Pro or a trial. If it still fails, email support@dataskera.com with your account number (format
DS-000123).How do I export or delete my account data?
In My Account, use the Export my data button to download a JSON archive of everything we store about you, or Delete my account to erase your data permanently within 30 days.
