2. Service description

2.1. The Service lets a class treasurer keep records of payments, expenses, and settlements within a class, and share reports with parents and the class council via public links.

2.2. The Service does not intermediate the class's money flows — all actual parent payments, expenses, and reimbursements take place outside the Service, which is used solely to record them. This does not apply to the Fees for using the Service itself (§ 4), which the User pays to the Operator via the external payment provider Stripe.

3. Account and User obligations

3.1. Creating an Account requires an email address and acceptance of these Terms and the Privacy Policy.

3.2. The User is responsible for keeping access to the email inbox linked to the Account confidential.

3.3. The User enters students' and guardians' data into the Service only to the extent necessary for class settlements. The User obtains authorization to process this data from the students' guardians on their own.

3.4. The User may not use the Service for unlawful activities, including collecting data beyond what is necessary for class settlements.

4. Fees and trial period

4.1. Use of the Service is paid on a per-Class basis. The Fee is 100 PLN gross (81.30 PLN net + 23% VAT) per Class per school year. The current Fee is published in the Price List.

4.2. A new Account receives a 60-day free trial period counted from the day the Account is created, covering the full functionality of all Classes, with no payment details required. Collections with fewer than 10 participants can be closed without limit during the trial and do not use it up. Closing the first collection with 10 or more participants in a given Class ends free use for that Class, even before the 60 days elapse.

4.3. In every Class created after the trial period ends, the User may run and close the first collection free of charge. Further use of that Class's full functionality requires paying the Fee.

4.4. The Fee provides the Class's full functionality until the nearest 30 September (end of the school year), but always for at least 6 months — if fewer than 6 months remain from the payment date to the nearest 30 September (payment on or after 1 April), the Fee also covers the entire next school year.

4.5. The Fee is paid one time via the payment provider Stripe (BLIK, payment card, Apple Pay, Google Pay). The Fee is not a subscription and does not renew automatically; extending access for another period requires paying the Fee again. The Fee applies to the single Class indicated at payment.

4.6. In an unpaid Class (after the free use described in § 4.2–4.3 ends, or after the paid period expires), only creating new collections is blocked — existing collections, payments, and expenses keep working unchanged. After the paid period expires, the User additionally has a 30-day grace period to renew with full functionality retained to that extent.

4.7. After the grace period, the Class enters read-only mode: making any changes is blocked, while access to all stored data and its export (PDF, CSV) remain available indefinitely and free of charge. The Class's data is not deleted due to non-payment. Paying the Fee at any time restores the Class's full functionality.

4.8. The Operator may limit the number of simultaneously unpaid Classes per Account (currently: two). Once the limit is reached, creating another Class requires paying for one of the existing unpaid Classes or creating the new Class without the free first collection described in § 4.3.

5. Invoices

5.1. Every Fee is documented with a VAT invoice issued in the Polish National e-Invoicing System (KSeF).

5.2. The invoice is issued to the details indicated by the User in the buyer profile: to a natural person or — once a NIP (tax ID) is provided — to a business. The User is responsible for the accuracy of the buyer details.

5.3. By accepting these Terms, the User consents to invoices being issued and delivered electronically. The invoice PDF is sent to the email address linked to the Account and is available for download in the Service.

5.4. If the Fee is refunded (in whole or in part), the Operator issues a correction invoice in KSeF and sends its PDF to the email address linked to the Account.

5.5. Invoices, as accounting documents, are retained for the period required by tax law — including after the Account is deleted (details in the Privacy Policy).

6. Complaints

6.1. Complaints about the Service may be submitted to the email address contact@nod.consulting.

6.2. A complaint should include: the email address linked to the Account, a description of the problem, and the expected resolution.

6.3. The Operator responds to a complaint within 14 days of receiving it, replying to the email address from which it was submitted. No response within this period to a complaint submitted by a consumer means the complaint is accepted.

7. Withdrawal from the contract

7.1. A User who is a consumer, or a natural person entering into a contract directly related to their business activity where the contract is not of a professional nature for them, may withdraw from the contract for paid access to a Class within 14 days of paying the Fee, without giving a reason. It is sufficient to send the withdrawal statement before the deadline to the email address contact@nod.consulting.

7.2. By paying the Fee, the User requests that the service begin before the withdrawal period expires. The User nevertheless retains the right of withdrawal described in § 7.1.

7.3. In the event of withdrawal, the Operator refunds the Fee in full, no later than within 14 days of receiving the statement, using the same payment method. The Class then returns to the unpaid state (§ 4.6).

8. Liability

8.1. The Operator strives to keep the Service available and working correctly but does not guarantee uninterrupted availability.

8.2. The Operator is not liable for damage resulting from errors the User introduces into the data in the Service, nor for the use of that data by persons to whom the User has shared public links.

8.3. The Operator's maximum liability towards the User in connection with use of the Service does not exceed the Fees paid by the User in the 12 months preceding the event. This limitation does not apply to consumers to the extent its application would be impermissible under applicable law.

9. Termination

9.1. The User may delete the Account at any time from the Account settings. Deletion irreversibly removes all classes and their data in accordance with the Privacy Policy. Issued invoices, as accounting documents, are retained after Account deletion for the period required by tax law (details in the Privacy Policy).

9.2. The Operator may terminate the agreement with 30 days' notice in the event of a breach of these Terms or discontinuation of the Service. In every case, the User retains the ability to export their data before the Account is deleted.

10. Changes to the Terms

10.1. The Operator may change these Terms with prior notice to Users sent to the email address linked to the Account and via an in-app announcement.

10.2. Changes take effect no earlier than 14 days after notification. Continued use of the Service after that date constitutes acceptance of the changes. For material changes, the Operator may make continued use of the Service conditional on re-accepting the Terms in the application.

10.3. A change in the Fee does not affect periods already paid for.

11. Governing law and jurisdiction

11.1. These Terms are governed by Polish law.

11.2. Disputes arising from these Terms are resolved by the court having jurisdiction over the Operator's seat, subject to consumer-protection provisions, under which the competent court for consumers is the court of their place of residence.

11.3. A consumer may use out-of-court complaint and redress procedures, including the assistance of municipal or district consumer ombudsmen and the provincial inspectorates of the Trade Inspection (Inspekcja Handlowa).
