Upon Your payment of a subscription fee to Us or when using a free version of Memsource, We grant You personal, non-exclusive, time-limited, non-transferable and revocable license to use Memsource, for as long as You comply with these Terms of Service. All rights not expressly granted in these Terms of Service are reserved.

If You fail to pay any subscription fee or any other amount payable to Us on its due date, We have the right to terminate Your account and the Agreement with immediate effect.

It is Your responsibility to comply with any obligation to pay any taxes and charges, arising from Your subscription to Memsource, in addition to the subscription fee, should You become subject to such obligations in Your home country.

If You are a natural person residing in the Russian Federation or Japan (and You are not a legal entity or a natural person—entrepreneur), You are not allowed to purchase any of Our paid subscription plans.


Your Responsibilities

You acknowledge that You are fully responsible for Your use of Memsource, including responsibility for compliance with all laws and regulations that are applicable to You or the content You use in connection with Memsource. You may not use Memsource in any unlawful manner or in any other manner that could damage, disable, or interfere with or reverse engineer Memsource. We may, at Our sole discretion, adopt rules for permitted and appropriate use of Memsource and may update them from time to time. These rules shall form an inseparable part of these Terms of Service and shall be available on Our website. We reserve the right to suspend or terminate provision of Our services immediately to any User whose activity disrupts or causes harm to Memsource infrastructure, or violates these Terms of Service, including the obligation to pay a subscription fee in line with the User’s subscription plan. We also reserve the right to suspend or terminate provision of Our services immediately to any User who is not Your employee or Your contractor.


Fair Use Policy

This Fair Use Policy applies to You only if Your subscription is based on a per-User pricing, such as the Team Start, Team, and Ultimate subscription plans. We typically do not limit the number of words that You upload to Memsource in these subscription plans and expect that Your use will be fair. For the purpose of these Terms of Service, Your use of Memsource is fair if it does not exceed the fair use allowance.

The fair use allowance is a word volume calculated in the following way: 100 words for each EUR (one euro) of Your subscription fee. Words are counted as source words in newly created jobs times the number of target languages. Words are counted towards the “word volume” only once—when a job is created. The job can then be analyzed, translated, and otherwise processed any number of times by any number of users without any impact on the word volume.

Should Your word volume exceed the volume defined as fair use in any three-month period by more than 20%, We have the right to initiate a re-negotiation of the subscription terms with You. If no agreement is reached between You and Us within 30 days, We may terminate Your account and the Agreement with a 30-day notice period during which You may use Your account in line with these Terms of Service and respecting the fair use policy.

Example: If Your monthly subscription fee is EUR 500, then Your monthly fair use allowance is 50,000 words monthly. If You exceed such volume in any given 3-month period by 20%, i.e. would reach 180,000 source words or more in newly created jobs, then We may notify You and initiate re-negotiation of Your subscription terms.


API Access

Access to Memsource services via the API is subject to usage limits. The number of permitted calls per logged in user is 6,000 per minute and 2,000 per minute for the users who are not logged in. Should Your number of calls exceed these usage limits more than once in any given day, We have the right to interrupt Your access to Memsource and initiate re-negotiation of Your subscription terms. If no agreement is reached between You and Us within 30 days, We may terminate Your account and the Agreement with a 30-day notice period during which You may use Your account in line with these Terms of Service and usage limits contained herein.


User Access

Unless otherwise specified, Memsource may not be accessed by more than the number of purchased Users; a User’s password may not be shared with any other individual; and User identification may be reassigned to a new individual only if it replaces another User who no longer requires ongoing use of the Memsource service.

You shall not sublicense or allow third parties individual user access to Memsource service, with the exception of Your employees and contractors who are using Memsource on Your behalf.



Memsource and the related documentation are provided by Us “as is” on a commercially reasonable basis and without warranties of any kind either expressed or implied.

We do not provide any warranty that Memsource Output (incl. translation memory, pre-translated, machine translated or otherwise translated documents) will be error-free and correct. You are solely responsible for the final correction of Memsource Output and its use. We are not liable for any damage, whether direct, indirect, incidental, special or consequential, including but not limited to, damage consisting in loss of profits, goodwill, use, data or other intangible losses (even if We have been advised of the possibility of such damages) arising out of or in connection with Your use of Memsource, which has not been caused willfully or by gross negligence.

You acknowledge that We do not warrant that the use of Memsource will be error-free and uninterrupted. We therefore assume no liability for temporary non-operability or impaired accessibility of Memsource due to, but without limitation to, technical difficulties, dependence on the services of third parties and other reasons out of the scope of Our control.

Although We periodically back up data in Memsource, You are solely responsible for creating backup copies of any of Your Content that You submit to Memsource.


Your Content and Data Processing

We will not use Your Content for any purpose other than to inform You of and provide You with Memsource services and to enhance Our services and product offerings.


General Terms Concerning Processing of Personal Data in Your Content

Based on the fact that We process Personal Data in the course of providing Memsource, for the purpose of Data Protection Laws, You are the controller of the Personal Data and We are the processor.

Personal Data processing by Us shall be governed by this Agreement and by any law of the European Union or any member state of the European Union, which is binding on Us with regard to You.

We shall:

  • only process Personal Data in accordance with Your documented instructions (including to the extent necessary to provide Memsource and to comply with Our obligations under this Agreement);

  • ensure that any natural person acting under Our authority who has access to Personal Data must only process them in accordance with Your instructions, unless required to do so by applicable law;

  • inform You if it is required by applicable law to process Personal Data other than in accordance with Your instructions, unless prohibited by law on important grounds of public interest;

  • inform You if, in Our opinion, any of Your instructions would breach Data Protection Laws; and

  • assist You with undertaking an assessment of the impact of processing Personal Data in Memsource, and with any consultations with a supervisory authority, if and to the extent an assessment or consultation is required to be carried out under Data Protection Laws.


Details of Processing Activities

Personal Data will be processed only for the purpose of providing Memsource to you and for the purpose of enhancing Our services and product offerings.

We will:

  • store and backup Your data;

  • temporarily use Your data to train machine learning models as described below;

  • perform trend analysis.

We do not have control over the Personal Data that you upload to Memsource, which means that various categories of Personal Data relating to various categories of Data Subjects may be processed in Memsource, depending on Your decision.

We may use the data that You upload to Memsource to train Our machine learning (ML) models in order to enhance Our services. The ML models transform the data into anonymous patterns that are then subject to algorithmic evaluation. Therefore, the data is never exposed to third parties using Memsource and neither is it possible to extract the data from the ML models. Upon the relevant request, the data is deleted within no more than 90 days and only the ML models remain. For more information visit our Artificial Intelligence and Machine Learning FAQ.

If you disagree with Us engaging another sub-processor, you may terminate this Agreement in line with these Terms of Service. Otherwise, it will be understood that you agree with Us engaging this new sub-processor;

  • before disclosing Personal Data to any sub-processor, enter into a contract with that sub-processor under which the processor agrees to comply with obligations equivalent to those set out in this clause (Your Content and Related Data Processing Operations);

  • remain fully liable to You for any failure of any sub-processor to fulfill its obligations under its contract with Us; and

  • before disclosing Personal Data to any of its employees and representatives, and the employees and representatives of each of its sub-processors, in each case who have access to the Personal Data, ensure that those persons are bound to hold the information in confidence to at least the same standard as required under this Agreement (whether under a written agreement or otherwise).
