Privacy policy
Last updated 11 October 2026
Quarterline is an app football clubs use to run their coaching: match stats, player profiles, feedback, team selection, training and club messages. This policy explains what personal information we handle, why, who else sees it, how long we keep it and the choices you have. We follow the Australian Privacy Principles in the Privacy Act 1988 (Cth).
Who we are
Quarterline is a business name of A.MO Advisory and Consulting Pty Ltd (ABN 56 687 316 203), South Australia 5082. In this policy, “we” and “us” means that business.
Clubs and Quarterline
Each club that uses Quarterline decides who joins, what is recorded about its players and staff, and who in the club can see it. We provide the app and look after the information on the club's behalf. A club only ever sees its own information: one club can't see another club's players, feedback, notes or votes.
Some information about you may be entered by your club before you ever sign in, for example your name and guernsey number from a match stats sheet. Your club is responsible for telling its players and staff that it uses Quarterline and for having a good reason to record what it records. If you have a question about what your club has recorded, you can ask your club or us.
What we collect
- Account details: your name, email address and a password, stored only as a one-way hash we can't read. Your role at the club (coach, Club Admin or player) and coaching title.
- Player profile, entered by your club: name, guernsey number, positions, team, photo, and optionally date of birth, height, weight, phone, email, emergency contact, club debut, previous club and a short bio.
- Football information: match and season statistics, benchmarks and ratings worked out from them, team selections, availability, training attendance, awards and video links.
- Coaching content: feedback from coaches, coaches' private notes, Best & Fairest votes (seen only by the Head Coach), scouting notes on opposing teams, match reports and announcements.
- Injury information: see the next section.
- Files: match stats PDFs, club logos and player photos uploaded by the club.
- Usage and security records: when you last signed in, notifications sent to you, a log of important changes (such as who changed a setting, invited someone or opened a club for support), failed sign-in attempts for rate limiting, and standard server logs (such as IP address and browser type) kept by our hosting provider.
- Club billing details: the club's plan, price, billing dates and a billing contact. Card or bank details are held by our payment provider, not by us.
- Enquiries from our website: when someone asks us to set up their club, their name, role at the club, email, phone (optional), the league and club, and their message, so we can contact them and arrange setup.
- Questions to the website assistant: questions typed into “Ask Quarterline” on our website are sent to our AI provider to answer them and are not stored by us. Please don't include personal details.
We only collect what the app needs. Optional profile fields can be left blank.
Injury and health information
Coaches can record injuries (the injury, dates, expected return and recovery notes) so they can manage the playing group safely. This is health information, which the law treats as sensitive. Only the club's coaches can see it; players and other clubs can't. A club should only record injury information with the player's consent (or a parent or guardian's for a player under 18), and only what it needs to manage selection and recovery. Injury details are never sent to our AI provider.
Why we use it
- To run the app for your club: showing stats and profiles, sending feedback, selections and announcements, and managing training and availability.
- To manage accounts, invitations, sign-in and security, including stopping misuse.
- To provide support when your club asks for help. When we open a club to help, it's recorded and the club can see it.
- To manage the club's licence and billing.
- To improve Quarterline using totals and counts, not by reading clubs' coaching content.
We don't sell personal information, and we don't use it for advertising.
How we use AI
Some optional features use an AI model from Anthropic (Claude) to help coaches write. Coaches choose to use them, and everything AI writes is a draft that a coach reads and can change before anyone else sees it.
- Player feedback drafts: the player's name, position and match statistics, how they compare with others, and the focus areas from their recent feedback are sent to help draft new feedback.
- Match report drafts: the match statistics and the team's top performers by name are sent to help draft the report.
- Player insights and questions about the stats: match and season statistics and player names are sent to answer a coach's question.
The “Ask Quarterline” assistant on our public website sends the visitor's question, and our published website content, to the same provider to write an answer. It can't see any club's information.
Injury information, Best & Fairest votes, coaches' private notes, contact details and passwords are never sent. Under Anthropic's commercial terms, information sent through our account is not used to train its models. Anthropic may keep it for a limited time to detect misuse. Each club's AI use has a monthly limit set by us. A club can ask us to switch the AI features off.
Who we share it with, and where
We use these service providers to run Quarterline. Each only gets what it needs to do its job, under its own privacy and security terms.
| Provider | What for | What it receives | Where |
|---|---|---|---|
| Supabase | Database and file storage | Everything stored in the app | Sydney, Australia |
| Vercel | Hosting the app | Pages and requests as they pass through, server logs | Sydney, Australia (app servers); worldwide network for delivering pages; company in the United States |
| Anthropic | AI writing features | The information listed under “How we use AI” | United States |
| Resend | Sending emails | Your email address, name and the email's content | United States |
| [Payment provider] | Club subscription payments | The club's billing contact and payment details | [Country] |
Some of these providers are overseas, mainly in the United States, so personal information may be accessed from or stored there. We choose providers with strong security and privacy commitments and take reasonable steps so they handle it consistently with the Australian Privacy Principles. We may also disclose information if the law requires it.
Match stats from your statistics provider
Clubs upload the match statistics files they receive from their statistics provider. Those files contain players' and opposing players' names, guernsey numbers and statistics. The provider owns that data and licenses it to the club. When a club uploads a file it confirms it's allowed to use that data in Quarterline for its own coaching. Opposing teams' statistics are only visible to the club that uploaded them.
Cookies and tracking
We use two cookies: one that keeps you signed in, and one that remembers whether you chose light or dark mode. The app also saves an offline page on your device so it can tell you when you've lost connection. We don't use advertising, analytics or tracking cookies, and fonts and images are served from Quarterline itself.
Players under 18
Some clubs have players under 18. Clubs should collect the minimum about them, get a parent or guardian's consent where needed (and always for injury information), and only invite a player under 18 to sign in with their parent or guardian's agreement. Player information is never public: it's only visible inside the player's own club.
Keeping it secure
- Information is encrypted in transit (HTTPS) and at rest by our database provider.
- Every request is checked against your role, and the database itself stops anyone seeing another club's information.
- Passwords are stored as one-way hashes. Sign-in, password reset and invitations are rate limited.
- Files are kept in private storage and only shown through short-lived links to people allowed to see them.
- Changing your password signs you out everywhere else, and a club can remove someone's access straight away.
How long we keep it
- While your club uses Quarterline, we keep its information so the club keeps its history (for example, past seasons' stats and awards).
- When a club leaves, it can ask for a copy of its data. We then delete the club's information and files within 90 days of its licence ending, unless the law requires us to keep something.
- Deleted accounts are de-identified straight away (see below).
- Sign-in links, password reset links and invitations expire within 14 days and are cleared out regularly. Failed sign-in records are cleared within 30 days.
- Notifications are deleted after 12 months.
- Website enquiries are kept while we're talking with the club and deleted within 12 months if the club doesn't go ahead.
- Backups made by our database provider roll over and are gone within 30 days.
Deleting your account and data
You can delete your account at any time in Settings → Your account → Delete my account. We remove your sign-in, your name and email, your club memberships, notifications and any pending invitations straight away, and your access ends on every device. If you're a player, your player profile and statistics stay with your club as part of its records, no longer linked to you; ask your club if you'd like your profile, photo or contact details removed, or contact us. Club records you wrote, such as feedback, stay with the club under “Deleted user”.
If you can't sign in, email amo@quarterline.com.au and we'll do it for you once we've confirmed it's you.
Seeing and correcting your information
You can see most of what's held about you in the app. Ask us at amo@quarterline.com.aufor a copy of all the personal information we hold about you or to correct anything that's wrong. We'll respond within 30 days. If we can't give you something, we'll explain why.
Emails we send
We send emails that are part of using Quarterline: invitations, password resets, and your club's notifications such as feedback, team selections and announcements. You can change which notifications you get by email in the app. We don't send marketing emails without your consent, and any we do send will have an unsubscribe link.
If something goes wrong
If we find a data breach likely to cause serious harm, we'll contain it, tell the clubs and people affected, and notify the Office of the Australian Information Commissioner (OAIC), as the Notifiable Data Breaches scheme requires.
Wellbeing and support
Quarterline isn't a support service. If you or someone you know needs help, please reach out:
- Lifeline: 13 11 14 (24/7 crisis support)
- Beyond Blue: 1300 22 4636 (24/7 support)
- Kids Helpline: 1800 55 1800 (ages 5 to 25, 24/7)
- Emergency: 000 (if life is in danger)
If anything written in the app suggests someone may be at risk, our AI features reply with these support details instead of a normal answer.
Questions and complaints
Contact us at amo@quarterline.com.au or South Australia 5082. We'll acknowledge a complaint within 7 days and aim to resolve it within 30 days. If you're not satisfied, you can complain to the Office of the Australian Information Commissioner: oaic.gov.au, 1300 363 992.
Changes to this policy
We'll update this policy when how we handle information changes. We'll show the new date at the top and tell clubs about significant changes before they take effect.
