Privacy Policy

Effective 22 July 2026

Harbourside Apps Pty Ltd ("Harbourside Apps", "we", "us" or "our") provides Offset, an iPhone app that creates flight-aware sleep and body-clock plans. This policy explains how we handle personal information when you use Offset, our website or support.

Information we collect

Identity and account information

• A random user and installation identifier, session credentials and account status.
• If you choose Sign in with Apple or Google, the provider's stable account identifier and any name or email address the provider supplies with your consent.
• Your support messages and contact details when you ask us for help.

You can use Offset without adding an Apple or Google login. Adding one lets you recover your Offset data and use it on another device.

Journey and planning information

• Flights you search for or add, including flight numbers, airports, dates and times.
• Your journeys, saved flight details, plans, plan events and related app choices.
• Your usual sleep time and duration, and your choices about caffeine, melatonin and preparing before travel.

Offset uses this information only to create, save, update and deliver your travel plan. We do not use it for advertising.

Calendar access

If you grant calendar access, Offset reads upcoming events on your device to find possible flight numbers and dates. Calendar event titles, notes, attendees and full event contents stay on your device. Offset sends a flight number and date to our service only after you select or search for a suggested flight. You can remove calendar access at any time in iOS Settings.

Purchase information

Apple handles payment details. We do not receive your card number. We and RevenueCat receive information needed to provide Pro access, such as your Offset user identifier, product, purchase status, entitlement status, expiry and whether access came through Family Sharing.

Technical information

Our hosting providers may process IP addresses, request times, app and operating-system versions, error details and security logs when the app contacts our service. Offset does not currently include a third-party advertising or product-analytics SDK.

How we use information

• Provide, sync and restore Offset and its offline data.
• Create plans and update them when selected flight data changes.
• Manage free and paid access, purchases and restores.
• Protect accounts, prevent misuse, diagnose faults and keep the service reliable.
• Answer support requests and comply with law.

Who receives information

We do not sell personal information. We use these service providers where needed:

• Cloudflare for the website, API, network security and delivery.
• DigitalOcean for managed database hosting.
• AeroDataBox to find and refresh flight information.
• RevenueCat and Apple to process and manage subscriptions and entitlements.
• Apple and Google when you choose their sign-in service.

We may also disclose information when the law requires it, to protect a person from harm, or to protect our rights and service. Providers process data under their own terms and privacy duties.

Overseas processing

We are based in Australia, but our providers may process information in other countries. Our main database is hosted in the United States, and global providers may process information in the United States and other places where they operate. Privacy laws in those places may differ from Australian law.

Storage, security and offline use

Offset keeps a local copy of key profile, journey and plan data so the app remains useful when the network is unavailable. Session credentials use protected device storage. Our service uses access controls and encryption in transit. No system can guarantee complete security.

Retention and deletion

We keep your Offset data while your user record exists so we can provide sync, recovery and journey history. When you delete your user in the app, Offset immediately and permanently removes the user and associated Offset-owned sessions, logins, profile, journeys, plans, installations and entitlement records from the live service. The app also clears its local Offset data.

Provider-owned purchase records remain with Apple and RevenueCat as required to manage purchases, refunds and legal duties. Security logs and backups may remain for a limited period under our providers' normal retention schedules before they expire. We may keep information where law requires it.

Read the account deletion instructions.

Your choices and rights

You can:

• Edit your planning profile in Offset.
• Remove calendar or notification permission in iOS Settings.
• Ask to access or correct personal information we hold about you.
• Delete your user and Offset-owned data in the app.
• Contact us with a privacy question or complaint.

Email support@harboursideapps.com. Please explain what you need and include enough detail for us to find the right user. We may need to verify your identity before giving access to or changing personal information. We will acknowledge privacy complaints and respond within a reasonable time. If you are not satisfied, you may contact the Office of the Australian Information Commissioner.

Children

Offset is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has given us personal information, contact us so we can investigate and delete it where required.

Changes to this policy

We may update this policy when Offset or our data handling changes. We will post the new policy here with a new effective date and give added notice in the app when a change is material.
