1. Preamble

Datapods GmbH (hereinafter “Datapods”) provides you, the user (hereinafter “User”) with the Stack App, a free data management application (hereinafter “Stack App”) with which you can manage your personal data with third-party companies. In accordance with the following User Agreement, the Stack App offers the services listed in section 3.

Our mission with Datapods is to provide an app which allows you to, by downloading, playing and completing tasks in certain apps, answering surveys, scanning receipts, and providing your user data from certain third-party companies for visualization in the Stack app and for the generation of statistical, non-personal insights for our Customers, receive rewards.

You can also join the separate Data Monetization Platform to have Datapods monetize your data directly.

Datapods places the highest value on data security and data protection and works in accordance with the strict requirements of the European General Data Protection Regulation (GDPR) and the Federal Data Protection Act (BDSG) and high security standards. You can find out more in the Privacy Policy for the Stack App.

2. General information and scope of application

2.1 Datapods shall provide services to users of the Stack App in accordance with this User Agreement.

2.2 If Datapods offers the services offered to the User jointly with Cooperation Partners (see section 7), additional Terms of these Cooperation Partners shall apply where applicable.

2.3 The Terms and Conditions shall apply exclusively. Any terms and conditions provided by you that conflict with or deviate from this User Agreement shall only become part of the contract if they are consistent with the content of these Terms and Conditions or have been expressly acknowledged by Datapods in writing. This shall also apply if Datapods provides services to you without reservation in the knowledge of conflicting or deviating terms and conditions.

3. Services of the Stack App

The services of the Stack App are as follows:

Initial and ongoing retrieval of personal data from third-party companies;
Data analyses based on the personal data in the Stack App;
Providing a feature that allows users to earn rewards by playing third-party games through our partner adjoe;
Providing surveys through which users can earn rewards via our partner, CPX Research;
Providing a scanning functionality for receipts with which users can earn rewards;
Providing the Data Monetization Platform for sharing data in return for remuneration on the basis of a separate user agreement;
Providing support for you to answer your questions in accordance with this User Agreement and the separate Privacy Policy.

4. Provision of the services

The provision and performance of the services of the Stack App listed under section 3 are specified in more detail below. The access requirements and usage rules for the individual functions additionally follow from section 5 and section 8.

4.1 Data Analysis

4.1.1 Within the scope of the Data Analysis, after your authentication to the relevant Data Interface (see section 8.2), Datapods retrieves the personal data stored about you at third-party companies (e.g. usage data, shopping carts, location data, search histories, purchase history), structures and categorises it and displays it to you – directly or as insights derived from it – in the Stack App. This requires that you have previously accepted this User Agreement and had the opportunity to take note of the separate Privacy Policy.

4.1.2 Where YouTube data is visualised, this may require the retrieval of contextual data via the YouTube API; in this respect, YouTube's Terms of Use shall additionally apply, to which you have already agreed by using YouTube.

4.2 Rewards through games and surveys

4.2.1 Through our partner adjoe, you can earn rewards by downloading, playing and actively using third-party apps and games. The reward arises in accordance with the tasks specified by adjoe (e.g. game progress or duration of use).

4.2.2 Through our partner CPX Research (Make Opinion GmbH), you can earn rewards by participating in surveys and completing them in full and in qualified form.

4.2.3 adjoe and CPX Research each act as independent controllers. The details regarding requirements, consents and permitted use follow from sections 5.3 and 5.4 as well as section 8.9.

4.3 Rewards through receipt scans

Through the scan function, you can earn rewards by submitting receipts from your own purchases. Datapods records the information contained on the receipt (e.g. retailer, items, amounts, date) and credits you with a reward after successful verification. The details regarding permitted use and verification follow from section 5.5 as well as section 8.9.

4.4 Multiplier through the addition of data sources

4.4.1 You may voluntarily add data sources in the Stack App by granting Datapods access, via the relevant Data Interface, to the data stored about you at third-party companies (see section 4.1). For adding data sources, you receive a multiplier that increases the amount of the rewards you earn through adjoe and CPX Research. Which data sources lead to which multiplier is shown to you in each case in the Stack App.

4.4.2 Datapods uses the data provided via the added data sources in order to create statistical, non-personal analyses and insights in aggregated and anonymised form and to provide them to Datapods' customers. In this context, your data is not passed on or sold as personal data to third parties; the multiplier is the consideration for providing the data sources for this purpose.

4.4.3 The processing of your personal data up to the point of anonymisation takes place in accordance with the separate Privacy Policy. Insofar as you additionally wish to carry out individual transactions involving personal data (e.g. the licensing of your data to cooperation partners in return for remuneration), this is governed exclusively by the separate User Agreement for the Data Marketing Platform and is not the subject of this User Agreement.

5. Access and availability

5.1 In order to use the services of the Stack App, you must be of legal age and legal capacity.

5.2 The provision of the Data Analysis requires that you have a user account with an interface-enabled third-party company as well as your authentication to the Data Interface. For this purpose, you must know its authentication data (see section 4.1.2).

5.3 adjoe is the independent entity responsible for providing third-party apps and games, and its terms and conditions and privacy policy apply in addition to ours (see Section 2.2). Rewards will only be credited if adjoe reports the respective task to Datapods as validly completed. Datapods has no influence over the availability or confirmation of tasks.

5.4 CPX Research is the independent entity responsible for providing surveys, and its terms and conditions and privacy policy apply in addition to ours (see Section 2.2). A reward will only be credited if CPX Research confirms that the survey has been completed in full and meets the eligibility criteria. There is no entitlement to a reward for ineligible or abandoned surveys.

5.5 The scan function, which allows you to earn rewards by submitting receipts, may only be used with genuine, legible receipts from your own purchases; a reward may be claimed only once per receipt. You warrant that the submitted receipts are authentic and unaltered. Datapods shall be entitled to check submitted receipts, to reject illegible or manifestly inadmissible receipts and, in such cases, not to credit a reward.

5.6 Datapods shall be authorised to change or modify the services of the Stack App in accordance with section 13.2 of the User Agreement.

5.7 Datapods shall endeavour to make the Stack App available without interruptions. However, no liability can be accepted for temporary unavailability of the Stack App. Datapods may temporarily restrict availability if this is necessary with regard to capacity limits, the security or integrity of the servers or to carry out technical maintenance or repair measures and this serves the proper or improved provision of the services (maintenance work). In these cases, Datapods shall take into account your legitimate interests, e.g. by providing advance information. The liability of Datapods due to fault in accordance with section 12 shall remain unaffected.

6. Conclusion of contract

6.1 By registering a user account after downloading the Stack App, you submit a binding offer to conclude a contract for the processing of your data and the provision of the services of the Stack App in accordance with this User Agreement and the separate Privacy Policy for the Stack App by Datapods.

6.2 “IP Rights” means all intellectual and industrial property rights, whether registered or unregistered, whether created by Datapods or acquired from third parties, and similar rights, including (but not limited to) copyright, design rights, trade mark rights and all applications or claims to such IP rights.

6.3 Datapods grants you a non-exclusive, worldwide, non-transferable and non-sub-licensable license, limited in time to the duration of the User Agreement resp. the Subscription and revocable at any time, to use the App content protected by IP Rights. This right of use includes in particular the right to save, load and display the App in order to use the functions and services of the App.

6.4 Any other use of the App content, in particular for text or data mining in accordance with section 44b of the German Copyright Act (UrhG), is not permitted.

7. Collaboration with Cooperation Partners

If you conclude the separate User Agreement for the Data Monetization Platform with Datapods within the Stack App, Datapods will market your data to Cooperation Partners on the basis of your granular consent settings.

8. Cooperation and other obligations of the User

8.1 You are obliged to provide reasonable co-operation in the use of the services of the Stack App.

8.2 In particular, you authenticate yourself to the Data Interface with your login data from third-party companies (e.g. user name and password) and assure that you are authorized to use the interface and comply with any provisions of the third-party companies.

8.3 You shall not register a account that is owned by another individual in the Stack App.

8.4 You shall not circumvent any security functions of the Stack App and shall refrain from attempting to do so.

8.5 You must ensure the confidentiality and security of your access data for the Stack App and the services used through it. You must keep your access data secret, must not pass it on, must not tolerate or allow third parties to gain knowledge of it and must take the necessary measures to ensure the confidentiality of your access data, e.g. by using a secure PIN that does not match any other PIN. You must keep your mobile phone safe from access by third parties.

8.6 If you discover the loss or theft, misuse or other unauthorised use of your access data, you must inform Datapods immediately. Any theft or misuse must be reported to the police immediately. If you suspect that another person has gained unauthorised possession or knowledge of your access data or is using your access data, you must also inform Datapods of this immediately.

8.7 The data analysis within the Stack App are based on the data you provide. You or the third party company providing the data is therefore jointly responsible for the completeness and accuracy of the data provided to Datapods and the result of the processing of this data by Datapods. If there are indications that the data and information provided by you is or could be incorrect, Datapods shall have the right not to process the order placed. Datapods shall inform you of this.

8.8 If you breach your obligations under this User Agreement, Datapods is entitled to terminate the affected services of the Stack App, not to perform the desired service, and not to credit rewards.

8.9 When using the reward functions (sections 5.3 to 5.5), you shall provide only truthful information and shall refrain from any manipulation, in particular the use of multiple user accounts, the use of bots, emulators or automation tools, the concealment of location or device, and the repeated submission of the same receipt or the submission of third-party or forged receipts.

8.10 Rewards obtained in breach of this User Agreement or through manipulation, false information or deception shall be deemed not to have been validly acquired. Datapods shall be entitled to reverse or reclaim such rewards and, in the event of repeated or serious breaches, to block the affected user account.

9. Costs and payment modalities

9.1 Datapods offers Users the basic functions of the Stack App, including participation in the Data Monetization Platform, free of charge.

9.2 You may receive rewards (“Rewards”) for activity on the Data Monetization Platform, i.e. setting permissions, referring new users to the app, providing data, and the marketing of data, e.g. for the successful conclusion of Data License Agreements in which your data is included as part of the data packages provided or for sales of Analysis Products in which your data is used.

9.3 The Reward that you can receive for the specific contribution of your data in a data package will be displayed in the overview of the individual Data Transactions.

9.4 A Reward will only be awarded to Users who follow all instructions regarding the cooperation and other obligations regarding the provisions of the services of the Data Monetization Platform. A Member's failure to correctly follow any such instructions or procedures may result in no Reward being awarded.

9.5 Rewards will be recorded in your Stack Account, however Rewards are not available for redemption until a User has (subject to paragraph 9.7 below) reached the specified fulfilment level in their Stack Account.

9.6 If Datapods has suspended or terminated your Stack Account for any of the reasons outlined in these Terms any Rewards you have been awarded cannot be redeemed and may be forfeited. Datapods reserves the right to reclaim any Rewards held in the Stack Account or paid to the User following breach of these Terms.

9.7 Datapods is not obligated to include your data in data packages for which you can receive Rewards and can vary the frequency of using your data for such marketing activities. Datapods also reserves the right to alter the specified fulfilment level before Rewards may be redeemed.

9.8 Rewards have no monetary or other value. Rewards may not be transferred to other Stack Accounts nor pooled together in any manner and the sale or barter of Rewards is strictly prohibited.

9.9 Datapods may, in our reasonable judgement, adjust the Rewards in a Users's Datapods Account upwards or downwards in response to errors (which Users acknowledge may arise) or if Datapods suspect fraud.

9.10 Datapods may exclude any Stack Account that has been dormant for a period of 12 months or more from the Data Monetization Platform. Any unused Rewards will be forfeited. By “dormant” we mean that a User has not been active on the Data Monetization Platform within the previous 12 months, i.e. they have not set or changed any permissions, their data has not been included in any marketed data packages and they have not updated their data. Datapods may contact the User via their nominated contact details if their Stack Account is at risk of termination through inactivity.

9.11 You are responsible for the correct and complete provision of the data required for the payout.

9.12 Payouts also require that you verify your identity at our request by means of 2-factor authentication, e.g. by entering a code sent to you and that you identify yourself to any payment service provider in the manner provided by the latter.

9.13 The remuneration is valid for one year, starting at the end of the calendar year in which the Reward was awarded to your account. At the end of the validity period, the respective Reward expires automatically.

9.14 Remuneration acquired first is paid out first.

9.15 You can view the Rewards awarded to your account in the Stack App.

10.4.5 In the event that commercial use of the Refer-a-Friend program or public dissemination by the Existing Customer becomes known to Datapods only after credit of the Bonus, Datapods may demand the credited Reward or paid out amount back from the Customer and, if necessary, charge it back.

11. Data protection

Datapods collects, processes and uses your personal data primarily in order to provide the services of the App or Platform as well as our partners in accordance with this Agreement. Any further use will only take place if there is a basis for processing. In order to be able to use the Stack App without restriction, your consent to the use of your personal data is required.

For details, please refer to the separate Privacy Policy for the Stack App, which is available on the Datapods website and can be accessed there at any time.

The Privacy Policy for the Stack App also expressly contains your right to withdraw consent in whole or in part at any time. The withdrawal of consent shall not affect the lawfulness of processing based on consent before its withdrawal. However, in the event of full or partial withdrawal, it is possible that you may not be able to continue to use the Stack App in full or in part.

12. Liability

12.1 Claims for damages are excluded. Excluded from this are claims for damages against Datapods arising from injury to life, limb or health or from the breach of material contractual obligations (cardinal obligations) as well as liability for other damages that are based on an intentional or grossly negligent breach of duty by Datapods, its legal representatives or agents. This shall also apply to indirect consequential damages such as, in particular, loss of profit.

Material contractual obligations (cardinal obligations) are obligations that Datapods must fulfil in accordance with the content and purpose of this Contract and its addenda, the fulfilment of which is essential for the proper performance of this Contract and on compliance with which you regularly rely and may rely. The essential contractual obligations of this Contract include in particular, but not exclusively, the services listed in section 3. The uninterrupted technical availability of the Stack App is not an essential contractual obligation of this contract.

12.2 In the event of a breach of material contractual obligations (cardinal obligations), Datapods shall only be liable for the foreseeable damage typical of the Contract if this was caused by simple negligence, unless your claims for damages are based on injury to life, limb or health.

12.3 The limitations in sections 12.1 and 12.2 of the User Agreement shall also apply in favour of Datapods' legal representatives and agents if claims are asserted directly against them.

12.4 The limitations of liability resulting from Sections 12.1, 12.2 and 12.3 of the User Agreement shall not apply if Datapods has fraudulently concealed the defect or has assumed a guarantee for the quality of the item. The same shall apply if Datapods and you have entered into a quality agreement.

12.5 The provisions of the Product Liability Act shall remain unaffected by the provisions in this section 12 of the User Agreement.

12.6 If Datapods arranges third-party services (which are expressly and clearly labelled as such, stating the identity and address of the third party) at your request or commissions them in your name and for your account, Datapods shall not be liable for the services or work results of the third party concerned. In such cases, Datapods shall only act as an intermediary. The respective third parties are not vicarious agents of Datapods.

12.7 Datapods shall be liable for the loss of data and programmes and their recovery to the extent set out in this section 12 and only to the extent that this loss could not have been avoided by taking reasonable precautions, in particular by making backup copies of all data and programmes.

12.8 Datapods shall not be liable, subject to the limitations in Clauses 12.1, 12.2 and 12.3, for failed data retrievals or access restrictions caused by a third-party company or due to breaches by you of the user agreements that you have concluded with a third-party company or which are based on circumstances beyond our control.

12.9 You are obliged to notify Datapods immediately in writing of any damage within the meaning of the above liability provisions or to have it recorded by Datapods so that Datapods is informed as early as possible and can possibly minimise the damage together with you.

13. Termination

13.1.1 Datapods may also terminate the entire business relationship or individual business relationships for which neither a term nor a different termination provision (see section 13.2) has been agreed at any time, subject to a reasonable notice period. When determining the notice period, Datapods shall take into account your legitimate interests.

13.1.2 Termination of the entire business relationship or individual business relationships without notice shall be permissible if there is good cause that makes it unreasonable for Datapods to continue the relationship, even taking into account your legitimate interests. Good cause may exist in particular if the statutory or regulatory requirements for the provision of or in connection with the services of the Stack App change. If the good cause consists of the breach of a contractual obligation, the termination shall only be permissible after the unsuccessful expiry of a reasonable period of time set for remedial action or an unsuccessful warning, unless this is dispensable due to the particularities of the individual case (Section 323 para. 2 and 3 of the German Civil Code).

13.1.3 Subject to a separate agreement, you shall be entitled to terminate the entire business relationship with Datapods at any time without notice. For this purpose, you may irrevocably delete your user account within the Datapods App.

14. Miscellaneous

14.1 Applicable law

14.1.1 This User Agreement and all contracts and contractual rights and obligations concluded between Datapods and you including these Terms and Conditions shall be governed by the laws of the Federal Republic of Germany, excluding the United Nations Convention on Contracts for the International Sale of Goods.

14.1.2 All non-contractual rights and obligations arising out of or in connection with this User Agreement shall also be governed by and construed in accordance with the laws of the Federal Republic of Germany.

14.1.3 The statutory provisions restricting the choice of law and the applicability of mandatory provisions, in particular of the country in which you as a consumer have your habitual residence, remain unaffected.

14.1.4 If you are a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction for all disputes arising from contractual relationships between you and Datapods shall be the registered office of Datapods.

14.2 Changes to the User Agreement

14.2.1 In the case of continuing obligations, Datapods shall have the right to amend these Terms and Conditions insofar as this is necessary for the reasonable continuation and performance of the contractual relationship for the reasons listed below,

14.2.2 The contract shall remain binding in its remaining parts even if individual points are legally invalid. The invalid points shall be replaced by the statutory provisions, if applicable. However, if this would constitute an unreasonable hardship for one of the contracting parties, the contract as a whole shall become ineffective; or

14.2.2 to fill existing and arisen gaps in the contract if an existing or arisen gap in these Terms and Conditions after conclusion of the contract causes not insignificant difficulties in the execution of the contract (e.g. case law declares a clause invalid) and this cannot be remedied otherwise; or

14.2.3 to adapt these Terms and Conditions to changes in the legal situation (e.g. changes to the relevant laws or Federal court rulings), insofar as this is necessary to ensure the legality and other legal conformity of these Terms and Conditions and of performance and consideration; or

14.2.4 to restore the equivalence of performance and consideration if this is disturbed to a not insignificant extent after conclusion of the contract by unforeseeable changes to the legal or other framework conditions (e.g. by changes to the law, unless their specific content was already foreseeable – for example in the phase between the conclusion of the formal legislative procedure and their entry into force). This only applies if Datapods does not initiate these changes and has no influence over them.

14.2.5 You will be notified of the amended Terms and Conditions in writing or by email before the planned effective date of the Terms and Conditions. In the case of consumers within the meaning of Section 13 BGB, an explanation of the changes will be provided.

14.2.6 You may terminate the contract affected by the change without notice and free of charge on the proposed date on which the changes take effect. You will be specifically informed of this in the notification.

14.2.7 The provision in clause 14.2.1 does not include any changes that affect prices.

14.2.8 The contract shall remain binding in its remaining parts even if individual points are legally invalid. The invalid points shall be replaced by the statutory provisions, if applicable. However, if this would constitute an unreasonable hardship for one of the contracting parties, the contract as a whole shall become invalid.
