In this context, slice’s authors transform the key insights of expert knowledge formats, such as video, audio, written and other content for you into summarised video, audio & presentations. The summarised format is called slice. This gives you the option to grasp the key insights from experts or other content on your computer or mobile device, in the shortest possible time.

Further, slice supports Keynote Speakers, Coaches, Entrepreneurs/CEOs, and corporates with consulting and lead generation/sales services.


The use of the platform (including the apps) shall be subject to the following General Terms and Conditions (“General Terms and Conditions”) in the version valid at the time of registration or order. slice does not acknowledge any different general terms and conditions belonging to you unless slice agrees to their validity in writing.


No separate contract text is provided for the Agreement pertaining to the use of the platform. The content of the agreement between you and slice is based on these General Terms and Conditions, as well as on the specific information provided as part of the registration (see Section 3) and by signing up for a paid subscription (Section 4), that will be saved by slice and that is available in your user account at any time.


You accept the validity and applicability of these General Terms and Conditions by registering and/or purchasing a paid subscription, as the case may be.


2. slice’s Services and Rights


slice provides the key insights from expert videos, audio, articles and other content (for e.g., the "slices", known together as ”Platform content”), which allow you to grasp their essence within a few minutes. Moreover, slice may provide a personal profile to you, which you can fill with your preferred platform content and text markers as well as sorting this content into different categories and lists.


The extent of the material of the platform content and the options to use (the “License”) depend on the type of account you selected. There is a difference between a free account (see Section 3), a paid subscription (see Section 4). In terms of duration, the license is limited to the validity period of the free account / paid subscription. The rights to slice's service and the content distributed through the service are and will remain with slice and /or slice's licensors. The slice software applications and content are licensed to you under the terms of the user agreement. We only grant you a non-exclusive (simple), time-limited right to personal use of the slice service and its contents.


All slice trademarks as well as our trade names, logos, domain names and other distinctive features of the slice trademark are the sole property of slice. The license does not give you any right to use the slice trademarks, our trade names, logos, domain names or any other distinctive features of the slice trademark, be it for commercial or non-commercial purposes. If you do not use a paid service, slice is allowed to show you promotional information on the platform.


3. Registering with slice


In order to be able to use slice’s paid services or presentations, a registration with slice is required. Individuals over the age of 18 have the right to register. As a minor, you may only register with slice if you are at least 14 years old and your legal representatives have provided their consent. We have the right to make the use of slice services contingent on proper proof of your identity, your legal age, or your legal representative’s consent.


The registration itself for presentations is free of charge (free account) and does not make you sign up for a paid subscription. By registering, you are executing an agreement with slice for a limited, free use of the presentation platform.


You can use your e-mail address as well as a password of your choice to register. Alternatively, you may register using a single sign-on service (for example, Google login). You can register via our website.


Any information required for registration must be complete and correct and always up-to-date. slice has the right to save and process the data you provided during registration, in accordance with the provisions on Data Protection.


The password used must be kept confidential. Keeping it a secret is solely and fully your responsibility. The slice user account may only be used by you. Any unauthorized use of your user account, as well as any such suspicion to that effect should be communicated to slice immediately.


4. Executing an Agreement for a Paid Subscription


To be able to fully benefit from slice's services, additional service packages in the form of paid premium packages, monthly or value based packages (e. g. lead generation package for 3 months, single videos transcription, audio albums) or subscriptions (“Premium/Subscription access”) will be made available to you after registering. These can be purchased for different, and variable periods of time, which you will see in the order options.


slice's subscriptions are ad-free, paid subscriptions that allow you to access additional content and features through our mobile and web-based applications. We currently offer the following subscription / service package:


The slice Premium service package includes ad-free access to all of our content in video, audio & presentation format. You will have access to the respective services as long as your subscription is valid.

You submit a legally binding offer for a fee-based subscription, if you enter the information requested in the online order form and then click on the “Order with obligation to pay” button. By doing so, you submit a legally binding offer for an agreement for a paid subscription. Before submitting your order, you may change and view the data at any time.


The agreement is accepted when slice issues a notice of acceptance, which will be sent to you immediately by email (receipt and order confirmation). In this email, the text of the agreement (consisting of the order, terms and conditions and order confirmation) will be sent to you by slice on a permanent data carrier (email) (agreement confirmation). Your subscription begins on this date. The text of the agreement is saved subject to data protection. Please read our Privacy Statement for information on the collection, use and processing of your data.


5. Trials/Testing Phases


slice occasionally offers new users in particular, free subscription access for testing purposes for a certain period of time (“Trial”). slice determines, at its sole discretion, if you may participate in a trial. slice may discontinue or change such free trial at any time without prior notice or notification, upon providing an important reason.


You can only participate in certain trials if you enter your payment details when you sign up for the trial. In these cases, we need your consent at the beginning of the trial for the fact that your free access will switch to a paid subscription access (Section 4) after the trial ends, on the day following the end of the trial. In this situation, your subscription renews itself on a recurring basis and can be terminated up to one day before the end of the respective subscription period (Section 8 (2)).


If, in a situation similar to the description in Section 5 (2), you do not wish to have the subscription access and the charge associated with it, you must cancel your subscription access given to you during the trial (for example, by simply going to your slice Account Settings or respective app store settings) before the end of the trial.


For subscriptions made on our website (Section 4) and with a term of at least one year, we provide a 14-day money back guarantee. For subscriptions completed as in-app purchases (Section 4 (7)), we cannot control the refunds and therefore cannot guarantee a refund within 14 days.


6. Cancellation Policy


If you are a consumer (i.e., a person completing the legal transaction for purposes that can be predominantly attributed to neither their commercial nor their independent professional activity), you are entitled to a legal withdrawal right when executing a distance selling agreement, so in this case when signing an agreement for a fee-based subscription with slice, about which slice informs below, as per the requirement of the statutory model.

As part of your subscription, your payment obligation to slice will, if selected, be automatically renewed at the end of the relevant subscription term if you do not cancel your paid subscription at least 24 hours before the end of your term (Section 8 (2)). This does not account e. g. for purchase of single premium or value packages.

8. Term / Refund / Cancellation Policy



1. Business Model / Strategy / Consulting

2. Lead Generation & Sales

3. Content Solutions (Micro Content / Video / Audio)


Payment for all services is to be conducted upfront on a monthly basis, or package basis, depending on agreement between slice & the client.


No refunds are available for completed services.


No refunds are available for any agreed project length, incl. minimum length trial period, e. g. If agreement is a value package for a minimum 3 month period: client cancellation will not result in right for a partial refund. Also in this case, no refunds are available.  

Unused, pre-paid and retainer-based consulting services may be eligible for a refund depending on the agreement between client and slice. 


Standard notice for cessation of services is one calendar month, in certain occasions it may be 14 days.


– There is no cash refund.

There is no refund for merely changing your mind!

– We are here to get you results and these results cannot be achieved if you fail to commit to your part of the agreement!

– This is not negotiable. 

Both slice (zipstrr GmbH) and the subscriber/client have the right to terminate the collaboration/contractual agreement without notice for a good cause. In either case, no party is entitled to any kind of refund.


A good cause entitling slice to the termination of the contract without notice occurs if


a) the Client’s behaviour endangers existing contractual relationships with other clients

b) the Client’s behaviour interferes with standard operations / processes & procedures on the side of slice and puts significant harm to their performance

c) the Client delayed with two (2) successive monthly instalments

d) the Client declares insolvency, especially in the case of opening insolvency proceedings due to a lack of mass (insolvency, cessation of payments or suspension or dissolution of the business activities – for whatever reason- shall equal insolvency)


9. Liability


slice disqualifies any claims for damages coming from you. This does not apply to claims for damages arising from fatal injuries, physical injuries, health damage or from the breach of essential contractual obligations (cardinal obligations) as well as liability for other damages that are based on an intentional or grossly negligent breach of duty by slice, its legal representatives or affiliates. Essential contractual obligations are those the fulfillment of which enables the proper execution of the Agreement in the first place and on the fulfillment of which you can trust.


In the event of a breach of essential contractual obligations, slice shall only be liable for the typical, foreseeable damages stipulated in a contract, if they were simply caused by negligence, unless it also involves claims for damages due to fatal injuries, physical injuries or damages to health.


The restrictions mentioned in Section 10 (1) and 10 (2) also apply to breaches of duty by slice’s affiliates and legal representatives, if claims are made directly against them.


10. Change of Terms and Conditions


slice reserves the right to make changes to individual clauses of the General Terms and Conditions with effect in the future, by taking into account slice’s interests and provided it is reasonable for you. If no explicit consent is obtained from you to adapt the General Terms and Conditions, you will be notified by slice of any changes to the terms and conditions in a timely manner (at least four weeks before the amended General Terms and Conditions enter into force). To this end, slice will send you the new version of the General Terms and Conditions to the e-mail address specified by you in the registration. In this context, slice will expressly point out to you the possibility and deadline for objections to the change, as well as the consequences, should you refuse to submit an objection.


If you do not object to the change within six weeks after the effective date of the amended General Terms and Conditions, the amended GTC shall be deemed accepted. The deadline starts on the date you are notified by email as being the effective date of the change.


If you object to the change, slice has the right to terminate the User Agreement with effect from the day the amended Terms of Use enter into force and cancel your User Account, in the event that adherence to the contractual relationship under the validity of the existing General Terms and Conditions is not possible or reasonable, taking into account your interests.


11. Out-of-Court Dispute Resolution


For the out-of-court resolution of consumer disputes, the European Union has set up an Online Dispute Resolution (“OS Platform”) platform that can be accessed at The platform serves as a point of contact for the out-of-court resolution of disputes concerning contractual obligations arising from online agreements. According to § 36 VSBG [Verbraucherstreitbeilegungsgesetz, Consumer Dispute Resolution Act], slice points out that slice is neither obligated nor willing to participate in a dispute resolution procedure before a consumer arbitration board.


12. Final Provisions


If any provision of these General Terms and Conditions is invalid, the remainder of the agreement remains valid. The statutory provisions shall take effect over the invalid regulations.


The law of the Federal Republic of Germany shall apply, excluding the provisions of the UN Convention on Contracts for the International Sale of Goods (CISG). The legal provisions restricting the choice of law and the applicability of mandatory regulations, in particular of the state in which the customer normally resides as a consumer, remain hereof unaffected.


If no exclusive legal court of jurisdiction is given, all disputes arising out of or in connection with the contractual relationship shall be settled exclusively by the court at slice’s registered office, thus Berlin, provided that you are a merchant, a legal entity under public law or a special fund under public law or have no general court of jurisdiction in Germany or another EU member state, or have moved your (residential) address to non-EU countries subject to the validity of these General Terms and Conditions.
