Website Push Certificates expire after one year by default. When your current certificate expires, you can not only see in your account under Settings → Certificates → Apple Safari → Valid until, but Signalize will also remind you automatically.
Renewal before expiry is important because without a valid certificate it is neither possible to send push messages to Safari users nor to collect subscribers for iOS devices.
