Information We Never Receive Nor Collect

Usage Data (including the date and time at which you use an application, the duration of using it, and other ‘metadata’) is NOT collected by Cypher Stack through the usage of the App. Cypher Stack has no reason to care about any aspect of your continued usage of our App. We believe that this data is your own property and that we have no right to collect it.

Data relating to your funds, and their security and privacy, remains on your device at ALL times. Your private keys and their associated view keys, seeds, backup files, and wallet passcode are your own responsibility. This data is not received, collected, or stored by Cypher Stack at any time, for any reason.

We receive this information:

This data is provided by connecting to the Nodes and price API maintained by Cypher Stack. You have the right to choose not to provide synchronization data to Cypher Stack by choosing a different Node. We provide a list of Nodes in the app that include our own and third party Nodes, or you can use your own Node (which we recommend).

Personal Data sent through the Cypher Stack Nodes is limited to your device’s IP address, the block height to which your wallet is synchronized, and any transactions or channels which you use our Node to submit to the supported cryptocurrency networks. Personal Data received by Cypher Stack in this manner is not stored for any length of time, and thus Cypher Stack is both unwilling to and incapable of sharing this data, or using it for any purpose beyond ensuring your appropriate connection to our Nodes.

If you decide to use a Node offered by any third party, some of which we include in our Apps, said third party will receive this Personal Data instead of Cypher Stack. We take no responsibility for the actions of any third-party Node offered within the Application. We recommend connecting to your own Node to limit third party sharing of your Personal Information.

Information We May Receive and Retain Temporarily

We receive but only store information temporarily for the following:

We maintain default server logs from our servers for 3 days so that we can detect error and crashes and any failures. These logs may contain your device IP’s address, but these aren’t linked to your activity on Cypher Stack’s Nodes. Logs that are older than 3 days are purged daily and are not retained.

We receive this information:

Information We May Receive and Retain

We maintain default logs on Cypher Stack Nodes for 3 days so that we can detect errors, crashes and any failures. Logs that are older than 3 days are purged daily and are not retained.

These logs may contain your device IP’s address. Your device IP’s address is compared against a locally hosted geolocation database to identify its country of origin and then purged immediately so that your device IP address is not logged, only aggregated data sorted by country. We use this information to understand where our customers are from and to improve localization and marketing efforts. We do not share this information with any third parties.
