Data retention and deletion policy
Tailscale must retain certain kinds of data for a minimum amount of time, to comply with legal requirements. At the same time, Tailscale wants to avoid retaining any identifiable data for longer than is necessary, in case of a breach.
This policy applies to all data assets handled by Tailscale, including data from customers, potential customers, third parties, and employees.
Tailscale should review the data it retains as part of reviewing its data register quarterly.

*In response to a customer request and in compliance with legal requirements, Tailscale may also delete customer data prior to the end of the retention period.
Where not specified, customer data should be retained no longer than is needed to provide the service, and anonymized or deleted afterwards.
Data may be destroyed by overwriting on disk, deleting a cloud resource, encrypting and destroying the key, resetting a device, and/or physical destruction.
