Hydrant Finder (the website at hydrantfinder.au and the iPhone and Apple Watch apps) is made by Resynthesis. In short: we use your location only to find the hydrants near you, we don't keep it, and we don't track you. Last updated 6 November 2026.

Your location and searches

When you let Hydrant Finder use your location, or search for an address, that position is sent to our server to find the nearest hydrants and measure the distance to them along the roads. We use it for that and nothing else. We don't store your location or your searches, and we don't link them to you.

To turn an address into a position, our server asks an address service (Photon, run by komoot, and OpenStreetMap's Nominatim). The request comes from our server, so those services see the address you typed but not who you are.

Counting how the app is used

So we know which features are worth improving, our server keeps totals, such as how many searches there were and how often Street View was opened, by day and hour, split by website, iPhone and watch.

To estimate how many different people use it each day, week and month, each visit is turned into a code that is scrambled one way with a random key, so it can't be turned back into anything about you. Codes are kept only until the day, week or month is over, then deleted along with their key; after that only the totals remain.

We also count roughly where visits come from, by country and, within Australia, by state. Our own server works this out from your IP address at the time of the visit; only the count is kept, and your IP address isn't stored or sent to anyone. Searches are counted by suburb only, never by address or position.

The website is open to visitors in Australia, North America and Israel. The same check on your IP address decides whether the website opens for you; nothing about it is kept.

We don't use cookies for any of this, we don't use advertising or advertising trackers, and we don't sell or share information about you.

Other services the app uses

• Street View pictures come from Google when you open them, under Google's privacy policy. Opening directions hands you over to Apple Maps or Google Maps.
• Maps: the website's maps come from OpenStreetMap and CARTO (through our server) and the Victorian Government's Vicmap; the iPhone and watch apps use Apple Maps.
• Hosting and protection: requests pass through Cloudflare and are served by DigitalOcean, and hydrant data is held in MongoDB Atlas. Like any web host, these providers handle your IP address to deliver and protect the service, under their own privacy policies. We don't keep logs of searches or locations.

On your phone or browser

A few settings, such as how many hydrants to show, aerial photos and the suburb for random spots, are saved on your own device only. You can clear them by deleting the app or your browser's site data.

Children

Hydrant Finder doesn't ask for or collect personal information from anyone, including children.
