Chinook Maps

Privacy policy

Last updated: 7 September 2026

Chinook Maps is a map and navigation app built from Canadian government open data. This policy explains what it collects, what it does not, and what you can do about it. It is written to be read, not to be survived.

This policy applies to everyone, everywhere. The maps cover Canada, but the app is distributed worldwide and the same rules apply wherever you are. Where your local law gives you a right this policy does not name, you have that right too.

Who is responsible. Chinook Maps is published by an independent developer, contactable at privacy@chinookmaps.com. For the purposes of the UK and EU GDPR that developer is the data controller for anything described here.

The short version

route, and that is all.

Nothing else.


What is collected, in Google Play's terms

Play's Data safety form uses fixed categories. This is the same information as the rest of this page, expressed in those categories so the two cannot drift apart:

Play category Collected? Shared? Purpose
Location (approximate and precise)No — used on device only, never transmittedNoDraw your position, plan a route
Personal info — Email addressOnly if you create an accountNoSign-in and account recovery
Personal info — Name, address, phoneNoNo—
App activity — Saved places, recent searchesOnly if you create an accountNoSync your own list between your devices
App info and performance — Crash logs, diagnosticsNoNo—
Device or other IDsNoNo—
Financial, health, messages, photos, contacts, calendarNoNo—

Nothing in this app is sold, and nothing is shared with a third party for advertising or analytics. There are no advertising, analytics or social SDKs in the build.


What is collected

If you never make an account — nothing

The app has no account requirement. Used signed out, Chinook Maps sends no personal information anywhere. Region packs are downloaded from a file host, which necessarily sees the request and your IP address as any web request does; that is a server log, not a profile, and it is not linked to you.

If you make an account

What Why Where it is stored
Email addressTo identify your account and let you sign inSupabase, Canadian region
PasswordStored only as a salted hash; we never see itSupabase, Canadian region
Saved places (name, coordinates)So they appear on your other devicesSupabase, Canadian region
Recent searchesSo they appear on your other devicesSupabase, Canadian region

That is the complete list.

What is never collected


Location

Chinook Maps asks for location permission so it can show where you are on the map and plan a route from where you are standing.

That location is used on the device and is never transmitted. Routing happens against a graph stored on your phone; there is no server to send a position to. If you decline the permission the app still works — you can pan the map and plan routes from any point you choose.

The app requests only foreground location. It does not request background location and does not track you when it is closed.


Where your data is held

Account data is stored with Supabase in a Canadian region (ca-central-1), so it does not leave the country in normal operation.

Access is enforced by PostgreSQL Row Level Security: every row is readable only by the account that owns it. This is enforced by the database, not by application code, so a bug in the app cannot expose another person's data.


Why we are allowed to hold it

If you never create an account there is nothing to justify, because nothing is collected. If you do, the legal bases under the UK and EU GDPR are:

What Basis
Email address and password hashContract — an account cannot exist without them
Saved places and recent searchesContract — they are the feature you asked for
Keeping the service secure and workingLegitimate interests, balanced against your privacy

There is no processing based on consent for advertising or profiling, because there is no advertising or profiling. Nothing here involves automated decision-making.


Your rights

These apply to everyone using the app, wherever you live. Different laws give them different names — the UK and EU GDPR, Canada's PIPEDA, Quebec's Law 25, California's CCPA/CPRA — but the substance below is what you get from us regardless of which one covers you.

there is nothing to withhold

Exercising any of these costs nothing and we will not ask you to justify it. We answer within 30 days.

California. We do not sell or share personal information as CCPA/CPRA define those terms, and we have never done so.

Deleting your account

In the app: About → Account and saved places → Delete account. This removes your account, your email address, and every saved place and recent search, permanently and immediately.

Without the app, if you have uninstalled it or lost the device: https://chinookmaps.com/delete-account, or email the address below. We will action the request within 30 days.

Deletion is real deletion. Nothing is retained in a "deleted" state, and there are no backups kept for the purpose of restoring erased accounts.


Children

Chinook Maps is not directed at children and does not knowingly collect information from anyone under 13. If you believe a child has created an account, contact us and we will delete it.


Security

tampered or corrupted map file is rejected rather than used.

unavailable, the app tells you so rather than staying quiet about it.

on a device.

No system is perfect. If a breach occurs that creates a real risk to you, we will tell you directly and notify whichever regulator is responsible for you — within 72 hours where the GDPR sets that deadline, and without undue delay everywhere else.


Third parties

Chinook Maps contains no advertising SDKs, no analytics SDKs, and no social SDKs. It does not use Google Play Services.

Two services are involved in running it:

file download does. It is a content network, not an analytics provider.

Where your data goes

Account data is stored in Canada and nowhere else. If you are in the UK or the EEA, that is a transfer out — Canada holds a partial adequacy decision from the European Commission covering commercial organisations, which is the basis we rely on. Map files are served from a global network, but a map tile is public data and says nothing about you beyond the request itself.

How long it is kept

What Kept for
Account, email, saved placesUntil you delete the account — then gone immediately
Deletion requests sent from the web form12 months, so we can prove the request was actioned
Server request logs at the file hostCloudflare's own retention, days rather than months

There is no archive, no backup kept for restoring deleted accounts, and no shadow copy.

Map data comes from the Government of Canada and the City of Calgary under open government licences. Those are data sources; nothing about you is sent to them.


Changes

If this policy changes materially, the app will say so before the change takes effect. The date at the top always reflects the current version.


Contact

Email: privacy@chinookmaps.com — for anything on this page, including any of the rights above.

If you are not satisfied with how we handle it, you can complain to the privacy regulator where you live. In the UK that is the ICO, in the EEA your national data protection authority, and in Canada the Office of the Privacy Commissioner. You do not need our permission and you do not have to come to us first, though it is usually faster if you do.
