Email: [email protected] · Certified email (PEC): [email protected]

In these Terms «CKM», «we» and «us» mean CKM SOFTWARE S.R.L.; «you» and «User» mean whoever uses RENTAX.

2. What these Terms are

2.1 These Terms are the contract between you and CKM for the use of RENTAX: the iOS and Android app, the web version and the related services (the «Service»). You accept them by ticking the dedicated box when you create your account or when you buy a subscription. You can read, download and print them at any time at the address above.

2.2 The contract also includes:

(a) the Privacy Notice (https://rentaxapp.com/app/privacy/), which explains how we process your personal data. The Privacy Notice is not a consent: where consent is needed, it is asked for separately;

(b) Annex A, «Agreement on the processing of data on behalf of the User», which applies when you enter into RENTAX data of guests, tenants, staff or other people.

2.3 If you download the app from the App Store, Apple's standard Licensed Application End User License Agreement also applies. If you download it from Google Play, the Google Play Terms of Service also apply. These Terms govern the Service. Apple and Google are not parties to the contract between you and CKM and are not responsible for the Service.

2.4 RENTAX is for adults only. By creating an account you declare that you are at least 18 years old.

3. Consumers and business customers

3.1 You are a «Consumer» if you use RENTAX for purposes outside your trade, business, craft or profession. This is the case, for example, of a private individual who lets their own home for short stays without a VAT number, or of an owner managing their own properties.

3.2 You are a «Business Customer» if you use RENTAX for your business: a company, sole trader, partnership, accommodation business, property manager, or professional with a VAT number.

3.3 When you create your account we ask whether you use RENTAX for your business. Your answer, recorded with the date and the version of the Terms, determines which rules apply. If your situation changes, update it in Settings.

3.4 Consumers always keep the rights that the law grants them and that no contract can remove, including, for those resident outside Italy, the mandatory rights of the law of their country of residence. Clauses stated to apply only to Business Customers do not apply to Consumers.

3.5 Anyone accepting on behalf of a company or organisation declares that they have the power to bind it. In that case the Customer is the company or organisation.

4. The Service

4.1 RENTAX brings together three management tools in a single app:

(a) Host, for holiday homes, short lets and B&Bs;

(b) Hotel, for hotels, residences and multi-unit properties;

(c) Invest, for owners and investors in let properties.

4.2 Depending on the plan chosen, the Service includes:

(a) connection to booking portals (channel manager): synchronisation of availability, rates and bookings with Booking.com, Airbnb and other portals, and guest messaging, through the technical partner Channex.io Ltd;

(b) online guest check-in, including collection of identity documents;

(c) preparation and sending, on your instructions, of guest registrations to the Italian State Police (Alloggiati Web), of ISTAT and regional statistical data and of tourist tax calculations, and management of the national identification code (CIN);

(d) cleaning and staff, with roles and permissions;

(e) tenants, lease agreements, deadlines, collections and arrears;

(f) tax calculations for Italy: IRPEF, flat-rate rental tax (cedolare secca), IMU, F24 payment forms and draft data for the income tax return;

(g) connection to bank accounts (Open Banking) through finAPI GmbH;

(h) AI document reading and an AI assistant;

(i) sharing the same properties with family members and other invited users;

(j) data export for your accountant.

4.3 The features included in each plan, the limits (number of properties, units, users, AI messages) and the prices are shown on the purchase screen of the app, in the store and on the website, before you pay.

4.4 Third-party services. Some features depend on third-party services (portals, Alloggiati Web, regional and municipal portals, banks, stores). Your relationship with each portal, bank or authority is between you and them only. CKM is responsible for its own Service and its own technical suppliers, not for what an independent third party does or stops doing.

5. Tax calculations, compliance and artificial intelligence

5.1 Tax calculations are estimates based on the data you enter or import. They follow the Italian tax rules in force at the time of the calculation. They are not tax, legal or financial advice and do not replace an accountant or another qualified professional. RENTAX does not file tax returns or pay taxes on your behalf.

5.2 If you also have income or property abroad, RENTAX calculates only the Italian part. Taxes due in the foreign country and the effects of double taxation treaties are not calculated, and the app says so.

5.3 Obligations towards authorities (guest registrations, ISTAT, tourist tax, CIN, registration of leases, payments) remain your obligations. RENTAX prepares them and, if you so choose, sends them with your credentials and on your instructions. Before sending we show you a summary. After sending, check the outcome shown in the app. If a submission fails, the app tells you.

5.4 The assistant and document reading use artificial intelligence systems. When you interact with the assistant you are talking to an AI, not a person, and AI-generated content is labelled as such. Answers and extracted data may contain errors: check them before using them. The decision always remains yours.

5.5 Nothing in this clause limits CKM's liability as set out in clause 13.

6. Account, invited users and security

6.1 To use the Service you create an account with true and up-to-date data. Keep your credentials safe, do not share them, and tell us immediately at [email protected] if you suspect unauthorised access.

6.2 The account holder may invite family members, collaborators and staff (cleaning, reception, managers) and give each one a role with limited permissions. The account holder chooses whom to invite and which data to share, and may revoke access at any time. Each invited user accepts these Terms for their own use.

6.3 Bank connection. Connecting bank accounts is optional. You activate it by giving your consent directly to finAPI GmbH, on its terms, and you can revoke it at any time. RENTAX reads transactions on a read-only basis and does not initiate payments.

7. Proper use and connection to portals

7.1 You may not use RENTAX for unlawful purposes, enter false data, access other users' data, circumvent security measures, decompile the app except as permitted by law, use automated systems to extract data, or resell or make the Service available to third parties.

7.2 Connection to portals. The connection to Booking.com, Airbnb and other portals works through Channex.io Ltd, RENTAX's technical partner. By connecting a property you represent and warrant that:

(a) the property is yours, or you have the power to manage it;

(b) property type, number of units, location, amenities, codes and licences (CIN and regional permits) entered in RENTAX are true, and you update them as soon as they change;

(c) you publish only the availability you actually have and rates you intend to honour, and you do not accept bookings you know you cannot honour;

(d) you comply with each portal's contract and rules on rates, parity, cancellations and content;

(e) you do not enter false or altered booking data;

(f) you write to guests only to manage their booking, unless they consent or there is another legal basis;

(g) you do not share your credentials and do not use the service unlawfully.

Your relationship with each portal (terms, commissions, content rules, use of data) is between you and the portal only.

7.3 If you breach this clause we notify you and give you a reasonable time to remedy it. Only where the breach puts guests, data security or other users' connections at risk may we immediately suspend the feature concerned (for example the portal connection of one property), informing you immediately afterwards of the reason. The rest of the subscription remains active.

8. Data you enter and third-party data

8.1 The data you enter remain yours. You grant us only the right to use them to provide the Service. You can export them at any time using the export features.

8.2 For the personal data of guests, tenants, staff and other people that you enter, you are the controller and CKM processes those data on your behalf as processor, under Annex A. You undertake to have a legal basis for processing them and to give those people the information due.

8.3 For your own data as a User, CKM is the controller, as described in the Privacy Notice.

9. Subscriptions, AI credits and payments

9.1 Some features require a paid subscription. Plan, content, total price including VAT, length of the period and renewal terms are shown on the purchase screen before payment. The payment button states that the order involves an obligation to pay.

9.2 You can pay:

(a) through Apple or Google in-app purchase: in this case payment, the store's invoicing, management and cancellation of the subscription follow the store's rules;

(b) on the website, using the payment methods shown at checkout: in this case we email you a confirmation with a summary of the contract.

9.3 Monthly subscription. It is for an indefinite term, with no minimum period, paid in advance month by month. You can cancel it at any time: cancellation takes effect at the end of the month already paid.

9.4 Annual subscription, where offered. It lasts twelve months and renews automatically for a further twelve unless cancelled before expiry. At least 30 days before each renewal we send you a notice with the renewal date, the price and how to cancel.

9.5 How to cancel: in the App Store subscription settings (Apple account, Subscriptions) or in Google Play (Payments & subscriptions, Subscriptions) for in-app purchases; in the Subscription section of the app or website for web purchases. A store may require cancellation a certain time before renewal: the Subscription screen of the app shows the date by which to cancel.

9.6 Change of plan. If you upgrade, the change applies immediately and you pay the difference under the rules of the store or checkout. If you downgrade, the change applies from the next renewal.

9.7 AI credits. You may separately buy packs of credits for AI messages and document reading. Credits remain valid while your account is active, cannot be exchanged for money and cannot be transferred to other accounts. If we discontinue the Service by our own decision, we refund unused credits.

9.8 There is no free trial, except offers presented from time to time on the purchase screen with all their conditions.

9.9 If a payment fails, the store or we will notify you. Until payment is regularised, paid features may be suspended. Your data remain stored and downloadable.

10. Consumer right of withdrawal

10.1 If you are a Consumer you may withdraw from the subscription contract within 14 days of its conclusion, without giving any reason and at no cost. The same applies to an upgrade, limited to the change of plan.

10.2 How to withdraw: using the «Withdraw from contract here» function in the Subscription section of the app and website; or by an explicit statement sent to [email protected] or to the PEC [email protected], which may use the model form at the end of this clause. It is enough to send it within the 14 days.

10.3 If you asked for the Service to start immediately, which happens when you activate the subscription, on withdrawal you pay only for the part of the Service used up to the notice of withdrawal, in proportion to the price of the period. We refund the rest within 14 days of receiving your withdrawal.

10.4 Refunds for in-app purchases. You may also ask Apple or Google directly for a refund, under their procedures. If the store does not refund, we refund you, with your express consent to a different means (for example bank transfer) and at no cost to you. We do not refund the same amount twice.

10.5 AI credits. Withdrawal from AI credits is excluded only for a fully used pack, and only if before buying you gave your express consent to start immediately and acknowledged that, once the pack is fully used, you lose the right of withdrawal. For unused credits the right of withdrawal remains.

10.6 Deleting your account is not a withdrawal and does not by itself give rise to a refund. To withdraw, use the function in clause 10.2. To avoid paying for a renewal, cancel the subscription as in clause 9.5. Uninstalling the app does not cancel the subscription.

10.7 Model withdrawal form (complete and return it only if you wish to withdraw):

«To: CKM SOFTWARE S.R.L., Via Postumia 9, 76125 Trani (BT), Italy, [email protected], [email protected]. I hereby give notice that I withdraw from my contract for the provision of the following service: RENTAX subscription [plan]. Concluded on [date]. Name of consumer. Account email address. Date.»

11. Conformity of the Service

11.1 If you are a Consumer, CKM is liable for any lack of conformity of the Service under the legal guarantee for digital content and digital services provided by consumer law. Report the defect to [email protected]: we fix it free of charge; if that is not possible, you are entitled to a price reduction or to terminate the contract, in the cases provided by law.

11.2 We provide the updates, including security updates, needed to keep the Service in conformity. Please install them.

11.3 We may temporarily interrupt the Service for maintenance or security. Scheduled maintenance is carried out, as far as possible, at times of low use and announced in the app.

12. Changes to the Service, prices and Terms

12.1 We may change the Service, prices or these Terms only for one of these reasons: (a) changes in the law, in decisions of authorities or in store rules; (b) changes in the services of suppliers and technical partners beyond our control; (c) security needs; (d) adding or improving features; (e) a documented increase in the cost of providing the Service, for prices only.

12.2 We notify you by email and in the app at least 30 days in advance, with the reason and a description of the change. A price increase applies from the first renewal after the notice period ends. For in-app purchases, the store may ask you to confirm the new price.

12.3 If the change is unfavourable to you, you may withdraw at no cost before it takes effect, and we refund the part already paid and not used. A change to your detriment does not take effect through silence: if you do not accept it, the contract continues on the previous terms until the end of the paid period.

12.4 Changes required solely by law or security may apply immediately, with immediate notice and the same right of withdrawal.

13. Liability

13.1 CKM is liable to all Users for wilful misconduct and gross negligence and for personal injury, and is liable for its technical suppliers as for itself.

13.2 Towards Consumers, CKM is liable for damage caused by non-performance in accordance with the law, without contractual limits. The statutory limits remain: recoverable damage is that foreseeable when the contract was made, except in case of wilful misconduct, and no compensation is due for damage the User could have avoided with ordinary diligence (for example by checking the outcome of a submission that the app reported as failed).

13.3 For Business Customers only: except in case of wilful misconduct or gross negligence and without prejudice to obligations that the law does not allow to be limited, CKM's aggregate liability for all claims arising from the contract, including Annex A and the acts of technical suppliers, shall not exceed the fees paid by the Customer in the twelve months preceding the event that caused the damage. The rights of data subjects under Article 82 of Regulation (EU) 2016/679 remain unaffected.

13.4 For Business Customers only: the Customer shall indemnify CKM against third-party claims (portals, guests, authorities) caused by a culpable breach of clause 7 or of Annex A by the Customer or its invited users.

14. Suspension, termination and deletion

14.1 We may suspend or close an account only for serious breach of these Terms, fraud, unlawful use or non-payment, after notifying you and giving you a reasonable time to remedy it, except for the urgent cases in clause 7.3.

14.2 If we decide to discontinue the Service, we will notify you at least 60 days in advance, refund the part paid and not used and any unused AI credits, and let you export your data until discontinuation.

14.3 You can delete your account at any time in the app (Settings, Account, Delete account) or at https://rentaxapp.com/delete-account/. Before deletion you can export your data. After deletion, data are erased as described in the Privacy Notice, except those we are legally required to keep. Remember clause 10.6: deleting your account does not cancel a subscription bought from a store.

15. Intellectual property

RENTAX, the software, graphics, texts and distinctive signs belong to CKM or its licensors. We grant you a personal, non-exclusive and non-transferable licence to use the Service under these Terms for the duration of the contract. «RENTAX» is a sign of CKM SOFTWARE S.R.L., subject of European Union trade mark application No. 019421517.

16. Notices, complaints and disputes

16.1 We write to you at your account email and in the app. You can write to us at [email protected] or to the PEC [email protected].

16.2 For any complaint write to [email protected]: we reply within 30 days.

16.3 These Terms are governed by Italian law. Consumers keep the more favourable mandatory rules of the country of their habitual residence.

16.4 For disputes with a Consumer, the court of the Consumer's place of residence or domicile has mandatory jurisdiction, if located in Italy. Consumers may also use the alternative dispute resolution bodies provided for by law.

16.5 For Business Customers only: the Court of Trani (Italy) has exclusive jurisdiction over any dispute.

17. Final provisions

17.1 If a clause is void or ineffective, the others remain valid.

17.2 Failure to exercise a right is not a waiver of it.

17.3 You may not assign the contract without our consent. We may assign it to a company of our group or to whoever acquires the Service, after notifying you, without reducing your rights. If you are a Consumer, in that case you may withdraw at no cost.

17.4 These Terms are available in Italian and English. For Business Customers the Italian text prevails. For Consumers, in case of discrepancy between versions, the meaning most favourable to the Consumer prevails.

18. Specific approval (Business Customers only)

Pursuant to Articles 1341 and 1342 of the Italian Civil Code, the Business Customer specifically approves, by a box separate from the one accepting the Terms, the following clauses: 7.3 (suspension of portal connection); 9.4 (automatic renewal of the annual subscription); 9.9 (suspension for non-payment); 12 (changes to the Service, prices and Terms); 13.3 (limitation of liability); 13.4 (indemnity); 14.1 (suspension and closure of the account); 16.5 (exclusive jurisdiction of the Court of Trani); 17.3 (assignment of the contract by CKM).
