Top Down · Version 2026-08-17

The short version

Top Down stores the coordinates of where you parked, and a token used to send you notifications. It does not know who you are, and it does not track where you go.

No account, no identity

Top Down has no signup. The app authenticates anonymously, which means we have no name, no email address, no phone number, and no way to identify you as a person. Your data is associated with an opaque identifier for your app installation and nothing else.

Reinstalling the app produces a new identifier. We have no way to connect the two.

What we collect

Data Why When
Vehicle coordinates (latitude/longitude) To know where to check the forecast Once, when you start a session
Approximate location accuracy To warn you when a fix is too coarse to be useful With the coordinates
Notification token To send you warnings When you grant notification permission
Device platform (iOS/Android) To format notifications correctly On first launch
Session times, lead-time preference To know when to stop monitoring When you start a session
Notifications we sent, and why So you can see your alert history When an alert fires
Crash reports To find and fix bugs that break the app Only when the app crashes

A crash report contains the error, the code path that produced it, your device model and OS version, and the roughly 5 km grid cell involved — never your precise coordinates, which are stripped before the report leaves your phone.

What we do not collect

How location is used

Your coordinates are reduced to a roughly 5 km grid cell before being sent to the weather provider, and the forecast is requested for the centre of that cell rather than your exact position. The weather provider therefore never receives your precise coordinates. Your exact coordinates are held in our database so the app can show you your pin.

Who else sees it

Provider What they get Why
Supabase All of the above (hosting our database) Infrastructure
Apple Weather A ~5 km grid cell centre, no identifiers Forecast data
Apple / Google / Expo Your notification token and the message Notification delivery
Sentry Crash reports, without precise location Diagnosing crashes

We do not sell your data, and we do not share it for advertising.

How long we keep it

Deletion is enforced by a scheduled job, not by policy alone.

Your choices

Children

Top Down is not directed at children and we do not knowingly collect data from anyone under 13.

Changes

Material changes bump the version and you will be asked to accept before creating another session.
