Privacy notice

In short

Who we are

Donkey Analytics runs Donkey Analytics and is the controller of your personal data: we decide how it is used.

For anything about your data, email privacy@mail.donkeyanalytics.co.uk.

What we hold, and why

WhatWhyLawful basis
Your email address and password hash To create your account, sign you in, and send password-reset and account email Contract
While a new account waits for its address to be confirmed: the address and the password hash To create the account once you open the link we mail you Contract
If you turn on two-step sign-in: the secret your authenticator app shares with us, and a fingerprint of each unused recovery code To ask for a code as well as your password when you sign in Contract
Your library: GPS tracks (the position and time of each point), instrument data, boats, polars, courses, races, calibration and settings To analyse your sailing, which is the service itself Contract
Billing: your Stripe customer and subscription IDs, the subscription's status, when your trial ends, and the boats you pay for To bill you, and to know what you have paid for Contract
Which version of the terms you accepted and when, and your request to start a subscription straight away To show what you agreed to Contract, and our legitimate interest in being able to show it
When you signed in and were last seen, and the sessions you signed out of To keep your account secure Legitimate interests (security)
How many requests and uploads your account makes each day To keep the service running fairly and plan its capacity Legitimate interests (running the service)
Server logs: your IP address, and the time and address of each request To stop attacks on sign-in and to find faults Legitimate interests (security)
Once your account is deleted: an anonymised copy of your tracks, without your name or your boat's (the boat becomes a code), without dates, and with the start and end of each track cut off To improve Donkey Analytics' analysis Legitimate interests (improving the service)
A record of what the people who run the service do to your account: each change, each look at your library and each copy, with who did it, when and from where So that what an administrator did can always be checked Legitimate interests (security and accountability)

You give us your email address and password when you sign up, and everything in your library when you import it. Without an email address and password we cannot give you an account.

Your tracks are location data

A track records where your boat was and when, often to within a few metres. Over time tracks can show where you keep your boat and when you are away from home. So:

Who else handles your data

These companies process data for us under contract:

WhoWhat forWhat they handleWhere
Hetzner Online GmbHHosting: runs the server and stores every library and accountEverything described aboveGermany or Finland (EU)
StripePayments, invoices and the subscriptionEmail address, billing address, card details (never seen by us), what you pay forUK, Ireland and the USA
The mail provider (smtp.resend.com)Sends password-reset and account mailEmail address and the mail's textSee the provider

Some pages load maps and charting code straight into your browser from these services. Your browser sends them its IP address and the map area you look at, and nothing from your account:

WhoWhat forWhat they seeWhere
OpenStreetMap Foundation (tile.openstreetmap.org)The base map under your tracksIP address and the map area you viewSee the provider
OpenSeaMapThe seamarks drawn over the mapsIP address and the map area you viewGermany

We share your data with nobody else, unless the law requires it (a court order, for example).

Data sent outside the UK

Our hosting provider, Hetzner, keeps everything in the EU, which UK law treats as protecting personal data adequately. Stripe is a company in the USA, and a map tile provider may serve from wherever is nearest to you. Where your data leaves the UK for one of them, it is protected by the UK's International Data Transfer Addendum to the EU standard contractual clauses, or by the UK extension to the EU–US Data Privacy Framework, whichever the provider offers.

How long we keep it

WhatHow long

Your rights

To use any of these rights, or to ask about them, email privacy@mail.donkeyanalytics.co.uk. We answer within one month.

If you are unhappy with how we handled your data, you can complain to the Information Commissioner's Office at ico.org.uk/make-a-complaint or on 0303 123 1113. We would like the chance to put it right first.

How we keep it safe

Cookies

We use one cookie, to keep you signed in, and no advertising or analytics cookies. The cookie notice lists everything the app keeps in your browser.

Automated decisions

Nothing about you is decided by a computer alone in a way that has legal or similarly serious effects on you.

Changes to this notice

When this notice changes, the version at the top changes with it. If a change affects how we use data you have already given us, we email you before it applies.
