A lot of apps start with a login screen. Where Sun starts with a sun. That is not just a design choice. It is a product choice. You should be able to open the app, search a city, compare a few places, and leave with a plan.
No account means less to protect
If we do not ask for an account, we do not have a password to secure, a profile to store, or a user database to defend. That keeps the app simpler for you and simpler for us. There is no username to remember and no inbox confirmation before you can see whether the beach looks better than the city.
Saved places live on your device. The app does not need to know your personal travel habits to be useful.
Location is optional
Current location can make the app faster, but it is not required. You can type any city manually and use Where Sun that way. That matters because privacy is not just a policy page. It is the ability to use the product without saying yes to everything.
So what does touch a server?
Weather and place data have to come from somewhere. Where Sun uses external data sources to fetch forecasts, maps and nearby places. A lightweight Cloudflare Worker helps protect API keys and keep direct provider secrets out of the app bundle.
That is different from running a social backend or storing your personal saved places. The server-side layer exists to make the app function safely, not to turn users into accounts.
Subscriptions without creep
Premium is handled through Apple and RevenueCat. That lets the app unlock paid features without building our own payment identity system. The goal is simple: free users can use the app, premium users get expanded limits, and nobody needs a Where Sun password.
Why this matters
Weather is intimate in a quiet way. It reveals where you are, where you might go, and what kind of day you are trying to have. We do not need to own that. We just need to help you make a better plan.
