Privacy

What Alerua does with information

Alerua LLC, an Arizona company, runs the website at alerua.com and the Alerua Radar apps for iPhone and Mac. There are no accounts, no sign-in, no advertising and no analytics services. You can reach us at zachary@alerua.com.

Before the map appears

The website asks Cloudflare Turnstile to confirm that your browser is not a bot. Cloudflare runs that check and handles the connection details it needs for it under the Cloudflare privacy policy, and it may set cookies of its own for the check. When the check passes, the site sets one cookie, alerua_web, which lasts two hours and says only that the check was passed. The site cannot work without it, and it is the only cookie we set.

Cloudflare carries our traffic

Requests to alerua.com and to the servers behind the apps pass through Cloudflare, which sees the address each request comes from and the page or picture it asks for. Cloudflare handles that under its privacy policy.

The map

The map comes from Mapbox. Your browser requests map tiles from Mapbox directly, so Mapbox sees your connection address and the area you look at, and its software may collect usage information. Mapbox describes this in the Mapbox privacy policy.

Your location

The website asks for your location only when you press the location button. The position is used to place a marker and move the map. It stays in your browser and is never sent to us.

The iPhone and Mac apps use your location on the device to show where you are and to find radars near you. A widget or the Mac wallpaper set to your location sends that position to our server so it can draw its picture. We do not write it to our logs and we do not tie it to you.

Our servers

Radar pictures, warnings and forecasts come from our own servers, which run in the United States. Like any web server, they log each request: the address it came from, the time, what was asked for and the kind of browser or app. We keep these logs for about a day, and no longer than a few days, to run the service, find faults and stop abuse. Our reason for keeping them is that the service cannot run safely without them.

We also keep daily and hourly totals of how the site is used: how many visits there were and which part of the site they used (the radar map, the forecast maps or the hurricane pages), which pages were viewed, which website or shared link led to the site if your browser says so, which country a visit came from as Cloudflare reports it, whether it was on a phone, a tablet or a computer, which radars, forecast maps and storms were viewed, and which features were used. They are counts, with nothing in them that identifies a person, and we keep them as long as they are useful.

Share links

A share link is a public picture: a radar’s recent loop, a forecast map, or a storm’s track. Anyone who has the link can open it. We count how often each kind of shared picture is opened, and by which kind of app, such as a chat app, a search engine or a browser, as the app names itself. We keep the kind of app, not who opened the picture.

The apps

The apps talk to the same servers, so the same server logs apply. We count how often the widgets and the Mac wallpaper refresh their pictures, with nothing that identifies a device or a person. The apps send no usage counts of their own. The maps in the apps come from Mapbox under the Mapbox privacy policy. Beta builds arrive through Apple’s TestFlight, and Apple collects crash reports and usage statistics for them under Apple’s terms.

What we do not do

We do not sell information, share it with advertisers, or build profiles of anyone. Alerua is for people 13 and older, and we do not knowingly collect information from children.

Your choices

Because there are no accounts, we usually cannot tell which log lines or counts are yours. If you want to see, correct or delete what we hold about you, or object to how we use it, write to zachary@alerua.com with the address you connected from and the time, and we will look. If you are in the European Economic Area or the United Kingdom, you have these rights under the GDPR and may complain to your data protection authority. If you live in California or another state with a privacy law, you have similar rights, and we do not sell or share personal information.
