Family plans

Paid subscribers of Ente can share the storage with their family, at no additional cost as you have already paid for the storage.

In breif,

Your family members can use storage space from your plan without paying extra.
Ask them to sign up for Ente, and then just add them to your existing plan using the "Manage family" option within your Subscription settings.
Each member gets their own private space, and cannot see each other's files unless they're shared.
You can invite 5 family members. So including yourself, it will be 6 people who can share a single subscription, paying only once.
