Privacy policy

ardeo · Last updated 23 September 2026

ardeo records prayer walks. Recording a walk means recording where you walked, which is sensitive, and this policy exists to say plainly what happens to that information.

We are based in New Zealand and handle personal information under the Privacy Act 2020.


The short version


What ardeo records

Location. While a walk is recording, ardeo reads your phone’s GPS position repeatedly. This is the core function of the app and cannot be turned off while recording, though you can pause or stop at any time.

ardeo does not read your location when you are not recording a walk. There is no tracking between walks.

If you turn on background recording, the app keeps recording while your screen is off, while you are in other apps, and — on Android — after the operating system shuts it down or the phone restarts mid-walk. That is asked for separately from basic location permission, and it has its own setting, because it is a bigger thing to agree to.

Steps. If your phone has a step counter, ardeo reads it during a walk and shows the count in the walk summary. Steps never affect the recorded distance.

Walk statistics. Distance, duration, moving time, start and end times.

Coverage areas. Your route is converted, on your phone, into a grid of hexagons roughly 65 metres across. These record that you passed through an area, not the path you took through it.

What you write. A note on a walk, up to 600 characters.

Marks. Anything you mark during a walk — the categories you pick, and any photo you attach — stays on your phone. Marks are not uploaded.

Your profile. A display name, a handle, and a photo if you add one.

Account details. Your email address, held by our sign-in provider. If you use Sign in with Apple you can choose to hide it, and we receive a relay address instead of the real one.


Where it goes

There is one place: our database, hosted by Supabase in Sydney, Australia. Holding New Zealanders’ information offshore is something we should tell you rather than bury, so: it is offshore, it is in Australia, and Supabase holds it under contract to handle it only as we instruct.

Every walk you save is uploaded once the app has worked out its coverage — the statistics, the note, the grid squares, and which audience you chose. That includes walks set to private. What stops anyone else reading a private walk is row-level security enforced by the database itself, not a filter in the app, and it is tested against a real database rather than a stand-in.

Your route line is never uploaded, at any setting, to anyone. The server has no column to store one. That is deliberate and it is the strongest guarantee in this policy: the cheapest way to be certain a route is never leaked is to have nothing to leak.


Who can see what

A finished walk is given to one of four audiences. They are four separate audiences, not a ladder. A friend does not see a walk you shared to a group they are not in, and a group does not see one you shared to friends.

  You Friends A group you shared to Anyone signed in
The line you walked On your phone only Never Never Never
The grid squares you covered Yes If shared to friends If shared to that group If shared publicly
Distance, duration, date Yes If shared to friends If shared to that group If shared publicly
Your note Yes If shared to friends If shared to that group If shared publicly
Display name, handle, photo Yes Yes Yes Yes
Coverage totals for an area Yes Yes Yes Yes

What sharing a walk actually reveals

A shared walk travels as the list of 65-metre squares it passed through. That is coarser than a route line — it does not show which side of a street you took, or where you doubled back, or how long you stood still — but it is still a record of where you were, with your name on it, for whoever you shared it with.

It is not trimmed at the ends. If a walk started at your front door, the square containing your front door is in that list. The Hide the start and end of my walks setting trims route lines, and no route line is uploaded, so today that setting does not change what a shared walk reveals. Until it does, treat sharing a walk that starts at home as telling that audience roughly where you live.

Keeping a walk private avoids this entirely: a private walk is visible to nobody but you.

The coverage map

The coverage map counts every walk, private ones included. That is the point of it — the ground that was prayed over, not the people who covered it.

What makes that safe is what the coverage figures do not contain: no account, no walk, and no time finer than a calendar day. A square reports how many distinct walker-days touched it and the most recent date. Two people on one street on one day is 2; one person walking it three times in a day is 1. There is no way to join two squares back into a journey.

There is no administrator view

No report exists, in the app or internally, that shows which member of a church walked where. There is no such report because there is no route to build one from. Group reporting is participation counts and coverage totals.


Finding people, and being found

Signed-in walkers can search for people by handle or display name, three characters minimum. Your display name, handle and photo are visible to anyone signed in who finds you.

Friend requests have to be accepted. A pending request grants nothing.

If you add a profile photo, our server re-encodes it to a 512-pixel square before storing it. Rebuilding the image from its pixels discards every piece of embedded metadata, including the GPS coordinates a phone camera writes into a photo. The file you uploaded is never stored, and there is no path by which an unstripped image can reach our storage.


Who else is involved

Supabase — our database, sign-in, and file storage, in Sydney, Australia.

LINZ Basemaps, run by Toitū Te Whenua Land Information New Zealand — the map imagery. Your phone asks LINZ for map tiles covering the area you are looking at, so LINZ sees which areas you view. It is not sent your walks.

Expo — delivers app updates over the air.

Apple and Google — the app stores, and the sign-in providers if you use them.

We do not use advertising networks, analytics SDKs, or third-party trackers.


Keeping and deleting

Walks are kept until you delete them or delete your account.

To delete your account, see our deletion page. Deleting in the app is immediate — you’re signed out straight away — and removal from our servers completes within 30 days.

Deleting removes your profile, your photo, your walks and their statistics, your notes, and your grid squares. If you’re the only owner of a group, the group — and everyone’s membership in it — is deleted along with your account.

The coverage totals you contributed are not reversed — a coverage count records that an area was prayed over on a given day. It has no person attached to it and cannot be traced back to you, so those counts stay. Other people’s records of their own neighbourhoods are built from the same totals, so removing yours would corrupt theirs. Nothing that identifies you survives deletion.

Data held only on your own phone goes when you delete the app. We cannot recover it for you.


Your rights

Under the Privacy Act 2020 you can ask what personal information we hold about you, ask us to correct it, and complain to the Office of the Privacy Commissioner if you think we have mishandled it.

For anything the app does not show you directly, contact us.


Children

ardeo is not directed at children under 13 and we do not knowingly collect their information.


Changes

If this policy changes in a way that affects what we do with your information, we will tell you in the app before the change takes effect.

What changed on 18 September 2026

The app changed a great deal after the first version of this policy was written on 26 August, and several things it said are no longer true. Rather than edit them away quietly:

What changed on 23 September 2026

Account deletion moved from an email-only request to in-app self-service, with email kept as a fallback for a lost phone or lost access to the address you signed in with. Deleting in the app is immediate — you are signed out right away, and removal from our servers completes within 30 days, rather than the 7-day human confirmation this page used to describe.

ardeo is in beta. The app is provided as-is while we test it, and some features described here arrive over the course of the beta.
