Privacy Policy

Last updated: 21 June 2026

This Privacy Policy explains how MateSync ("we", "us", "our") collects, uses, stores, and discloses your personal information. We comply with the Australian Privacy Act 1988 and the Australian Privacy Principles (APPs).

1. Who we are

MateSync is an iOS application developed and operated in Australia. We can be contacted at hello@matesync.au.

2. What information we collect

2.1 Information you provide directly

• Account information: email address (used as your login), password (encrypted; we never see your plaintext password), and display name
• Profile information: profile picture (optional), short name, and your notification preferences
• Roster information: your work pattern (days on/off, anchor date, shift type), any custom patterns you create, and the names you give your rosters
• Connection information: the user IDs of mates you connect with via invite links
• Subscription information: if you upgrade to MateSync Pro, your subscription status, expiry date, and a purchase identifier issued by RevenueCat (our subscription management provider)

2.2 Information collected automatically

• Push notification token: a device-specific identifier provided by Apple, used solely to deliver push notifications to your device. This token cannot identify you outside the MateSync system
• Authentication metadata: sign-in timestamps and session tokens (managed by Supabase, our authentication provider)

2.3 Information we do NOT collect

• We do not collect your location
• We do not collect your phone number
• We do not use advertising identifiers (no IDFA)
• We do not track your activity across other apps or websites
• We do not collect financial information directly — Apple handles all payment processing for subscriptions

3. How we use your information

We use your information solely to provide the MateSync service:

• To create and maintain your account
• To calculate and display your roster, your mates' rosters, and overlap windows where you're all home together
• To deliver push notifications you've opted into (new overlaps detected, mate's roster changes)
• To process invite links between mates
• To manage your subscription status (if you upgrade to Pro)
• To respond to support requests when you contact us
• To comply with legal obligations under Australian law

We do not use your information for marketing, advertising, profiling, or any purpose beyond providing the service.

4. Who we share your information with

We do not sell your personal information. We share it only with the following service providers, strictly as required to operate MateSync:

• Supabase (database and authentication) — servers located in Sydney, Australia
• Apple Push Notification Service (APNs) (push notification delivery) — used only to deliver notifications you've opted into
• RevenueCat (subscription management) — used only for users who purchase MateSync Pro, to validate purchases and manage subscription state
• Netlify (web hosting for matesync.au) — does not have access to in-app data

Your mates can see your display name, short name, profile picture (if you've uploaded one), and current roster pattern. Mates cannot see your email address.

5. Where your information is stored

Your data is stored on Supabase servers in Sydney, Australia. Some service providers (such as Apple's push notification servers and RevenueCat) may process data outside Australia under their own privacy policies and applicable cross-border data transfer protections.

6. How long we keep your information

We retain your information for as long as your account is active. If you delete your account:

• Your profile, rosters, and connections are deleted within 30 days
• Anonymised metadata may be retained for security and abuse-prevention purposes for up to 12 months
• Records required by Australian taxation or consumer law may be retained for the legally required period

7. Your rights under the Australian Privacy Principles

You have the right to:

• Access your personal information held by us
• Correct inaccurate information (you can update most details in the app's Settings)
• Delete your account and associated data
• Lodge a complaint with the Office of the Australian Information Commissioner (OAIC) at oaic.gov.au if you believe we have breached the Privacy Act

To exercise any of these rights, email hello@matesync.au.

8. Security

We protect your information using industry-standard security measures including TLS encryption in transit, encrypted storage at rest, row-level security on our database, and secure authentication tokens. No system is perfectly secure, but we take security seriously and will notify you of any data breach affecting your information as required under Australian law.

9. Children's privacy

MateSync is not intended for users under 16. We do not knowingly collect information from anyone under 16. If you believe a child has provided us with information, please contact us and we will delete it promptly.

10. Changes to this policy

We may update this Privacy Policy occasionally to reflect changes to our practices or legal requirements. Material changes will be communicated in-app or via email. The "Last updated" date at the top of this page indicates when the policy was last revised.

11. Contact us

Questions, complaints, or requests about your privacy can be sent to hello@matesync.au. We respond personally to every email, typically within 24 hours on business days.
