Synikon provides residential building management software via the internet. The Service may include, among others, the following functions:

• recording building/unit details,

• managing allocation shares and expense categories,

• recording expenses and invoices,

• issuing common charge statements/notices,

• tracking payments and debts,

• collecting Common Charges for the account of the Beneficiary and remitting them to the Settlement Account, in accordance with the section "Collection of Common Charges on Behalf of the Beneficiary",

• sending notifications via email or other channels,

• storing and processing documents,

• automated data extraction from documents (AI).

The Service is provided "as is" and is continuously evolving. Synikon reserves the right to modify, add or remove features, subject to the "Changes to Terms" section.

The User must provide truthful, accurate and up-to-date information upon registration and keep it updated.

The User is solely responsible for:

• maintaining the confidentiality of access credentials (passwords, tokens, etc.),

• all activity performed through their Account,

• immediately notifying Synikon in the event of unauthorised access or a security breach.

Synikon may impose security restrictions (e.g. password policy, time limits, maximum login attempts) to protect the Service.

Available Subscriptions, charges, duration and features are presented on the Website and/or within the Service.

Subscription billing is carried out in accordance with the terms displayed at the time of package selection and payment completion.

The User acknowledges that:

• any applicable taxes or deductions apply in accordance with applicable law,

• Synikon may use third-party payment providers,

• Synikon does not store payment card details where processing is carried out by a third-party payment provider.

Access to the Service may be conditional on successful payment/billing where required.

Collection Mandate

The Customer, acting as manager or duly authorised representative of the Beneficiary, grants Synikon an express mandate and authorisation to collect Common Charges in the name and for the account of the Beneficiary, through the electronic payment methods made available by the Service.

The Customer represents and warrants that it holds such authorisation from the Beneficiary, pursuant to the building regulations and/or a resolution of the general assembly of co-owners.

Payment of Common Charges to Synikon under this mandate discharges the payer's debt towards the Beneficiary as at the time of payment.

Legal nature

Synikon acts solely as agent of the Beneficiary for the collection of Common Charges and does not provide payment services for its own account. Electronic payments are executed by a licensed Payment Provider.

Collected Common Charges belong to the Beneficiary and do not constitute revenue, an asset or capital of Synikon. Synikon does not hold funds and does not use such amounts for any purpose other than remitting them.

Remittance to the Beneficiary

Collected Common Charges are remitted to the Settlement Account declared by the Customer, after they have been cleared by the Payment Provider and without undue delay.

Remittance is carried out automatically, on a daily basis, provided the amount due for remittance exceeds the minimum threshold announced within the Service, or in any event within the number of days specified therein from collection.

The Customer may at any time review, within the Service, amounts collected, amounts pending remittance, and the remittance history.

Settlement Account – declaration of ownership

The Customer declares the Settlement Account and confirms to whom it belongs: to the Beneficiary (an account in the name of the building) or personally to the manager.

The Customer acknowledges that, where a personal account is declared, the Customer bears sole responsibility for the onward disposal of the amounts to the Beneficiary, as well as for any tax and accounting consequences. Synikon discharges its obligations by remitting to the declared account.

Upon a change in the person of the manager, Settlement Account details that do not belong to the Beneficiary cease to apply and a new declaration is required.

Liability for non-payment

Synikon does not guarantee payment of Common Charges by those liable and assumes no obligation to advance, extend credit for, or cover uncollected amounts. Collection is limited to amounts actually paid.

In the event of a chargeback, cancellation or refund of a payment after it has been remitted, the Customer shall return the corresponding amount, or it shall be set off against subsequent remittances.

Electronic collections are subject to an acceptance cost charged by the Payment Provider, which varies by payment method, as well as an outgoing bank transfer cost upon remittance.

These costs are passed on to the Beneficiary at cost, without any mark-up or profit margin for Synikon, and are recorded as a common expense with a distinct description, so as to be visible to the Beneficiary.

The pass-through does not constitute a surcharge per payment instrument on the payer: the expense is allocated among those liable in accordance with the applicable allocation method, irrespective of the instrument each of them used to pay.

The applicable rates and amounts are announced within the Service and may change if the Payment Provider's price list changes.

The Customer may cancel their Subscription at any time with no cancellation fee, by contacting support@synikon.gr or through available functions within the Service, where provided.

• Cancellation within the seven (7) day trial period: no charge. The Account and/or paid access is deactivated immediately or as described within the Service.

• Cancellation of an active paid Subscription: the Service remains active until the end of the already-paid period. No refunds are issued for periods already charged/paid, unless otherwise required by mandatory legal provisions.

• Data retention and deletion: after cancellation or termination of the Account, Customer Data is retained for thirty (30) days solely for the purpose of recovery or export by the User, and is then deleted or anonymised, unless retention is required for compliance with legal obligations.

• Reactivation: the Customer may reactivate their Subscription within thirty (30) days of cancellation without data loss, provided the data has not been deleted.

The User must export any data they wish to retain before cancellation/deletion, using the available tools within the Service.

Where the Customer is a consumer, they may have a right of withdrawal within fourteen (14) calendar days of conclusion of the contract, in accordance with applicable law.

Where, upon registration or activation of the Service, the User expressly requests immediate commencement of the Service before the withdrawal period has expired, the User acknowledges that they have been informed of the consequences provided by applicable law regarding the exercise of the right of withdrawal after performance of the contract has begun.

During any free trial period, the User may discontinue use at any time without charge, in accordance with the terms of the relevant trial programme as displayed on the Website and/or within the Service.

The User agrees to use the Service exclusively for lawful purposes and in accordance with these Terms, good faith and fair dealing.

In particular, the following are prohibited:

• using the Service for illegal activities or infringement of third-party rights,

• uploading or distributing malware, harmful content or content that may affect the operation of the Service,

• attempting unauthorised access to systems, accounts or other users' data,

• interfering with, overloading or undermining the security or availability of the Service,

• reselling, transferring, sublicensing, assigning or commercially exploiting the Service without prior written consent from Synikon,

• using the Service in a manner that violates any technical restrictions or intellectual property rights.

Synikon may suspend or terminate access in the event of a breach of this section, in accordance with the "Suspension – Termination" section.

Customer Data remains under the ownership or control of the Customer/User, depending on its nature and the rights held by the User over it.

The User grants Synikon a non-exclusive, limited, revocable licence to use, host, store, reproduce and process Customer Data solely for the purpose of providing, supporting, maintaining and improving the Service, as well as for security, fraud prevention and technical troubleshooting purposes.

The User represents and warrants that:

• they hold the necessary rights and/or authorisations to input and process Customer Data,

• they do not input content that infringes third-party rights,

• the data they enter is accurate to the extent they know or ought to know.

Synikon does not acquire ownership rights over Customer Data.

Synikon processes personal data in accordance with its Privacy Policy and applicable law.

In the context of using the Service for building management, the Customer may input data of third parties (e.g. owners, tenants, co-owners, contact details, financial statements/debts). The User acknowledges that they must have a lawful basis for the processing and entry of such data.

To the extent that the Customer determines the purposes and means of processing the data they enter into the Service, the Customer acts as Data Controller and Synikon acts as Data Processor, processing the data solely for the purpose of providing the Service and in accordance with the Customer's instructions.

The Service may provide automated document processing features, such as extracting fields from invoices/documents, to facilitate data entry and management.

The User acknowledges that:

• the accuracy of data extraction may be affected by document quality and other technical factors,

• they must check and verify the accuracy of the data before using it as the basis for financial or other decisions,

• the use of AI features does not replace accounting, legal or technical review where required.

The Service, including its software, code, design, databases, content, graphics, logo, trademarks and all related material, is the intellectual property of Synikon or its licensors and is protected by applicable law.

The User is granted a limited, non-exclusive, non-transferable licence to access and use the Service solely for the purposes for which it is provided and in accordance with these Terms.

Without prior written consent from Synikon, the following are prohibited:

• copying, reproducing, modifying, distributing or publicly displaying any part or all of the Service,

• decompiling, disassembling or reverse engineering the Service,

• removing copyright notices or trademarks.

Synikon makes reasonable efforts to ensure smooth operation and availability of the Service, but does not guarantee that the Service will be uninterrupted, error-free or completely secure against all possible threats.

Synikon may carry out maintenance, updates or upgrades that may temporarily affect availability.

Technical support is provided through the communication channels listed in the "Contact" section, subject to the announced support hours and conditions.

To the maximum extent permitted by applicable law, Synikon is not liable for:

• indirect or consequential damages,

• loss of profits,

• lost revenue,

• data loss caused by actions or omissions of the User, third parties or events beyond Synikon's reasonable control,

• temporary or permanent inability to access the Service due to maintenance, upgrades or technical failures.

Synikon does not provide accounting, tax or legal advice. The Service is a management tool and the User remains solely responsible for the legality, accuracy and use of their entries and the results generated.

Synikon does not act as a payment institution, electronic money institution or custodian. Payments are executed by a licensed Payment Provider and Synikon is not liable for that provider's acts, omissions, interruptions or failures, save where Synikon is at fault in performing the Collection Mandate.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, in particular in cases of fraud or where mandatory legal provisions apply, including consumer rights.

The User may terminate their Account at any time, in accordance with the "Cancellation Policy" section and/or by contacting Synikon.

Synikon may suspend or terminate access to the Service, with or without notice, where:

• the User breaches material terms of these Terms,

• there is reasonable suspicion of abuse, fraud or unauthorised access,

• required for security, compliance or protection of Synikon's or third parties' rights,

• the User delays or fails to fulfil payment obligations (for paid Subscriptions).

Upon termination, the data retention/deletion policy described in the "Cancellation Policy" section applies, subject to legal retention obligations.

The parties must keep confidential any information received in the context of their relationship that is not public or widely known, unless disclosure is required by law or a competent authority.

This section does not limit the User's rights as a data subject or Synikon's obligations under the Privacy Policy.

Synikon reserves the right to modify these Terms of Service.

Non-material changes — such as clarifications, corrections, rewording, renumbering of sections, adjustments to legal or regulatory requirements, as well as additions relating to new or optional features which the User is free to choose whether to use — take effect immediately upon publication on synikon.gr, where the date of last update is displayed.

In the event of material changes that adversely affect the User's rights or obligations, Synikon will notify the User via email and/or within the Service within a reasonable time before they take effect. In such cases, the User is entitled to discontinue use of the Service or cancel their subscription before the changes take effect, at no additional charge.

Continued use of the Service after the changes take effect constitutes acceptance of the updated Terms.

These Terms are governed by Greek law.

Any dispute arising from these Terms or the use of the Service shall be subject to the courts determined by applicable law.

Where the User is a consumer, the judicial protection rights granted to them by mandatory legal provisions are not affected.
