What we collect and why

Your email: so you can log in, and (only if you turn it on later) to send price alerts.
Subscription names, prices, billing cycles, and dates you enter: to calculate your totals and spot possible savings.

We never ask for bank or card details. Your password is handled by our secure login provider and we never see it. Your data is stored in Canada. You can download or delete it at any time. Read the full privacy policy.

I agree to Castor collecting and using the information above for these purposes, as described in the privacy policy.
