1. Publisher, scope and acceptance
rulix calc is published by Damien Hottelier, Switzerland. These terms apply to calc.rulix.ch, its associated account and sharing services, and the rulix calc iOS app.
By using the service after these terms are displayed, or by checking acceptance during sign-in, you accept the current version. If you do not accept required terms, do not use the relevant features. Mandatory consumer protections always remain unaffected.
2. Local service and optional account
The iOS calculator and its main local features work without an account. An optional account lets you synchronize sheets, collaborate with authorized people and manage a subscription purchased on the web.
You must provide an email address you control, protect sign-in links and notify us promptly of unauthorized access. You are responsible for people invited to your teams and their permissions. A person without the required legal capacity must obtain permission from their legal representative.
3. Calculations, external data and Intelligence
rulix calc helps write, evaluate and present calculations. Results, conversions, rates, dates, templates, recognized captures and generated drafts can be wrong or unsuitable for your circumstances. Always verify inputs, units, assumptions, sources and results.
The service does not provide financial, tax, legal, medical, accounting or professional advice. You remain responsible for decisions based on a result. External rates are shown with their source and date when available and are not executable quotes.
On compatible devices, Apple Intelligence can propose an on-device draft. It is a suggestion clearly separated from the result checked by the engine and must only be inserted after your confirmation.
4. Your content, cloud storage and shared links
You retain your rights in sheet content. You grant only the technical permissions needed to store, synchronize, convert, export or share that content according to the actions you request.
Only upload content you are allowed to process and share. An “unlisted” copy is not confidential: anyone with its link can read it. Do not place secrets, sensitive data or unlawfully distributed content in such a copy.
Account deletion and the treatment of local, cloud and public data are described in the privacy policy. Export anything you want to keep before deletion.
5. Acceptable use and intellectual property
Do not bypass security, disrupt the service, automate abusive requests, introduce malicious code, impersonate another person, infringe third-party rights or use the service unlawfully.
The rulix calc name, interface and original components remain protected by applicable rights. Open-source components retain their respective licenses, identified in the project notices. These terms transfer no rights in a trademark or third-party content.
6. Web subscriptions and no in-app purchases
Any paid plan is purchased only on the web. Price, currency, billing interval, seats and applicable taxes are shown before confirmation in the Stripe checkout flow. A subscription renews at the displayed interval until cancelled from the dashboard or billing portal.
Fees already due are refundable only where the offer, applicable law or an express decision requires it. Mandatory cancellation, withdrawal, refund and order-correction rights always prevail over this clause.
The iOS app contains no in-app purchase, price, subscription button or invitation to buy on the web. An existing account may only reflect web-service entitlements.
7. Availability, changes and ending the service
We aim to keep the service reliable but do not guarantee uninterrupted availability or freedom from defects. Features may change for security, compatibility, compliance or product improvement. Local features remain distinct from network services.
We may suspend access because of a security risk, abuse, a serious breach or a legal requirement. Where reasonably possible, we will allow data export before a non-urgent closure. You may stop using the service and delete your account at any time, subject to transferring shared-team ownership first.
8. Warranties and liability
To the extent permitted by law, rulix calc is provided “as is”, without any guarantee of a particular result, fitness for a particular purpose or freedom from error. Nothing excludes liability that the law does not allow us to exclude, including intentional misconduct and mandatory consumer protections.
In other cases, liability is limited to reasonably foreseeable direct loss caused by a proven breach. To the extent permitted by law, we are not responsible for loss caused by incorrect input, an unverified result, disclosure of a shared link or a third-party service outside our control.
9. Governing law, contact and changes
Swiss law applies without depriving consumers of mandatory protections or courts available in their country of residence. Before starting proceedings, you may contact us to seek an amicable solution.
These terms may be updated when the service or applicable law changes. A material change will be communicated appropriately and may require renewed acceptance. The date above identifies the current version.
