Teamviewer is such a scummy company.

• If you sign up for a TeamViewer license, you have 7 days to cancel and get a refund. This does not apply to renewals.
• Licenses are only available in annual installments.
• TeamViewer’s license recommendation tool may suggest a license that is greater than your actual need. In my case, the cheaper license that best fit my business use case (one session at a time) was not presented during onboarding.
• TeamViewer does not offer mid-term downgrades, but does allow mid-term upgrades.
• You will get a renewal notice 30 days before renewal. TeamViewer requires written notice of cancellation 28 or more days before renewal.
• TeamViewer does not offer the option for mid-term cancellations and will not grant a prorated refund for the remainder of your unused license time. When you cancel, you are only cancelling the next renewal.

We got totally boned when our renewal notice went out just before a three day weekend. PayPal and our bank sided with TeamViewer. Apparently, someone tried to sue over this shady practice in California and the court also sided with TeamViewer. Probably would have dodged this bullet if I had thought to scroll through the TeamViewer subreddit, I went with them because I had positive experiences using the free version for personal use.

Been using RustDesk for years with great success. I especially appreciate the responsible disclosure banners on the main site and GitHub warning users that they might be on the phone with a scam artist.

IMO, all the proprietary remote access software (Teamviewer, Ultraviewer, Anydesk, Etc) companies are profiting from and therefore complicit in the use of their software to scam people.
