Terms of service
Last updated: 28 October 2026
Alphonsus is a time blocking calendar made and run by me, Nathaniel Arnold, as an individual. By using Alphonsus, you agree to these terms. If anything here is unclear, write to me at nxthaniel@alphonsus.io.
The short version
Alphonsus is beta software. Use it, enjoy it, and keep your own backups. Your calendar stays yours. If you buy and change your mind within 30 days, I will refund you.
Who can use it
You need to be at least 13 to use Alphonsus.
Your account
You sign in at app.alphonsus.io with your email address. Keep access to that email safe, because anyone who can read it can sign in as you. You are responsible for what happens in your account.
The free beta
Alphonsus is free to use during the beta. Free beta use ends when the desktop app ships. I will email you at least 30 days before that happens. Free accounts are deleted 30 days after the beta ends, unless you buy Alphonsus.
Buying Alphonsus
The Æternus lifetime offer is a one time purchase of $40, sold through Gumroad. It includes the app for life, plus MAGNUS features for life. MAGNUS is otherwise $10 a month or $100 a year. The lifetime offer ends when the desktop app ships.
"For life" means for as long as I run Alphonsus. If Alphonsus ever shuts down, I will give you at least 90 days' notice, so you have time to export everything with /export.
Gumroad handles payment, and its own terms apply to the transaction. Prices are in US dollars. Gumroad handles any sales tax.
Refunds
You can get a full refund within 30 days of purchase, no questions asked. The details are in the refund policy.
Your content stays yours
Everything you put into Alphonsus belongs to you. You give me only the permission I need to store it, sync it across your devices, and show it back to you. I don't claim anything more. How I handle your data is set out in the privacy policy.
Fair use
Don't:
- break the law with Alphonsus, or use it to harm anyone
- try to get into accounts or data that aren't yours
- probe, overload or disrupt the service, or get around its limits
- copy, resell or rebuild Alphonsus as your own product
- share your license key or account with others
Beta software
Alphonsus is still being built. Things may break, and data could be lost. Keep your own backups by typing /export in the command bar from time to time.
Changes to Alphonsus
I may add, change or remove features as Alphonsus grows. Some features cost me money to run, such as place search, so I may set fair limits on how much free accounts can use them. If you bought the lifetime offer, you keep what you paid for.
Ending things
You can stop using Alphonsus and delete your account at any time, in the app itself: type /deleteaccount in the command bar, or use the Danger section in :settings. That deletes everything, including any files you attached. I may suspend or close an account that breaks these terms. Where I can, I will tell you first and give you a chance to export your data. If I close your paid account for no fault of yours, I will refund you.
No guarantees
I build Alphonsus with care, but I provide it as it is, without promises that it will always be available, error free, or right for your needs.
Limits on my liability
As far as the law allows, I am not responsible for missed meetings, missed flights, lost data, or other indirect losses that come from using Alphonsus. If I am found responsible for anything, the most I owe you is what you paid me in the 12 months before the claim, or $40, whichever is more. Nothing here limits rights you have under law that cannot be limited.
Changes to these terms
If these terms change, I will update this page and let you know by email. If you keep using Alphonsus after that, the new terms apply.
The law
These terms are governed by the laws of the State of New York, USA, and disputes go to the courts of New York.
