Terms of Service

Provider - IT Maciej Bodnar, operator of the Cerium platform (also operating under the fire-gem brand).

Client - natural or legal person (a school) who entered into an electronic services agreement with the Provider.

User - natural person using the Platform via an account created by the Client (e.g., teacher, student, parent), or the Client using the Platform personally.

Platform - the Cerium system at cerium-app.com, used to manage language schools, music schools and tutoring.

Account - User's individual access to the Platform, secured by login and password.

Subscription - paid use of the Platform under one of the plans (Pro, School, Enterprise).

Tenant - separate data instance within the Platform, assigned to one organization (school).

These Terms constitute the regulations within the meaning of art. 8 of the Polish Act on Provision of Electronic Services dated July 18, 2002.

Use of the Platform requires acceptance of these Terms.

The Provider reserves the right to amend the Terms with 14 days' notice; changes may not infringe acquired rights. A Client who does not accept the changes may terminate the agreement before they take effect - until that day the previous Terms apply.

Technical requirements: modern browser (Chrome, Firefox, Safari, Edge - latest 2 versions), active internet connection, JavaScript and cookies enabled.

There is no self-service registration on the Platform. The B2B client (school) account is created by the Provider after a contract is concluded. End-user accounts (teachers, students, parents - B2C clients) are created by the school within its panel.

When the school account is created, the following are provided: school name, contact details (email, phone), VAT ID (if applicable). End-user account data is entered by the school.

The User undertakes to provide truthful data and keep it up to date.

Passwords are stored encrypted (bcrypt). The Provider has no access to plain-text passwords.

An Account may be blocked for breach of these Terms - with a 7-day cure-period notice.

Use of the Platform is paid per the pricing at cerium-app.com/pricing.

The first 14 days are free (trial period), no card required.

Payments are processed by Stripe Payments Europe Ltd. (1 Grand Canal Street Lower, Dublin 2, Ireland). Cerium uses Stripe Connect - course payments go directly to the school's account; Stripe fees per their pricing.

Subscriptions auto-renew. The Client can cancel anytime in the panel - cancellation takes effect at the end of the paid period.

VAT invoices are issued automatically and available in the Client's panel.

Failure to pay results in suspension after 7 days. After 30 days the account is archived (data retained for 90 days before permanent deletion).

The Platform is provided in the SaaS model - the User does not receive a copy of the software.

Each tenant has a separate data space. The Provider guarantees tenant isolation.

The Client (school) is the data controller of its students', parents' and teachers' personal data within the meaning of GDPR. The Provider acts as processor - see Privacy Policy and DPA.

Technical limits (students, users, file storage) depend on the plan - see pricing. The pricing may provide for paid overage of the student or teacher limit: a monthly surcharge per additional active student or teacher above the plan limit, added to the invoice. Data entered into the Platform remains accessible regardless of exceeded limits.

The User undertakes not to introduce illegal, immoral, or spam content.

Cerium does not monitor lesson content or User materials - except as required by lawful requests of competent authorities.

Complaints should be sent to [email protected] or via the panel form (Support).

A complaint should include: User's data, problem description, expected resolution.

The Provider examines complaints within 14 days of receipt.

No reply within this period means the complaint is upheld.

A consumer (natural person not engaged in business activity) has the right to withdraw from the contract within 14 days, without giving any reason.

Withdrawal notice is sent to [email protected].

The right of withdrawal also applies to a natural person running a sole proprietorship, if the contract is not of a professional character for them (art. 38a of the Polish Consumer Rights Act).

Other businesses (e.g., companies) have no right of withdrawal.

Use of the Platform during the trial period (14 days) does not affect the right of withdrawal.

The Provider takes all reasonable measures to keep the Platform operational (SLA 99.5% per month).

The Provider is not liable for outages caused by force majeure, third-party actions (e.g., ISP), or maintenance scheduled with 24-hour notice.

Towards non-consumer Clients, the Provider's liability is limited to the value of the last 3 subscription payments - except for damage caused intentionally. This limitation does not apply to consumers.

Liability exclusions do not apply where mandatory law does not allow such exclusion.

Matters not regulated by these Terms are governed by Polish law.

Disputes with non-consumer Clients are settled by the court competent for the Provider's seat. For disputes with consumers, court jurisdiction follows the general rules of the Polish Civil Procedure Code.

These Terms become effective on June 1, 2026.
