Privacy policy · A320 Knowledge

This policy explains how A320 Knowledge (a320knowledge.com) handles your personal data. You can reach us about anything in it at hello@a320knowledge.com.

What we collect

Your account. Your name and email address, and your password, which we store only as a one-way hash we can't read. If you sign in with Google, we receive your name, email address and Google account identifier, and nothing else from your Google account.
Your profile, if you add it. Your role (for example cadet, first officer or captain), your airline and your type rating course date. All optional.
Your training progress. Your answers, scores, flags and notes in the training tools. Without an account these stay in your browser only. With an account we keep a copy so your progress follows you between devices.
Payments. Payments are taken by Stripe. We never see or store your card details. Stripe tells us your name, email address, billing country and what you bought, so we can give you access and keep the records the law requires.
Questions to Ask the Manuals. The question you type is sent to our server and to our AI provider to write the answer. We don't attach your name or email to it. If you ask your own FCOM, the file stays on your device; only the passages that match your question are sent with it.
The interview coach. The answers you give are sent to our AI provider for its feedback. We don't keep them, and our AI provider doesn't use them, or your questions, to train its models.
Shared flight decks and lessons. A long link to the Interactive Flight Deck is kept on our server as a short code for 400 days, with nothing about you. In an instructor's lesson, your deck, how your drills went and the name each of you types pass through our server while the lesson is open, for 4 hours at most, and nothing of it is kept after.
Emails. Your email address and your email choices: the Tech Quiz (monthly on the free plan, weekly with A320 Knowledge+), an email when a new article comes out, and news, if you've asked for it. We also keep a note of which account emails we've sent you, such as a receipt or a reminder, so none is sent twice.
Emails you send us. When you email hello@a320knowledge.com we answer with AI assistance: your email is kept on our server for 90 days, with the names and sizes of any attachments but not the files, and its words may be sent to our AI provider, Anthropic, to help us draft the reply, which we read before it's sent.
Offer codes. If you use an offer's code, we keep a note that your account opened checkout with it and whether you paid with it, so each code is used once and we can count how an offer did.
Readers of our earlier newsletter. If you subscribed to our newsletter on Substack, we've made an account here for your email address, so you keep receiving the Tech Quiz and our new articles (and, if you were a paying member, so your membership carries on). It holds your email address, when you subscribed, whether you paid and whether you'd turned its emails off. It has no password until you set one, and you can delete it at any time from your account page, or by emailing us.
Technical data. Our hosting keeps short-lived logs of requests (such as the time, the page and your IP address) to keep the site secure and working. To keep the free plan's daily limit on Ask the Manuals when you're not signed in, we count your questions under a one-way code made from your IP address. To stop anyone guessing passwords, we count wrong log-in attempts under one-way codes made from the email address typed and the IP address, and we remember, also as a one-way code, the networks your account has logged in from. We also count visits to our pages ourselves, with no cookie: each day, how many pages were opened and how many different visitors came, each visitor under a one-way code made from your IP address, your browser and the date, so it changes every day and can't follow you from one day to the next. We don't use any other analytics, advertising or tracking cookies, and we don't sell your data.
The community, if you join it. The nickname you choose, whether you're on the weekly leaderboard and whether your study streak shows beside your nickname, your scores in the weekly round (each answer, the score and the time taken), and, if you make one, your sim partner card, the requests between you and other members, who you've blocked, and any report you send or that is sent about you. Nothing of it exists until you join.
Our own records. When we change an account by hand (for example to give access or to delete it), we keep a note of what we did and the account's email address, so we can account for it later.

Why we use it, and our legal basis

To provide your account, the training tools and the plan you've chosen, including the Tech Quiz that comes with it, an email when a new article comes out, and the emails your account needs (confirming your email, receipts, reminders and security notices): performing our contract with you.
To take payments, keep accounts and meet tax law: our legal obligations.
To keep the site secure, prevent abuse and fix problems: our legitimate interests.
To keep sending the Tech Quiz and our new articles to readers of our earlier newsletter, who subscribed to it: our legitimate interests. You can stop it at any time.
To send news you've asked for: your consent, which you can withdraw at any time.
To run the community you've joined (the leaderboard, the sim partner finder, the reminder before your card ends if you ask for it) and to keep it safe, through reports and moderation: your consent, given when you join, which you withdraw by leaving, and our legitimate interest in keeping the community safe.

You can stop the Tech Quiz, the new article emails or news with the link in every one of those emails, or in your account settings.

The community: what's shared, and with whom

Everything in the community is off until you join it, and you can leave at any time.

On the leaderboard, if you turn it on: your nickname, your points, how many you got right and the time you took each week, your weeks in a row and, if you choose, your study streak. Every member who has joined the community can see the board. Your name and email address are never shown.
On your sim partner card, if you make one: your nickname, what you're preparing for, your target months, the aircraft, your stage of training, your languages, your country (never a city) and how you'd like to practice. Members who have joined can see it until the end of its last target month, unless you hide it or have blocked them.
Your contact (your account's email, or a messaging handle you type) is shown only to a member whose request you have accepted, or who has accepted yours, and only while that connection lasts. Nobody sees it before you have both accepted.
Reports are seen only by our moderators, never by the member reported. A block isn't shown to the member you block.

To delete all your community data at once (your nickname, scores, card, requests, connections and blocks), choose Leave the community on the Community page or Delete my community data on Your account. If our moderators have closed the community features to your account, we keep a note of that, so it can't simply be undone by leaving and joining again; it is deleted with your account.

Cookies and storage on your device

We set four cookies, each only for something you've asked the site to do:

Signing in keeps you signed in, for up to 30 days.
Google sign-in lasts the ten minutes it takes to sign in with Google.
The flight deck taster remembers when your free taster of the Interactive Flight Deck started, for a day.
Your language remembers the language you read the site in, for a year, so our messages to you are in it too. If you have an account, the language you choose is also kept with it, so our emails to you come in that language.

Your browser's own storage holds your settings, your progress, your recent questions to Ask the Manuals and, if you import it, your own FCOM, and the site keeps a copy of its pages so it works offline. None of this is used for analytics or advertising, so we don't ask for consent: the site can't do these things without them.

Our pages load their typefaces from Google Fonts, so your browser connects to Google, which sees your IP address.

Our Videos page shows each video's picture from YouTube's image server, which also sees your IP address. A video's player loads only when you press play: it comes from YouTube's privacy-enhanced mode (youtube-nocookie.com), and from then on YouTube's own privacy policy applies to it.

Who processes your data for us

We use a small number of trusted services, each only for its part:

Cloudflare: hosting the site, storing your account and keeping the request logs.
Stripe: payments, tax and invoices.
Resend: sending our emails.
Google: signing you in, if you choose Google, and the site's typefaces.
Anthropic: the AI that writes Ask the Manuals' answers and the interview coach's feedback, and helps us draft our replies to your emails.

Some of these services process data outside the UK, including in the United States. Where they do, the transfer is protected by the UK's approved safeguards, such as the International Data Transfer Addendum or the UK-US data bridge.

How long we keep it

Your account, progress and Tech Quiz history: while your account is open. Delete your account and we delete them straight away; copies in our host's backups are gone within 30 days.
Our own weekly backup of the accounts (so they can be restored if something goes wrong): kept privately by us, and each copy deleted within 90 days. It never holds passwords.
After you delete your account we still keep: payment and tax records (with Stripe and in our accounts) for six years, as UK law requires; the note of which account emails we sent, and whether an offer's code was used, under a random number with no name or email address; and our own record of changes we made to your account by hand, with its email address.
Being signed in: up to 30 days at a time. Links in our emails stop working after one hour to 14 days, depending on the link.
Questions to Ask the Manuals and their answers: up to 7 days in our logs and answer store, so we can check answers and fix problems. The count for the free plan's daily limit: two days. With A320 Knowledge+, your account's count of questions each day is kept with your account, and its count over the last few minutes (which stops anyone asking very fast) only for those minutes.
Server logs: up to 7 days.
The community: while you're in it. A sim partner card is hidden at the end of its last target month and deleted 60 days later; requests that were declined, withdrawn or ended are deleted after 90 days. Leave the community, or delete your account, and the rest goes straight away. A report you sent stays with our moderators until it is dealt with, without your name on it.
The one-way codes that guard log-ins: wrong attempts, a day; the networks an account has logged in from, 90 days.
Our count of visits: the day's one-way visitor codes, two days; after that only each day's totals are kept, with nothing about anyone.

Your rights

Under UK data protection law you can ask for a copy of your data, ask us to correct or delete it, object to or limit how we use it, and take it elsewhere. You can see your progress on Your progress, delete your account yourself on Your account, or email us for a copy of your data or any of these. If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk, though we'd like the chance to put it right first.

Children

A320 Knowledge is for pilots and people training to be pilots. It isn't meant for children under 16, and we don't knowingly collect their data.

Changes

If we change this policy in a way that matters, we'll update the date at the top and tell account holders by email.
