# CVG 1.15.0 (05-Oct-2021) Our new release brings an important improvement in the **protection of end users' personal data**: If it is not necessary for a bot and bot developers to know the customer's phone number, CVG can now anonymize it. I.e. Conversational AI like Boost, Cognigy, Dialogflow, Rasa, Ubitec, other API consumers and integrations will only see an anonymized phone number. Another privacy feature is that you can **restrict access to the recordings** transferred to VIER Interaction Analytics by specifying roles. We have again made some improvements to the user interface to make your life easier. Last but not least, our CVG console is now available in **German**!  ## Optional Anonymization of Customer Numbers In order to respect your users' data protection rights we now offer the ability to anonymize phone numbers before they are transferred to external systems (bots, integrations, API consumers). If *Anonymize Customer Phone Numbers* is enabled, CVG will hash the remote caller ID when communicating with bots and other services. The hash is _deterministic_: the same phone number will produce the same hash so that different customers can still be distinguished. For instance, bots could use this to react differently to a customer that is calling a second time. Hashed phone numbers can be identified by the keyword `md5-hash:` at the start of the string (for example `"remote":"md5-hash:ad14c520b9cfc53c25f446b338c79ced"` instead of `"remote":"+49111111111"`). The anonymization can be enabled in the new **Data Protection** sections in the customer, account and project settings. In the project form it's part of the advanced options below *Call Recordings*. More details on how hierarchical settings like this work can be found [here](/docs/core-concepts.html#hierarchical-settings). [](/docs/_images/data-protection-settings.png) This affects the following fields in our APIs: - `SessionParameters.remote` in the [Bot API](/specs/?urls.primaryName=Bot%20API%20(Client)) - `CallStarted.callerNumber` in the [Webhook API](/specs/?urls.primaryName=Webhook%20API) In CVG itself we need to store the phone numbers of the callers un-hashed due to billing and legal reasons. ## Integrations ### Roles for VIER Interaction Analytics If the "VIER Interaction Analytics" integration is activated, recordings of your CVG project are automatically transferred to your "VIER Interaction Analytics" project. To ensure that only users with certain roles can view these recordings and analytics results, these roles can be specified in CVG with the integration "VIER Interaction Analytics".  You can enter multiple roles by pressing [ENTER] before adding a new role.
Roles need to be defined in your VIER Interaction Analytics account
Please make sure to only specify roles that are defined within your VIER Interaction Analytics account.
For moving projects you need access rights for more than one account.
This feature can only be used by users with customer- or reseller-level permissions.
Retention period for deleted items
We have not changed the retention period for deleted items. It is 90 days. After that, the item is irretrievably deleted.
