If the Customer provides NetSendo with any feedback, suggestions, ideas, improvements or recommendations regarding the Software (“Feedback”), the Customer hereby grants NetSendo a perpetual, irrevocable, worldwide, royalty-free and sublicensable licence to use, modify, incorporate and commercialize such Feedback for any purpose, without compensation or attribution.

The Customer warrants that providing such Feedback does not infringe any third-party rights.

Except for the limited licence expressly granted under this EULA, no other rights or licences are granted to the Customer, whether by implication, estoppel or otherwise.

Intellectual Property Rights in Open-Source Software components included in the Software remain governed by their respective open-source licences.

A non-exhaustive list of third-party and open-source dependencies may be made available through the Repository, Documentation or relevant configuration files.

Each Open-Source Software component included in or used by the Software is licensed under its respective open-source licence.

The Customer agrees to comply with all applicable open-source licence terms when using such components.

In the event of any conflict between the terms of this EULA and the terms of an applicable open-source licence, the open-source licence shall prevail, but only with respect to the specific Open-Source Software component to which such conflict relates.

Nothing in this Section shall be interpreted as granting the Customer any rights to proprietary components of the Software beyond those expressly granted under this EULA.

Open-source licences do not apply to proprietary features, extensions, branding, licence mechanisms or other non-open-source elements of the Software.

Open-Source Software components are provided “AS IS” and without warranties of any kind, to the maximum extent permitted by applicable law.

To the extent permitted by law, NetSendo disclaims all liability arising from the use, modification or distribution of Open-Source Software components.

The Customer is solely responsible for:

• a) reviewing and understanding the applicable open-source licences;

• a) degraded functionality;
• b) increased security risks;
• c) loss of access to certain features;
• d) exclusion of liability on the part of NetSendo for resulting issues.

NetSendo shall use commercially reasonable efforts to avoid material regressions, but does not warrant full backward compatibility with prior versions, configurations or third-party integrations.

The Customer is responsible for testing Updates and New Releases in non-production environments prior to deployment.

All Updates and New Releases are deemed part of the Software and are subject to this EULA, unless expressly stated otherwise by NetSendo in writing.

Updates or New Releases do not grant any additional rights beyond those granted under this EULA.

The Customer may modify Open-Source Software components in accordance with their respective licences.

The Customer shall not modify proprietary components of the Software except to the extent expressly permitted by applicable mandatory law.

Any modifications made by the Customer are undertaken at the Customer’s own risk.

NetSendo may designate certain features as experimental, beta or deprecated.

Such features may be changed, limited or removed at any time and are provided without warranties or guarantees of any kind.

Access to features available under the GOLD Licence is subject to payment of a recurring subscription fee (“Subscription Fee”) as published or otherwise communicated by NetSendo.

Subscription Fees are charged in advance for the applicable billing period.

The Customer acknowledges that:

• a) no fee is charged for the licence itself;
• b) Subscription Fees relate exclusively to access to additional or extended functionality enabled under the GOLD Licence;
• c) termination or expiration of a Subscription does not revoke the underlying licence to use the Software under the SILVER Licence.

Each billing period renews automatically unless cancelled prior to the end of the current billing period.

The Customer shall provide valid and up-to-date payment information and authorizes NetSendo or its payment processor to charge the applicable Subscription Fees.

NetSendo is not responsible for errors or interruptions caused by third-party payment providers.

All Subscription Fees are exclusive of any applicable taxes, duties or charges, including value added tax (VAT), sales tax or similar governmental charges, unless expressly stated otherwise.

The Customer is responsible for payment of all applicable taxes.

NetSendo reserves the right to change Subscription Fees at any time.

Any price changes shall apply only to subsequent billing periods and shall not affect the current active billing period.

Continued use of GOLD features after a price change constitutes acceptance of the updated pricing.

Except where required by mandatory applicable law, Subscription Fees are non-refundable, including in cases of:

• a) unused Subscription periods;
• b) partial use of GOLD features;
• c) suspension or termination due to breach of this EULA.

While NetSendo may implement reasonable security practices during development, NetSendo does not warrant that the Software is free from vulnerabilities, defects or security risks.

Some jurisdictions do not allow the exclusion of certain warranties.

In such cases, the exclusions and disclaimers in this Section shall apply to the maximum extent permitted by applicable law.

To the maximum extent permitted by applicable law, NetSendo shall not be liable for any indirect, incidental, special, consequential or punitive damages, including but not limited to:

• a) loss of profits, revenue or business opportunities;
• b) loss of data or data corruption;
• c) business interruption or downtime;
• d) loss of goodwill or reputation;
• e) costs of substitute software, services or infrastructure.

This exclusion applies regardless of the legal theory under which such damages are claimed.

To the maximum extent permitted by applicable law, NetSendo’s total aggregate liability arising out of or in connection with this EULA or the use of the Software shall not exceed:

• a) in the case of the SILVER Licence – EUR 0 (zero);
• b) in the case of the GOLD Licence – the total Subscription Fees actually paid by the Customer to NetSendo during the three (3) months preceding the event giving rise to the claim.

The Customer acknowledges that:

• a) the limitations of liability set out in this EULA reflect a reasonable allocation of risk;
• b) the Software is provided without a licence fee under the SILVER Licence;
• c) Subscription Fees under the GOLD Licence relate solely to feature availability and not to warranties, guarantees or liability assumptions.

The Customer agrees that NetSendo would not provide the Software without these limitations.

The limitations and exclusions in this Section apply even if NetSendo has been advised of the possibility of such damages or losses.

Nothing in this EULA shall exclude or limit liability to the extent that such exclusion or limitation is prohibited by mandatory applicable law.

In such cases, NetSendo’s liability shall be limited to the minimum extent permitted by law.

NetSendo shall not be liable for any claims, damages or losses arising from:

• a) the Customer’s use of third-party services or integrations;
• b) actions or omissions of the Customer or its users;
• c) violations of law by the Customer;
• d) misuse of the Software contrary to this EULA.

The Customer shall indemnify, defend and hold harmless NetSendo, its Affiliates, officers, directors, employees and contractors from and against any and all claims, demands, actions, proceedings, damages, losses, liabilities, costs and expenses (including reasonable legal fees) arising out of or related to:

• a) the Customer’s use of the Software;
• b) any Customer Data processed, stored or transmitted using the Software;
• c) any communications, messages or campaigns sent using the Software;
• d) the Customer’s breach of this EULA;
• e) the Customer’s violation of applicable laws or regulations.

The indemnification obligation includes, without limitation, claims arising from:

• a) violations of data protection or privacy laws;
• b) violations of electronic communications, marketing or anti-spam laws;
• c) consumer protection claims;
• d) intellectual property infringement resulting from Customer Data or content;
• e) misuse of third-party services or integrations.

The Customer shall:

• a) promptly notify NetSendo of any claim subject to indemnification;
• b) provide reasonable cooperation in the defense or settlement of such claim;
• c) not settle any claim in a manner that imposes liability or obligations on NetSendo without NetSendo’s prior written consent.

NetSendo reserves the right, at its option, to assume control of the defense and settlement of any claim subject to indemnification, without limiting the Customer’s indemnification obligations.

The indemnification obligations under this Section shall survive termination or expiration of this EULA.

This EULA enters into force upon the Customer’s first download, installation, access or use of the Software and remains in effect until terminated in accordance with this Section.

• a) Under the SILVER Licence, the licence is granted for an indefinite term, subject to termination in accordance with this EULA.
• b) Under the GOLD Licence, access to GOLD features is granted for the duration of an active Subscription, without affecting the underlying licence granted under the SILVER Licence.

The Customer may terminate this EULA at any time by:

• a) ceasing all use of the Software; and
• b) deleting all copies of proprietary components of the Software in the Customer’s possession or control.

Termination of a GOLD Subscription does not automatically terminate this EULA.

NetSendo may terminate this EULA, in whole or in part, with immediate effect upon written notice if the Customer:

• a) materially breaches this EULA;
• b) engages in any Prohibited Use under Section 7;
• c) attempts to circumvent licensing, technical or security measures;
• d) fails to pay applicable Subscription Fees after notice;
• e) uses the Software in violation of applicable law.

NetSendo may suspend access to the Software or to GOLD features, without terminating this EULA, where reasonably necessary to:

• a) prevent or investigate misuse;
• b) protect NetSendo’s rights or security;
• c) comply with legal obligations.

Upon termination of this EULA:

• a) all licences granted under this EULA shall immediately cease;
• b) the Customer shall cease all use of the Software;
• c) Sections intended by their nature to survive termination shall remain in effect.

Termination or expiration of a GOLD Subscription shall result solely in loss of access to GOLD features and shall not affect the Customer’s ability to use the Software under the SILVER Licence, unless this EULA is otherwise terminated.

To the maximum extent permitted by law, NetSendo shall not be liable for any damages, losses or costs arising from termination or suspension of this EULA or a GOLD Subscription in accordance with its terms.

The following Sections shall survive termination or expiration of this EULA: Sections 7, 8, 9, 13, 15, 16, 17, 18, and any other provisions which by their nature should survive.

The Customer shall use the Software strictly in accordance with this EULA and shall ensure ongoing compliance with all licence terms, restrictions and limitations.

To the extent reasonably necessary to verify compliance with this EULA, NetSendo may request information from the Customer regarding:

• a) the scope and manner of use of the Software;
• b) enabled features and licence tier usage;
• c) number and type of environments in which the Software is deployed.

Such verification shall be conducted in a manner that is reasonable, proportionate and does not require access to Customer Data or confidential business information beyond what is strictly necessary.

NetSendo shall not require direct access to the Customer’s infrastructure, systems or data for audit purposes, unless expressly agreed by the Customer or required by law. Any verification shall, where possible, be performed through self-certification, documentation or technical indicators.

If verification reveals that the Customer has used the Software in excess of or outside the scope permitted under this EULA, NetSendo may:

• a) require the Customer to immediately cease such unauthorized use;
• b) require payment of applicable Subscription Fees that would have been payable for such use;
• c) suspend or terminate the licence in accordance with this EULA.

Failure by NetSendo to enforce compliance at any time shall not constitute a waiver of its rights under this EULA.

The Customer shall maintain reasonable records sufficient to demonstrate compliance with this EULA, to the extent required by applicable law.

Neither party shall be liable for any failure or delay in the performance of its obligations under this EULA (other than payment obligations) if such failure or delay results from events beyond its reasonable control (“Force Majeure Event”).

Force Majeure Events include, without limitation:

• a) acts of God, natural disasters, floods, fires, earthquakes or epidemics;
• b) war, terrorism, civil unrest, riots or armed conflict;
• c) acts of government, changes in laws or regulations, court orders or sanctions;
• d) labor disputes, strikes or shortages of personnel;
• e) failures of utilities, telecommunications, internet service providers or cloud infrastructure;
• f) failures or actions of third-party service providers.

During the continuance of a Force Majeure Event:

• a) the affected party’s obligations shall be suspended to the extent impacted by the Force Majeure Event;
• b) the affected party shall use reasonable efforts to mitigate the effects of the Force Majeure Event.

A Force Majeure Event shall not give rise to any right to terminate this EULA, except where such right is required by mandatory applicable law.

The Customer shall not assign, transfer, sublicense, delegate or otherwise dispose of any rights or obligations under this EULA, whether by operation of law, merger, change of control or otherwise, without the prior written consent of NetSendo.

Any attempted assignment or transfer in violation of this Section shall be null and void.

NetSendo may assign or transfer this EULA, in whole or in part, without the Customer’s consent, including in connection with:

• a) a merger, acquisition or sale of assets;
• b) a corporate reorganization or restructuring;
• c) a change of control or ownership;
• d) assignment to an Affiliate.

Any permitted assignment or transfer shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns.

This EULA and any disputes, claims or obligations arising out of or in connection with it shall be governed by and construed in accordance with the laws of the Republic of Poland, without regard to its conflict of law principles.

Any disputes arising out of or in connection with this EULA shall be subject to the exclusive jurisdiction of the competent common courts of the Republic of Poland, with jurisdiction determined according to NetSendo’s registered seat, unless mandatory applicable law provides otherwise.

The United Nations Convention on Contracts for the International Sale of Goods (CISG) shall not apply to this EULA.

NetSendo reserves the right to amend, modify or update this EULA from time to time, including to reflect:

• a) changes in the Software or its functionality;
• b) legal, regulatory or compliance requirements;
• c) security, operational or business considerations.

NetSendo may notify the Customer of amendments to this EULA by:

• a) publishing the updated version on its website or in the Repository;
• b) including the updated EULA in the Software or Documentation;
• c) providing notice through release notes or other reasonable means.

Continued use of the Software after the effective date of an amended EULA constitutes the Customer’s acceptance of such amendments.

If the Customer does not agree to the amended EULA, the Customer must discontinue use of the Software.

Unless required by mandatory applicable law, amendments to this EULA shall apply prospectively and shall not retroactively affect rights or obligations accrued prior to the effective date of the amendment.

If any provision of this EULA is held to be invalid, illegal or unenforceable by a court of competent jurisdiction, such provision shall be:

• a) deemed modified to the minimum extent necessary to make it valid and enforceable; or
• b) if such modification is not possible, severed from this EULA.

The remaining provisions of this EULA shall remain in full force and effect.

The invalidity or unenforceability of any provision shall not affect the validity or enforceability of any other provision of this EULA.

This EULA constitutes the entire agreement between the Customer and NetSendo regarding the use of the Software and supersedes all prior or contemporaneous agreements, understandings or representations, whether written or oral, relating to the Software.

The Customer acknowledges that it has not relied on any statement, representation or warranty not expressly set out in this EULA.

In the event of any inconsistency between this EULA and any other document relating to the Software, this EULA shall prevail unless expressly stated otherwise in writing by NetSendo.
