Terms · Effective 12 October 2026
The terms, in plain words.
What you can expect from us, and what we ask of you in return.
These terms are the deal between you and us for using our sites and the Klatos app. By using them, or by creating an account when the app opens, you agree to them. If you don't agree, don't use them. How we handle your data is a separate page: the privacy notice.
1. What these terms cover
These terms apply to everything Vixoris runs:
- vixoris.com — the company site and its writing.
- klatos.vixoris.com — the Klatos site, manifesto and essays.
- waitlist.klatos.app — the Klatos waitlist and its contact form.
- klatos.app — the Klatos application, and id.vixoris.com, its sign-in. These are not open yet; the parts below about the app apply from the day it opens. Until then, klatos.app forwards to the waitlist.
- learn.vixoris.com — Vixoris Learn, our course site, and its contact form. It is not open yet; the parts below about it apply from the day it opens.

3. Your account
The Klatos app requires an account. To have one you must be at least 15. The sites are free to read and need no account for now — that may change for the blog. On Vixoris Learn, the home page and the contact form need no account; reading the lessons does, and signing in keeps your place and your results. Keep your sign-in to yourself: you are responsible for what happens under your account. Make sure the details of your account stay up to date.
4. The waitlist
Joining the waitlist means one thing: we email you when Klatos opens. It is free, it creates no obligation on your side, and it is not a purchase, a pre-order or a promise of a launch date or a feature set. Klatos ships when it is ready.
Your place is confirmed by the link we email you, and only by that click. Whatever the waitlist says you have earned — your place in line, your referral count, the Founding Member badge if you are among the first 500 to confirm — is yours as described there. Referral links are for sharing with people you know. You can leave any time: unsubscribe from any email, or delete your record from the unsubscribe page. Deletion is immediate and final.
5. Subscriptions and billing
Klatos has a free plan and a paid one. If you take the paid plan, you pay on a recurring basis — monthly or yearly, whichever you pick — and it renews until you cancel. The price, and any free trial, are shown before you pay.
You can cancel any time from your account. Cancelling stops the next renewal; you keep the paid plan until the period you have already paid for runs out. We don't give refunds for time left in a period, except where the law requires one. Payment is handled by Stripe; your card details go to Stripe, never to us.
Founding Member status, and any perk tied to it, belongs to your account. It isn't transferable, and it doesn't survive deleting the account.
6. Your data is yours
Everything you put into Klatos — your habits, check-ins, notes, reflections, the numbers you track — is yours. You give us only the permission we need to run the app for you: to store your record, process it and show it back to you. Nothing more. We don't claim ownership of it, and we don't use it for anything but running Klatos for you.
You can export your whole record from the app any time, free, as JSON or CSV. When you delete your account, your record goes too — see the privacy notice for exactly how and when.
If we ever decide to stop running Klatos, you will hear it from us first: we email you at least three months before it closes. Export stays open for that whole time, free, on every plan, so you can leave with your whole record.
7. Using it fairly
We ask the obvious. Don't:
- mistreat other people on Klatos — no violence, no harassment of any kind;
- attack, overload or interfere with the sites, the app or the servers behind them;
- scrape or hit them with bots or scripts without our written say-so, or at a pace that hurts other people;
- take the software apart to lift its code or the way Habit Strength is calculated;
- send malicious code, or feed the forms with addresses that aren't yours;
- pretend to be us, or use our names to suggest we made or backed something we didn't.
The sign-up and contact forms are rate-limited. If you hit the limit, wait a little and try again.
8. Our content and our names
The software, the design, the writing and the way Habit Strength is calculated belong to Vixoris and are protected by copyright. You can read the sites, link to them, quote a passage with attribution. However, you are not allowed to republish them whole or pass them off as your own.
Vixoris and Klatos, with their marks and logos, are the names of our company and our product. They are ours.
Keycloak™ is a trademark of the Linux Foundation. Vixoris Learn is independent and not endorsed by the Keycloak project.
9. Links to other places
Our pages sometimes link out to tools we use, to Google Fonts or other external links. Those sites have their own terms and their own privacy practices, and we don't control them.
10. What we don't promise
We work to keep the sites and the app accurate and available, and we say so on the page when something isn't ready. But they are provided as they are and as available: we can't guarantee they will always be up, or free of mistakes, and we may change or take down any feature or page at any time, except the export and the notice promised in section 6. Klatos helps you keep a record and see it clearly; it can't promise any particular result in your own life.
To the extent French law allows, we aren't liable for indirect loss, or for loss that comes from relying on the sites or the app, or from being unable to reach them. Nothing here limits liability that the law says cannot be limited, including your rights as a consumer.
11. Ending it
You can stop any time: leave the waitlist, or delete your account and stop using the app. We can suspend or close an account that breaks these terms, abuses the service or is used for fraud or any unlawful activity. And we may close any account at our own discretion, without notice.
12. Law and disputes
These terms are governed by French law. If something goes wrong, write to us first — a real person answers, and most things resolve in a message or two. Failing that, the French courts have jurisdiction. If you are a consumer living elsewhere in the European Union, you keep the protections of your own country's law.
13. Changes
When these terms change, this page changes and the date at the top moves. For a change that materially affects your account, we email you before it takes effect. Keep using the sites or the app after a change, and the new terms apply. We don't move the date for wording alone.
