3. Subject of the Contract, services provided by SIMSme

(1) SIMSme is an internet-based, cross-platform service for the secure exchange of messages between users of mobile end devices.

(2) The exchange can take the form of a single chat or group chat. The SIMSme user creates a message using the SIMSme app on their approved mobile device and then specifies the message recipients. The message is copied into the recipients' inbox and a push notification (based on the platform, for example, Apple Push Notification or Google Cloud Messages) is transferred with the information that new messages have been received and can be accessed.

(3) The messages are then available for the recipient to download. Each message is deleted on the SIMSme server immediately after it has been downloaded by the respective recipient, otherwise after 30 days.

(4) The user may specify that a message should self-destruct.

(5) The subject of the Contract is provision of the SIMSme service on a DPAG server and provision of related apps in the download portals of the various system platforms.

(6) The SIMSme system is designed on the basis of an end-to-end encryption concept, such that

i. no unencrypted information (document, document keys, document and folder names) is transmitted or stored on the SIMSme server,

ii. the key required to decrypt the documents does not leave the respective end device, and

iii. documents can only be read on the approved devices of the user and recipient. Any recipient may pass on the messages..

(7) Algorithms and methods considered to be secure according to the current state of the art (recommendations of the Federal Office for Information Security) are used for encryption .

(8) SIMSme is constantly developed with regard to the supported encryption algorithms, document formats, system platforms and functions. The current development status can be found in the current specification. DPAG always provides users with up-to-date apps to ensure the functionality of the system.

(9) Users can download and install an app for each of their end devices with their own telephone numbers. It is only possible to use the SIMSme service with one of these programs.

(10) Use of the programs requires setting up a user account on the SIMSme server. An end device with an updated app version and a valid mobile phone number is required to set up the user account.

(11) The SIMSme server and associated memory system are operated at a data centre in Germany which is certified according to ISO 27001 IT Basic Security. DPAG does not transfer any data abroad. This does not affect any transfers initiated by users to end devices being used abroad by other users.

(12) The SIMSme server does not store passwords. Authentication takes place exclusively on the released end devices of the user.

(13) The service may only be used for private purposes. Commercial use is prohibited and requires a separate license.

4. Registration

Upon registration, a SIMSme user account is created for the SIMSme user.

5. Conclusion of the contract

The user must first download and install the app onto their end device. When the app is opened for the first time, the registration process will start and the user will be asked to submit an offer to conclude a contract. DPAG accepts this offer by registering and activating the SIMSme user account.

DPAG does not provide any legal advice in this regard. It should be noted that complete security cannot be guaranteed through technical processes and that the security of encryption processes is subject to continuous change.

(3) The user is responsible for their activities, in particular for the messages attributable to the user which have been uploaded by third parties, stored in the system, held ready for retrieval and/or transmitted or distributed.

DPAG will specifically point out these consequences to users when it notifies them of the amendments.

(2) The invalidity of any provisions of these General Terms and Conditions will not affect the validity of the remaining provisions of these General Terms and Conditions. Invalid provisions will be replaced by provisions that most closely reflect the intended economic meaning of the invalid provision. The same applies in the event of any contractual gaps requiring remediation.

(3) The courts in Bonn have exclusive jurisdiction for legal disputes arising from or in connection with the use of the services or these General Terms and Conditions, and if the user is not a permanent resident of Germany or relocated their place of residence or habitual abode abroad after these General Terms and Conditions came into effect, or if their place of residence or habitual abode is unknown at the time at which the action is commenced.
