Every Holon tool installs through Holon Hub — Hub gives each tool its licence and its Canvas access. Add Hub to Canvas once (Settings → Apps → View App Configurations → +App → By URL) with the Hub key, secret and Config URL from your customer portal. Then open Hub → My Tools → Install on the tool. If a tool you bought doesn’t show as licensed, use Already purchased? in Hub and paste your licence key.
Yes. Your portal gives a Config URL for each. In one course (Course Settings → Apps): Hub appears in that course’s menu for the people enrolled in it. Whole account (Admin → Settings → Apps, Canvas admins): Hub appears in the Admin menu, and in courses it starts off — an instructor who wants it turns it on in Course Settings → Navigation. Either way the tools install from inside Hub.
Two likely causes: (1) there's a space before or after the key when you pasted — delete and retype. (2) The license expired or was cancelled — check your portal. If neither, email us the key and we'll look at it.
From your portal, click + Add Tools on your license card. Pick the tools you want — the pro-rated price shows instantly. Pay and they're unlocked immediately under the same license key.
From your portal, click Renew on your license card when it's within 30 days of expiring. Renewal extends your license by 365 days from your current expiration date. Your license key stays the same — no reinstalling needed.
You can cancel any time — cancellation stops auto-renew but your current license keeps working until it expires. Refunds are case-by-case; email us within 30 days of purchase if you need one.
Go to the customer portal, enter the email you used to purchase, and click the magic link we email you. All your license keys are listed there.
All Holon tools work with current Canvas (Instructure). We use standard LTI 1.1. If your Canvas instance has LTI disabled, speak with your IT admin to enable it — it's required for any external tool.
Only what's needed to run the tool. We don't retain student PII after license expiration. Detailed data practices are in each tool's privacy page — email us for a copy before purchasing if you need it for compliance review.
Two ways. (1) Every tool has a live interactive demo at apps.holontechnology.com. (2) Every tool also works for 5 days after install without a valid license — paste any key into Canvas and it runs immediately. After 5 days the license needs to be valid. For longer institutional pilots, email us.
