Privacy notice

Privacy

Stroll>On is built so that there is very little to say here. There are no accounts, no advertising trackers, and the things that make the app yours stay on your own device.

Last updated 8 September 2026

The short version

Your goal, height, step length, preferences and saved walks are stored in your browser. We never receive them.
When you ask for a route, our server briefly sees your starting coordinates, the target distance and your route preferences. It uses them to answer, and does not store them.
There are no accounts, so there is nothing for us to hold about you.
No advertising or social trackers. Product analytics are off unless we turn them on, and would never include your location.
A shared walk lives in the part of the link after the # symbol, which browsers never send to a server.

Who we are

Stroll>On is a small independent walking app. For UK data protection law we are the data controller for the limited processing described below. If you want to ask anything about it, email hello@strollon.app and a person will read it.

What is stored on your device

Almost everything the app knows about you lives in your browser's local storage on your own phone or computer:

your daily step goal and the steps you have logged today;
your height, and the step length estimated or measured from it;
your unit preference, walking pace and route preferences;
any walks you save, and recent routes;
whether you have finished the short setup screens.

None of that is sent to us. It is not backed up to a server, which also means it does not follow you to another device, and clearing your browser data for this site deletes it permanently. You can do that at any time from your browser settings, or from the app's own settings screen.

What our server sees when you plan a route

Route planning is the one thing that has to leave your device. When you ask for a walk, the app sends our routing endpoint:

the coordinates you are planning from (your location, or a pin you dropped);
the target distance in metres, and how close counts as close enough;
your route preferences, such as prefer greener ways or prefer flatter;
whether you want a loop, an out-and-back, or a route to a destination.

That request is processed in the moment and thrown away. We do not keep a history of the places you have planned from, and because there are no accounts there is no profile for such a history to attach to. Our lawful basis for this processing is legitimate interests: you asked for a route, and we cannot produce one without knowing where you are starting from.

To build the route we forward the coordinates and distance to openrouteservice, our routing provider, which calculates walkable paths from OpenStreetMap data. They receive the start point and the shape of the request, and nothing about you, because we have nothing about you to send. Their own privacy policy governs what they do with it.

Server logs and abuse protection

Our hosting platform records ordinary technical information for each request, such as the time, the endpoint and the IP address it came from, and we apply a rate limit so one client cannot exhaust the routing budget for everybody else. These logs are short-lived and are used for keeping the service up and stopping abuse, not for analysing you. An IP address is personal data in the UK, which is why we mention it rather than pretending otherwise.

Sharing a walk

When you share a route, the walk itself is encoded into the part of the link after the # symbol. Browsers never send that fragment to a web server, so we do not see the routes you share, and neither does anybody else unless you send them the link. The person opening it does not need an account either.

Maps and other things loaded from elsewhere

The map is drawn with vector tiles from OpenFreeMap, which means your browser requests tiles directly from their servers as you pan and zoom. Those requests reach them rather than us, and they can see the tiles being requested and your IP address, as any server can. Map data is © OpenStreetMap contributors. Fonts are served from this site, not from a third-party font service.

Analytics and cookies

Stroll>On sets no advertising or tracking cookies, and there are no social media pixels. Product analytics — counting how often a feature is used, so we know what to improve — are switched off by default and log to the browser console during development. If we ever switch on a hosted analytics provider it will be a privacy-respecting, cookie-free one, it will not receive your coordinates or your step data, and this notice will be updated before it happens.

Children

The app is a general-audience walking tool and is not directed at children. Because there are no accounts, we do not collect anybody's date of birth or identity.

Your rights

UK GDPR gives you rights over your personal data, including access, correction, erasure and objection. In practice the data that makes up your Stroll>On is already entirely in your hands: you can see it, change it and delete it from the app or your browser settings without asking us. For the transient routing requests described above we hold nothing that could identify you, so there is nothing for us to hand over or delete. If you believe we have got any of this wrong, email hello@strollon.app. You also have the right to complain to the Information Commissioner's Office.

Changes to this notice

If what we do changes, this page changes with it and the date at the top is updated. For anything that materially affects your privacy we will say so in the app as well as here.
